Effect of the consumption of amaranth seeds and their sprouts on alterations of lipids and glucose metabolism in mice

Amaranth (Amaranthus hypochondriacus) is appreciated for its nutritional and functional quality. This study evaluated the effects of consuming amaranth seeds and their sprouts on the metabolic markers in ICR male mice. Ungerminated amaranth seeds (A) and one-day (G1) and three-day (G3) germinated amaranth sprouts were dried and milled. The mice groups (n = 10) were fed standard (N) or hypercaloric (H) diets and 1 g A, G1 or G3/kg body weight for 28 days. The total cholesterol (TC), high- and low-density lipoprotein (HDL and LDL), atherogenic index (AI), triglyceride (TG) and glucose levels were determined in blood samples. Germination increased the dietary fibre, phenolic and flavonoid concentration and decreased ash and squalene concentration. A, G1 or G3 consumption also decreased body weight, TC, LDL, AI and glucose levels in H group mice. Thus, amaranth seed or sprout consumption could be beneficial for people with altered lipid metabolism.
