Nutrition ( aliment ) is the provision, to cells and organisms, of the materials necessary, in the form of food (in the case of people) to support life. Good nutrition depends on a regular and balanced diet, because we need to feed our cells not only the quantities but also the right variety for its healthy function. The most famous Food Guidance is the Food Pyramid.
1.Common food groups
A food group is a collection of foods that share similar nutritional properties or biological classifications. Nutrition guides typically divide foods into food groups and recommend daily servings of each group for a healthy diet. Fats and oils, sometimes categorized with sweets, is typically a very small category in nutrition guides, if present at all, and is sometimes listed apart from other food groups. Examples include cooking oil, butter, margarine and shortening. Sweets, also called sugary foods and sometimes categorized with fats and oils, is typically a very small category in nutrition guides, if present at all, and is sometimes listed apart from other food groups. Examples include candy, soft drinks, cake, pie and ice cream. Dairy, also called milk products and sometimes categorized with milk alternatives or meat, is typically a smaller category in nutrition guides. Examples of dairy products include milk, yogurt and cheese. Though they are also dairy products, ice cream is typically categorized with sweets and butter is typically classified with fats and oils in nutrition guides. Meat, sometimes labeled protein and occasionally inclusive of legumes, eggs, meat analogues and/or dairy, is typically a medium- to smaller-sized category in nutrition guides.Examples include chicken, fish, turkey, pork and beef. Fruit, sometimes categorized with vegetables, is typically a medium-sized category in nutrition guides, though occasionally a small one. Examples include apples, oranges, bananas, berries and melons. Vegetables, sometimes categorized with fruit and occasionally inclusive of legumes, is typically a large category second only to grains, or sometimes equal to grains, in nutrition guides. Examples include spinach, carrots, onions, peppers, and broccoli. Grains, also called cereals and sometimes inclusive of potatoes and other starches, is often the largest category in nutrition guides. Examples include wheat, rice, oats, barley, bread and pasta. Water is treated in very different ways by different food guides. Some exclude the category, others list it separately from other food groups, and yet others make it the center or foundation of the guide. Water is sometimes categorized with tea, fruit juice, vegetable juice and even soup, and is typically recommended in plentiful amounts.
A poor diet can have an injurious impact on health, causing deficiency diseases such as scurvy and kwashiorkor; health-threatening conditions like obesity and metabolic syndrome; and such common chronic systemic diseases as cardiovascular disease and diabetes. 2. Uncommon food groups
