Diets high in fruits, vegetables and other foods with fewer calories per bite may lower an older women’s risk of breast cancer compared to women who eat lots of high calorie-dense foods, suggests a new study. The findings suggest the link is independent of overweight and obesity, a risk factor for postmenopausal breast cancer.
In this study researchers looked at energy density, the amount of calories in a certain weight of food, typically a gram. Cakes, ice cream and other foods heavy in oils and added sugars are high in energy density. Low energy-dense foods are higher in water and fiber, making these foods generally lower in calories for every gram. Vegetables, fruits and many unprocessed grains are generally low in energy-density.
Right now, the research does not show any strong link between eggs and ovarian cancer risk. There have been a few studies that have found a modest increased risk of ovarian cancer among women with the highest weekly egg consumption compared to those who don’t eat eggs. However, the studies that show a link are usually the study types more likely to have problems accurately estimating egg consumption and controlling for other potential influences on risk.
And many studies examining this link have not adjusted for being overweight, which increases ovarian cancer risk. A recent analysis of the global research on eggs and ovarian cancer risk by the American Institute for Cancer Research found that current evidence is too limited to support any conclusion. More research is needed.
Theoretically, high consumption of eggs’ cholesterol could lead to formation of compounds that pose risk. Yet it’s also possible that eggs’ rich content of choline (an essential nutrient) could play a role in maintaining healthy DNA to reduce cancer risk.

A recent study finds an intriguing connection between omega-3 fatty acids from fish and survival of colorectal cancer, the third most common and third deadliest cancer.
There is a lot of research on cancer prevention and omega-3 fatty acids, which come from fatty fish along with plant foods sources — like walnuts and flaxseed. This study focused on omega-3s from fish and cancer survivorship.
