A new study gives a good reason for young women to switch to whole grain bread and to generally increase the amount of whole grains in their diets. Conducted at the University of Leeds, the study showed that women who ate at least 30 grams of fiber each day cut their breast cancer risk by half.

The average fiber intake in the UK is 12 grams per day for adults and 15 g per day in the US. Since the results of the study suggest that benefits will not occur when women eat less than 20g per day, it is worth noting that there are a couple of easy ways to eat more fiber. A medium apple, for example, has 4g of fiber. An artichoke, cooked, has 4.5 grams. Beans vary in their fiber content, but tend to have around 16gper cup. 1/2 cup of corn has 5g. There are many other vegetables and fruits that provide low calorie ways to add fiber to the diet, as well.

The benefits of eating more fiber could be overridden by other factors, including weight, but a generally healthy lifestyle that includes the recommended amount of fiber should decrease the risk enough to make dietary changes worth the effort for young women.

Millions of people drink aspartame each day in their diet sodas and other sugar-free foods, though there are many other sweetener options to choose from. The brand name artificial sweeteners made with aspartame include Equal and Nutra-Sweet. In the past, study results have suggested that there might be a link between aspartame consumption and increased risk of some types of cancer, particularly when aspartame consumption was unusually high. Virtually all of these previous studies were in groups of rats, not people, and the amount of aspartame given to rats was up to several times their body weight - a feat which might be physically impossibly to do via diet cola consumption.

A new federal study has looked at people, not rodents, and shows that there was no increased cancer risk from aspartame consumption. The researchers in the study looked at over 500,000 American diets to draw their conclusions. The study has been praised by consumer groups and was presented to the American Association of Cancer research earlier this week.
