Our immune systems get a real workout at this time of year with cold, flu’, and tummy bug germs thriving in warm, dry, centrally heated homes and offices. It’s a good idea to top up on immune-supporting nutrients to give your system the best chance of fending off these invaders as much as possible.
Here are 4 simple ways to nourish your immune system this winter…
Need more? Try these too:
– Vitamin C has powerful anti-viral action, particularly against the flu’ viruses. Food sources include watercress, peppers, kiwi, berries, peas, parsley, broccoli, and lemons. If you’re at high risk of infection consider using at least 1000mg per day of ascorbic acid or Ester-C.
– Zinc may help to reduce the severity and shorten the duration of colds. Food sources include poultry (chicken soup really can work wonders), pumpkin seeds, red meat, and cashew nuts. Zinc citrate lozenges are a quick way to boost levels and helpful at the first tingles of a cold.
– Echinacea has a long history of traditional use for respiratory infections like colds and flu’. Go for an organic whole herb extract that contains the natural balance of active compounds; A.Vogel do tinctures, tablets and a throat spray in their excellent ‘Echinaforce‘ range. It’s a winter staple in my remedy cupboard!

Done properly, a plant-based diet can provide nearly all the nutrients we need to thrive. Done badly, a vegan diet is the same as any other poor diet.
As a nutritionist I come across all kinds of diets. Vegan, juice fasts, raw food, keto, Paleo, Hay (not chewing on actual hay…although someone will probably make a ton of money from the idea one day) – and people ask my opinion of them.
When it comes to veganism, I think it’s fine so long as it’s done properly and involves real food. I have several vegan colleagues, including the brilliant nutritionist Elena Holmes, who epitomises the healthy vegan lifestyle.
However, a vegan diet is not;
– The answer to our environmental and food sustainability issues
– The cure for every known health issue
– Easy to follow. This is especially true if you dislike vegetables and pulses – and there are plenty of vegans who don’t like vegetables. Good luck with that.
There are certain nutrients that a wholly plant-based diet cannot easily provide and you may need to consider supplementation to side-step any deficiencies. Remember that some deficiencies can take months, even years to present with full on symptoms. Vitamin B12 is a good example of this. You may have good bodily stores of B12 when you begin a vegan diet, and these stores can keep you going for several months. Gradually, they start to drop and that’s when you’ll notice symptoms like tiredness, brain fog, and poor memory.
The most bioavailable form of B12 is unique to animal products. It plays an important role in mental wellbeing, heart health, nerve cells, and red blood cell function.
Top sources include shellfish, lamb, and beef (there’s an interesting list on Nutrition Data: it’s a US site, hence the inclusion of moose meat – not a common source for those of us in the UK!).
Many foods suitable for vegans are fortified with B12; nutritional yeast and breakfast cereals for example. Certain plant foods do naturally contain B12, the most notable being the sea vegetables green and purple nori. Studies have shown that eating these forms of nori can improve B12 status, though you would need to eat substantial amounts every day to support levels in the long term. Same goes for shiitake mushrooms. Of all the edible mushrooms, shiitake carries good levels of B12 but you would still need to eat an average of 50g (dried weight) per day to maintain levels. That’s a whole lot of mushrooms. To be on the safe side, include these foods regularly and consider using a B12 supplement if you plan to be wholly plant-based for more than a few months.
Spirulina and other edible cyanobacterias (commonly called blue-green algaes) contain pseudovitamin B12 which isn’t bioavailable to us as humans. We can’t absorb it or use it so please don’t be fooled by advertisements claiming otherwise.
Iron – haem and non-haem
Iron deficiency is a particular issue for female vegans due to regular iron loss from periods. Haem iron in animal products is much better at being absorbed than non-haem iron from plant sources. If you are relying on non-haem iron, be sure to include sources of vitamin C too, as this helps the absorption and usage of plant-sourced iron.
Good combinations include;
– Millet grain (iron) in a salad with vit-C-rich-foods like watercress, parsley, and peppers
– Blackstrap molasses (iron) in hot water with a good squeeze of fresh lemon juice (vit C)
– Pumpkin & sunflower seeds (iron) in a fruit salad with papaya, kiwi, and strawberries (all good sources of vit C)
Many of us, whether vegan or not, are low in vitamin D simply because we don’t get enough regular sunshine here in the UK. Unfortunately for vegans, the optimum dietary sources of vitamin D3 (the most active usable form) are eggs, liver and butter, with plant sources like mushrooms providing a little D2.
It is advisable for everyone to take a supplement during winter months (October to April) and vegans may need to continue all year round. To check your levels, see your GP or try a home test kit from www.vitamindtest.org.uk
Vegetarian and vegan diets tend to have plenty of omega-6, but often struggle with omega-3. Nuts and seeds provide what is known as the ‘parent’ omega 3 fat, Alpha Linoleic Acid (ALA). This needs to go through several conversion steps before it becomes EPA and DHA (eicosapentaenoic acid and docosahexaenoic acid). These are the omega-3 fats we use for brain and heart health, and which are ready formed in fish oils.
These conversion steps rely on co-factor nutrients like magnesium, B-vitamins, zinc, and vitamin C, and a lot of ALA gets lost during the process. There isn’t an easy answer to this dilemma, other than to ensure vegans include walnuts, flaxseed oil, and/or pumpkinseed oil everyday for their rich ALA content, and to enjoy plenty of food sources of the co-factor nutrients too;
– Magnesium: almonds, cashews, hazelnuts, dark green leafy vegetables
– Zinc: nuts & seeds
– B-vitamins: widely spread throughout the plant kingdom; sweet potatoes, brown rice, avocadoes, nuts, seeds, and dark green leafy veggies are especially useful
– Vit C: watercress, peppers, broccoli, berries, kiwi, papaya, peas

Getting plenty of the ‘sunshine vitamin’ has never been so important! In fact, a recent study highlighted the fact that 1 in 3 people globally is vitamin D deficient – and Europeans are more at risk than North Americans! We manufacture Vitamin D in our skin from the suns rays yet most of us now spend our days indoors and slather on the suncream when out in the sun so we never really get chance to make it.
The surge of research in recent years has shown how Vitamin D plays crucial roles in
– bone health; osteoporosis, rickets
– heart health; high blood pressure, heart attacks, stroke
The old UK RDA levels of 400iu per day are currently being reviewed and new, much higher levels considered. As Dr Janyne Althaus discusses, this is particularly important for pregnant Mums as the baby’s demand for vit D increases greatly in the later months of pregnancy when bone formation is taking place yet Mum is at risk of deficiency if her own Vitamin D stores are too low.
Now that we have passed the Autumn Equinox and the days are getting gradually shorter, the suns rays are no longer strong enough to give us the UVB rays needed for the manufacture of vitamin D in our skin. Supplementing with it throughout winter is therefore a sensible and safe option – if you don’t like swallowing capsules or pills, try one of the new vitamin D sprays that are available and take at least 1000iu per day.
