  • Study Suggest Diets Should Be Personally Tailored, Given How Individual Gut Microbiomes Impact Glycemic Response
    A study from Israel's Weizmann Institute of Science revealed that people given identical meals metabolize them very differently, because their individual gut microbiome impacts the glycemic response. An individual's gut bacteria was found to be a key factor in influencing whether a food delivers a long, slow rise in blood sugar, or a short, sharp spike. And if one would expect higher blood sugar spikes from eating ice cream than from eating rice, for a significant number of study participants, the reverse was true. The study suggests that diets should be personally tailored, using personal and microbiome features to enable accurate glucose response prediction.

  • Insurers Find Success with MNT
    A study of 4,000 overweight/obese patients found that those who participated in medical nutrition therapy (MNT) via their insurer were twice as likely to achieve significant weight loss. They experienced greater mean reductions in weight (3.1 vs. 1.4 kg) and BMI (1.1 vs. 0.4 points), and were more likely to exercise more frequently after the program. The conclusion: MNT is relatively low cost, and warrants serious consideration as a standard inclusion in health benefit plans.

  • Denmark Study Compares Outcomes: Doctors vs Dieticians
    A Glostrup University Hospital (Denmark) randomized trial (involving 60 doctors and 339 patients) - comparing the effectiveness of nutritional counseling from a doctor (GP) vs. a dietician - found that weight loss was greater in the dietician group, while the reduction of cardiovascular risk scores was higher for GP group, and for obese patients, long-term nutritional counseling by a dietician was superior.
