Almonds

Prunus dulcis

Also known as Sweet almond

The edible seed of a stone fruit closely related to the peach, eaten raw, roasted or ground into flour and butter. The USDA reference entry is for the raw kernel.

Potential health benefits

Best supported: Insufficient

Ordered by how well the human research supports them — strongest first. A rating describes the state of the evidence, not how impressive the food is. How we rate evidence.

Some trials report lower post-meal glucose when almonds are eaten with a carbohydrate meal, and small improvements in HbA1c in people with type 2 diabetes, though results across trials are mixed.

Insufficient evidence. Not enough human research to say anything useful yet.

No source is attached to this association yet, so it is rated insufficient by default. It is listed because people commonly ask about it — not because there is evidence for it.

Blood lipid profile

Heart Health
Insufficient evidence

Research consistently shows that adding almonds to the diet lowers LDL and total cholesterol, with multiple meta-analyses of controlled feeding trials pointing the same way. The effect is modest and depends partly on what the almonds replace.

What may be going on: Substituting the monounsaturated fat and fibre of almonds for saturated fat and refined carbohydrate lowers LDL, with a small additional contribution from phytosterols and reduced fat absorption.

Satiety and appetite

Weight Management
Insufficient evidence

Several trials report that almonds increase fullness and that adding them to the diet produces less weight gain than their calorie content would predict, partly because some fat is not absorbed from intact nuts.

Skin structure and hydration

Skin Health
Insufficient evidence

There is not enough dependable human research behind almond and skin-wrinkle claims. The few trials are small, short and mostly funded by the industry that markets the product.

Nutrient values are per 100 g of the USDA reference entry named on this page and vary with variety, growing conditions, storage and preparation.

Source record: Nuts, almonds (USDA FoodData Central, FDC ID 170567).

% DV uses the FDA Daily Values for adults and children aged 4 and over. A dash means no Daily Value has been established for that nutrient.

Bioactive compounds

Compounds present in meaningful amounts. Presence is banded rather than quantified, because whole-food levels vary enormously with variety, growing conditions, storage and preparation.

How preparation changes things

Only effects with real support are listed. If a preparation method is missing, it is because nothing dependable is documented — not because it makes no difference.

  • roastedChanges lipid oxidation and skin polyphenols

    Roasting improves flavour and shelf stability at moderate temperatures but accelerates oxidation of the unsaturated fat at high temperatures or long times. Blanching before roasting removes the skin and with it most of the polyphenols.

  • soakedReduces phytate

    Soaking almonds softens them and modestly lowers phytate; the frequently repeated claim of a large nutritional change from overnight soaking is not well supported.

Things to know

Allergies, interactions and intake concerns. Every food gets this section — a reference where everything is uniformly good is not a reference.

  • Allergy

    Tree nut allergy

    Almond is a tree nut and one of the major regulated allergens. Reactions can be severe and rapid, including anaphylaxis, and people allergic to one tree nut are often advised to avoid others because of cross-reactivity and shared processing lines.

  • Worth knowing

    Oxalates and kidney stones

    Almonds are among the highest-oxalate nuts. For people who form calcium oxalate kidney stones, large daily amounts of almonds or almond flour are a genuine consideration, and clinicians often advise moderating them alongside adequate fluid and calcium intake.

  • Worth knowing

    Phytate and mineral absorption

    Almond phytate binds iron and zinc within the same meal. Soaking reduces it somewhat, though less than in grains and legumes because almond phytase activity is low.

  • Worth knowing

    Energy density and portions

    Almonds are energy dense, and portions are easy to misjudge from a bag. Trials suggest whole nuts release less of their energy than the label implies because intact cell walls resist digestion, but that does not make the portion irrelevant.
