Nutrition Tips for a Plant based Diet

Leave a comment

Eating a more plant based diet or switching to a vegan diet is definitely on trend right now and whilst normally I’d not be recommending you jump onto the lastest fad in terms of nutrition, this is one I do agree with. I spoke about this at Womens Health Live so thought it was time I blogged on it too.

We all need to be doing our bit to help our planet. Eating more plants, preferably those grown locally and not wrapped in lots of plastic, is one step in the right direction towards a more sustainable diet.

But are there any nutrition concerns with eating a vegan, vegetarian or plant based diet? Whilst it is well known there are health benefits there are also some health risks if you are not consciously eating certain nutrients.

CALCIUM

If you are reducing your dairy intake then you are also reducing your calcium. To help with this check that the milk you use is fortified and focus on non-dairy calcium rich foods being in your diet. The higher calcium content foods are chia seeds, fortified plant based milks, yoghurts and tofu.

An adult needs 700mg calcium per day, the requirements are higher if you are breastfeeding.

IODINE

The body needs iodine to make thyroid hormones which play a key role in metabolism. Iodine is also needed in pregnancy for proper bone and brain development. There is an rise in iodine deficiency in the UK so it’s a nutrient to be mindful of.

Iodine deficiency is a potential concern if you do not eat meat, fish or dairy, so it’s important to be aware of other sources of iodine. Symptoms of iodine deficiency can include a swelling in the neck where the thyroid hormones are struggling to be made so the thyroid gland is on overdrive, fatigue and weakness, inability to concentrate/recall information, hair loss and dry flaky skin.

All is not lost, you can get your iodine in. Firstly, check your plant based milk as some are now fortified with iodine. Iodised salt is a good option (but not too much salt of course 6g max a day), seaweed limited to once a week and dried prunes are other options.

See this great food fact sheet on Iodine.

IRON

A nutrient that comes up a lot in terms of vegan and vegetarian diets. Can you meet all your iron needs on a plant based diet? Yes, totally but you need to plan things and be on the ball.

The iron you get in plant based foods is less readily absorbed by the body so you need more of it (1.8x). If you focus on eating iron rich foods daily and utilise some top tips you should be fine.

Iron Rich FoodsIron/mg
Baked beans1.4
Butter beans1.5
Chickpeas2
Kidney beans2
Tofu1.2
Dried Figs3.9
Dried Apricots3.4
Almonds3
Brazil Nuts2.5
Smooth peanut butter2.1
Hazelnuts3.2
Sesame seeds10.4
Sunflower seeds6.4
Broccoli 1
Spinach1.6

Including vitamin C with a meal helps with absorption. So having a glass of fruit juice or a smoothie with an iron rich meal will help. Keep your tea and coffee away from meal times as these contain phytates which prevent the iron absorption. Cooking, soaking and sprouting your nuts, seeds and beans can help with absorption too.

For more on iron check out the British Dietetic Association Factsheet.

VITAMIN B12

Mainly found in animal products with a few exceptions of fortified foods (fortified milks, nutritional yeast and breakfast cereals) this is one that you are going to need to take a supplement of if you stop eating animal products.

B12 is needed for nerves, for DNA production and for brain function as well as healthy red blood cell production. A pretty key nutrient. If you aren’t eating many fortified foods then you likely need a supplement which you can buy as part of a multivitamin and mineral over the counter. Chat to your medical team if you have any further concerns as there are also B12 injections.

So can you meet your nutritional requirements on a plant based diet? Yes with some careful planning and a couple of supplements. Remember you do not have to go fully vegan, eating a few days a week in this way has benefits.

The misconception of sugar.

Leave a comment

By Rosie Jasper, student dietitian.

Many thanks to Rosie for this blog post. Carbs are a huge topic that I myth bust on and talk to clients about every week… so I know you will find this helpful.

 I don’t know about you but I’m sick and tired of seeing celebrities, Instagram influencers and articles in the media encouraging us to cut out key components of our diets, for example carbohydrates!
Apparently cutting out sugar and therefore carbohydrate sources is the key to losing weight according to some top celebrity influencers such as Jennifer Lopez, who was promoting a 10 day no sugar, no carbohydrate challenge!

