What are the healthiest foods to eat for longevity, metabolic health, and disease prevention? In this video, I break down the 15 healthiest foods I eat every week as a doctor, based on nearly a decade working in emergency medicine and the strongest available research on nutrition, ageing, cardiovascular disease, and long-term health.
After years treating heart attacks, strokes, type 2 diabetes, and preventable chronic disease, I’ve seen first hand how diet shapes how we age — not through supplements or superfoods, but through boring, repeatable, single-ingredient foods eaten consistently over decades. This video explains why these foods matter, how they work in the body, and how they reduce long-term risk.
I’m Dr Alex, a UK Emergency Medicine doctor, and this channel focuses on evidence-based longevity, metabolic health, and disease prevention — the advice most doctors don’t have time to explain in clinic. If your goal is to live longer, stay independent, and avoid the diseases I see every day in A&E, this video will give you a practical framework that actually sticks.
I also reveal one of the most harmful everyday foods that quietly makes up a huge proportion of modern diets — and why its cumulative effects matter more than people realise.

It’s called The Long Game, and it’s an extension of everything I do here on the channel. Every morning I’ll send you something short, whether that’s a thought I’ve had that day, a tip you can put into practice, a piece of research I found interesting, or something I’ve learned from years of seeing people at their worst in A&E.
Most take between thirty seconds and a couple of minutes to read, so it fits around a normal morning, certainly shorter than my videos anyway…
I’ve called it The Long Game because that’s what all of this is. There are no shortcuts and no quick fixes in anything I teach. It’s small things done consistently over many years, and that’s what genuinely changes your health in the end.
It’s free, and you can sign up here: https://www.dralexnewsletter.com
This is brand new, and so the first few emails may end up in your spam, as with all new email newsletters, but hopefully this will soon sort itself out….
Let me know what you think!

Chickpeas and shrooms cooked together are the perfect combination..
You are quite an excellent teacher. I really appreciate the information you are sharing so well
I’m good with pretty much all these, while a little surprised that oatmeal didn’t make the (steel-) cut.
Claude speaks too much, well know problem.
