Soylent powder is better toss

It’s apparently not just Soylent bars making people sick. The company is now warning customers about its signature meal replacement powder, which has been removed from shelves after a “handful” of users reported cases of diarrhea, vomiting, and other stomach issues, just like with its Food Bars.

Though “our tests all came back negative for food pathogens, toxins or outside contamination,” this has “allowed us to shift our focus to whether any one ingredient might be triggering a food intolerance,” the company says in a blog post, per Gizmodo.

Soylent’s products have several ingredients in common, but the company notes its premixed drinks appear to be safe. Soylent says anyone who has consumed version 1.6 of the meal replacement powder without issue can continue, “but if you have had any sensitivities, we suggest discarding whatever is left and letting us know.” The powder ($54 for the equivalent of 28 meals) has found a following among busy Silicon Valley types, and at least some are still willing to stick by the company, per the Los Angeles Times.

In fact, many online are upset that they won’t be able to buy more Soylent products for a while. Soylent, however, is already working on a new powder and bar that it says won’t include suspect ingredients, to be available by early 2017 at the latest.

How to make exercise easier to take

unduhan-5High-intensity interval training is all the rage, with research suggesting that just a few minutes of all-out sweating could reap the same health benefits as a 45-minute moderate workout, and that’s true even for the elderly.

The draw is clear—interval training takes less time, after all—but so is the drawback, as the New York Times reports: Pushing ourselves with such intensity even in short bursts can be grueling.

But new research out of McMaster University in Ontario suggests that while it’s hard, HIIT might not be all that unpleasant, and that when people listen to music while pushing hard, they rather like it.

“This research tells us that they can actually enjoy it, and they may be more likely to participate in HIIT again if they try it with music,” says one researcher, per Psych Central

Reporting in the Journal of Sports Sciences, researchers say they studied 20 young, healthy, and physically active men and women performing HIIT for the first time in two scenarios—one without music, and one with—and that each session was followed an hour later by questionnaires.

The volunteers rode stationary bikes, starting with an easy two-minute warmup before four 30-second bursts of all-out pedaling. Turns out that on a scale of 1 to 7, where 7 is “I loved it,” most ranked the exercise a 5, but their ratings climbed to 6 after they did the training to music.

The tunes also made them more likely to continue with the training. Whether these findings would translate to a larger group of people who are more sedentary remains unclear.

Breast cancer risks

Women are becoming more aware of the term “breast density,” but they aren’t as familiar with its relation to breast cancer risk or mammograms, according to a small U.S. study.

In particular, African American and Ashkenazi Jewish women, who may be at a higher risk for breast cancer, seemed to be less knowledgeable about breast density, researchers found.

“There’s a national movement to increase women’s awareness of breast density and help them make better healthcare decisions,” said Jennifer Harvey, study author and co-director of the University of Virginia Breast Care Program in Charlottesville, Virginia.

“Although women are more aware of this topic, they don’t understand the implications of what having dense breasts means,” she told Reuters Health. “It can be really common.”

Breast density compares the amount of fat to the amount of other types of tissue in a mammogram image. Dense breasts contain more glandular and fibrous tissue than fatty tissue. Typically, breast density decreases as women age.

Previous studies have found that breast density reduces the sensitivity of mammography because there is more tissue to scan and study. In addition, density is considered an independent risk factor for breast cancer due to increased estrogen production, genetic heredity and elevated growth factors in the breast tissue of women with dense breasts, according to Harvey.
