I am constantly suggesting on this blog that you eat whole grains and throw out any refined grains in your pantry. And yes, I am repeating myself here again today. As one who has survived colon cancer and several colon surgeries, let me strongly recommend you follow that advice. Today I read a new report that said according to a Danish study of 108,000 people, eating 3 to 5 servings of grains a day lowers the risk of colorectal cancer (a very deadly cancer). And remember that whole grains also protect against heart disease, type 2 diabetes and other chronic diseases. If you think you don't like whole grains, let me assure you that in most cases you will hardly notice the difference.
I recommend you give this serious consideration. I have had colorectal cancer, a heart attack, and I am a type 2 diabetic. But because of changes in my diet I am quite healthy today. I am required by my insurance company to have lab work, etc every three months and a complete physical annually. Since making changes in my diet, I always get good results. So yes, I do 'practice what I preach' and you should, too.
