Berries are fruits which are generally small and quite fragile. Grapes are physically fragile and fruits I cluster. Melons on other hand are large and have tough outer rind. Drupes contains single pit and includes items such as peaches and plums, cherries etc. Pomes contains many pits and are represented by apple, pears etc. citrus fruits like oranges and grapefruit are high in citric acid. Tropical and subtropical fruits includes bananas, dates, pineapple, mangoes and other which require warm climates.

Most fresh fruits and vegetables are high in water content (>70 %), low in protein (≯3.5%) and low in fats (≯5%). However there are some exceptions. Legumes such as soybean and other beans are high in protein. Few vegetables such as sweet corn are high in fat and avocados are rich source of fat (19 – 22%)

Fruits and vegetables are important source of both digestible and indigestible carbohydrate. Digestible carbohydrate are present largely in form of sugar and starches while indigestible cellulose provide roughage which is important to normal digestion. Fruits and vegetables are important source of vitamins and minerals.
