помогите выбрать заголовки к каждому из текстов.
l. Read an article and match the headings (A-F) to the paragraphs (1-5). There is one extra heading which you do not need to use.
A Be Careful What You Buy
B Dangerous Diets
C Life in the Fast Lane
D Can You Give up Chocolate?
E Some Healthy Advice
F You Know What's Good for You
EAT YOUR WAY TO GOOD HEALTH

1._________________________________________________________________
We all know that a varied diet with the right combination of protein, carbohydrates and fresh fruit and vegetables is necessary for good health.
2._________________________________________________________________
However, modern living and a busy lifestyle often mean that many of us don't have time to eat proper well-balanced meals. We seem to be relying too much on 'fast foods' to match our fast lives. The problem with these foods though is that they are high in bad things like fat and calories, but low in the good things like vitamins and minerals. If you are only eating this sort of 'junk' food, then you've got a poor diet.
3. _______________________________________________________________
A poor diet can lead to lots of health problems. These include allergies and tiredness or much more serious illnesses such as cancer and heart disease. The additives which are put in processed foods can also cause illness. Additives are used to add colour, flavour and long life to foods, but they can be quite harmful if you eat too many of them.
4._______________________________________________________________
If you eat raw and organic foods - you will be much healthier. Therefore, it makes sense to eat organically grown fruit and vegetables whenever you can. Try to stop drinking coffee and stop using sugar, too. Also, it is good idea to take vitamin and mineral tablets if you know your diet is not as healthy as it should be.
5.________________________________________________________________
A good time to think about healthy eating is when you are shopping, read the list of ingredients on food packets to find out if there are a lot of additives so you can avoid them. Foods that contain a lot of additives include: processed meats, soft drinks, tinned fruit, margarine and biscuits.
All in all, a few simple changes to your diet can make a big difference to your health. Eat the right things and you can eat your way to good health.
