Our Microbiome May Be Looking Out for Itself

Your body is home to about 100 trillion bacteria and other microbes, collectively known as your microbiome. Naturalists first became aware of our invisible lodgers in the 1600s, but it wasn’t until the past few years that we’ve become really familiar with them. This recent research has given the microbiome a cuddly kind of fame. We’ve come to appreciate how beneficial our microbes are — breaking down our food, fighting off infections and nurturing our immune system. It’s a lovely, invisible garden we should be tending for our own well-being. But in the journal Bioessays, a team of scientists has raised a creepier possibility. Perhaps our menagerie of germs is also influencing our behavior in order to advance its own evolutionary success — giving us cravings for certain foods, for example.
Maybe the microbiome is our puppet master.

Punished by Reward

Neurobiologist Stephan Guyenet provides two video introductions to his intriguing hypothesis about the cause of obesity: frequently eating highly palatable processed foods (foods with high "reward" effect in the brain) alters the hypothalamus, raising the body's homeostatic set point. [more inside]

291 diseases and injuries + 67 risk factors + 1,160 non-fatal complications = 650 million estimates of how we age, sicken, and die

As humans live longer, what ails us isn't necessarily what kills us: five data visualizations of how we age, sicken, and die. Causes of death by age, sex, region, and year. Heat map of leading causes and risks by region. Changes in leading causes and risks between 1990 and 2010. Healthy years lost to disability vs. life expectancy in 1990 and 2010. Uncertainties of causes and risks. From the team for the massive Institute for Health Metrics and Evaluation Global Burden of Diseases, Injuries, and Risk Factors Study 2010. [more inside]

Fat: The Gift that Keeps On Giving

The Fat Trap (NYT pop review): Overweight individuals in Western nations (and, increasingly, beyond) face interpersonal and institutional stigma for their bodies*. Oftentimes, these stigmas are predicated on the belief that being overweight is a moral failure, that being overweight is usually a result of laziness, decadence, and/or characterlogical poor impulse control. However, an emerging consensus among obesity researchers points toward strong, common physiological and individual genetic factors as causative for heightened BMIs in the modern world and the general failure of dieting to produce BMI outcomes. A recent study in the New England Journal of Medicine (paywalled) adds to this body of evidence, suggesting that chemical messengers held to contribute to altered "efficient" metabolism and increased hunger in the wake of low-calorie dieting are (on average) significantly elevated up to a full year (if not longer) following a substantial drop in weight from dieting.

The Sixth Sense of Taste

Sweet, sour, bitter, salty, umami, and.... fat? Dr. Russell Keast, an Austrailian scientist who studies "perceived flavour, consumer acceptance and preference of foods and nutrition," has conducted research exploring humans' apparent sixth taste perception: fat. The kicker? Sensitivity to the taste of fat was negatively correlated with fat intake and BMI. Dr. Keast discussed the results of his latest research with Slashfood, and The Sydney Morning Herald.
