An apple a day might keep obesity away

Turns out the old saw was right. An apple a day can keep the doctor away.

Scientists at Washington State University have concluded that nondigestible compounds in apples – specifically, Granny Smith apples – may help prevent disorders associated with obesity. The study, thought to be the first to assess these compounds in apple cultivars grown in the Pacific Northwest, appears in the print edition of the journal Food Chemistry.

“We know that, in general, apples are a good source of these nondigestible compounds but there are differences in varieties,” said food scientist Giuliana Noratto, the study’s lead researcher. “Results from this study will help consumers to discriminate between apple varieties that can aid in the fight against obesity.”

The tart green Granny Smith apples benefit the growth of friendly bacteria in the colon due to their high content of non-digestible compounds, including dietary fiber and polyphenols, and low content of available carbohydrates. Despite being subjected to chewing, stomach acid and digestive enzymes, these compounds remain intact when they reach the colon. Once there, they are fermented by bacteria in the colon, which benefits the growth of friendly bacteria in the gut.

The study showed that Granny Smith apples surpass Braeburn, Fuji, Gala, Golden Delicious, McIntosh and Red Delicious in the amount of nondigestible compounds they contain.

“The nondigestible compounds in the Granny Smith apples actually changed the proportions of fecal bacteria from obese mice to be similar to that of lean mice,” Noratto said.

The discovery could help prevent some of the disorders associated with obesity such as low-grade, chronic inflammation that can lead to diabetes. The balance of bacterial communities in the colon of obese people is disturbed. This results in microbial byproducts that lead to inflammation and influence metabolic disorders associated with obesity, Noratto said.

“What determines the balance of bacteria in our colon is the food we consume,” she said.

Re-establishing a healthy balance of bacteria in the colon stabilizes metabolic processes that influence inflammation and the sensation of feeling satisfied, or satiety, she said.

Study shows Vitamin E and Selenium don’t cut colon cancer risk

As one of the former big proponents of Vitamin E, I was disappointed to learn that it does not have all of the healthy impacts I had heard. I just ran across this information that came out a few days ago.

Eight years ago, results from a landmark cancer prevention trial run by SWOG, a National Cancer Institute supported organization, showed that a daily dose of vitamin E and selenium did not prevent prostate cancer. In fact, the Selenium and Vitamin E Cancer Prevention Trial (SELECT) showed that vitamin E supplementation increased the risk of prostate cancer in healthy men.

Nuts and avocados are natural sources of Vitamin E

Now, a SWOG review of ancillary SELECT results definitively shows that these two antioxidants also don’t prevent colorectal adenomas – polyps that are the premalignant precursors to most colorectal cancers. Results are published in Cancer Prevention Research.

“The message to the public is this: Vitamin E and selenium will not prevent colorectal adenomas, which are surrogates for colorectal cancer,” said Dr. Peter Lance, lead author of the journal article and deputy director of the University of Arizona Cancer Center. “We have no evidence that these supplements work to prevent cancer.”

Despite the billions spent in the United States each year on vitamin supplements, there is scant evidence they prevent cancer. According to the National Cancer Institute, which funds SWOG through its National Clinical Trials Network (NCTN) and NCI Community Oncology Research Program (NCORP), results from nine randomized trials did not provide evidence that antioxidant supplements are beneficial in primary cancer prevention. An in-depth review conducted for the United States Preventive Services Task Force likewise found no clear evidence of benefit. Continue reading

Why Drink Water First Thing in the Morning? – Infographic

Regular readers know that I am in my third week of recovering from skin cancer surgery, face and back. I was visiting with a friend of mine and mentioned that since the operations, I had no energy and had actually been napping one to two hours a day. He said that he had heard on CNN a good way to increase your energy was to start the day drinking a glass of Water because a full night’s sleep is a dehydrating experience. That sounded interesting to me and I have been reading about it. This infographic is the beginning of that reading.
