Metabolic Effects of Monounsaturated Fatty Acid-Enriched Diets Compared With Carbohydrate or Polyunsaturated Fatty Acid-Enriched Diets in Patients With Type 2 Diabetes: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

This meta-analysis of observational studies concluded that eating diets high in monounsaturated fatty acids may improve risk factors for metabolic disorders among people with type 2 diabetes.

Metabolically healthy obesity is associated with an increased risk of diabetes independently of nonalcoholic fatty liver disease.

Some obese people do not have any signs of metabolic disorders, even though they may have a large waist circumference. This type of obesity is sometimes called metabolically healthy obesity (MHO).

This prospective observational study showed that people who were MHO in the beginning were at an increased risk of developing type 2 diabetes later on, regardless of whether they had a fatty liver.

Frequent Consumption of Sugar- and Artificially Sweetened Beverages and Natural and Bottled Fruit Juices Is Associated with an Increased Risk of Metabolic Syndrome in a Mediterranean Population at High Cardiovascular Disease Risk.

This observational study suggests that drinking more than five servings of sugar-sweetened beverages or bottled fruit juices per week is linked to an increased risk of metabolic syndrome.

Serum calcium and incident type 2 diabetes: the Atherosclerosis Risk in Communities (ARIC) study.

Previous studies suggest that elevated circulating levels of calcium are associated with metabolic disorders, including type 2 diabetes.

This observational study in 12,800 adults supports previous findings, showing that high calcium levels were linked to an increased risk of type 2 diabetes.

Zinc status, dietary zinc intake and metabolic risk in Australian children and adolescents; Nepean Longitudinal Study.

This observational study in Australian children and adolescents showed that those who had low circulating zinc levels were at a greater risk of elevated insulin (at 15 years old) and blood sugar (at 8 years old).

Therapeutic potential of green tea on risk factors for type 2 diabetes in obese adults – a review.

This review discussed the effectiveness of green tea and green tea antioxidants, such as epigallocatechin gallate, at treating type 2 diabetes, obesity and metabolic disorders.

The authors concluded that although green tea could potentially treat type 2 diabetes and obesity, further studies are needed before any strong claims can be made.

The Effects of Soy Isoflavones on Metabolic Status of Patients With Polycystic Ovary Syndrome.

Isoflavones are a class of polyphenol antioxidants found in soybeans. This randomized controlled trial in 70 women with polycystic ovary syndrome examined the health effects of supplementing with 50 mg of isoflavones per day for 3 months.

The study showed that supplementing with isoflavones improved markers of insulin resistance and oxidative stress. It also improved the blood lipid profile (triglyceride levels) and hormonal status.


Effect of vitamin D replacement on indexes of insulin resistance in overweight elderly individuals: a randomized controlled trial.

This randomized controlled trial in overweight, elderly people (69% with prediabetes) showed that supplementing with 600 or 3,750 IU of vitamin D per day did not improve insulin resistance.

Vitamin D supplementation reduces insulin resistance in Japanese adults: a secondary analysis of a double-blind, randomized, placebo-controlled trial.

This randomized controlled trial in healthy Japanese adults showed that supplementing with 420 IU of vitamin D per day for one year significantly reduced fasting blood sugar levels and insulin resistance.

Meat Consumption and Risk of Developing Type 2 Diabetes in the SUN Project: A Highly Educated Middle-Class Population.

Previous observational studies indicate that high meat consumption may increase the risk of type 2 diabetes (T2D).

This observational study supports earlier evidence. It showed that meat consumption, especially processed meat, was associated with an increased risk of developing T2D.

Effects of a Multispecies Probiotic Mixture on Glycemic Control and Inflammatory Status in Women with Gestational Diabetes: A Randomized Controlled Clinical Trial.

This randomized controlled trial in women with diabetes during pregnancy examined the health effects of supplementing with a multispecies probiotic mixture for 8 weeks.

Taking probiotics led to a significant decrease in several inflammatory markers. Additionally, insulin levels and insulin sensitivity was improved in the probiotic group, compared to the placebo.

Polyphenol- and fibre-rich dried fruits with green tea attenuate starch-derived postprandial blood glucose and insulin: a randomised, controlled, single-blind, cross-over intervention.

High amounts of fiber or polyphenol antioxidants generally improve blood sugar control after a meal. They partly work by inhibiting digestive enzymes and slowing the absorption of sugar/carbs.

This randomized controlled trial supports previous studies showing that adding fiber and polyphenols to starch significantly lowered post-meal rises in blood sugar and insulin.

Consumption of soy foods and isoflavones and risk of type 2 diabetes: a pooled analysis of three US cohorts.

Isoflavonoids, or isoflavones, are plant compounds found in legumes, especially soybeans.

This observational study found that dietary intake of isoflavones was linked to a slightly lower risk of type 2 diabetes in US men and women who generally ate low or moderate amounts of soy foods.

Dietary supplementation with omega-3 fatty acids and oleate enhances exercise training effects in patients with metabolic syndrome.

This was a randomized controlled trial in people with metabolic syndrome on a 24-week, high-intensity exercise program.

The study showed that drinking skim milk enriched with 275 mg of omega-3 fat and 7.5 grams of oleate improved insulin sensitivity, reduced inflammation (CRP levels) and increased HDL-cholesterol levels, compared to a placebo.

Curcumin and insulin resistance—Molecular targets and clinical evidences.

Curcumin is the main active ingredient in turmeric, a popular Indian spice. Supplementing with curcumin may have various health benefits. However, research on the effects of curcumin on insulin resistance has provided inconclusive results.

Different doses, treatment times and types of curcumin supplements may affect study results. This review discussed the available evidence and how to improve the potential benefits of curcumin on blood sugar control.

Plant-Based Dietary Patterns and Incidence of Type 2 Diabetes in US Men and Women: Results from Three Prospective Cohort Studies.

This observational study in women from the Nurses’ Health Study indicates that plant-based diets may reduce the risk of type 2 diabetes. This especially applied to whole, unprocessed plant foods.

Vitamin D3-Supplemented Yogurt Drink Improves Insulin Resistance and Lipid Profiles in Women with Gestational Diabetes Mellitus: A Randomized Double Blinded Clinical Trial.

This was a 16-week, randomized controlled trial in women with diabetes during pregnancy. It showed that eating yogurt enriched with vitamin D3 significantly improved insulin sensitivity and blood lipid profiles, compared to plain yogurt.
