Pauline Maddox reviewed 15 trials using one to six grams of cinnamon daily: six showed significantly lower HbA1c and 10 lower fasting glucose. She concludes cinnamon can be recommended, though cassia cinnamon carries coumarin, which can harm the liver at high or prolonged doses.

Supplements
Many natural weight loss pills are adulterated with drugs
Researchers testing 160 “100% natural” weight loss supplements bought online found 56% contained at least one of six prescription drug ingredients, most often sibutramine and phenolphthalein. Some drugs detected were withdrawn years ago because of toxicity.
Herbs
Dandelion root extract fights cancer
University of Windsor researchers led by Siyaram Pandey report that dandelion root extract kills drug-resistant human melanoma cells without apparent harm to healthy cells, and that a water extract was active against leukemia, pancreatic and colon cancer cells.
Diet
Mediterranean diet lowers risk of hip fractures
A study in JAMA Internal Medicine found postmenopausal women who ate a Mediterranean diet were 20 percent less likely to suffer hip fractures than women who did not follow it.
Food
Cranberry Juice Can Boost Heart Health
Over eight weeks, 56 volunteers drinking low-calorie cranberry juice twice a day ended with lower levels of 5 of 22 cardiometabolic risk indicators than volunteers given a flavor-matched placebo. Ocean Spray funded the study and supplied the juice but did not run or analyse it.
Minerals
Magnesium and Health: The Whole Truth About These Supplements
A beginner's guide from LabDoor's Benita Lee: magnesium is needed to make DNA, RNA, protein and glutathione, moves calcium and potassium across cell membranes for nerve impulses, muscle contraction and heart rhythm, and supports insulin regulation and blood glucose control.
Food
Lowering the Risk of Infection with Grapes
In a USDA crossover study, obese participants drank freeze-dried grape powder in water or a placebo twice daily for three weeks, then switched. ARS molecular biologist Susan Zunino reports grape phytochemicals may cut certain blood fats tied to heart disease and lower infection risk.

Type 2 diabetes mellitus risk lower in black coffee drinkers
Among 3,497 Korean patients with prediabetes followed up to four years, progression to type 2 diabetes was lowest in those drinking black coffee three times a day. None of these studies are trials, so whether coffee itself prevents diabetes remains unclear.
Herbs
Chamomile tea helps diabetes mellitus
A commentary in the Journal of Diabetes & Metabolism argues that drinking chamomile tea right after meals may help control blood sugar, citing a randomized trial and animal work suggesting it slows hyperglycemia and diabetic complications. It is one author's reading of the evidence.
Diet
Mediterranean diet helps type 2 diabetes mellitus
In the MeDITA randomized trial, people newly diagnosed with type 2 diabetes who followed a Mediterranean diet for a year had lower C-reactive protein and higher adiponectin than those on a low-fat diet, which the researchers read as reduced inflammation alongside some fat loss.

What to eat on St Patrick's Day (March 17, 2016)
Abbott Nutrition suggests five green foods for St. Patrick's Day: green tea for antioxidants such as EGCG, spirulina for protein and micronutrients, kiwi for vitamin C, edamame for protein, and spinach for vitamins A, B6 and C plus calcium, iron and potassium.
Vitamins
Why Your Body Needs Multivitamins
An argument that most people should take a multivitamin even while eating well, with advice to build meals around fruits, nuts, vegetables, whole grains and healthy oils, and notes that pregnant women, children, older adults and vegetarians have differing needs.
Supplements
Omega 3 fatty acids EPA, DHA help depression
In a secondary analysis of a placebo-controlled trial, depressed patients who remitted after EPA and DHA supplementation carried higher red blood cell levels of both fatty acids than those who did not. Everyone took sertraline; only the treatment group received 930 mg EPA and 750 mg DHA daily.
Supplements
Fish oil helps nonsmall cell lung cancer
In a study in Cancer, advanced non-small cell lung cancer patients who took 2.5 g of EPA plus DHA daily alongside chemotherapy had a 60% response rate against 26% for controls, and 60% one-year survival against 39%. The supplements appeared safe.
Food
Cranberry Compound May Help Prevent Urinary Tract Infections
USDA Agricultural Research Service scientists and collaborators purified a compound they call the SSGG fraction from enzyme-treated cranberry pulp. In laboratory tests it kept E. coli, the most common cause of UTIs, from sticking to human cells. The work was supported by Ocean Spray.
Vitamins
Vitamin D cuts colorectal cancer risk
A case-control study in Gut led by Harvard's Shuji Ogino linked high plasma 25(OH)D to 90% lower colorectal cancer risk, but only in people whose tumors showed a strong intratumoural periglandular immune reaction, not in those with a weaker response.
Nutrition
Hitting the Sweet Spot in the Dietary Guidelines for Americans
A commentary walks through the arithmetic the Dietary Guidelines require to keep added sugars under 10 percent of calories: total the day's calories, take 10 percent, then divide by 4 for grams or 16 for teaspoons. The shortcuts the Guidelines offer are vaguer and less accurate, the writer says.
Food
Dietary protein, some amino acids increase bone mineral density
A Journal of Bone and Mineral Research study of 135 twin pairs linked higher alanine and glycine intake in women to higher spine bone mineral density, and an analysis of 3,160 women aged 18 to 79 tied protein and six amino acids to higher density at the spine and forearm.
