     Nowadays, in the United States and other western countries, some teens are choosing to become

vegetarians.  That is, they choose not to eat meat.  There are many types of vegetarians, some of whom

don't even eat animal products such as milk, eggs, or yogurt. Having balanced meals is very important,

especially for teens who are growing up. So why are they becoming vegetarians? Well, they choose to

become vegetarians for different reasons. The most popular reason is just wanting to be healthier.

     I decided to become a vegetarian when l was 10 years old,  and it was much easier than you might

think.  But as a vegetarian,I have had a difficult time getting the proper  nutrition. Most doctors and

scientists say that being a vegetarian is very healthy, but many people aren't choosing the correct food

to supplement the protein in meat.

     If you're thinking about becoming a vegetarian, make sure that you pay attention to your diet very

carefully.  And of course, pay special attention to your health when doing so. Being a vegetarian isn't

for everyone, so don't be discouraged if you can't give up hamburgers and meat dumplings! Vegetables

play an important role in people's daily meals, so even if you are not a vegetarian, they are still good for

you.
