What are the three major food groups?

There is no widely accepted "three major food groups" system. The concept of food groups is primarily used to help people understand the different types of foods they need to eat for a healthy diet.

Historically, the "Food Guide Pyramid" and its successor, "MyPlate," have been used to categorize foods into groups. These systems emphasize variety and balance:

MyPlate (updated in 2011) divides food into five groups:

* Fruits: Provide vitamins, minerals, and fiber.

* Vegetables: Provide vitamins, minerals, and fiber.

* Grains: Provide carbohydrates, fiber, and some vitamins and minerals.

* Protein Foods: Provide protein, iron, and B vitamins.

* Dairy: Provides calcium, vitamin D, and protein.

While these systems are helpful, it's crucial to understand that all food groups are important for a balanced diet. The specific amounts and types of food needed will vary based on individual factors like age, activity level, and health goals.

It's always best to consult with a registered dietitian or other qualified healthcare professional for personalized dietary advice.