Sugars are carbohydrates; when we consume foods containing carbohydrates (such as those previously mentioned), our bodies break these down into simple sugars called glucose. Glucose is an essential part of our diet as it provides our body, including our brain with the energy it requires to function on a daily basis.

Carbohydrate containing foods also contain essential vitamins and minerals that are required to keep our bodies working as effectively as it should; a lack of nutrients could cause lead to a decrease in energy, mood and brain function. A decrease in mood may mean that we’re more likely to opt for ‘comfort foods’, that are often high in fat, salt and refined sugar, which defeats the object of the aimed weight loss and the vicious cycle begins. Therefore, by cutting out all carbohydrates in the diet, it’s subsequently removing important nutrients our bodies need.

As suggested by the Eatwell Guide, a third of the food we consume should be starchy foods and carbohydrates should form 50% of our energy intake daily. It is recommended that when choosing starchy foods, we should opt for wholegrain varieties where possible instead of their white/refined varieties. 

Examples of wholegrains:

  • Wholegrain bread
  • Wholegrain pasta 
  • Brown rice 
  • Quinoa 
  • Bulgur 
  • Wheat based cereals e.g. – Wheat biscuits, Bran Flakes, muesli (opt for the no added sugar or salt variety) 

White/refined products have been processed and includes foods like white bread, white pasta and white rice. During processing many of their nutrients including B vitamins, vitamin E, fibre and minerals are removed; however, we need all of these nutrients as they provide many health benefits such as providing energy, having antioxidant effects, keeping our digestive system healthy and for maintenance of bone, teeth, nerves, hair etc. Wholegrain carbohydrates include the whole grain and therefore maintain its nutrients. 

Carbohydrates do not naturally lead to weight gain if eaten in moderation, however it is true that eating carbohydrates excessively can lead to an increase in weight. Carbohydrates have many important roles in the body and shouldn’t be avoided due to the fear of weight gain.

The important role of carbohydrates in the body:

  • Our main source of energy – starchy foods are broken down more slowly than free sugar products and therefore provides us with a steady release of energy during the day 
  • Brain function – the brain requires a steady glucose supply in order to function properly 
  • Wholegrain starchy products contain B vitamins, vitamin E, fibre and minerals 
  • Fruits and vegetables contain naturally occurring sugar and are packed with essential vitamins and minerals to help keep our bodies healthy 
  • Fibre is a type of carbohydrate and helps to keep our digestive system healthy, reduce likelihood of constipation, reduce cholesterol and a diet high in fibre has also been associated with a lower risk of bowel cancer 
  • A diet low in carbohydrates is associated with low energy levels, a decreased brain function and low mood 

It is recommended that we aim for 5 portions of starchy foods per day (260g).  To put it in to perspective this is what 1 portion of a starchy carbohydrate looks like. An easy portion guide is for your cooked carb to fill your cupped hand. There is no need to weigh foods out each time you cook then, just weigh it once and find something it fits in like a tea cup to use as a household measure.

  1. 50 dry oats/ ½ cup
  2. 2 wheat biscuits 
  3. 1 slice of bread
  4. 1 bagel 
  5. 1 naan bread
  6. 100g dry cous cous/ ¾ cup/approximately 2 hands full
  7. 75g dry pasta/ ¾ cup/approximately 2 hands full
  8. 75g spaghetti (when bunched together should be the same width as a £1 coin)

The portions of pasta, cous cous and oats may look small when uncooked but when water is added to them and they are cooked, they increase in size and weight. Then when vegetables and/or lean meat is added the portions will bulk out more to create a balanced dish. Meals should be based around starchy foods and adding extra ingredients will contribute to a healthy, balanced diet and increase the nutrient content. 

Fibre is also a type of carbohydrate that is found in plant-based foods, however it’s not absorbed or digested and therefore doesn’t impact our blood sugar levels, so doesn’t need to be classed as part of your daily CHO. 

Benefits of fibre:

  • Promote regular bowel movements 
  • Prevents constipation 
  • Helps to control blood glucose levels 
  • Reduces cholesterol 

Wholegrain varieties of starchy foods, fruit and vegetables especially when eaten with their skin on, e.g. – potatoes, apples and pears are all excellent sources of fibre. 

