Напишите письмо джону, объясняющее, почему вредно есть фастфуд

hello,josh! i think that fast food is harmful for us.now let me prove my point of view. firstly, fast food hasn`t got any vitamins which are necessary for health. secondly, a lot of people like to eat hamburgers and drink coca cola, sprite, fanta and another harmful soda . but what is tasty isn't always healthy. fast food makes you fat. thirdly, fast food destroys people`s health. that’s why many people become very nervous.but somepeople are quite sure that fast food is very convenient for people with busy lives because it saves time. but i think, that if you want to save time-you can make some salad,vegetable soup at home and bring it with you, or take fresh fruit. at the end of my letter, i want to say that i prefer to eat fruit and vegetables rather than fast food because i think that it helps me to save my health. of course, i can’t but agree that the problem needs further discussion. there are many people, there are many opinios. and what do you think about fast-food? do you eat it?
