What to Look For in Foods to Boost Your Immune System
Health advice should be practical and sustainable, not extreme. These are the factors that decide whether a habit actually sticks and delivers results.

- Evidence behind it: approaches supported by research rather than fads or quick-fix promises
- Fit with your routine: how easily it slots into your schedule, energy, and lifestyle
- Safety: appropriate for your fitness level and any existing conditions
- Enjoyment: if you genuinely like it, you will keep doing it, which is what really counts

How We Ranked Them
We chose foods with genuine nutritional backing for overall health, prioritising ones that are easy to find, affordable, and simple to work into everyday meals rather than exotic superfoods.