Meal ideas including their carbohydrate and fibre content

Meal Carbohydrate content (g) Fibre content (g)
50g oats made and water 80g berries 37 6
2 wheat biscuits 135ml semi skimmed milk  Sliced banana 53 5
Wholegrain bagel Low fat spread Salmon Cottage cheese  42 7
2 slices of wholegrain toast  Low fat spread  Peanut butter  31 7
75g dried pasta ½ tin of chopped tomatoes 80g peas 80g broccoli 20g spinach  64 16
Medium sized jacket potato  ½ tin of baked beans  30g cheddar cheese 63 15

T

Endorsement of faddy diets in the media should be taken with a pinch of salt (or sugar in this case!), remember a lot of these people have personal dietitians, chefs, personal trainers, photoshop and surgery to achieve their ‘dream bodies’ that you see online. Removing main food groups, even for a short period of time is not healthy or sustainable and shouldn’t be encouraged.

Eating for a healthy gut

Leave a comment

PRE/PROBIOTICS – EATING FOR A HEALTHY GUT

Huge thanks to Melissa Kuman for this guest blog. Melissa is a Registered Associate Nutritionist. She can be found on instagram or check out her blog.

TOP FACT! Can you believe that the bacteria inside us can weigh up to 2kg and around 10% of what we eat feeds them?

In a nutshell, you can improve your gut by eating certain prebiotic foods and/or take probiotics. This is important as a lot of our immunity is dependent upon our gut (70% of the immune cells are located in the gut) and the microbes that live in it. Plus, 90% of serotonin, the happy hormone is produced in the gut. So basically good nutrition = healthy gut= serotonin and immune system= happy mind and body! Now lets get into this in a bit more detail… 

What is the difference between pro and prebiotics?

Great question! Well probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host FAO/WHO (2002). Where as prebiotics are certain fibrous foods (like banana, onions and oats) that help feed the bacteria.

What do probiotics do?

Probiotics rarely colonize in the gut, but rather intermingle with microbes there. As they go through the gut, they interact with gut cells, immune cells and food, giving their benefits. There’s so much research talking about the benefits of probiotics! Studies show that probiotics can improve digestive health and our immunity, including: decreasing antibiotic‐linked diarrhoea; improving resilience to infections; and improving digestion of lactose. There is even some early evidence of benefits in weight management and glycaemic control, depression and anxiety (Jacka 2017).

There’s no harm in taking probiotics but they’re quite expensive, so you could go for prebiotic foods that help feed the good bacteria like oats, bananas, onions, greek yoghurt and Kombucha.

It is important that the probiotics you are taking have research on the certain bacteria they include and that a health benefit has been proven. 

Prebiotics

Prebiotic foods are fibrous foods but not all fibrous foods are prebiotic, see table below. Overall, we need 30g of fibre a day and on average, in the UK, we are consuming just 18g. Both observational and interventional studies show that fibre influences gut health. As Burkitt, 1972 said ‘Dietary fibre has a role in the prevention of certain large bowel and other diseases present in Western countries’. Prospective studies also show it can decrease the risk of bowel cancer and insulin resistance in type 2 diabetes.

So how can we increase our fibre? Why not try eating more nuts and seeds and whole fruit and vegetables. For example you could add banana onto your morning cereal and make a big pot of vegetable curry with whole grain rice.

Interestingly Tim Spector, Professor of Genetic Epidemiology at King’s College London followed his son’s ‘Fast Food Diet’ to investigate the changes in the microbiota over the 10 day period. Tim ate 2 x Large McDonalds Meal [Big Mac/chicken nuggets, fries & Cola], 1 packet crisps & 2 beers for 10 days. After the 10 days, he lost nearly 40% of bacterial species with the good bacteria diminishing. Tim felt constipated, tired and grumpy. Not surprising really.

Other factors influencing the gut

‘Exposure to stress, both physical and psychological can modify the composition of the microbiota, due to increased permeability of the gut, allowing opportunistic bacteria to grow and potentially cause damage.’ Rhee et al. (2009).

It is important to put a bit of self-care into your day to reduce stress like running a bath and to be mindful when eating. Both these can help you have a happy gut.

Prebiotics Probiotic 
banana Yakult- Lactobacillus casei shirota
chicory Codex- Saccharomyces Boulardii
onion Actimel- Lacobacillus Casei
asparagus Mutaflor- Escherichia Coil Nissle
garlic Dicoflor- Lactobacillus rhamnosus

Cocoa Kimchi
Flaxseeds Miso

How much salt should I eat?

