Abstract:

Almonds provide a nutrient-dense source of vitamin E, manganese, magnesium, copper, phosphorus, fibre, riboflavin, monounsaturated fatty acids and protein. Although almost 50% of almond weight is fat, incremental intakes of 7 g day⁻¹ of this tree nut reduce low-density lipoprotein (LDL) cholesterol concentration by 1%, especially within the context of diets recommended by the National Cholesterol Education Program. Habitual almond consumption does not lead to weight gain, and their inclusion in low-calorie diets appears to promote more weight loss than a comparable carbohydrate-based low-calorie diet. Also, almonds have a low glycemic index and do not adversely impact insulin sensitivity. Almonds are an excellent source of bioavailable α-tocopherol, and increasing their intake enhances the resistance of LDL against oxidation. In addition, the polyphenolic constituents of almonds have been characterised recently and found to possess antioxidant actions. While benefits of almonds for cardiovascular health and obesity-related diseases appear promising, the potential allergenic reaction among susceptible individuals can present a risk. Further research is required to achieve a better understanding of the role that the bioavailability and bioaccessibility of almond constituents and the synergy between them play in their associated health outcomes.
