Eat well, be well

I think that all food is necessary for the body as long as you don't eat to excess (or "too much"). Of course, we have to eat fruit and vegetables, but we also need red meat, chicken and fish at least once a week. In our familymeals I always include in the family meals legumes, cereals, dairy products and starchy foods.

Very well done!

I think that all (types of) food are neccesary for the body as long as you don't eat too much! Of course, we have to eat fruits and vegetables, but we also need red meat, chicken and fish at least once a week. In my meals I always include in the family meals legumes, cereals, dairy products and starchy foods in the meals I prepare for my family.

Charrid's correction is fine as well.  This is another way to say the same thing.

You can use fruit or fruits in this sentence.  It is considered a uncountable noun.  Because you are using vegetables, I think it sounds better to use fruits.

Nice job!