1 Comment

Salt Awareness Week is the  4th-10th March making there no better time to discuss salt! Why do we need salt, why are we consuming too much, what are the dangers of this, and how can we go about reducing our intake?  Huge thanks to Hannah Collins AfN for this guest post. 

Top tips on salt and how to eat lesss

What is salt, how much do we need & why?

Salt is another name for sodium and you may see either term used on food packaging.  We need a certain amount of salt in our diet to regulate the amount of water in our bodies – when this water balance is disrupted by too much salt it can have negative consequences on our bodies.  It is recommended that we consume maximum daily salt intakes of:

  • 6g for adults and children aged 11+ years which is about 1 teaspoon (2.4g sodium) 
  • 5g for children aged 7-10 years  (2g sodium)                         
  • 3g for children aged 4-6 years  (1.2g sodium)
  • 2g for children aged 1-3 years  (0.8g sodium)

We need to be careful when reading food packaging to check whether the salt is labelled as salt or sodium to avoid confusion. It is very hard in a western diet to consume insufficient salt for our needs.

How much are we actually consuming?

The average adult in the UK consumes about 8g of salt per day.  This is much reduced vs 10 years ago but this 8g is still about one third more than we need.

Why does too much salt cause us problems?

  1. High Blood Pressure

Consuming more than 6g of salt per day can cause many health problems, the greatest of which is high blood pressure, also known as ‘hypertension’.  When we eat too much salt, this salt holds on to water in our bodies and disrupts the all-important water balance I mentioned earlier.  As blood is mainly water, this extra water in our blood puts greater pressure on our blood vessels to open up and let the blood through – resulting in high blood pressure!  

High blood pressure is a risk factor for cardiovascular disease – it puts extra strain on your heart to pump your blood around the body and may result in a heart attack or stroke if the pressure is very high.

The government states that if we were to reduce our salt intake to the recommended 6g per day, there could be up to 20,000 fewer deaths from heart attack and stroke each year! 

Salt reduction combined with a diet:

  • High in fruit & veg, wholegrains, low fat dairy and pulses
  • With small daily amounts of lean poultry & fish

has been proven to be the best way to reduce high blood pressure. This diet is known as the DASH diet (Dietary Approaches to Stop Hypertension)

  1. Kidney Problems

If salt holds on to water in your body, the kidneys do the opposite job – they have to try and get rid of this excess water to keep a nice water balance for us.  

image1.gif

More salt in the blood means the kidneys have to work a lot harder to try and remove the water, as the water likes to stay with the salt!  Over time this can put a lot of strain on our kidneys and can lead to kidney failure where the kidneys slowly stop working properly.

Once kidney failure is established it cannot be reversed and patients must consume even less salt at this stage to avoid total failure or dialysis.

Too much salt can also make us dehydrated and affect our day to day performance.  It can also cause painful kidney stones and stomach ulcers.

pastedGraphic.png

Tips to consume less salt

Most of us won’t have the time or the inclination to calculate how much salt we are eating every day!  To keep it simple:

  • Don’t add salt to food when cooking; replace with herbs & spices (dry or fresh), lemon, lime or garlic
  • 75% of the salt we eat comes from ready meals/soups/sauces/breads – i.e. processed foods.  Quickly scan the packaging of processed foods when buying and opt for foods that have the ‘green’ traffic light for salt. Foods that carry the red light should be consumed sparingly.
  • For foods that have no traffic lights, you can use the FoodSwitch app which is free to download.  By scanning the barcode it will tell you if the food is high or low in salt!
  • For those who do have more time, be careful when reading food labels and check the amount of salt ‘per serving’ not per 100g as some may be displayed
  • Don’t be fooled by ‘special’ salts which claim to be better for us such as Himalayan salt – salt is salt!

How to eat for Brain Health

Leave a comment
We all want a healthy, functioning brain for as along as possible. How we eat and drink really does impact it.
 
Studies on cognitive function and brain health show that overall a wholefood plant-based diet with a limited intake of animal and high saturated fat foods is the way forward. A big piece of research on this is call the MIND diet. Researchers at Rush University Medical Center in Chicago created the MIND diet –  this identified food groups and nutrients from the Mediterranean diet and the DASH diet that had been linked to lower risk of dementia.  Over 900 older men and women’s diets were analyzed and  people who stuck closely to a MIND diet were 53% less likely to be diagnosed with Alzheimer’s over the 4.5-year study period, compared with people who adhered least to the diet.
 
