Fruit,” on the other hand, does: it’s any part of a plant that contains a seed or seeds. To a botanist, an apple is a fruit. Avocados are fruits, not vegetables: • Botanical classification: Avocados meet the botanical definition of a fruit because they develop from the ovary of a flower and contain seeds.Are Olives a vegetable or fruit? Much like the tomato, olives walk the fine line between being both a vegetable and a fruit. Technically speaking, they are a fruit as they contain a seed and grow from the flower of a plant.Except by that same definition, tomatoes aren’t the only entities which we think about as vegetables, but which are technically fruits. Other plants that are biologically considered fruits include peppers, eggplants, olives, squash, avocados, cucumbers, beans and some nuts.
Do humans actually need to eat vegetables?
Fruit and vegetables are a good source of vitamins and minerals, including folate, vitamin C and potassium. They’re an excellent source of dietary fibre, which can help to maintain a healthy gut and prevent constipation and other digestion problems. A diet high in fibre can also reduce your risk of bowel cancer. While fruits and vegetables are healthy, it’s dangerous to eat them exclusively without any other food groups. Only eating fruits and vegetables can lead to deficiencies in iron, protein, and other key nutrients.
