Minimize Ultra-Processed Foods
Keep ultra-processed food under 10 to 20 percent of intake. The single biggest dietary lever most people haven't pulled.
What it does
Ultra-processed foods are the dietary pattern most consistently associated with elevated mortality in recent meta-analytic work. The association is large enough and the downside small enough that minimizing intake is a higher-confidence move. Cooking at home is the simplest version.
UPF tends to be calorie-dense, low in fiber and protein, high in refined carbohydrates and industrial fats, and engineered for hyperpalatability — a combination that drives overconsumption and adverse metabolic effects beyond what individual macronutrients predict.
What the evidence shows
Overall evidence strength: Moderate certainty
Who it's for, who should skip
Anyone eating substantial packaged food. Keep UPF under ~10–20% of intake; the category that matters is industrial hyperpalatable formulations — soda, snacks, packaged baked goods — not plain yogurt or frozen vegetables.