10 brain healthy foods identified by the MIND diet:
Green leafy vegetables
Vegetables
Nuts
Berries
Beans/lentils/soybeans
Wholegrains
Seafood
Poultry
Olive Oil
Wine (in moderation).
 
5 foods identified to not be good for brain health by the MIND diet:
Red meat
Butter and margarine
Cheese
Pastries and sweets
Fried or fast food
 
See you can see that a brain healthy diet really does go along the lines of a Mediterranean diet and general healthy eating. Other research on 447 adults showed that they performed better in cognitive tests after four years on a Mediterranean diet compare to a control diet.
 
​Here is my meal plan published in the Daily Mail as part of Twinstitute for BBC2.
 
Let’s dig a bit deeper….there are some specific nutrients that have been highlighted as improving cognitive function.
 
B vitamins and folate :  shown to have a link to improved cognitive function, possibly by decreasing homocysteine levels. The evidence is not robust but suggestive. For example a study on elderly people with an increased risk of dementia showed that high doses of B vitamins slight brain shrinkage over 2 yrs.
Specifically looking at vitamin B12, cohort studies have suggested that dementia rates are highest in those with a lower B12 status.
 
Omega 3’s: the brain comprises 60% fat and is one of the fattest organs in the body. With such a high percentage of fat in the brain it’s no surprise that fatty acid’s are important nutrient. Specifically we need to know which fatty acids are important. The research we have suggests that it is the omega three fatty acid‘s to focus on. These have the potential to slow cognitive decline. Fit to focus on therefore our fish, shellfish, algae and the plant foods walnuts, linseeds and chia seeds.
 
Antioxidants including Vits A,C and E: Oxidative stress is one of the primary reasons are brain function declines. Therefore antioxidants are of upmost importance. This brings us back to the good old fruit and vegetables once again proving that we just need to be eating more of them. There has been some research looking specifically at berries and berry juice linking this to increasing memory scores, also the famous avocado for its vitamin E content. Similarly flavonoids found in red wine, dark chocolate, green tea can also help fight oxidative stress. There are some small scale, low power studies that look at blueberries, green tea and red wine that suggest these can be helpful. We have some limited research suggesting that nut intake (specifically walnuts) is associated with better brain function. This fits in with the Mediterranean diet, they contain antioxidants including vitamin E and so it makes sense.
 
Water: about 75% of the brain is made up of water therefore dehydration even in small amounts can have a big affect. Therefore staying hydrated is key.
 
So top foods to eat more of?
Oily fish
Green tea
Plenty of fruit and veggies
Green veggies
Colourful berries
Nuts, seeds including walnuts
Avocado
Wholegrains
Drink water
 
And then a little of the red wine plus dark choc makes a perfect combination.

Back to school lunches

1 Comment
Back to School. It’s that time again. My girl loves having packed lunch is and actually I quite like knowing what she’s having. But it can become repetitive, so one of our aims is to get inspiration and vary each of the food groups. We always go for a carbohydrate option, some protein, raw veggies and fruit as the basics. Then we add in a few extras such a yoghurt, a muesli bar or some cake. Of course one of the biggest factors is what your child actually likes! It’s no good giving them beautiful looking nutritious food if the won’t eat it.
 
I’d love to say that we spend time each weekend baking for lunches or that we whip up spectacular salads each week. Truth be told, packed lunches are made quickly after dinner whilst I tidy up the kitchen, usually before I teach Pilates and while the kids run around the house like crazies. It’s doesn’t have to be complicated, but balance and variety are 2 of the keys 🔑.
 
Carbohydrates: Bagels, wraps, pitta, bread, baguette, crackers, rice, pasta, couscous.
 
Protein: tuna, cheese, ham, salami, peanut butter, cottage cheese, cream cheese, eggs, turkey, chicken, hummus.
 
Raw veggies: cucumber, 1/2 avocado (with a spoon), tomatoes, peppers, carrots, gherkins, olives, sweet corn, peas, mange tout, sugar snap peas, mushrooms.
 
