Lack of vitamin A can lead to night blindness, which can be very dangerous, especially when the person is driving a car. An easy way to find out if you are lacking in vitamin A is to walk from a bright room into a dark room. Your eyes may have some trouble in getting used to the change of light if you are lacking in vitamin A.

The flavonoid found in green tea is called EGCg- a stronger matter than Vitamin C and E. It is believed to be 20 times stronger than these mentioned vitamins.

Fruit also makes up a flowering plant. It carries the seeds . The purpose of fruit is to protect a plant’s seeds and help them get spread about. Wind and water spread seeds .So do animals when they eat fruit and drop the seeds .
There are two main types of fruit: fleshy and dry. Fleshy fruits are soft and juicy , the way we usually think of fruits . Peaches ,plums ,and apples are all fleshy fruits . Dry fruits are thin and hard . Grains like wheat and rice , or nuts are dry fruits.
You’ve eaten seedless oranges and grapes . How can they be fruits? It’s because people have changed the way they grow fruit. They can now grow seedless fruit . Seedless fruit comes from special plants called hybrids(杂交生物体) . A hybrid is made by combining two varieties of a fruit to form a new variety . This hybrid grows and produces seed
s . But the plants grown from these seeds are seedless . These plants cannot reproduce themselves.
A tomato is a vegetable , right? No , it’s actually a fruit . Other food we think of as vegetables—such as squash , peppers ,and eggplant—also are fruit . They’re fruit because they carry seeds and develop from flowers . Here’s another surprise . Scientists classify the tomato as a berry(浆果) . In addition , th
ey don’t consider some fruits we call berries to be true berries because a berry is normally a type of fruit with a lot of seeds inside it . Technically ,
a strawberry , isn’t a berry , because it has its seeds on the outside . The red part is just the tip of the strawberry stem that’s enlarged.
Fruits are a source of nourishing(滋养) substances that keep us alive and healthy . For example , they contain many vitamins , especially vitamins A and C, and many minerals . They also provide fibre for a healthy digestive system and carbohydrates that the body needs to make energy.
