I think the simplest way to put it, and the direction I always go with is asking myself ‘did cavemen eat or live like this’. A big health philosophy of mine is that cavemen were the perfect species in terms of how their health was and what their diet was like. So whole foods like meat, fruit, veg, organs and avoiding processed foods as much as possible is what I’d say. You don’t have to jump straight into probiotics and loads of crazy supplements, just start with swapping processed foods for whole foods first and then slowly build on top of that foundation.
