While exercise buffs have long used protein supplements to gain muscle, new research from McMaster University suggests one protein source in particular, whey protein, is most effective for seniors struggling to rebuild muscle lost from inactivity associated with illness or long hospital stays.

The proportion who developed type 2 diabetes was lowest in the group which reported the highest wholegrain consumption, and increased for each group which had eaten less wholegrain. In the group with the highest wholegrain intake, the diabetes risk was 34 percent lower for men, and 22 percent lower for women, than in the group with the lowest wholegrain intake.
“It is unusual to be able to investigate such a large range when it comes to how much wholegrain people eat,” says Rikard Landberg. “If you divided American participants into 4 groups, the group that ate the most wholegrain would be the same level as the group that ate the least wholegrain in Denmark. In Europe, Scandinavia eats the most, Spain and Italy the least.”
Additionally, the study was uncommonly large, with 55,000 participants, over a long time span — 15 years.

This study prospectively examined the relationship between low carbohydrate diets, all-cause death, and deaths from coronary heart disease, cerebrovascular disease (including stroke), and cancer in a nationally representative sample of 24,825 participants of the US National Health and Nutrition Examination Survey (NHANES) during 1999 to 2010. Compared to participants with the highest carbohydrate consumption, those with the lowest intake had a 32% higher risk of all-cause death over an average 6.4-year follow-up. In addition, risks of death from coronary heart disease, cerebrovascular disease, and cancer were increased by 51%, 50%, and 35%, respectively.
The results were confirmed in a meta-analysis of seven prospective cohort studies with 447,506 participants and an average follow-up 15.6 years, which found 15%, 13%, and 8% increased risks in total, cardiovascular, and cancer mortality with low (compared to high) carbohydrate diets.

The scientists randomly divided 292 male mice into two diet groups. One group received a naturally sourced diet that was lower in purified sugars and fat, and higher in protein and fiber than the other diet. The mice in each diet group were then divided into three sub-groups based on how often they had access to food. The first group of mice had access to food around the clock. A second group of mice was fed 30 percent less calories per day than the first group. The third group was meal fed, getting a single meal that added up to the exact number of calories as the round-the-clock group. Both the meal-fed and calorie-restricted mice learned to eat quickly when food was available, resulting in longer daily fasting periods for both groups.
The scientists tracked the mice’s metabolic health through their lifespans until their natural deaths and examined them post-mortem. Meal-fed and calorie-restricted mice showed improvements in overall health, as evidenced by delays in common age-related damage to the liver and other organs, and extended longevity. The calorie-restricted mice also showed significant improvement in fasting glucose and insulin levels compared to the other groups. Interestingly, the researchers found that diet composition had no significant impact on lifespan in the meal fed and calorie restricted groups.
One of my neighbors is a mouse researcher. I bet he’s really excited this weekend.

if one observes a benefit in a population associated with consuming a food or beverage, and the benefit is not mediated by the active ingredient in that food or beverage, the finding is likely due to unmeasured confounding. In other words, I think coffee is in the same camp as red wine: the observed benefits are likely due more to the type of person who drinks it than what’s actually in the drink.

Adopting a vegetarian or semi-vegetarian diet to lose weight and improve health may not be as onerous as is typically assumed, as people can experience health benefits even if they only partially switch to plant-based foods. In addition, the diets may cost less than other healthy diets, suggests new research presented here at the European Congress on Obesity (ECO) 2018.

The team focused on a protein called p27, which is known among other things to influence the cell cycle. The team found that caffeine triggered the movement of p27 into the mitochondria of heart cells in mice, and in particular, the migration of the heart’s endothelial cells, which line the blood vessels. How well the endothelial cells were able to migrate, they found, relied strongly on the presence of p27, which again is bolstered by caffeine.

We present some top-line findings from these studies below. When reading these summaries, it is important to bear in mind that while the abstracts presented at Nutrition 2018 were evaluated and selected by a committee of experts, the papers have not undergone the same rigorous standard of peer review that is applied to scientific journals.
So, we should consider these findings as “preliminary results,” until they are properly assessed.

I find surveys like this amusing. Interview 1000 people and extrapolate the findings to all Americans. The click bait title is great too. It’s so misleading I had to copy it verbatim.