Fruit: melon, apple, berries, satsumas, pear, grapes.
 
Extras: malt loaf, yoghurt, cheese portion, popcorn, cheesy biscuits, cereal bar, dried fruit bar, homemade flapjack.
 
 
 
 
 
Sandwich Filling Ideas:
Cheese and pickle 
Hummus and ham 
Egg and hummus
Salami and cream cheese
Avocado and cream cheese
Avocado and egg salad
Tuna and mayo
Mashed chickpeas, avocado and mayo
Peanut butter
Nut butter and banana
Cheese and marmite
 
Alternatives to Sandwiches:
Sushi (make a batch and use it for 3 days)
Pasta, rice or couscous  salads
Pizza Whirls – use your choice of toppings
Picky Box – crackers, cheese, veggies and let them make their own lunch at school
 
I’d love to hear your ideas! I share packed lunches regularly on my inst-stories so do give me a follow.

Should I eat more plant based diet?

Leave a comment

What are the benefits?

Plant based diets (PBD’s) are better for the environment and provide a more sustainable way of eating. There are also health benefits due to eating more plants altering the nutritional profile of your body. 

PBD’s tend to be lower in saturated fat due to less meat. They usually contain higher amounts of fruit and vegetables which means higher fibre content for digestive health (those bowels) and a greater range of antioxidant plus phytochemicals. 

The inclusion of wholegrains provides B vitamins and fibre, beans/pulses for soluble fibre and these help with blood sugar control, soy products provide phytoestrogens that can be helpful in the menopause plus nuts and and seeds that are packed with antioxidants and micronutrients.

Some specific health benefits:

Research shows us that PBDs can lead to lower levels of total and low-density lipoprotein (LDL) cholesterol levels. This is going to reduce the risk of cardiovascular disease.

 Also improvements can be seen in serum glucose levels which helps in overall health and in type 2 diabetes control. 

There has been shown to be a lower level of overall inflammation in the body. These factors combines are thought to contribute to a reduced risk of chronic diseases. 

Does this mean we should all go vegetarian/vegan? Well not necessarily. What I do think it means is that having a greater emphasis on eating plants sources of food is helpful and healthful. As with all ways of eating there are many ways to do it, so the benefits you see on paper will depend on how you actually approach this way of life. This in my mind is about adding in plant foods more than taking things away. 

Will I be missing out nutrients?

It is perfectly possible to meet your nutritional needs on a PBD. However you will need to be more intentional about it. Planning and being thoughtful about some key nutrients plus a couple of supplements will ensure you get all your body needs.

Protein : It can be easier to get protein from animal sources. However this doesn’t mean we shouldn’t be eating plant proteins! Most people in the UK are exceeding their protein needs, especially with the focus on protein in so many snack foods right now.  When calorie needs are met it is more than possible to meet your protein requirements on a PBD. However it is a good idea to vary your protein sources through the week so that cover all those essential amino acids the body needs.

  • Mycoprotein, soya protein and pea protein 
  • Beans and lentils
  • Nuts and seeds 
  • Tofu
  • Eggs and dairy (if these are eaten)

Iron : The recommended daily amount of iron for vegetarians is 1.8 times higher that for non-vegetarians, as iron which comes from plant sources (non-haem iron) is less efficiently utilised in our body than iron which comes from animal sources. Eat iron rich foods daily and all should be well. 

  • Iron fortified breakfast cereals
  • Beans
  • Nuts and seeds 
  • Wholegrains 
  • Dried fruit 
  • Green leafy vegetables 
  • Yeast extract 
  • Eggs, fish and poultry (if these are eaten)

Calcium: one of my hobby horses, as I like to look after my bones. Calcium can be lower on a plant based diet but there are plant foods that will help those bones stay strong. Check your plant based milk is supplemented and get on those leafy greens. Some studies show a lower bone mineral density in those not eating dairy, so this is definitely a nutrient to think about. 

  • Fortified dairy alternatives (like: soya or nut milks and yoghurts)
  • Fortified juice drinks
  • Green leafy vegetables
  • Dried fruit
  • Tofu
  • Beans, lentils and chickpeas
  • Nuts and seeds
  • Bread

Vitamin B12: as this is mainly found in animal products it is one of the nutrients you may end up lacking. It is found in yeast extract and most multivitamins/minerals.

