Best food: Flaxseeds

Flaxseeds are rich in alpha linoleic acid (ALA), lignans and fiber, which work together to relax arteries so blood flows more easily—enough to lower blood pressure by 15 points, according to a report published in the journal Hypertension. The ALA in flax also helps the brain form and cement neural pathways to improve memory. “ALA boosts the production of brain-derived neurotrophic factor,” explains Alicia Galvin, R.D., resident dietitian for Sovereign Laboratories. “This helps protect brain cells from degenerating.” To get the benefits, she recommends incorporating 1 Tbs. of ground flaxseed into your diet daily, suggesting, “Add it to cooked oatmeal, cereal or smoothies or bake it into muffins and bread.”
