Peanut, almond, fine nut consumption beneficial against metabolic syndrome
Eating a relatively small amount of peanut, almond and pine nut may protect against the risk of developing metabolic syndrome (MetS), and the benefit differs by sex and age, a study from Korea has found.
The study population comprised 2,684 men (mean age, 50.9 years) and 2,622 women (mean age, 50.3 years) who were grouped according to their peanut, almond and fine nut intake (<1 serving/month, 1/month–0.5/week, 0.5–1/week, and ≥1/week; one serving corresponds to 15 g) and followed for up to 10 years.
More than half of the men (55.7 percent) and two-thirds of the women (69.3 percent) consumed peanuts, pine nuts and almonds less than once a month, with only 11.9 percent and 8.6 percent reporting having more than one serving per week, respectively. The average consumption was 6.6 g/week in men and 5.1 g/week in women.
Multivariable Cox proportional hazard analysis revealed a significant inverse association between consumption of peanut, pine nut and almond and the incidence of MetS. Furthermore, there was a clear dose-response pattern, with the greatest protective benefit seen among men and women in the highest intake category.
In men, the hazard ratios (HRs; vs <1/month intake category) were 0.91 (95 percent CI, 0.76–1.09) in the 1/month–0.5/week, 1.03 (0.80–1.31) in the 0.5–1/week and 0.72 (0.56–0.93) in the ≥1/week intake category. The corresponding HRs in women were 0.81 (0.65–1.003), 0.76 (0.54–1.07) and 0.57 (0.41–0.79).
Subgroup analysis showed that the protective benefit of peanut, pine nut and almond intake against MetS risk varied by sex and age and was more pronounced in middle-aged men eating ≥1 serving/week and in old-aged women consuming ≥0.5 serving/week.
