Nut
Food · Protein · Food, Typed Supps
Almost all of them are high in fat — but chestnuts are starchy, and peanuts are not really nuts at all.
Stage by stage
- Intake (Chewing fractures cell walls): Chewing breaks the cell walls holding the fat; how finely depends on the nut and the form.
- Digestion (Slow gastric emptying): High fat, protein and a rigid matrix slow stomach emptying and prolong fullness.
- Absorption (Fat and minerals taken up): Lipid is absorbed with vitamin E and magnesium; whole nuts release less of it than ground forms.
- Circulation (Lipid profile shifts): Unsaturated fat displacing saturated fat is the main route to the observed cholesterol effect.
Time to effect
- Weeks: Cholesterol effects appear over roughly 4 to 8 weeks of daily intake, not from a single serving.
Allergens
None of the fourteen major allergens. Derived from what this food is, not from a product label.
Eating patterns
Fits: Halal, Kosher, Gluten-free. Depends on the product: Vegan, Vegetarian, Pescatarian, Keto, Low-FODMAP.
Satiety
79 on the satiety index, where white bread is 100 — low. Modelled from the Holt et al. (1995) measurements.
Cost band
Mid — roughly £11 per kg, as a band midpoint rather than a price.

Food vs. supplement
A vitamin E capsule delivers alpha-tocopherol alone; 30g of almonds or almond meal supplies a similar order of magnitude alongside magnesium, fibre, protein and monounsaturated fat. Trials of isolated vitamin E supplements for heart disease have been consistently disappointing, while whole-nut intake has held up — a reasonable illustration that the matrix, not the single nutrient, is doing the work.
Kitchen tip
Roasting changes flavour, not the fat profile in any meaningful way — the difference between a raw and a roasted cashew on the label is mostly moisture loss, plus whatever oil and salt the roaster added. Read for 'roasted with oil, salted' if either matters to you. Store the high-polyunsaturated ones, walnut especially, in the fridge; they go rancid faster than almonds.
Common myth
"Nuts are too fattening to eat regularly." In reality: Regular nut eaters do not tend to gain weight in cohort or trial data. They are highly satiating, and a portion of the fat in whole nuts is never absorbed at all because it stays trapped behind intact cell walls.
