Fatso Diet Guidelines
There are numerous types of fat. Your body makes its own fat from taking in excess calories. Some fats are found in foods from plants and animals and are known as dietary fat. Dietary fat is one of the three macronutrients, along with protein and carbohydrates, that provide energy for your body. Fat is essential to your health because it supports a number of your body's functions. Some vitamins, for instance, must have fat to dissolve and nourish your body.
The Dietary Guidelines are jointly issued and updated every 5 years by the Departments of Agriculture (USDA) and Health and Human Services (HHS). They provide authoritative advice for Americans ages 2 and older about consuming fewer calories, making informed food choices, and being physically active to attain and maintain a healthy weight, reduce risk of chronic disease, and promote overall health.
The Dietary Guidelines describe a healthy diet as one that
Emphasizes fruits, vegetables, whole grains, and fat-free or low-fat milk and milk products;
Includes lean meats, poultry, fish, beans, eggs, and nuts; and
Is low in saturated fats, trans fats, cholesterol, salt (sodium), and added sugars.
Carbohydrates are a type of nutrient found in many foods and beverages. Carbohydrates are your body's main energy source. Most carbohydrates are naturally occurring in plant-based foods. Food manufacturers also add carbohydrates to processed foods as starches or added sugar. Carbohydrates in the form of sugars, starches and fiber are found in legumes, grains, vegetables, fruits, milk, baked goods and many other foods.
Protein is an important nutrient, essential for growth and development. All the cells of your body include protein. Protein is also an important source of calories and energy. Both plant-based and animal-based foods provide protein.
Fats aren't necessarily bad for you, but you need only a small amount. Dietary fat is a nutrient that helps your body absorb essential vitamins, maintains the structure and function of cell membranes, and helps keep your immune system working. Some types of fat, though, may increase your risk of heart disease and other health problems. Fat also has a lot of calories, increasing the risk of weight gain.
