Choose Healthy Fats

Cook with olive oil and snack on nuts and seeds instead of relying on saturated-fat-heavy options.

Evidence suggests…

Emphasizing unsaturated fats (olive oil, nuts, seeds, fish) is associated with favorable lipid and cardiovascular markers, and olive oil intake tracks with better cardiovascular outcomes. We grade this B because the saturated-fat side of the debate remains genuinely contested in the literature.

How to do it

Use olive oil as your main cooking fat; add a small handful of nuts/seeds most days

This is the evidence-based dose. A shorter session still counts, it just gives partial benefit rather than the full effect.

Common misconceptions

'All fat is fattening and bad.' Fat type and overall pattern matter more than total fat.
'Nuts make you gain weight.' Modest portions fit weight management and aid satiety.
'Coconut oil is a health food.' It is high in saturated fat; olive oil has better evidence.

What we won't claim

Do not claim any food, diet, or supplement cures, treats, or prevents any disease
Do not diagnose nutrient deficiencies or medical conditions
Do not promise specific weight-loss amounts or timelines
Do not deliver individualized medical nutrition therapy or replace clinical care

When to seek a professional

Signs of disordered eating (food/weight preoccupation, restriction, bingeing, purging, compulsive exercise) -> qualified eating-disorder professional
Diagnosed medical condition (diabetes, chronic kidney disease, heart failure, GI disease) -> registered dietitian or physician
Pregnancy or breastfeeding -> prenatal provider or registered dietitian
Unintentional weight loss, difficulty swallowing, or persistent GI symptoms -> medical evaluation