Omega 3 : mainly talked about as being in oily fish but also found in seaweed, linseeds and walnuts. If you know you won’t take in many of these foods you could take a supplement.

  • Seaweed (not recommended more than once per week) 
  • Chia seeds, linseeds/flaxseeds, hemp seeds 
  • Rapeseed oil
  • Walnuts and walnut oil
  • Soybeans and soybean oil
  • Tofu
  • Spreads and breads which are fortified with omega 3
  • Oily fish (if this are eaten)
  • Eggs and dairy which are fortified with omega 3 (if these are eaten)

Iodine: highlighted in some studies as a nutrient that can be low on a PBD, but also on a meat eaters diet too!

  • Iodised salt
  • A limited amount of fortified dairy alternatives (e.g. specific brands of oat milk) 
  • Seaweed (but this is not recommended more than once per week) 
  • Dairy products and seafood (if these are eaten)

Selenium: mainly found in Brazil nuts so not necessarily a problem on  PBD but a good one to be aware of.

  • Brazil nuts 
  • Eggs and fish (if these are eaten)

Nitrates, nitrites and eating sausages.

1 Comment

There has been so much talk about red meat over the last few years. The guidelines from the WHO told us not to eat too much red meat and showed the link between red meat and colorectal cancer. This risk was higher with processed red meat. Today it’s been more news about processed meat causing cancer, so as a population we are still eating our bacon it seems.

The problem this time is nitrates (NO3) and nitrites (NO2). These are often added to processed meats as they help it keep its pink colour and are important in food safety – protecting against botulism. Nitrates are metabolised to nitrites in the body, these are all fine until they combine with protein to form Nitrosamines. These can be carcinogenic. There lies the problem.

However nitrates themselves can be beneficial, they can relax blood vessels, being beneficial for blood pressure. They can improve the blood flow to muscles in exercise and they are a cofactor for reactions in the body.

Nitrates are found in processed meats such as bacon, ham, salami and chorizo. Interestingly they don’t seem to be added into UK made sausages, which is a slight win. They are also found added into higher amounts in smoked fish, cured fish and beer (especially German beer). The levels in your piece of ham are small. Nitrates are also found in vegetables however these naturally occuring forms do not appear to react in the body in the same way as those added into meats.

The take home – eating less meat is a good thing for the planet and for our bodies, but there is no need to cut it out entirely. In my opinion cutting things out is generally not a helpful approach. Processed meat is not something to be eating daily but it is ok to eat it occasionally. You can find some processed meats now that are nitrate free, check the labels nitrate/nitrites, but remember that does not mean you can eat it regularly. As a population we all should be eating less meat and more plant based proteins when we can. So keep that bacon sandwich for a now and again brekkie.

The benefits of Green Tea

2 Comments
Green tea is made by the rapid steaming of freshly harvested leaves which stops the process of oxidation to black tea.
 
Green and black tea contain similar levels of total flavonoids but the difference in oxidation means there are differing types of flavanoids. Black tea has higher levels of theaflavins and thearubigins and green tea has 3.5 x the catechins levels. The main catechin in green tea is Epigallocatchin-3-gallate (EPCG).
 
Brewing time, the method to make your tea and the tea quality are all things that influence antioxidant status. Tea polyphenols are effective antioxidants and scavengers of free radicals. Studies show an increases in antioxidant levels in humans after drinking green tea. This is what is likely to provide any health benefits.
 
 
There is a misconception that green tea is caffeine free like a herbal tea. It is lower in caffeine but still contains some. Up to 400mg of caffeine a day is considered safe. That’s 8 cups of green tea! It may not be as hydrating as water but it does still provide hydration.
 
Black Tea : 40-70mg caffeine per cup
Coffee: 80-115mg caffeine per cup
Green Tea: 25mg caffine per cup
 
Most studies on tea are observational, are conducted on animals or in Asia where there is a different diet. Therefore it is an area we need clearer studies and research results.
 
Heart disease
Flavanoids in green tea has been shown to lower LDL cholesterol levels and decrease blood clotting. A meta-analysis of 13 research trials showed a decrease in systolic and diastolic blood pressure, total and LDL cholesterol, blood Triglyceride (fat) levels and overall stroke risks. So it does sound like there are benefits for your heart.
 
