Science News Roundup

While we here at MDA like to pay close attention to our bodies and use common sense to help determine what is and isn’t healthy, actual scientific evidence forms the backbone of our philosophies. We scour breaking health and nutrition news releases to make sure our ideas are supported by science. It’s important, we think, to present a multifaceted case for the Primal Blueprint as the ideal lifestyle choice, because years and years of being barraged by low-fat diets and rabid calorie-counting espoused by “experts” has inured your average person against the PB.

Cranberry Juice and UTIs

cranberriesYou’ve known for years that cranberries can help stave off urinary tract infections (UTIs), but now scientists have figured out the mechanism behind the benefit!

In a study published in this month’s Colloids and Surfaces B: Biointerfaces, researchers from Worcester Polytechnic Institute in Massachusetts analyzed the Gibbs free energy of adhesion changes between bacteria and uroepithelial cells exposed to varying concentrations of cranberry liquids. In English? Essentially, the researchers extracted some cells from the inside of the urinary tract, threw in some bacteria, doused them with cranberry juice and watched to see how they would interact.

A Day in the Life of Modern Grok: An MDA Reader Gets Primal

As a follow up to last week’s Primal Challenge, “Getting Back to Nature,” I thought I’d published a few emails I’ve received from a hardcore Primal Blueprint follower. Talk about getting Primal. This guy is trying it all.

Irradiation: Savvy Safety Mechanism or Band-Aid for a Bigger Problem?

Following the recent tainted spinach controversy, the federal Food and Drug Administration (FDA) last month ruled that food manufacturers can now irradiate fresh spinach and iceberg lettuce to kill bacteria associated with food-borne illnesses.

Huh? Exactly. Essentially food irradiation refers to a process whereby food is exposed briefly to a radiant energy source (usually in the form of a gamma ray or electron beam) that is thought to kill harmful bacteria, thereby reducing the risk of contracting a food-borne disease. The FDA also contends that blasting your food with radiation can reduce the bacteria responsible for spoilage, kill insects and parasites, and delay ripening in certain fruits and vegetables. In fact, while we’re on the topic, it should probably be noted that the concept of irradiating foods is far from new: In 1999, the FDA began reviewing irradiation and has approved its use in meats, certain shell fish, produce, certain egg varieties, flour, spices and unpasteurized fruit juices. These foods, however, must bear an internationally recognizable stamp, known as a radura, to signal that the food has been irradiated.
