Human health is closely related to a healthy diet. A poor diet can cause or influence the short-term and long-term problems in our body. The human body needs a balanced and varied diet. The main nutritions that our body needs are proteins, carbohydrates and fats. In order to ensure good health they are supposed to be used in certain proportions. A healthy diet requires not only these substances, but also vitamins and minerals that are acquired through food or supplements.
The recommended daily allowance (RDA) - the vitamins and minerals per day, which is enough to almost every healthy human body. However, not all of these materials or not all the required amount can be ingested, so if you like to stay healthy, they must be obtained from various other sources, such as food supplements.
