Hi. Shirley, Yes diet does play an important role in keeping healthy! Try to go for a long walk and try to relax. You have come to the right place for a wealth of information on how the body can be changed.
I suggest you read about the Dr. Budwig diet of flaxoil and cottage cheese as this is an important nutrient. It helps to deliver oxygen to your cells which cancer doesn't like and protects the healthy cells.
Go to the website http://www.lifestar.com and read about the cancer remission site and the rest of the products. After understanding more of what has to be done contact JOe at Lifestar about a good nutrition programs as he has helped our families and other. Then go to http://www.daystarbotanicals.com and read about Life Force and every ingredient thats in it cholrella and you will realize how important Gods created superfoods are to your general health.
Also read about changing your body PHS level from acid to alkaline and go to http://www.newstarget.com for info on health issues.
