Research Spotlight

The databases often return hundreds of medical studies for a single wellness approach. This section summarizes a sampling of five studies – providing just a taste of the available research. These Spotlights were not selected because they are the most favorable or the most recent, but to provide you an introduction to the more extensive research you'll uncover searching the four databases found in the “Research” section of this site.

  • Ordering/Choosing Food Before You Plan to Eat It Means Lower-Calorie Diet
    New Carnegie Mellon University experiments indicate that timing matters when it comes to healthier eating. When a solid gap existed between when people ordered or chose their food and when they planned to eat it, they opted for significantly lower calorie meals.

  • Eating Whole Grains Cuts Risk of Early Death by 17%
    A meta-review of 45 studies from Imperial College London (2016) concluded that eating 90 grams of whole grains a day significantly cut the risk of cancer, coronary heart disease and diabetes. Compared with eating no whole grains, it was associated with cutting the risk of early death by 17%. Current guidelines recommend at least 48 grams of whole grains daily, and a slice of 100% whole grain bread contains about 16.

  • 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.

  • Mediterranean Diet Helps Mitigate Cognitive Decline, Memory Loss
    Results of a first-of-its-kind University of Barcelona (Spain) clinical, randomized study of 477 subjects revealed a slowing of decline in cognitive functions for those who supplemented their diets with nuts and olive oil versus subjects who followed a typical low-fat diet.

  • Nutritional Counseling Improves Diet Behaviors
    A National Institute of Health Research systematic review (29 randomized controlled trials) concludes nutritional counseling improves dietary habits, and more intensive counseling aimed at higher risk patients produces even larger changes in behavior.

  • 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.
