What are the basic seven food groups?

There isn't a universally accepted "basic seven" food groups anymore. The concept of food groups has evolved over time.

Previously, there was the "Basic Four" (1950s):

* Fruits and Vegetables: For vitamins, minerals, and fiber

* Milk: For calcium and protein

* Meat: For protein, iron, and B vitamins

* Bread and Cereals: For carbohydrates, fiber, and B vitamins

Then came the "Food Guide Pyramid" (1992):

* Grains: For carbohydrates, fiber, and B vitamins

* Vegetables: For vitamins, minerals, and fiber

* Fruits: For vitamins, minerals, and fiber

* Milk, Yogurt, and Cheese: For calcium, vitamin D, and protein

* Meat, Poultry, Fish, Dry Beans, Eggs, and Nuts: For protein, iron, and B vitamins

* Oils: For healthy fats

Today, the recommended way to think about food is through "MyPlate" (2011):

* Fruits: For vitamins, minerals, and fiber

* Vegetables: For vitamins, minerals, and fiber

* Grains: For carbohydrates, fiber, and B vitamins (choose whole grains)

* Protein: For protein, iron, and B vitamins (choose lean sources)

* Dairy: For calcium, vitamin D, and protein (choose low-fat or fat-free options)

Important Note: MyPlate emphasizes balance and variety within each food group, rather than strict adherence to a specific number of groups. It also encourages healthy portion sizes and mindful eating.
