 Broccoli may combat breast cancer
 New research shows that a natural compound sourced from broccoli may help fight breast cancer. In tests on mice, scientists found that sulforaphane could target and kill stem cells, which are known to promote the growth of tumors, help stop new tumors from growing.

Since scientists have yet to test sulforaphane's effects in humans, the study's authors do not suggest that people looking to treat or prevent breast cancer add sulforaphane supplements to their health regimen at this time.

In previous studies, a number of other natural compounds have shown promise in protection against breast cancer. For instance, test-tube research suggests that resveratrol may help suppress breast-cancer progression in its earliest stages, while a combination of green tea and ganoderma.

 Soy supplements show no diabetes benefit
 Adding soy supplements to the diet may not improve blood sugar control in older women who are at high risk of or in the early stages of type 2 diabetes, a new study suggests. The findings, reported in the American Journal of Clinical Nutrition, add to the conflicting body of research on soy and diabetes risk.

Lab research has suggested that soy proteins and soy isoflavones -- "phytoestrogen" compounds that are structurally similar to human estrogen -- may help control blood sugar levels. However, so far, the few small clinical trials that have been done have reached different conclusions as to whether soy foods or soy-protein supplements are beneficial to people with diabetes. For this latest study, researchers in Hong Kong recruited 180 postmenopausal women who either had "pre-diabetes" -- blood sugar levels that are elevated but not high enough for a type 2 diabetes diagnosis -- or were in the early stages of diabetes and had not yet started any treatment.

These women were divided in to three classes. All three groups were told to mix the supplement with a drink each morning but otherwise maintain their normal diets.

After six months, team found no clear benefit of either the soy or the milk-plus-isoflavone supplement in the women's blood sugar control or levels of the blood-sugar-regulating hormone insulin.

However, the findings should not be seen as the final word on soy and diabetes, according to Liu's team. They note that this appears to be the first controlled clinical trial designed to specifically look at the effects of soy supplements in people with pre-diabetes or early, untreated type 2 diabetes.

 Nuts may keep cholesterol in check
 Nuts are an important source of nutrients for both humans and wildlife. They are a composite of the seed and the fruit, where the fruit does not open to release the seed. New research shows that nuts may offer a natural approach to cutting cholesterol. In a review of 25 clinical trials with 583 participants, scientists found that consuming about 2.4 ounces of nuts daily was linked to an average 5.1 percent drop in total cholesterol levels. That same amount of nut consumption was also associated with a 7.4 percent decrease in LDL (Low-Density Lipoprotein) cholesterol and an 8.3 increase in HDL ( High-Density Lipoprotein ) cholesterol.

Rich in healthy fats, fiber, vitamins, minerals, and antioxidants, nuts may be helpful in lowering risk of heart disease, according to the study's authors. A number of other foods may also help you achieve healthy cholesterol levels and protect heart health. What's more, some studies suggest that certain natural substances may help keep cholesterol in check as well.

Previous studies revealed that people who consume nuts regularly are less likely to suffer from Coronary Heart Disease (CHD). Nuts contain the all important fatty acids, linoleic and linolenic acids, which are critical for growth, physical and mental development, healthy hair and skin, blood pressure control, immunological responses and blood clotting.

 Chokeberry may protect against weight gain
 Chokeberry, a bright-red and dark-purple fruit rich in antioxidants may help protect against weight gain and keep blood sugar in check, according to a new animal study.

For the study, researchers focused on a group of rats with pre-diabetes, which is a condition in which blood sugar levels are abnormally high, but not high enough for a diagnosis of diabetes. For six weeks, the rats drank either pure water or water infused with high levels of chokeberry extract.

At the end of the six-week period, researchers found that chokeberry-fed rats weighed less and had less body fat than the animals that drank pure water. Compared to the control group, the chokeberry-fed rats also had lower levels of cholesterol, blood sugar, blood fats, and inflammation.

Chokeberry is high in anthocyanins, a type of antioxidant also abundant in natural remedies like bilberry, tart cherries, and elderberry. Chokeberries are low in calories and fats but are rich source of vitamins, minerals, antioxidants and dietary fiber. Chokeberries compose significantly high amounts of phenolic flavonoid phyto-chemicals called anthocyanins. Previous studies have shown that consumption of berries on regular basis offers potential health benefits against cancer, aging and neurological diseases, inflammation, diabetes, and bacterial infections

 Ancient yoga eases sleep problems among cancer sur
 Cancer survivors who participated in a month-long program in the ancient art of yoga reported enhanced quality of life, better sleep, less fatigue and less need for sleep medications.

The study authors involved 410 cancer survivors, average age 54, who had finished treatment two to 24 months before and who still reported greater-than-average sleep disruptions. Almost all of the participants were women, and three-quarters had had breast cancer, although the cancer had not spread. None had done any yoga in the past three months.

Participants were randomized either to receive regular follow-up care for cancer survivors or to receive regular care plus two 75-minute sessions of yoga per week for four weeks. During study, emphasis was on breathing from the diaphragm rather than the chest and on mindfulness, visualization and guided meditation. Yoga participants reported an improvement in sleep quality of 22 percent, while controls reported an improvement of only 12 percent.

Thirty-one percent of participants in the yoga group who had started out with clinically impaired sleep quality recovered vs. only 16 percent in the control group. Fatigue in the yoga group was decreased by 42 percent, compared with only 12 percent in the control group.
