Hold the resveratrol
There is such thing as too much of the world’s hottest anti-ageing antioxidant.
Resveratrol could block the cardiovascular benefits of exercise over a certain dosage threshold, according to research published in The Journal of Physiology.
The anti-found in red wine blocks the blood pressure and cholesterol-lowering clout when dosage reaches 250 mg, University of Copenhagen researchers found. How? Healthy responses to stresses like exercise rely on reactive oxygen species involved in ageing and wiped out by excess resveratrol, researchers suggested. That’s not to say there’s no merit in a glass of merlot, which contains less than three mg.

DEEP FREEZE
It’ll save you seven minutes, but that’s where the good news ends for frozen broccoli.
According to University of Illinois researchers, fro-bro is unable to form cancer-fighting phytochemical sulforaphane found in fresh broccoli.
 The heat used to blanch the veg before its bagged retards enzyme myrosinase, a precursor to sulforaphane, researchers found.
But you can square the ledger by sprinkling broccoli with a bit of raw radish, cabbage, spicy mustard or wasabi.
GOOD TO KNOW:
Sulforaphane is formed when fresh broccoli is chopped or chewed.




BRAIN FOOD BETTER BAKED
Frying can turn fish fingers toxic, with pan cooking producing two to three times the furanic compounds as oven cooking. Frying in olive oil yields three times more potentially carcinogenic furans than baking while sunflower oil nets twice the furans, found research published in journal Food and Chemical Toxicology.
SAFETY SHEET: To reduce furans, keep frying temperature and time to 160 degrees and four minutes, and leave at least 10 minutes between frying and eating. Hot tip: reheating in the microwave brings furans down to below baked levels.



18%
THAT'S HOW MUCH DEMENTIA RISK INCREASED IN NON-DIABETICS WITH AN AVERAGE GLUCOSE LEVEL OF 115 MG PER DECILITRE THAN IN THOSE WITH A GLUCOSE READING OF 100, A STUDY PUBLISHED IN THE NEW ENGLAND JOURNAL OF MEDICINE FOUND. BUT RESEARCHERS SAID IT WASN’T A PROMPT TO CUT SUGAR OR GO LOW GI BECAUSE
BLOOD SUGAR LEVELS DEPEND NOT ONLY ON WHAT YOU EAT BUT ON HOW YOUR BODY HANDLES THAT FOOD. WALKING WAS A WORTHY
INTERVENTION, THEY SAID.



MEGA MEMORY BITES
MEGA MEMORY BITES  If only boosting your own memory was as simple as plugging in a bigger USB. New research says it might be. Vitamin B-group nutrient choline – found in eggs, chicken and beef liver, soy and wheat germ – was shown to improve long-term memory and attention-holding capacity in an experimental study. Spanish and Portuguese researchers found that rats fed dietary supplements of choline better recognized objects after 48 hours than those on a standard choline intake, while those with a choline deficiency failed to recognize presented items.

 If you’ve got a thing for Froot Loops, a milk chaser could protect your champers. Scientists at Chicago College of Dentistry found that washing down sugary brekkie Cereal with milk reduces acids produced by bacteria in dental plaque on tooth surfaces, potentially warding off cavities. Subjects who consumed 20 grams of dry Froot Loops followed by whole milk had lower plaque acidity than those who chased with apple juice or water.

WOULD YOU RATHER...?
A cheeky pash or dodging lung cancer ?
We reckon your kissing quotient’s an alright trade-off for the reduction in lung cancer risk recently traced to eating raw garlic. Chowing down on the bulb twice a week correlated with decreased lung cancer odds – even in smokers – in a study at China’s Jiangsu Provincial Center for Disease Control and Prevention. Dially sulfide and other elements released when a garlic bulb separates into cloves could take the credit, academics said.
