In nutrition, the diet is usually the sum total of the food ingested by an organism or individual throughout the day. It refers to the foods that an individual eats for the maintenance and growth of the body. Some of the most important nutrients needed by the body are carbohydrates, protein, and fats. Some people need to control their diet depending on their age, sex, and some other factors.
The amount of carbohydrates consumed determines the amount of food energy available in the body. Therefore, the amount of carbohydrates consumed is directly related to the amount of food energy available in the body. A high carbohydrate diet can provide more energy than a low carbohydrate diet. The main source of carbohydrates in the diet are food energy derived from carbohydrate-rich food like meat, bread, pasta, rice, and so on.
A diet low in fat can be defined as low in fat but high in carbohydrates. Usually, a diet low in fat pertains to a vegetarian diet. A diet low in sugar involves mostly fruits and vegetables rather than whole grains and other food energy rich food.
Obesity is a major problem today because many people do not pay attention to their dietary intake. These people believe that any dietary intake can promote weight gain. This is a misconception because the amount of carbohydrates and other nutrients required by the body depends on the dietary intake. Some studies have proved that dietary intake can change the production of appetite hormones. This means that if an individual ingests more calories than he or she should, the body will respond by storing more fat in the cells instead of burning it to fuel the body’s activities.
A balanced diet should contain all the nutrients necessary for good health. The foods that should be included in the diet include the necessary vitamins and minerals, which are not always available in the everyday meals. Carbohydrates should be the major part of the diet. They provide energy for the body to function properly. Fruits and vegetables are a great source of these nutrients.
Some people think that a low-fat diet can help them lose weight but this is not true because a low-fat diet also contains some carbohydrate. The diet should contain a balance between the two because excess carbohydrate leads to obesity. Low-fat diets usually promote weight gain because they reduce the intake of fats and carbohydrates. This is not a good strategy because a balanced diet must contain the right amount of both the carbohydrate and the nutrient to ensure weight loss and promotion of good health.
