The Healthiest Food Group? – Nutrition Tier Lists: Fruits

A number of foods that are considered fruits by botanists are part of the Vegetable Group. For example, tomatoes, avocados, eggplants, cucumbers, green peppers, zucchini, butternut squash, and others are classified as fruits by botanists because they are the fleshy plant part surrounding its seeds. However, for nutritional and culinary purposes, these foods are considered to be vegetables rather than fruits.Vegetables may be raw or cooked, fresh, frozen, canned, or dried/dehydrated; and may be whole, cut-up, or mashed. Vegetables are organized into 5 subgroups based on their nutrient content: dark-green vegetables, beans and peas, starchy vegetables, red and orange vegetables, and other vegetables.
