I can't imagine why anyone who has survived any form of cancer would risk the side effects, which range from unpleasant to deadly, of anabolic steroid use. There is information online from the National Institute on Drug Abuse, part of the National Institutes of Health, at their website at
www.steroidabuse.gov.Your concern for the quality of the calories ingested is a good point. But when one is recovering from oral cancer, the advice is to eat what you can and don't worry about sugar and fat content. It is seen as a short term solution. Alex is still in recovery and as you have read in other posts, recovery times vary with each patient.
I love to cook and prior to Clark's OC, he loved eating the food I prepared. He just had his 3 year anniversary from diagnosis and surgery. He is just now beginning to get interested in food again. Eighty percent of his taste has returned and he enjoys most foods. Some things are forever changed, now he hates garlic which he used to love.
In the last three years, I introduced to my husband a huge variety of foods, tastes and textures to try and spark his appetite hoping that he would regain his interest in food. He appreciated my efforts but he needed the time it took to "get there".
There are really good cookbooks on preparing pureed foods available online through Amazon. If you decide to buy, your purchase can benefit OCF, too.
Good luck and hang in there!
