Less salt may keep your arteries more flexible
Arteries tend to stiffen after age 30 and can increase risk of heart attack, stroke and memory loss because they can’t dilate (widen) when increased blood volume is necessary. Australian researchers studied 25 overweight or obese subjects with normal blood pressure and found those on a diet with lower sodium levels (2600 mg/day) had arteries that could dilate more than those on a diet with normal sodium levels (3600 mg/day).
PositiveTip: Choose to pass over the salt at mealtime and select low-sodium foods.
Fitness during transition from the teenage years to adulthood protects against heart disease.
A study of 743,498 Swedish men examined during conscription at about 18 years old has revealed those with lower aerobic fitness levels were significantly more likely to have a heart attack 30+ years later. The obese participants consistently experienced higher rates compared to their leaner peers regardless of fitness level.
PositiveTip: Family activities which lead to consistently greater fitness for teens support better health years in the future.
