"Cancer patients would be shocked if they knew just how much of a benefit physical activity could have on their recovery and long term health, in some cases reducing their chances of having to go through the grueling ordeal of treatment all over again. It doesn't need to be anything too strenuous; doing the gardening, going for a brisk walk or a swim, all count."
During the Paleolithic period, about 12,000 years ago, people ate primarily non-starchy vegetables, fruit, nuts, roots and lean meat, including ostrich and bison as well as organ meats and seafood—a far cry from the standard American diet. Today, these healthy staples have been largely replaced with refined sugar, high fructose corn syrup, cereal, bread, potatoes and pasteurized milk products … which are doing you no favors in terms of health. During the Paleolithic period our ancestors didn't die of heart disease, diabetes and cancer -- which are among the leading causes of death today, and all are related to diet.
The primary disease-causing culprits in the modern diet are sugars, particularly fructose, and grains. If you want to avoid heart disease, high cholesterol, type 2 diabetes or even cancer, you'll want to severely restrict your fructose and grain consumption.
Remember that even if you're chronically ill, exercise can be a potent ally. That said, if you have cancer or any other chronic disease, you will of course need to tailor your exercise routine to your individual scenario, taking into account your stamina and current health. For example, you may at times need to exercise at a lower intensity, or for shorter durations, but do make a concerted effort to keep yourself moving. As mentioned above, even cancer patients should aim for a minimum of 2.5 hours of exercise a week, at moderate intensity, to boost their chances of successful recovery.
Always listen to your body and if you feel you need a break, take time to rest. But even exercising for just a few minutes a day is better than not exercising at all.
