SMART Lifestyle Choices = REDUCED Cancer Risk

Several studies have shown that high intake of red and processed meats, highly refined grains and starches as well as sugars are all factors related to an increased risk of colon cancer. Replacing these foodstuffs mainly with fatty fish and plant sources as the primary source of protein; unsaturated fats as the primary source of fat; as well as unrefined grains, legumes and fruits as the primary source of carbohydrates is likely to lower the risk.

Dr O’Keefe’s research explores the field of nutritional gastroenterology. Most of his investigations are translational in nature, evaluating the physiological and pathophysiological responses to dietary intake and interventional feeding. His current major area of NIH-supported research investigates the role diet, colonic microbiota and the metabolome to determine colon cancer in diverse populations. His studies seek to unravel the reasons for the high risk of colon cancer among African Americans in the U.S., while rural Africans in Africa rarely get the disease. Dr O’Keefe has formed a collaborative team from South Africa, the UK and The Netherlands to achieve these aims. Currently, this group is investigating the effects of dietary exchanges on the microbiota and colonic mucosal biomarkers of cancer risk. Read more about Prof O’Keefe here
