In botany, a fruit tree is a small fruity structure especially in flowering plants which is fully developed after flowering in a process called berry-making. This fruit is a fruit-bearing fruit and is made by the complete process of photosynthesis. In this process, sugar is produced from starch via photosynthesis and stored in the leaves as glucose. The plant derives food from this stored glucose and stores it in the fruits for later use
This is the reason why fruits and vegetables are rich in plant chemicals that have a great value in the manufacture of medicines and foods. These chemical substances make the product useful to us humans since they have medicinal value. These compounds, called phytochemicals are present in high concentration in certain fruits and vegetables which is why they have a high value for health conscious people. Below are some of these phytochemicals, which are very useful to us:
– Lycopene is an extremely powerful antioxidant that can prevent cancer development. It also prevents cancer cells to thrive and spread and promotes prevention of other diseases which are caused by free radicals. Therefore, fruits and vegetables contain lycopene that can prevent cancers at an early stage.
– anthocyanins are found in almost all kinds of fruits and vegetable and they have a strong antioxidant that helps to protect human health and slows down aging. This is because anthocyanins works as a highly efficient water absorbor helping fruits to store more nutrients and reduce dehydration. Many fruit juices are available in the market containing anthocyanins and are a good source of dietary antioxidants.
– Carotenoids are a group of beta-carotene pigments that are responsible for giving red color to fruits and vegetables. Also, they have a strong antioxidant which helps to prevent cancer development and promotes prevention of other diseases which are caused by free radicals. Therefore, fruits and vegetables include foods which include carrots, tomatoes, cabbage, broccoli and many more which are rich in carotenoids. Green leafy vegetables include kale and lettuce, which are a rich source of vitamin A. Moreover, fruits include apples, oranges, strawberries and carrot which are also rich in antioxidants.
– Resveratrol is a phytoalexin produced by plants which have a great beneficial effect in preventing cancer and fighting many other chronic diseases including cardiovascular ailments. Studies have shown that there is a high content of resveratrol in red wine which is probably due to fermentation method and different treatment procedure which the grapes undergo. Another benefit of resveratrol is that it contains loads of nutrients such as Vitamins A, D, E, K and C which are vital to keep the body healthy. Therefore, fruits and vegetables contain loads of other plant chemicals that are excellent sources of nutrients.
