Apple

Apples are good at regulating metabolism; they contain antioxidants and improve the immune system's strength. Apples are great for regulating digestive microflora, helping control blood sugar levels, and protecting the cardiovascular system.

Apples contain vitamin C, most other vitamins (B1, B2, B3, B5, B6, B9, B12, A and retinol, E and tocopherol, D, F, β-carotene, lycopene) and minerals, a large number of vegetable fibers, quercetin and pectin.
