The new Dietary Guidelines for Americans are out and they take a step in the right direction to help you make choices to lower your risk for cancer. Two key pieces of advice–eat a healthy diet that includes plenty of plant foods and keep sugary foods and drinks to a minimum. And that could mean fewer cases of cancer associated with poor diet and obesity.
You can put these into practice with our New American Plate model – filling at least 2/3 of your plate with vegetables, legumes, whole grains and fruit, and 1/3 or less with fish, poultry, meat and dairy.
The guidelines also recommend keeping your added sugar to 10 percent or less of your total calories. As we wrote earlier about the nutrition label and sugar, if you follow a 2000 calorie diet, you could have about one cup of fruit yogurt and one small dark chocolate bar. That’s because foods with high amounts of added sugar contribute to overweight and obesity, a cause of 10 cancers, including colorectal, postmenopausal breast and kidney.
Unfortunately, the Dietary Guidelines does not reflect the evidence-based recommendation from the independent expert committee to advise Americans to limit red and processed meat. It is disappointing that industry lobbying efforts succeeded in preventing the clear and simple message that these increase risk for colorectal cancer. AICR research has shown that red and processed meats are convincingly linked to colorectal cancer, and the World Health Organization has also recently established that link. Here’s our recommendation:
A fiber-rich bean-based meal can be just as satisfying as a protein-rich beef-based meal, according to a recent short-term study, published in the Journal of Food Science. The findings are good news if you want to cut back on red meat and up your fiber intake – both recommendations for cancer prevention.
This early study included 28 healthy adults (50% women) who consumed 2 “meatloaf” test meals on separate visits matched for portion size, calorie, and total fat content.
Meal one was a high protein beef meatloaf, about one-half the daily value of protein (26 grams), and one-eighth the daily value fiber (3 grams).
Meal two was a high fiber, moderate protein bean-based “meatloaf” – about one-third the daily value protein (17grams ), and half the daily value fiber (12 grams).
Researchers compared the effect of both meals on reported hunger, satiety, and fullness, as well as calorie intake at later meals.
For years, we’ve heard a lot about the heart health benefits of the Mediterranean Diet. Now an analysis from a randomized trial suggests this diet, supplemented with extra-virgin olive oil and nuts, may help lower risk of breast cancer.
The analysis, published in the Journal of the American Medical Association, is from the PREDIMED trial – a 6 year study that includes data from over 4000 women, 60-80 years old and at high risk for cardiovascular disease. The women had been assigned to follow one of three diets, a Mediterranean diet where they received extra virgin olive oil, a Mediterranean diet with provided mixed nuts, or they were advised to follow a low fat diet. The women had quarterly sessions with a dietitian to assess how well they were following the diet.
At the end of the study, the women following the Mediterranean diet with olive oil showed a 62% lower risk of malignant breast cancer than the control, low fat diet group. When researchers put the olive oil and nuts groups together, there was a 51% relative risk reduction compared to the control group.
