Discover something fishy.
There’s a reason why omega-3 fatty acids are one of the core nutrients. Considered “essential” because the body does not produce them naturally, omega-3s boast a number of health benefits, including helping to reduce the risk of type 2 diabetes.
A study by the University of Eastern Finland found that men with the highest intake of omega-3 fatty acids had a 33% reduced risk for this type of diabetes, compared to men with the lowest intake. Oily fish like wild salmon, rainbow trout, sardines, and mackerel are among the best sources of omega-3s.
The American Heart Association recommends eating two 3 1/2-ounce servings of fatty fish per week.
Circuit train your belly away.
Aerobic exercise is known to prevent type 2 diabetes, and combining a heart-pumping cardio session with muscle-strengthening exercises is even better. A study published in the journal PLOS Medicine found that women who engaged in at least 150 minutes per week (about 20 minutes per day) of aerobic activity and at least 60 minutes per week (three 20-minute sessions) of muscle-strengthening activities reduced their risk of diabetes by 33% compared with inactive women.
Get your Greek on.
A Mediterranean diet may help to guard against obesity and consequently reduce your risk of diabetes by up to 21%, according to research presented at the American College of Cardiology’s 63rd Annual Scientific Session. The researchers’ conclusion comes from the analysis of nineteen original research studies that followed more than 162,000 participants for an average of five and a half years. While there is no set Mediterranean diet, it commonly emphasizes fresh fruits and vegetables, beans, nuts, fish, olive oil and even a regular glass of red wine.
Hit the trail mix.
A study at the University of North Carolina at Chapel Hill found that people who consumed the most magnesium from foods and from vitamin supplements were about half as likely to develop diabetes over the next 20 years as people who took in the least magnesium.
Large clinical trials testing the effects of magnesium on diabetes risk are needed to determine whether a causal relationship truly exists, but researchers have found that as magnesium intake rose, levels of several markers of inflammation decreased, as did resistance to the effects of the key blood-sugar-regulating hormone insulin. Higher blood levels of magnesium also were linked to a lower degree of insulin resistance.
So what should you stock up on? Pumpkin seeds and dark chocolate are two of the best food sources of magnesium.
Eat the whole thing.
Simply choose a whole apple instead of a glass of apple juice, and not only will you dodge a ton of added sugar and additives, but you may also lower your risk for diabetes, according to a study by the Harvard School of Public Health. Researchers found that people who ate at least two servings each week of certain whole fruits—particularly blueberries, grapes, and apples—reduced their risk for type 2 diabetes by as much as 23% in comparison to those who ate less than one serving per month.
Conversely, those who consumed one or more servings of fruit juice each day increased their risk of developing type 2 diabetes by as much as 21%. Swapping three glasses of juice a week with three servings of whole fruit was associated with a 7% risk reduction! The high glycemic index of fruit juice—which passes through the digestive system more rapidly than fiber-rich fruit—may explain the results.
Give red meat the red light.
Bad news for people who love going back for seconds at the barbecue: researchers at the University of Singapore found that a small increase in red meat (we’re talking half a serving per day) was associated with a 48% elevated risk for type 2 diabetes over the course of four years. The good news is that you can undo some of the damage by reducing your red meat intake. (And for more help getting you lean for life, try out this 14-day flat belly plan.)
