Eating for a healthy gut

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
leeks Tempeh
Cocoa Kimchi
Flaxseeds Miso
Artichoke  Kombucha
Barley Live yoghurt

What is Orthorexia Nervosa and what can I do?

Leave a comment

Orthorexia Nervosa is the newest eating disorder phrase on the block. It was devised by Steven Bratman in 1996, after he noticed a trend in his patients. Ortho means rich or correct.

Orthorexia = an unhealthy obsession with healthy eating. It can have elements of anxiety disorders and OCD with it.

Orthorexia Nervosa

Whilst there is an overlap here with anorexia nervosa and people with orthorexia may end up developing anorexia, there is also a big difference. Orthorexia is taking healthy eating to the extreme, it has an aspirational, wellness culture ideal associated with it. This means it is less about weight and more about purity and an ideal lifestyle. Social media has certainly heightened this and fuelled it. With role models who life perfect pure lifestyles of food, exercise and spirituality, it can seem as if that ideal is achievable and realistic. Striving to achieve it leads to feelings of failure and guilt.

The Bratman Orthorexia Self-Test

This is a test devised by Steven Bratman to help identify if you are at risk of orthorexia. If you answer YES to ANY of these questions you may be at risk.  I think it is useful test to read through and think to how much you identify with the statements.

(1) I spend so much of my life thinking about, choosing and preparing healthy food that it interferes with other dimensions of my life, such as love, creativity, family, friendship, work and school.

(2) When I eat any food I regard to be unhealthy, I feel anxious, guilty, impure, unclean and/or defiled; even to be near such foods disturbs me, and I feel judgmental of others who eat such foods.

(3) My personal sense of peace, happiness, joy, safety and self-esteem is excessively dependent on the purity and rightness of what I eat.

(4) Sometimes I would like to relax my self-imposed “good food” rules for a special occasion, such as a wedding or a meal with family or friends, but I find that I cannot. (Note: If you have a medical condition in which it is unsafe for you to make ANY exception to your diet, then this item does not apply.)

(5) Over time, I have steadily eliminated more foods and expanded my list of food rules in an attempt to maintain or enhance health benefits; sometimes, I may take an existing food theory and add to it with beliefs of my own.

(6) Following my theory of healthy eating has caused me to lose more weight than most people would say is good for me, or has caused other signs of malnutrition such as hair loss, loss of menstruation or skin problems.

If you identify with anything in this post then I highly recommend that you reach out to your medical team, GP, a friend, a parent, a dietitian who works in this field like myself. You can also contact B-Eat.

Top tips for Orthorexia:

Here are some steps you can take to help combat Orthorexia, I suggest these are done with the support of a therapist and dietitian.

  1. Unfollow anyone on social media who fuels the thoughts of having to eat a pure diet/lifestyle. Or try a social media detox for a week.
  2. Focus on eating a variety diet. There are no wrong or right foods it is all about the balance and variety that you eat. Nothing is off limits. Nothing is wrong to eat. 
  3. Work with someone qualified in this area to redefine healthy for you. This may include food, movement, quiet space, social time, family time.
  4. Develop alternative coping skills. Can you see how food helps you feel in control and also makes you anxious? Using distraction after a meal and journalling your thoughts can be a good initial step.
  5. Write out a list of your food rules/beliefs. These need to be challenged.
  6. Only allow yourself to get your nutrition knowledge from someone with a minimum of a degree in nutrition  –  a registered nutritionist or dietitian.
  7. Stop tracking your nutrition. This may take time to do so start with doing it at one meal at a time.

Should I count calories?

Leave a comment
With all these calorie counting apps that are around and the pressure is better on us to look a certain way calorie counting can be an easy trap to fall into. Whilst it can be useful in some clinical instances I don’t think it is helpful for the general purposes of dieting.
 
Formally, a Calorie is a measure of the amount of energy required to heat one kilogram of water one degree Celsius. It was first used in engineering and physics, but eventually found its way into nutrition, we have Wilbur Atwater to thank for that.
 
