Disconnecting food with how you feel can put you on track to stop emotional eating. You don't need to eat a big cupcake to feel satisfied. A small one will do. Promise.

Topic of Study: Snack portions
Location of study: U.S./Netherlands
Study subjects: 104 adults

Results: A new study co-authored by researchers at Cornell University, published in “Food, Quality and Preference,” found that eating smaller portions of commonly craved snacks is equally as satisfying as eating a larger portion. The study concluded that eating a small portion and waiting 15 minutes before eating more allows for the brain and stomach to register satiety. Study subjects who ate the larger portions of snacks consumed 77 percent more calories, but their cravings abated after 15 minutes, just like the group that ate a smaller portion.

Significance: Researchers concluded that eating for pleasure rather than hunger is not controlled by satiety, but by availability, and that eating uncontrolled portions of snacks contributes to weight gain.


Topic of Study: TV watching and sperm quantity
Location of study: U.S.
Study subjects: 189 men from Rochester, N.Y., between the ages of 18 to 22

Results: A study published in the British Journal of Sports Medicine found that healthy young men who watched television, DVDs or videos for 20 hours or more each week had 44 percent lower sperm count compared to men who watched very little or no TV. The study, which was conducted by Harvard School of Public Health’s Department of Nutrition, also found that men who spent 15 or more hours each week engaged in moderate to vigorous exercise had 73 percent higher sperm counts compared to men who engaged in very little exercise.

Significance: Scientists are studying why semen quality has deteriorated over the past few decades. An increasingly sedentary lifestyle might be a contributory factor.

Topic of Study: Potential pill for celiacs
Location of study: U.S.

Results: The “Journal of the American Chemical Society” recently published a report that the development of a pill to allow celiac disease sufferers to eat gluten is looking promising. The pill, as yet undeveloped, is expected to act something like the lactase pills that people with lactose intolerance take to allow them to digest dairy products. Celiac disease is an autoimmune disorder in which the gluten in wheat, rye or barley products causes inflammation in the digestive tract.

Significance: There is an estimated 2-3 million Americans with celiac disease. The pill, if developed, is expected to break down more than 95 percent of a gluten peptide and enable celiac disease sufferers to eat gluten-containing foods.

Topic of study: Thermometers in ERS
Location of study: India
Study subjects: 50 febrile and 50 afebrile children aged 2-12 years

Results: A report published by “Pediatric Emergency Care” found that temporal artery thermometers (which tell temperature with a swipe across the forehead) had comparable accuracy to rectal thermometers in determining core body temperature. The results were confirmed when used in both patients with or without a high temperature.

Significance: Using temporal artery thermometers is faster and cuts the risk of cross contamination that exists when rectal thermometers are used. The study shows that temporal artery thermometers have the potential to replace rectal thermometers in emergency room settings.
