A great nutrition tip you should know about is to invest in creatine if you're interested in gaining muscle. Creatine is naturally produced in the body and it's great for muscle recovery. Taking creatine can make you bloated, but it's only water weight so it's nothing you should worry about.
Pay attention to what you drink as well as what you eat, in order to prevent sabotaging your efforts at improving your health. For example, most people think diet soda is healthier than non-diet soda. Although it often contains no calories or sugar, diet soda does contain artificial sweeteners. These sweeteners have been linked to potentially heightened risks of Type II diabetes and stroke.
You probably just learned a lot about nutrition: which of these tips are you going to adopt? If you are still unsure of what to do, you should give healthy nutrition a chance by watching your diet for a few weeks. The results should convince you that watching what you eat is good for you.
