It is obvious that good nutrition and regular exercise help you stay healthy. Everything what you eat and drink affects how your body functions. Your nutritional needs depend on how you live your life as well. The connection between diet and health is clear: to grow properly and function normally, you need a complete range of nutrients, including carbohydrates, proteins, fats, fibre, water and variety of minerals and vitamins.
Nutrient are essential for body functioning and, if they are in balance, they can improve your state of health and protect you against a number of diseases. Eating healthy makes you feel well, which improves your mood and enables you to deal better with stress.
If your diet lacks any nutrients or provides too much of certain factors, your body will not function at an optimum level. At the same time, you may be creating potential problems. For instance, there are strong facts that eating too much animal fat can lead to cardiovascular disease, while skipping calcium-rich food in your teens may lead to osteoporosis later.
To maintain a healthy weight, you need to balance energy you expend during the day. Nowadays we don’t get as much exercise as we need. Excess food intake is stored in the body as fat, leading to weight gain and possibly to obesity. This also can lead to various medical conditions, such as diabetes, cardiovascular disease, cancer, and joint problems.
If we expend more energy than we take in, we will lose weight. But being underweight brings its own health problems and a reduced life expectancy.
