Study: Carotenoids Lower Risk of Breast Cancer, Recurrence

Having plenty of tomatoes, carrots and other foods high in carotenoids may reduce the risk of breast cancer, especially the most deadly types, suggests a new study that spanned 20 years. The study, published in The American Journal of Clinical Nutrition, adds to a growing body of research on carotenoids, diet and breast cancer risk.17539703_s

Carotenoids are a large group of phytochemicals that you can spot in many red, orange and yellow fruits and vegetables. Beta-carotene and lycopene, found in carrots and tomatoes to name a few foods, are a couple of the more well-known carotenoids. They’re also in dark green vegetables, such as kale and spinach.

Previous studies on carotenoids and breast cancer have been mixed. This study builds on research by the same group suggesting that carotenoids affect different types of breast tumors. We wrote about that here.

As in their previous study, the researchers used blood levels of carotenoids to measure intake. Back in 1989-90, they collected blood samples from almost 33,000 women who were part of the Nurses Health Study. Ten years later they collected another sample, with slightly less than half of the women participating again. All the women were regularly answering questionnaires about their health, weight, diet and other factors. Continue reading


Exercising Daily 15 Minutes and More, Reduces Liver and Belly Fat

We’ve been talking a lot about preventing liver cancer here with the release of our new report. Among other factors, the report concluded that obesity increases risk of liver cancer —  a cancer that can stem from non-alcoholic fatty liver disease (NAFLD).

Belly fat, also called visceral fat, is a sign of poor metabolic health and another risk factor for many cancers.

Non-alcoholic fatty liver disease has become the most common cause of liver disease in the US; it can lead to cirrhosis, which could develop into cancer. People with non-alcoholic fatty liver disease have extra fat in their liver that doesn’t come from alcohol. Weight loss and exercise are the basic recommendations for obese people who have NAFLD. But what intensity exercise and how much was the focus of this study. Continue reading


New Study on Popular Diets: What’s Best for You

Perhaps you’ve struggled to find a diet that works for you, despite the almost overwhelming number of choices. And research seems to yield varying results. This is important because being a healthy weight can lower your risk for chronic diseases like type 2 diabetes and many cancers.Planning of diet.

A new study of popular diets in the Annals of Internal Medicine, completed a systematic review of controlled trials of popular diets and weight loss programs to look at their effectiveness at 12 months. These included Weight Watchers, Jenny Craig, Medifast, Atkins, SlimFast, eDiets and the LoseIt! app among others.

The authors concluded that Weight Watchers and Jenny Craig programs have the most robust evidence for people losing weight at one year when compared to doing nothing or simply getting general education about weight loss. They cited Nutrisystem as showing promise after a few months, but it lacks long-term results. These programs are all considered to be high intensity – meaning they include at least 12 individual or group counseling sessions. Continue reading
