Study Notes
Major Food Groups
- There are five major food groups: grains, dairy products, fruits, vegetables, and protein-rich foods
- Each group provides key nutrients and has specific serving sizes
- Dietary guides recommend choosing whole grains, minimally processed foods, and a variety of foods from each group
Grains
- Include products made from wheat, rice, and oats
- Examples: pasta, noodles, flour tortillas, bread, cereal
- Serving size: 1 slice of bread, 1 cup of ready-to-eat cereal, or ½ cup of cooked rice, pasta, or cereal
- Whole grains contain more fiber and nutrients than refined grains
- Refined grain products can be enriched or fortified with vitamins and minerals
Dairy Products
- Include milk and products made from milk that retain calcium content
- Examples: yogurt, hard cheeses, milk-based desserts (e.g. ice cream, pudding)
- Serving size: 1 cup of milk or equivalent (e.g. 1 cup of plain, low-fat yogurt or frozen yogurt)
- Dairy products are excellent sources of protein, phosphorus, and riboflavin
- Choose fat-free or low-fat milk and dairy products
Protein-Rich Foods
- Include beef, pork, lamb, fish, shellfish, poultry, beans, eggs, nuts, and seeds
- Serving size: 1 ounce of meat, poultry, or fish; ¼ cup cooked dry beans or dry peas; 1 egg; 1 tablespoon of peanut butter; or ½ ounce of nuts or seeds
- Protein-rich foods are good sources of micronutrients, especially iron, zinc, and B vitamins
Fruits
- Include fresh, dried, frozen, sauced, and canned fruit, as well as 100% fruit juice
- Serving size: 1 cup of fruit or fruit juice, or ½ cup of dried fruit
- Fruits are low in fat and good sources of phytochemicals and micronutrients, especially potassium and vitamins C and folate
- Choose whole or cut-up fruits instead of juices
Vegetables
- Include fresh, cooked, canned, frozen, and dried/dehydrated vegetables, and 100% vegetable juice
- Serving size: 1 cup of raw or cooked vegetables, 1 cup vegetable juice, or 2 cups of uncooked leafy greens
- Vegetables are good sources of micronutrients, fiber, and phytochemicals
- Choose a variety of vegetables, including dark green, orange and red, starchy, and "other" categories
Other Foods
- Oils include canola, corn, and olive oils, as well as other fats that are liquid at room temperature
- Sugary foods ("sweets") include candy, regular soft drinks, jelly, and other foods with high amounts of added sugar
- Choose "healthy" fats, such as nuts, seeds, and avocados, instead of saturated fats
Levels of Food Processing
- Raw foods can undergo different levels of processing, including refinement, before being eaten
- Minimally processed foods contain few refined ingredients and are closer to their natural state
- Ultra-processed foods contain numerous additives and are often high in sugar, salt, and unhealthy fats
- Nutrition experts are concerned about the negative health effects of eating diets high in ultra-processed foods
