Hi,
I think our bodies function best (and that includes the immune system) when we have a good, nutritious diet. There are many different ways to get a nutritious diet, from vegan to carnivore, since it mainly depends on quality fresh ingredients, cooked appropriately, and eaten in the right proportions.
I also think that most ppl believe that the way they eat is ‘healthy’, yet if they actually analysed what they are eating (variety, amount processed, nutritional content, how much their body actually absorbs…) they would be shocked. There is usually a great deal of room for improvement!
So, in answer to your question, you can look at your personal situation, and your current health levels and do some research.
there is a free app (+ a paid for option) called Cronometer
Eat smarter and live better. Cronometer is your personalized nutrition app to track macronutrients and micronutrients and count calories.
cronometer.com
that you can use to enter everything you eat and drink.
it will then analyse the nutritional content of what you eat (For 84 nutrients)
That is excellent for identifying any glaring deficiencies.
You can also do a bit of reading around the gut biome and ways to feed/foster a healthy gut biome. I am currently adjusting my own way of eating to include certain amounts of soluble and insoluble fibre, pre and pro biotics, and specific foods to cultivate my gut biome. Only 3 weeks in, and I am frankly astonished at the changes I‘m experiencing.
I’m expecting these changes to have a huge benefit to my immune system, and I’ve always been a firm believer in specific, tailored, good quality supplement programme using natural food sourced nutrients.
- and I think that mass produced, cheap, generic multi vit n mins (the kind you get in a supermarket) are a waste of time and money.
