Get clued up on nutrition
1 Pungent Protection
Garlic supplements may be almost as good as prescription meds at lowering blood pressure, according to an Australian study. When the scientists reviewed 11 studies, they determined that people who took between 600 and 900mg garlic powder daily reduced their systolic blood pressure by five points. Don’t want to take a pill? Drop some extra garlic in your meal. “One clove of raw garlic contains an amount of allicin similar to a supplement’s,” says study author Dr Karin Ried.
2 Time To Take Stalk
Vegetables are well known for their cancer-fighting potential. Now British researchers have discovered that eating broccoli could shield you from the wrath of diabetes. In a test-tube study, the scientists found that sulforaphane, a chemical derived from cruciferous vegetables, switches on genes that produce enzymes that protect your blood vessels from the damage linked to high levels of blood glucose. The compound also appears to increase levels of disease-fighting antioxidants, which do battle with the free radicals created by raging blood sugar
3 Doctors and Diets
There’s a good chance your physician isn’t an expert on your dietary needs. According to a study from New York University, only three percent of medical students surveyed took a nutrition elective and 46 percent didn’t know how many kilojoules are in a gram of protein. (The answer is four.) Our advice: if your doctor’s prescription includes a change in diet, ask for a referral to a nutritionist whose specialty matches your needs.
4 Watch The Mercury Drop
The next time you belly up to the sushi bar, have a cup of ocha (Japanese green tea), too. That’s because drinking tea may block the toxins in seafood from entering your blood, according to Purdue University researchers. The scientists found that when mackerel was combined with tea extract, the amount of mercury absorbed from the fish was reduced by up to 92 percent. Catechins in tea may react with mercury to create new compounds that can’t be absorbed into the body during digestion, say the researchers. Sip either green or black tea with your fish: both showed nearly identical effects.
5 Love Your Liver
Not only will gorging on sugar and starch expand your waistline, but eating too many carbohydrates may harm your liver, too, report Duke University researchers. That’s because excess blood sugar is converted to fat in your liver, where it can accumulate and lead to non-alcoholic fatty liver disease, says study author Dr Eric Westman. Fortunately, the scientists found that patients who adhered to low-carb diets not only lost weight but reversed their condition in six months. You’re most at risk if you have fasting blood glucose greater than 8mmol/l, indicating that your body doesn’t process carbs well.
