Low Melatonin Linked to Diabetes

Melatonin is a hormone most commonly linked to sleep and the body's biological clock; melatonin receptors are found throughout the body, including in the islet cells of the pancreas, which produce insulin. Previous studies suggest that loss-of-function mutations in the melatonin receptor are associated with insulin resistance and type 2 diabetes. Claran McMullan, from Harvard School of Public Health (Massachusetts, USA), and colleagues  reviewed data from the U.S. Nurses' Health Study. The researchers found 370 women who developed type 2 diabetes during the study period, from 2000 to 2012. They also selected 370 women without diabetes for comparison. Melatonin levels were obtained through urine samples. When researchers compared women with the lowest levels of melatonin to those with the highest, they found that low levels increased the risk of developing type 2 diabetes by 2.17 times.  This association held true even after the researchers controlled for other risk factors for type 2 diabetes, such as body weight and dietary habits. Writing that: “Lower melatonin secretion was independently associated with a higher risk of developing type 2 diabetes,” the study authors submit that: “Further research is warranted to assess if melatonin secretion is a modifiable risk factor for diabetes within the general population.”

Tip #153 - Fit with Fiber
Soluble fiber is found in foods such as oat/oat bran, dried beans and peas, nuts, barley, flax seed, fruits such as oranges and apples, vegetables such as carrots, and psyllium husk. It binds with fatty acids and prolongs stomach emptying time so that sugar is released and absorbed more slowly. Researchers from Hospital Universitari de Sant Joan (Spain) randomly assigned 200 overweight or obese study subjects to receive a daily soluble fiber supplement (comprised of Plantago ovata husk and glucomannan) two or three times a day, or placebo, for 16 weeks. At the end of the study, weight loss was higher in both fiber groups (4.52 and 4.60 kg lost, respectively), compared to the placebo group (0.79 kg weight loss). Additionally, LDL (low-density, “bad”) cholesterol levels decreased by 0.38 and 0.24 mmol/l in the fiber-supplemented groups, and the ratio of total cholesterol to HDL (high-density, “good")-cholesterol, and HDL to LDL, were also improved.

The recommended intake of fiber is 25 grams per day. To meet this, eat at least 5 servings of fruits & vegetables as well as at least 6 servings of grain products per day (at least 3 of which are whole grains). Your waistline, as well as cardiovascular health, will both benefit.
