Macronutrient Breakdown — per 100g
23 almonds = 1oz = 28g = 164 kcal. Net carbs: 9.1g/100g. ~10-15% of almond fat is not absorbed due to intact cell walls. Effective calories are ~490-515 kcal/100g.
Micronutrient Highlights
Almond Health Benefits
Vitamin E — Richest Common Source
Almonds provide 25.6mg of vitamin E per 100g (171% DV) — the richest common dietary source. One oz covers 37% of the daily requirement. Vitamin E is the primary fat-soluble antioxidant protecting cell membranes from oxidative damage. Adequate vitamin E is associated with reduced cardiovascular disease risk and improved immune function. Most people consume less than 50% of recommended vitamin E.
Magnesium — Most Dense Common Food
Almonds provide 270mg of magnesium per 100g (64% DV) — the highest magnesium density of any commonly consumed food. One oz provides 76mg (18% DV). Deficiency affects ~50% of adults and is associated with insulin resistance, hypertension, and poor sleep. Regular almond consumption is one of the most effective dietary interventions for magnesium status.
Cardiovascular Protection
A 1993 NEJM study found almond-enriched diets significantly reduced LDL cholesterol. Multiple RCTs confirm: 1.5oz almonds daily reduces LDL by 5-10mg/dL. Mechanisms include oleic acid replacing saturated fat, plant sterols inhibiting cholesterol absorption, fiber binding bile acids, and vitamin E preventing LDL oxidation.
Fat Absorption — The 20% Discount
Research in AJCN found 10-15% of almond fat is not absorbed due to intact cell walls. Effective calorie content is ~490-510 kcal/100g rather than 579. This partially explains why almond consumption in studies does not lead to expected weight gain.
