Why your ‘5 A Day’ might be holding back your health
If you've been hitting your five a day and still wondering why you don't feel better, you're asking exactly the right question.
5 A Day was never designed to optimise your health. It was a global public health floor, set to address micronutrient deficiency and then the food industry got hold of it. Most UK adults aren’t even reaching it and the evidence now points to double that number as the level at which meaningful reductions in disease risk actually start to show up.
In this article, I break down where the guidance really came from, what a large-scale study of over two million people tells us about how much we actually need and why diversity of plant foods may matter just as much as quantity, particularly if you're navigating fatigue, persistent symptoms or an immune system that isn't behaving itself. Plus practical ways to close the gap without overhauling your entire life.
