In order to stay alive, we need the right kind of food and nutrition. Nutrition is the supply of food materials that are necessary for humans to stay alive. Nutritional science is all about breaking down food and repairing cells and tissues in our body. Nutritional studies also focus on the diseases and ailments of the body and how they can be treated with good nutritious food. People should be well aware of the amount of nutrition intake that is expected of them in a day. This will help them stay healthy. A human body requires seven types of nutrients. In order for our body to work well, we need both macro as well as micronutrients. Macronutrients are what our body needs in large quantities while micronutrients are required only in small quantities. Our body needs 4 kcal per gram carbohydrates a day.
These consist of mostly carbon, hydrogen and oxygen atoms. Malnourishments will lead to many diseases including heart diseases. We are what we eat, and so always give importance to healthy foods. Avoid eating junk food as much as you can. Water is yet another important nutrient that our body needs. Our body is basically 70 percent water and hence replenishing lost water from the body is extremely important for a healthy life. The amount of water that is needed for our body depends on a variety of factors that includes our age, size, gender, jog, physical temperature, environment temperatures and even the kind of food we eat. This means, a person consuming more salt would require greater amounts of water. Rigorous physical activities and an increased environmental temperature will require you to drink plenty of water. If there is not much water content in your body, you will be dehydrated. Hence body fluids should always be maintained at the right levels. Deinking excess water will not lead to any side effects; they are just dispersed from the body in the form of urine and sweat.
Moreover, drinking more water will help you look beautiful and supple. It makes your skin glow better. Minerals are what our body needs next. Minerals like potassium, chloride, sodium, calcium, zinc and iron are extremely important for the smooth functioning of body. A deficiency in minerals will cause diseases in our body. For example the deficiency of iron in our body leads to anemia. This is a situation where the body blood levels are less than what is required. In such cases physicians would advise the intake of iron supplements. Anemia will result in a person looking pale. It will also lead to dizziness and fatigue. Apart from the nutrients that are required by the body, the body also needs a supply of essential vitamins. Vitamins can be divided into water soluble and fat soluble. All the necessary vitamins and nutrients that you need come mainly from the food you eat. Others are naturally produced in the body. However maintaining the right levels of nutrients and vitamins is the key to lead a better and healthy life.
