The disease diet built.
Heart disease kills more people worldwide than any other condition, and it is almost entirely a disease of lifestyle. Plant-based diets are the only diets that have been shown — in randomised trials with imaging — to halt and reverse atherosclerosis. The evidence is among the strongest in nutrition science.
EPIC-Oxford found vegetarians had 32% lower risk of heart disease than meat-eaters; vegans had the lowest risk of all. Adventist Health Study-2 found vegan men had 55% lower risk of dying from heart disease. The Lifestyle Heart Trial (Ornish, 1990, Lancet) and the Esselstyn cardiology series both showed atherosclerosis regression on whole-food plant-based diets with no added oil — the only diets in the literature with this result.
Red and processed meat (saturated fat, haem iron, carnitine→TMAO pathway), full-fat dairy (saturated fat, IGF-1), eggs (cholesterol, choline→TMAO), and added oils and refined carbohydrates (endothelial dysfunction, oxidation). Removing the first three and limiting the fourth is the basis of every successful trial diet.
Vegetables (especially leafy greens, for nitrates and folate), whole grains (oats, barley, brown rice — fibre and beta-glucan), legumes (soluble fibre, plant protein, magnesium), nuts and seeds (unsaturated fat, vitamin E, arginine). Berries, garlic and dark chocolate (≥85%) each have small additional benefits.
"The Ornish and Esselstyn trials remain the only diets in the published literature shown to reverse heart disease without surgery."
Build meals around the four protective groups. Use herbs and spices instead of salt. Use lemon, vinegar, mustard or tahini for dressings; minimise added oil if you have established disease. Eat a handful of nuts daily. Eat oats most mornings. Have a leafy-green portion most days. Cook beans or lentils regularly. Walking 30 minutes a day amplifies every benefit.
Oatmeal with berries, walnuts, ground flax and soya milk.
Big lentil-vegetable soup with sourdough; an apple and a few almonds.
Chickpea curry, brown rice, steamed broccoli with lemon and garlic; small square of dark chocolate.
30-minute walk; one strength session three times a week.
7–8 hours. Sleep deprivation independently raises cardiovascular risk.

Yes, in trials. Ornish and Esselstyn both demonstrated arterial regression with whole-food plant-based diets. Not everyone reverses, but many do, especially earlier in the disease.
Continue them. Add the dietary change. Many people are able to reduce medication over time with their cardiologist.
Better than a standard Western diet; not as good for reversal as a whole-food plant-based diet. The most cardio-protective Mediterranean variants are heavy on vegetables, beans and olive oil and light on meat and cheese — closer to vegan than to typical.
Coconut oil raises LDL the same way butter does. Limit it even on a vegan diet.
Of every chronic-disease change you can make today, this is the one with the strongest trial evidence. Eat, walk, sleep, retest.