Whilst it may make sense that tracking your calories, macros and nutritional intake will help you with your weight, overall health or dietary intake in fact it can have the opposite affect. It can lead to you becoming obsessed with counting everything you eat and feeling you have to stick within a certain number of calories per day. This will stop you enjoying your food and impact your socialising too.  What if you are out with friends in a cafe, a once a week occurance and the cake you is 450kcals plus a coffee 150kcals but you are only allowing yourself to eat 1500kcals a day? That cake is 1/5th of your calorie intake for the day, so is it worth eating it? Do you choose to eat it knowing you will be over your calorie limit for the day but that you have enjoyed your cake and time with friends, do you choose to eat the coffee and cake but then restrict your calories the next day to make up for it or do you decline the cake and feel deprived and as if you cannot join in?
 
Dietitian UK: Why I don't like calorie counting
 
I’d suggest that calorie counting can be a useful guide and tool for one off occasions but over the long term it has the potential to become obsessive.  Following a calorie restrictive diet does not make it a balanced diet. You could be getting all your calories from just fruit and veggies or be skipping a whole food group out.
 
There is also the question of is it even accurate? There is no way to accurately know the exact calories of the food apart from using a calorimeter in a laboratory. I don’t know about you but I don’t want to burn my food up each time! Yes this is worked out for us on food labels but that is a guide. A slightly different portion size, a different way of cooking, a slight change to a recipe and it will have a small affect. Does that matter? No not really as the calories are just a guide. 
 
Delving deeper,  your body will also not necessarily absorb all the calories that you eat. For some foods such as nuts for example, a proportion of the calories are excreted. So even know you may be eating  X  amount of calories you are not necessarily going to be absorbing all of those. Other foods can make your metabolism work harder, again showing calorie counting to not be a 100% accurate tool.
 
Personally I do not think counting calories on a daily basis is helpful and it can be a negative trap that you fall into. Instead look at the balance of your diet. Think about getting a range of nutrients in to your day and a wide variety of foodstuffs. Ensure you cook from scratch as much as possible, eating wholegrains and starchy foods, fruit and veggies, protein and healthy fats regularly. Enjoy what you eat, stop when you are full, eat when you’re hungry and be mindful of the food that you consume but not consumed by it.

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)

Photo by rawpixel on Unsplash

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)

Improve your Diet for 2019

Leave a comment
 
Whilst diets are flying everywhere and detoxes around every corner here is how to make long-term change your diet that will give you lasting health benefits for life.
 
How are you eat impacts your gut health and your long-term risk of diseases. So here are my top 5 food goals, which I’m taking onboard for myself too.
 
 
Increase your fruit and vegetable consumption by one portion.
It may not seem like much but if you manage to do this every day then it’s going to make a long-term change over the year.
 
Plan your meals.
Plan out what you’re going to eat incorporating a variety of foods across the week. Different colour vegetables for the different antioxidants and phytochemicals. Different grains, different protein sources (e.g chicken one day, red meat another, fish and lentils other times.
 
Eat more gut friendly foods.
This can be simply more fibre from whole grains and fruit/veggies and more probiotics from live yoghurt, sourdough bread, pickles or kefir.
 
Go plantbased where possible
Note this this does not mean you need to go vegan. Incorporating plantbased proteins is going to be an ever increasing trend. It’s definitely one to follow. Plant based meals are better in terms of sustainability and environmental impact plus they deliver a range of nutrients you may not get through a meat meal. More on this to come in my next blog posts.
 
Cook from scratch more.
This doesn’t have to mean every day but go for it if you can! Everyone is busy so try planning in times when you can bulk cook and stocking up the freezer. Cooking from scratch doesn’t have to be complicated or take that much time. I will be posting regular recipes on my social media to show what we eat. Trust me, I don’t have hours to cook.
 
However you start your new year try and keep your goals simple, achievable and remember that food is to be enjoyed!

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:
