Holding on to brain function through nutrition

By the year 2050, the number of people in the world over 80 years old will reach 370 million. About 50 percent of adults currently 85 and older have Alzheimer’s disease. The statistics are sobering and warn of a growing and serious epidemic. A high prevalence of Alzheimer’s disease, which is a debilitating and costlyContinue reading “Holding on to brain function through nutrition”

How to fight "job-esity"

Workplace programs are an effective and worthwhile way for employers to help improve the health of their employees and reduce medical costs, scientists said Tuesday at Experimental Biology 2012 in San Diego at a session organized by the American Society for Nutrition.  The medical expenses for employees who are obese are estimated at about 42 percentContinue reading “How to fight "job-esity"”

The future of nutrition research

There is little question that nutrition provides the foundation of health and wellbeing and that research into better nutrition is central to enabling a population live healthier, more productive, and longer lives. With this perspective in mind, the American Society for Nutrition assembled a working group of leading nutrition thought leaders to identify a listContinue reading “The future of nutrition research”

A way forward: Meeting vitamin and mineral needs globally

Efforts to curb or eliminate vitamin and mineral deficiencies globally have existed for almost a century, although there are now still as many questions if not more than ever before about what the next steps should be. There are seldom solutions that are simple to guide public policy internationally and there remain large challenges whenContinue reading “A way forward: Meeting vitamin and mineral needs globally”

Sugar Showdown: Science Responds to "Fructophobia"

The scientific community lashed out against “sugar is toxic” sensationalism on Sunday, April 22, identifying it as a distraction from more meaningful areas of research and debate on the causes of obesity and disease. In a highly attended debate at Experimental Biology 2012 in San Diego sponsored by the Corn Refiners Association, scientists expressed clearContinue reading “Sugar Showdown: Science Responds to "Fructophobia"”

Beyond calories in, calories out — look to the Amish

What is wrong with “eat less, move more”? Most of us are familiar with this mantra as weight-loss advice. However, a new consensus statement from the American Society for Nutrition (ASN) and the International Life Sciences Institute (ILSI) contends that this energy-in-energy-out framework isn’t really so simple. The problem lies in that consuming fewer caloriesContinue reading “Beyond calories in, calories out — look to the Amish”

Can carotenoids in the brain protect against Alzheimer’s?

Carotenoids are thought to protect against Alzheimer’s disease because of their antioxidant properties and their accumulation in the brain. However, a new study from Tufts University is putting the theory into question. More than a century has passed since the German physician Dr. Alois Alzheimer first presented evidence on the case of Auguste Deter, whoContinue reading “Can carotenoids in the brain protect against Alzheimer’s?”

Could how much and often people eat depend on their genes?

Thanks to the Human Genome Project, we humans now know that we are all really very much the same at the level of our DNA. Our genomes are 99.9 percent identical, leaving really only 0.1 percent responsible for giving each of us what we would consider our differences or unique qualities. It’s within this 0.1Continue reading “Could how much and often people eat depend on their genes?”

New and old tools of science communications

Sci-comm thrives on social media.  “Writing is thinking on paper” is one of the many beautiful phrases by William Zinsser, author of On Writing Well. Only, if Zinsser had put those words down more than three decades later, he might have added that writing is also thinking on blogs, Twitter, Facebook, and Google+. As IContinue reading “New and old tools of science communications”

No, Dr. Gupta, hummingbird fuel is not "toxic"

Sugar is toxic? Not this hummingbird’s opinion. Whenever someone asks me whether or not sugar or high-fructose corn syrup is “toxic,” I remind them that every few days I make up a simple solution of four parts boiled water and one part plain white table sugar. This I use to fill the hummingbird feeders inContinue reading “No, Dr. Gupta, hummingbird fuel is not "toxic"”
