Nutrition and diet, combined with a consistent exercise regimen will make you feel and look better, and will help your body recover. Try to eat a whole grain diet, plenty of fruits and vegetables and avoid excess sugar and fried or processed foods. Drink plenty of water and avoid sugary beverages.
Watch your alcohol intake, as above-average levels of alcohol consumption can increase the risk of cancer as well as a host of other health issues. You should avoid smoking, as that can also cause a myriad of health problems, from emphysema to lung cancer.
