Nutrition Science Is Broken. This New Egg Study Shows Why.

Timothy F. Kirn, writing for Undark:

This March, a study published in JAMA put the egg back on the hot seat. It found that the amount of cholesterol in a bit less than two large eggs a day was associated with an increase in a person’s risk of cardiovascular disease and death by 17 percent and 18 percent, respectively. The risks grow with every additional half egg. It was a really large study, too — with nearly 30,000 participants — which suggests it should be fairly reliable.

So which is it? Is the egg good or bad? And, while we are on the subject, when so much of what we are told about diet, health, and weight loss is inconsistent and contradictory, can we believe any of it?

This happens with coffee and so many other foods. It’s a wonder anyone still pays attention to news articles about these studies at all.

Athlete vs. Heat

An interesting look by the Washington Post’s Rick Maese at how heat affects athletic performance and what is being done to cope with climate change:

From community races to the Olympics to the World Cup, event organizers are already having to make adjustments to competition schedules and start times. And athletes around the world are having to take more precautions as science and technology evolve to help them cope with the heat — or, in some cases, gain a competitive advantage.

Events such as the Australian Open have instituted safety measures to account for extreme heat. The International Olympic Committee and FIFA have formed committees to study heat-related issues at major events. Next summer’s Olympics in humid Tokyo will feature a marathon that starts at 6 a.m.
