In the last year, with Covid-19, there’s probably never been a more important time to invest in your health. With this in mind, I’ve put together a mini guide  to help you keep yourself and your loved ones safe, not just through Covid but for general wellbeing.

Despite advances in medicine and science, nutritional and lifestyle interventions  are still one of the most powerful ways to build and boost your immune system. There is now a wealth of research out there confirming this. 

With this in mind, my aim at Lucy Childerley Clinic, is to make you as resilient as you can be, by optimising your health naturally.  

Your immune system is constantly being challenged all day, every day, dealing with your environment, food, chemicals, stress, etc  but what you eat and drink can really help support your body..

It’s so important to eat the most nutrient rich, WHOLEFOOD diet that you can within your likes and budget. Whole, unprocessed, foods in their natural form, not only give you everything you need in terms of nutrients, they are also free from all the things you don’t want in your body, such as processed chemicals, toxins and substances that stress your body and give it more work to do, diverting it from keeping you in tip top condition!

7 Ways to boost Your Immunity Naturally Through Diet


1. Protein– This is vital macronutrient  for the immune system. Protein malnutrition is actually linked to higher death rates from infection. It increases your susceptibility  to infectious diseases and, once infected, it increases the severity and  duration of the disease. Good sources of protein include meat, fish, poultry, game, pulses, nuts, legumes, dairy.

2. Low GL carbohydrates– Low GL means low glycaemic load (GL). This refers to how much a food will raise your blood sugar levels after eating it. White, refined foods will have a much higher GL than wholegrain and this puts more pressure on the body to deal with the excess sugar. Refined products have also have their natural vitamins, minerals and fibre stripped from them which leaves them being void of much nutrition. This combined with  very little fibre, also leaves you feeling hungry soon after eating, which could encourage overeating.  Good sources of slow burning carbohydrates include, short grain brown rice, brown rice pasta, wild rice, sweet potatoes, oats and all vegetables.

3. Good fats– every cell in the body is made from fat so you need to support at this cellular level as much as possible. Fat helps you store vitamin D which is considered protective against Covid-19. Healthy fats include oily fish, avocado, nuts and seeds

4. Phytonutrients– Eat the rainbow! These are nutrients found in plants that actually protect the plants and improve their resilience to toxins, radiation, pests and chemicals. The beauty is that when you eat them, you too enjoy these benefits. Phytonutrients are ant- oxidants which help protect you from free radical damage which can damage your DNA , suppress your immunity and stop your body from functioning efficiently.  To ensure you get all of the main phytonutrients you need, eat the rainbow by making your plate as colourful as possible, with as many phytonutrients as possible.

Meet the phytonutrients

  • Carotenoids found in your orange, red and yellow fruits and veggies, such as carrots, bell peppers, oranges.
  • Glucosinolates which are mostly in the brassica vegetables, Brussels, kale, cabbage, cauliflower, broccoli.
  • Phytoestrogens– can mimic oestrogen so can be great to balance hormones but they also boost your immune system. Food sources include organic soy products, flaxseed, nuts, legumes, broccoli, carrots, oranges, beans, whole-grains.
  • Ellagic acid– Found in berries, including raspberries, blackberries, cranberries, strawberries, pomegranates and walnuts. 
  • Flavonoids in nearly all veggies and fruit, including apples, berries, onions, grapefruit, cabbage, kale, leeks, tomatoes, ginger, lemons, carrots, buckwheat, dark chocolate  (YAY!), tea. 

5. Probiotics– Interestingly  scientists believe that the gut microbiome may influence your immune system response to Covid19 infection and may affect the severity and outcome.  They have also found that there are distinct characteristics in the gut microbiome once the infection has been cleared, leading them to speculate that this may be contributing to the symptoms of  the dreaded long Covid. It is very early days but could be a fantastic step towards an effective treatment plan for these patients.

When you consider that  80% of your immune cells are in your gut, it makes sense to really support this area. Dysbiosis is the  imbalance of bacteria in the gastrointestinal tract and signs to look for include bloating, gas, wind, cramps, constipation, heartburn, acid reflux, poor sleep, skin irritation, food intolerances, autoimmune conditions. These can be diagnosed through a simple stool test which I can arrange for you but you can also help build a stronger gut microbiome by introducing probiotic foods such as fermented foods like live yoghurt,  kefir, sauerkraut as well as pre biotic foods such as onions, garlic, leeks, chicory, resistant starch (cooked and cooled potatoes, rice and pasta). You can also supplement with a range of pre and pro-biotics, just check  they are good quality and include lots of diversity. I recommend excellent broad spectrum supplements to help support your gut microbiome health. 

6. Extra  super immunity foods to boost your system include:

  • shiitake mushrooms and oats which contain beta glucans to help support the white blood cells and fight infection.
  • garlic, onions and ginger all have anti microbials in them to fight nasty microbes
  • spices such as  turmeric, oregano, thyme, rosemary are all anti-inflammatory.

7. Water– Dehydration is on the main stressors to the body. Water helps the body carry oxygen to our cells for optimal functioning. It also helps remove toxins, preventing them building up in the body and having a negative impact on your immune system.


We all know them but here they are in black and white!! Processed foods, white starchy foods, excess caffeine and alcohol. These all put pressure on the body which causes inflammation and suppressing the immunity.