Weight loss
This is a an area that had a lot of interest. There is some mixed evidence here suggested green tea may stimulate thermogenesis and increase fat oxidation. This means you burn more calories when you digest your food and you use up more fat stores. Sounds good but the results were modest and so this won’t give you large weight loss. It’s certainly no magic cure but switching from a soft drink to green tea daily will reduce your calorie intake.
 
Cancer
There are very mixed results in the research so over there is no clear proof either way. Green tea is certainly packed with antioxidants so it could help and it won’t hinder.
 
Osteoporosis
Animal studies and studies on post menopausal women shows an association between tea consumption and better bone health due to the tea polyphenols. We have some emerging evidence for green tea improving muscle strength and bone health. An exciting area to focus on.
 
Brain Health
There is some research showing a link between green tea and brain health with it improving memory and brain power. Could be worth a green tea cuppa in the mornings.
 
 
Over all we need more studies to give us further information but it does seem that green tea is a good choice for your cuppa.

Menopause and Diet.

Leave a comment

The menopause is a time of life that can be distressing and cause symptoms that affect the quality of life significantly. However it is also a time of life that we neglect to talk about which makes it harder for women to know the evidence for treatments and where to get support. 

When does the menopause occur?

The average age is 51yrs, but there is a wide range. The menopause is defined as 12 months after your last menstrual period.  Women can be in the peri-menopausal stage where hormone levels are changing and symptoms are occuring for 4-5 years before the menopause occurs.

Symptoms can include hot flushes, night sweats, mood swings, disrupted sleep, brain fog, poor concentration, vaginal dryness and joint pains. For some these are mild and for others these are severe causing day to day life to be altered and upsetting. 

There are many supplements, pills and potions around that are said to help with the symptoms of the menopause. Sadly a lot of these have no real evidence behind them and end up being very expensive. Nutrition is something that plays a pivotal role in our health so it will come as no suprise that there are dietary changes that can be made to help offer some relief. There are also health issues that need ot be considered with the menopause approaching, which are covered below. 

Hot flushes:

These are one of the most common symptoms and one reason why HRT is recommended. Other lifestyle changes that can help incllude reducing the intake of alcohol, spicy food and caffeine. Weight loss can also help, a study has shown an improvement of 30% with 5kg weight loss.

Countries that eat more soya foods seem to have a lower incidence of hot flushes. This is thought to be due to the phytoestogens. Research suggests 2 x 200ml glasses of soya milk a day of 80g soya mince will give you this benefit. 

Bone Health

Bone loss is escalated in the menopause, so calcium is slowly lost from the bones. this is due to osteoclast cells that breakdown bone work harder than osteoblasts (cells that build bone). The recommended daily amount of calcium in the UK is 700mg/d if there is no risk of osteoporosis. However many women reach the menopause with low bone mineral density, in which case they will need to be having more like 1000-1200mg/d. Therefore it is important to focus on increasing calcium rich foods. Good examples include dairy, fortified plant milks, sesame seeds, dried figs, watercress and fortified bread. Weight bearing exercise will also help with bone health.

A note of caution is that excess vitamin A is associated with an increased risk of osteoporosis, so post-menopausal women should not exceed 600 micrograms a day. 

Heart Health:

Levels of total cholesterol can rise after the menopause whilst levels of HDL cholesterol tend to fall. This can, combined with weight gain and falling oestrogen (oestrogen is cardio-protective) can be a risk for heart health. 

Weight gain:

Metabolic rate slows down by about 10% after the menopause, this is why central weight gain can occur. Therefore staying active and eating a balanced diet is key. Resistance training using your body weight or light weights is a good alternative to high impact workouts. 

Top Tips:

  1. Reduce saturated fats and eat more polyunsaturated and monounsaturated fats, for example more nuts, avocado, olive oil and seeds. 
  2. Soluble fibre is good for heart health and cholesterol levels. Godo foods include oats, barley, nuts, seeds, beans, lentils, peas.
  3. Incorporate more soy based foods into your diet. Soya milk, yoghurt, soy mince and tofu.
  4. Ensure you are eating calcium containing foods – dairy, plant based fortified milks, green leafy veggies, tofu and tinned fish with bones. Also take a vitamin D supplement.
  5. Keep active and include weight bearing exercise in your week.
