One-third of breast cancer cases may be avoidable

Supporters of eating less and exercising have won yet again as results from a new study have been divulged. According to researchers, around a third of all breast cancer cases in Western countries could possibly be avoided if women consumed less food and exercised more.

Even though early diagnosis, mammograms and better treatments have helped to slow the disease, experts are now focusing on changing unhealthy behaviors like overeating and being too sedentary.

This new study only adds to a string of existing findings that lifestyle changes in areas such as smoking, eating, exercising and sun exposure can have a crucial effect on all kinds of cancer rates.

The head of epidemiology, Carlo La Veechia, emphasized the importance of  taking these findings seriously when he said “what can be achieved with screening has been achieved. We can’t do much more. It’s time to move on to other things.” He spoke last month at a European breast cancer conference in Barcelona.

Michelle Holmes, a cancer expert at Harvard University, warned that people might mistakenly believe that their likelihood of getting cancer leans more on their genes than on their lifestyle.

Breast cancer is currently the most common cancer among women. In Europe, around 421,000 new cases and almost 90,000 deaths occurred in 2008. Last year in the United States, there were more than 190,000 new cases  and  40,000 deaths.

During an average woman’s lifetime, her chance of developing breast cancer is around one in eight. According to a 2006 study by British researchers, obese women are up to 60 percent more likely to develop any cancer than normal-weight women.

Numerous breast cancers are encouraged by estrogen, which is a hormone manufactured in fat tissue. This is why experts believe that the more fat a woman has, the more estrogen she is likely to produce, which could initiate breast cancer. This said, even slim women can help reduce their cancer risk with exercise by converting more of the body’s fat into muscle.

The American Cancer Society now recommends that women get 45 to 60 minutes of physical activity for five or more days a week to reduce their chances of getting breast cancer.

Some good news for women who have survived breast cancer and want children; a separate study has found that breast cancer survivors who have children later, do not seem to be at any more risk for dying from cancer. For a long time, doctors have been troubled that pregnancy could ignite hormonal changes which could cause the disease to return. For this reason, many women have been told to avoid getting pregnant after they recover from cancer. The European breast cancer conference had experts who announced that cancer survivors who get pregnant are safe and it does not appear to be linked to the disease’s recurrence.

Diet may have strong affect on depression

Here’s yet another reason to listen to your mother when she says to make sure you eat your fruits and vegetables. A new study in the British Journal of Psychiatry has found that those who regularly eat fish, fruit, and vegetables decrease their chances for developing depression.

About 3,500 British civil servant’s diets were observed by scientists at London’s University College. Five years later they evaluated the individuals symptoms of depression. These researchers pointed out the beneficial effect of a whole-food healthy diet that seemed to protect those who consumed it. On the flip side, they found that those who ate a poor diet consisting of sweets, processed meats, fried food, refined cereals and high-fat dairy foods appeared to make them more vulnerable to depression.

The study drew attention to a link between diet and depression. This doesn’t necessarily mean that a poor diet definitely causes depression, but these results are compelling. So what is most likely giving the protection for good mental health? The researchers suggested a variety of possibilities. Maybe it could be the antioxidants in fruits and vegetables believed to protect cells from harm, the folic acid found in leafy greens that affects brain tissue, or the omega-3 fatty acids in fish that are found in specific brain membranes. Or they theorized that the benefits could be from a combination of all of these factors.

Study finds cholesterol drugs not needed for most teens

A new study provides some encouraging news concerning childhood obesity. It found that less than 1 percent of American teens are anticipated to need cholesterol drugs.

Alarming new guidelines were announced last year by the American Academy of Pediatrics: Doctors were called on to consider cholesterol medicine for more kids, sometimes as young as 8, if they had elevated levels of “bad cholesterol,” or LDL, accompanied by other health issues such as obesity and high blood pressure.

the academy did not talk about the amount of children that be included in that group. A study that was announced on February 16 in the American Heart Association’s journal Circulation helps diminish anxiety about many children that might need to be on cholesterol medicine, according to Dr. Stephen Daniels, who is the main author of the pediatric guidelines.

He said that there was a worry that a rising amount of obesity cases would lead to an increase in cholesterol levels. He said that they don’t seem to be increasing.

The new pediatrics guideline was established from indicators that damage leading to heart disease starts in early life. Simultaneously, current research has revealed that drugs used to lower cholesterol are basically safe for children.

Dr. William Scott, a cardiologist and pediatrics professor at the University of Texas Southwestern Medical Center, said that as long as a child does not have an inclination to high cholesterol, regular exercise and a healthy diet should keep the cholesterol under control. Scott said, “You really are empowered by your diet and activity.

Kids’ TV watching can influence eating habits in later years

Can watching TV make you fat? There are some increasing amount of indicators that link too much TV viewing to becoming overweight or obese.

The most recent study on eating habits has revealed that kids who watch more TV than other kids in middle and high school have diets that are not as healthy 5 years later. During this time, these kids tend to eat more fast food, fried foods and sugary drinks and eat less fruits, vegetables and whole grains.

The lead researcher of this study, Daheia Barr-Anderson said that they don’t know what exactly links TV and diets, but she knows there is a definite connection. She said that there are a lot of commercials for snacks and soda on TV that target children, and this tends to affect their food choices. Also, many lifelong habits are shaped in the adolescent years, such as a tendency to snack and watch TV.

American adolescents definitely play a role in the obesity upswing. Fewer than 5% of 12-19 year olds were overweight in the mid-1960s, but today there are about 17% who are overweight and another 17% who are obese.

In earlier studies, Harvard researchers found that for each hour of TV watching, kids ate an extra 167 calories a day, mainly because they usually eat more junk food. The University of Missouri-Columbia advocates that the combination of family meals and less TV can help kids to avoid getting overweight.

This most recent study was conducted on a survey of 2000 middle and high school children in Minneapolis and St. Paul, Minnesota. This study was different, because it compared the subjects’ behavior in two separate time periods instead of at the same time. It can be found in the International Journal of Behavioral Nutrition and Physical Activity.
