The almond contains about 26% carbohydrates (12% dietary fiber, 6.3% sugars, 0.7% starch and the rest miscellaneous carbohydrates), and may therefore be made into flour for cakes and cookies (biscuits) for low-carbohydrate diets. A standard serving of almond flour, 1 cup, contains 20 grams of carbohydrates, of which 10 g is dietary fiber, for a net of 10 g of carbohydrate per cup. This makes almond flour very desirable for use in cake and bread recipes by people on carbohydrate-restricted diets.
Almonds are a rich source of vitamin E, containing 26 mg per 100 g (Table). About 20 percent of raw almond is high quality protein, a third of which are essential amino acids.[citation needed] They are also rich in dietary fiber, B vitamins, essential minerals and monounsaturated fat (see nutrient table), one of the two fats which potentially may lower LDL cholesterol. Typical of nuts and seeds, almonds also contain phytosterols, associated with cholesterol-lowering properties.
Potential health benefits, which have not been scientifically validated, include improved complexion and possibly a lower risk of cancer. Preliminary research associates consumption of almonds with elevating blood levels of high density lipoproteins and lowering low density lipoproteins. A preliminary trial showed that, in spite of the high fat content of almonds, using them in the daily diet might lower several factors associated with heart disease, including cholesterol and blood lipids.
Almonds contain polyphenols in their skins consisting in a combination of flavonols, flavan-3-ols, hydroxybenzoic acids and flavanones analogous to those of certain fruits and vegetables.
Almonds may cause allergy or intolerance. Cross-reactivity is common with peach allergens (lipid transfer proteins) and tree nut allergens. Symptoms range from local symptoms (e.g., oral allergy syndrome, contact urticaria) to systemic symptoms including anaphylaxis (e.g., urticaria, angioedema, gastrointestinal and respiratory symptoms).
Almonds are a rich source of oil, with values ranging between 36 to 60% of kernel dry mass.[39][40] A study by Venkatchalam and Sathe suggests almonds contain approximately 44% oils, of which 62% is monounsaturated oleic acid (an omega-9 fatty acid), 29% is linoleic acid (a polyunsaturated omega-6 essential fatty acid), and 9% is saturated fatty acid.
“Oleum Amygdalae”, the fixed oil, is prepared from either sweet or bitter almonds and is a glyceryl oleate, with a slight odour and a nutty taste. It is almost insoluble in alcohol but readily soluble in chloroform or ether. Sweet almond oil is obtained from the dried kernel of sweet almonds.
The oil is good for application to the skin as an emollient, and has been traditionally used by massage therapists to lubricate the skin during a massage session.
Almond oil can also be used as a wood conditioner of certain woodwind instruments, such as the oboe and clarinet.
