Understanding the Food Guide Pyramid

The terms of nutrition, food, diet, food culture, food chain, and human diet are all related to the study of eating habits and eating patterns and how these patterns may relate to human health and wellbeing. In the United States the food guide pyramid provides the most comprehensive guide to healthy diets and is widely used by school children, parents, and caretakers to help them create a nutritious and balanced food diet. The pyramid has been developed by a group of scientists who recognized the wide variety of dietary needs and foods based on different cultures and lifestyles. The food guide pyramid shows how much daily nutrient intake each nutrient from the different food groups should provide to maintain a typical healthy weight and how these nutrient levels vary with the food type.

Nutrition refers to the process of converting food into nutrients in the body. Nutrition is also the process by which energy is gained from food through metabolism and the process by which the body uses energy. Food is any material taken from the environment, to provide nutrition to the organisms. Food is generally of animal, plant or fungi origin, and includes necessary nutrients, including carbohydrates, fats, vitamins, minerals, or proteins. The body needs various kinds of food for different physiological processes and growth; some food is necessary for maintenance and growth but others are converted into other substances that are not necessary.

One of the problems with the food guide pyramid is that it can be confusing because on the one hand it provides a list of foods that are required by the body to meet its nutrition requirements and on the other hand it lists foods that are considered to be fat and cholesterol because they contain high levels of calories. The problem is that it is not known what percentage of the food you eat is fat and what percentage of the food contains vitamins and minerals that are actually beneficial to the body. Some nutritionists believe that we should limit our consumption of fat and cholesterol foods and eliminate or reduce the consumption of processed and packaged foods that are loaded with preservatives, colorings, artificial flavors, added sugar and other unnecessary fillers. They also believe that some foods such as processed meat, dairy products and eggs are actually fat and cholesterol.
