Study Notes

Major Food Groups

Major food groups are classified based on their natural origins and key nutrients, and include:
- Grains (e.g. wheat, rice, oats)
- Dairy products (e.g. milk, yogurt, cheese)
- Fruits (e.g. fresh, dried, frozen)
- Vegetables (e.g. fresh, cooked, canned)
- Protein-rich foods (e.g. beef, pork, lamb, fish, shellfish, poultry, beans, eggs, nuts, seeds)
Each food group has specific serving sizes and recommendations for daily intake.

Grains

Include products made from wheat, rice, and oats (e.g. pasta, noodles, flour tortillas)
A serving of grain food is equivalent to 1 slice of bread, 1 cup of ready-to-eat cereal, or ½ cup of cooked rice, pasta, or cereal
Whole grains are preferred over refined grains because they contain more fiber and nutrients
Refined grain products are commonly consumed in the US and can be good sources of vitamins and minerals when enriched or fortified.

Dairy Products

Include milk and products made from milk that retain their calcium content after processing (e.g. yogurt, hard cheeses)
Excellent sources of protein, phosphorus, and riboflavin
Fortified with vitamins A and D
Milk-based desserts (e.g. ice cream, pudding, frozen yogurt) are often grouped with dairy products but are high in added sugar and fat
Nonfat or low-fat milk is recommended over whole milk due to lower fat content.

Protein-Rich Foods

Include beef, pork, lamb, fish, shellfish, poultry, beans, eggs, nuts, and seeds
Serving sizes vary, but generally equal 1 ounce of meat, poultry, or fish, or ¼ cup cooked dry beans or dry peas
Excellent sources of micronutrients, especially iron, zinc, and B vitamins
Dry beans and peas, eggs, tofu, nuts, and seeds are protein-rich foods that can substitute for meat.

Fruits and Vegetables

Fruits include fresh, dried, frozen, sauced, and canned fruit, and 100% fruit juice
Vegetables include fresh, cooked, canned, frozen, and dried/dehydrated vegetables, and 100% vegetable juice
Serving sizes vary, but generally equal 1 cup of fruit or fruit juice, or ½ cup of dried fruit
Excellent sources of phytochemicals, fiber, and micronutrients

Other Foods

Oils include canola, corn, and olive oils, as well as other fats that are liquid at room temperature
Solid fats, such as beef fat, butter, and stick margarine, are high in saturated fats and associated with cardiovascular disease
Sugary foods ("sweets") include candy, regular soft drinks, jelly, and other foods high in added sugar
Alcohol-containing beverages are another source of empty calories.

Levels of Food Processing

Raw foods can undergo different levels of processing, including refinement, before they are eaten
Minimally processed foods, such as canned carrots, typically contain few refined ingredients
Ultra-processed foods, such as frozen carrot cake, contain numerous additives to extend shelf life, enhance flavor, texture, color, and convenience
Nutrition experts are concerned about the long-term negative health effects of eating diets high in ultra-processed foods.
