what should a healthy person eat every day? well,I will introduce my "healthy eating habit" ,it comes from doctors,and it is believable. while people do a lot of work,the energy in their body are burning,too.so you need rice,milk,bread and eggs.ifyou don'teat them,you will faint.fruit and vegetables are necessary,too.they are a lot of vitamins.it makes you not sick easiy vegetables help the other food easier to be digested.
