PROTEIN RECOMMENDATIONS MIGHT BE TOO LOW

The estimated average requirement for protein is an amount experts believe will meet the needs of half the population. That number is increased by around 20% to determine the Recommended Dietary Allowance (RDA) which is currently 0.8 grams of protein per kilogram of body weight per day. A study published in The Journal of Nutrition suggests that value might be too low.

Researchers analyzed the protein intakes of 6 older men on 7 separate occasions using diets where daily protein intake ranged from 0.2 to 2 grams per kilogram of body weight. After analysis, they determined that a good RDA for those and younger subjects would be in the range of 0.94 and 1.24 grams per kilogram of body weight per day. That’s about 30% more than current estimates.

CARDIO DAY CAN HELP BEAT CHRONIC STRESS

Many people have to deal with the daily stresses of jobs, school studies and other situations. Constant stress can impact blood vessel health by decreasing your body’s capacity for nitric oxide induced vaso-relaxation. New research presented at the Experimental Biology 2016 meeting in San Diego suggests regular cardio exercise can help reduce some negative aspects of everyday stress.

Scientists subjected lab rats to unpredictable episodes of mild stress. Some exercised on a treadmill for 8 weeks while others were inactive. The stressed fit rats showed the greatest maximal blood vessel dilation (90%) compared to the inactive stressed rats (78%). For comparison, a control group of non-stressed rats achieved a rate of 83% dilation.