 I use the 80/20 rules. with my clients. 80% of the time good, then 20% let go! This way you never feel deprived  which makes it much easier to stay on track!

9 Supplements to support the immune system

Much as your food is the ideal way to get your vitamins and minerals, sometimes, with today’s busy lifestyle it can be a struggle to get the amount your body actually needs. This is where supplements can come in useful. As the name suggests, they are there to supplement, not replace, your diet.  

If you would like more information on specific supplements to you, get in touch. I offer client discounts on all supplements.

1. Vitamin Dis vital to your immune system and overall body function. There have now been many studies conducted on the benefits of taking  vitamin D to protect from Covid 19. Finally, last year, the government  announced guidelines, recommending 400iu which, when you consider that 20 minutes sun exposure gives us 10-20,000 iu, is simply not enough. It is thought that 90% of people in the UK are vitamin D deficient during winter months which could explain SAD and increased infections at this time of year. You can get your vitamin D tested for £29 at to see where your levels are then you can accurately supplement vitamin D3.I recommend taking Vitamin D3 with vitamin K2 for the best outcome all round.

2. Vitamin C  is fantastic for the immune system, supporting various cellular functions of the innate and adaptive immune system. Vitamin C protects cells from pathogens and uses its anti-oxidant properties to potentially protect against environmental oxidative stress. A deficiency results in impaired immunity and a higher susceptibility to infections. Supplementation with vitamin C appears to be able to both prevent and treat respiratory and systemic infections (Carr and Maggini, 2017).  These can be found in a good multi or taken separately  as a time release supplement to allow for maximum absorption. 

3. Vitamin E is also an anti-oxidant. It has not seen many human studies but animal studies have highlighted a clear link between vitamin E deficiency and immune system impairment. Some studies have shown a positive correlation between optimal vitamin E levels and reduced risk of developing flu. 

4. Vitamin B12 and folic acid  studies have shown that  a deficiency in these vitamins can interfere with body processes, causing inflammation. 

5. Zinc helps  maintain homeostasis of the immune system and a deficiency impacts both innate and adaptive immunity. 

6. Seleniumis very important anti-oxidant and a good quality multi vitamin should contain sufficient levels.  Alternatively eating a 3-5 Brazil nuts a day will fulfil your daily selenium requirement.

7. Magnesium is a vital nutrient involved in many processes in the body, especially your hormones! yet many people have low levels. Magnesium is important to help relieve stress and calm you down which helps protect the immune system. It’s also a fantastic sleep enhancer and energy booster. It can be found in a good multi or taken separately. An all round superhero.

8. Omega 3’s are essential fatty acids that are important to relieve inflammation, protect cells and improve your general health. Make sure to get one with good levels of EPA and DHA. I absolutely LOVE the Nutriadvanced Eskimo-3 one as it’s the only one I’ve found that does not repeat throughout the day! It is also one of the most researched and written about in the world- a fantastic pure, toxin free, sustainable product.  

9. Adaptogenic herbs stimulate the immune system indirectly, by building the body’s resistance to non-specific stresses, such as poor diet, environmental toxins, overwork and  emotional factors. They also stimulate the immune system by boosting resistance to pathogens, viruses and bacteria. Some useful immunity boosting adaptogenic herbs include:

  • Andrographis
  • Echinacea
  • Astragalus
  • Siberian Ginseng
  • Ashwagenda

Always check with your doctor before taking any supplements if you are on any medication.

Other things that can have a negative impact on the immune system include:

  1. Poor digestion which may prevent you from absorbing sufficient nutrients.
  2. Dysbiosis- poor gut bacteria preventing absorption.
  3. Food sensitivities- causing inflammation
  4. Aging- sadly makes you more susceptible to immune dysregulation

4 Lifestyle Interventions

1. Stress- Good old stress! Well if you weren’t a stressed person before 2020, I can imagine you are now! Stress takes a huge toll on the body with cortisol suppressing and weakening the immune function over time. You need, therefore, to factor in some down time EVERY DAY. I have to really work on this as do many other people I know, feeling guilty about spending time on myself, but now may be the perfect time to re-evaluate and make new habits!

Start with just 5 minutes a day of deep breathing. There are loads of apps that do square breathing and other styles. I started adding it in to the end of my Pilates classes and now it’s become the highlight of the class! It really does work, helping reset the body, switch the stress side off and the calm side on.  If you want to invest longer there are great meditation apps such as calm and headspace which offer a range of calming programmes from 10 minutes onwards.

2. Good sleep is also paramount. When you sleep our cells renew  and repair and you release cytokines to fight infections and inflammation. Humans needs between 7-9 hours of  good quality sleep a night and anything less has been proven to detrimentally affect the immune system. Many sleep deprivation studies have shown a rise in inflammation.  There are many ways to improve sleep which include getting morning daylight every day, dimming lights at night and removing devices from the bedroom. If your struggle with sleep I can help get you back on track.

3. Movement helps boost the immune system and relieves stress. Whether it’s an online class, a walk, run, or strength training, it all helps to protect your body. Out in nature is best and doing with someone else (either a friend or PT) has been shown to improve compliance!

4. More than ever it’s so important to stay connected to others. Many studies have shown that having positive social support can enhance your resilience to stress, improve your self confidence, increase your happiness and improve your overall health and longevity!  A good old laugh with friends and family can also be really helpful to pull you out of your funk and lift your spirits.
