Highfalutin lutein: Get the most out of this phytonutrient
When Sade (pronounced “sha-day”) sings “Smooth Operator” your heartbeat slows, your shoulders relax, you feel calmer. That’s good for heart ‘n’ soul! Well, smoothies can do the same for you if you make them with spinach or other dark green, leafy veggies.
Researchers from Sweden’s Linkoping University have studied the nutrient lutein — a fat-soluble pigment that’s abundant in dark-green vegetables — and found that it tamps down inflammation in immune system cells and your body stores it to use if needed to help cool heart-damaging inflammation.
That made them wonder: What’s the best way to prepare lutein-rich foods to make sure you get the most of that nutrient in every tasty mouthful? So, for a new study, published in Food Chemistry, they fried, boiled and steamed baby spinach, and then measured the surviving lutein content. They compared that to raw spinach and found that the highest lutein levels were maintained when uncooked spinach was chopped into tiny pieces — like when it’s added to a smoothie. So, try our favorites!

What happens when teens get enough sleep?
Sarah Michelle Gellar played Buffy Summers in TV’s “Buffy the Vampire Slayer,” which, among other things, was about getting through high school on very little sleep. Buffy spent most nights fighting mythical creatures. As a result, she could barely keep her eyes open in class, and her academics suffered.
While most high-schoolers aren’t out all night battling vampires, research finds that most are sleep-deprived. One study found that 40 percent of teens in the U.S. sleep less than seven hours nightly.
Many experts say this could be fixed by starting school later in the day. Recently, a pilot program called Sleepmore in Seattle was introduced at two high schools in Seattle. The program delayed the morning start time from 7:50 to 8:45a.m. so teens could get a half-hour more sleep and experience less drowsiness during the day.
It paid off. Many teens improved their academic performance. The late start time was associated with a 4.5 percent increase in median grades. And teens from economically disadvantaged homes had better attendance and were late less often.
So, while you’re lobbying for a change of your teen’s school start time, you can also make sleep hygiene a priority at your house. Experts say that teens need at least nine hours of sleep each night. Encourage your teen to develop a nighttime routine that achieves close to that. Regular physical activity and stress management help regulate the sleep/wake cycle. Also, the bed should be used only for sleep — no texting or tweeting!
