2. Effects of taking an excess of food nutrients.

The nutritious substance does good only in optimum amount. If we take more amount of nutrient, there is an excess of that nutrient. Sometimes it leads to ill-effects. For example, if we eat a high quantity of fat, there is a higher chance of getting obesity. Some water-soluble vitamins do not cause any harm as they move out of the body through water. But fat soluble vitamin-like Vitamin A, D, E, K accumulate inside the body.
