Nutrition is possibly the single most important issue for body builders and elite athletes, or for that matter anyone who values good health. You can train as much as you like, but if your body is not getting the right nutrients, all that will happen is you will not achieve your goals, or you could become sick and even cause permanent damage. It's a little like running a car. If you don't put oil, water and petrol in it, it won't run properly and you can very easily damage it.
Nutritionists agree that you need a good selection of fresh produce every day. There is no substitute for this as being the base of your approach to nutrition. As a performance athlete or bodybuilder you will need to make sure that your body is getting all the protein it needs, but you also need to guard your immune system. When you train hard the immune system can be more at risk, and the right vitamins and minerals can help there.
You need to make sure you have enough carbohydrates for energy, and some oils are also important such as fish oil and pure olive oil. You need to be careful of packaged foods because they often contain hidden sugars and fats. There has been much talk of 'trans fats' lately which are implicated in a range of diseases, and some talk of banning them, but for practical purposes fresh is always best.
There is a myth amongst some bodybuilders that you need to eat a lot of meat to gain mass. That isn't the best approach.
