Two-thirds of our calories now come from just four crops: rice, soy, wheat and corn

Nicholas Kristof - Food for the Soul - NYTimes.com:

"Michael Pollan, the food writer, notes that monocultures in the field result in monocultures in our diets. Two-thirds of our calories, he says, now come from just four crops: rice, soy, wheat and corn. Fast-food culture and obesity are linked, he argues, to the transformation from family farms to industrial farming."

List of the most nutritious nuts

David H. Murdock: The "Nut" In Nutritious:

"In my first blog post, I wrote about the benefits of thirty-three of the healthiest fruit and vegetables on earth, describing the nutrition benefits of each. The post garnered over 100,000 readers, and generated nearly 400 reader comments, many of which asked for more information. People asked: "What about nuts? What about beans? What about fish? Aren't they healthy, too?" My answer is: "Yes, of course!"

Therefore, my next ten posts will be devoted to covering ALL the areas crucial to longevity.... Though I'm not a scientist, everything my Dole Nutrition Institute publishes is based on scientific research. So this second post will provide information readers requested on nuts - and why you should include them in your diet.

ALMONDS: My favorite - especially when covered in dark chocolate! Top nut source of vitamin E, to protect the heart, slow aging, and bolster immunity.

WALNUTS: Top nut in heart-healthy, brain-boosting omega-3 oils. The omega-3 oils in walnuts could help calm and moisten dry, irritated skin. Walnuts also contain a unique form of vitamin E thought to suppress prostate and lung cancer cell division.

PECANS: Top nut in antioxidants. This means they can help neutralize the free radicals that can accelerate aging and cause DNA damage. Pecans may also lower cholesterol.

PEANUTS: Though not strictly a nut (they are in fact a legume), peanuts contain more protein than tree nuts. They also contain the potent antioxidant resveratrol -- famously found in red wine.

PISTACHIOS: Top nut in potassium, needed to maintain healthy blood pressure. Also top nut in phytosterols (plant compounds that inhibit cholesterol absorption).

CASHEWS: Top nut in zinc, a mineral needed to support vision and immunity.

PINE NUTS: Top nut in manganese, essential for bone health and wound healing.

BRAZIL NUTS: Top nut in selenium, a mineral needed for proper thyroid and immune health. Selenium may also protect against cancers of the prostate, liver and lungs. Don't eat more than four a day.

MACADAMIA NUTS: Often shunned because they have more saturated fat than other nuts. However, researchers have found that a handful of macadamia nuts a day reduced total cholesterol by about 9%.

These are the kinds of things we are studying at our North Carolina Research Campus. It is the only campus in the world encompassing eight universities all working together for the benefit of health and longevity. These include Duke University, UNC Chapel Hill, NC State University, UNC Charlotte, North Carolina Central University, NC A&T State University, UNC Greensboro and Appalachian State University. Our Dole Nutrition Institute publishes articles, brochures, videos and our Dole Nutrition News, which you can receive by signing up at www.dolenutrition.com.

Every seven years you shed about half your friendships and acquire new ones

The other seven-year itch - THE WEEK:

"The other seven-year itch

Every seven years, a new study finds, you shed about half your friendships and acquire new ones. Though your best friend may seem like your permanent confidant, there’s only a 30 percent chance that you will be that close to the same person seven years from now. As for the rest of your friends, only 48 percent will still be a regular part of your life in 2016. It’s not that most of us are fickle or disloyal, says Dutch sociologist Gerald Mollenhorst, who conducted the study of more than 1,000 people over seven years. It’s simply that people come together in “friendship networks” mostly out of circumstance and context; when they move away, switch jobs, and experience other major life changes, bonds become attenuated and often dissolve. At the same time, new contexts and new people lead to new friendships. We’d all like to believe we’ve chosen friends and mates because of some inherent affinity, Mollenhorst tells ScienceDaily.com, but the reality is that happenstance and sheer proximity play a big role."

Why people blush

"Why people blush

When some fair-skinned people feel embarrassment, they blush. When they blush, they get more embarrassed, because they feel that it’s a sign of weakness—visible proof that they can’t keep their cool. Stop worrying, says new research: Blushing is actually good for your social reputation. When researchers asked a group of volunteers to judge people’s personalities based on photos, people who were pictured with a pink flush were more likely to be seen as sympathetic characters. In another study, scientists found that blushing can hasten bonding in a fraternity-like setting. “It was a subtle effect, but we found that the frequency of blushing predicted how well these guys were getting along at the end,” psychologist Dacher Keltner tells The New York Times. Blushing signals to others that you have a heart and are sensitive to what other people think of you. It’s therefore endearing. “A blush comes online in two or three seconds,” Keltner says, “and says, ‘I care.’”"

Why tots shouldn’t watch TV

"Why tots shouldn’t watch TV

If you have a baby or a toddler, turn off that TV. A new study finds that when children are exposed to a lot of TV before the age of 2, they are deprived of interaction with adults, which can lead to delays in brain and language development. University of Washington researchers found that for every hour the TV set was on, even if it was just in the background, adults spoke from 500 to 1,000 fewer words to children. When the distraction of the boob tube was present, children spoke less, too, and there were fewer conversations between the adults and the children. This was true whether the show was a kid’s program or an adult show that parents were watching in the child’s presence. Speaking directly to a child, previous research has shown, is critical to brain development. In surveys, 30 percent of Americans admit to having the TV on all day long, whether anyone is watching or not. Television, researcher Dimitri Christakis tells LiveScience.com, “is a poor caregiver substitute. My recommendation is that children under the age of 2 be discouraged from watching television.”"

A Recipe For Longevity: 33 Of The Healthiest Foods On Earth"

"Is it possible to live to 125 or maybe 150? It's certainly a possibility, as discussed on Oprah Winfrey's recent show on longevity. She visited me at my farm to learn how, at 86, I am enjoying the robust health, energy, and mental creativity of someone many decades younger. My secret: large quantities of fruit and vegetables, plus an hour of daily exercise.

No pills, not even aspirin, and certainly no supplements ever enter my mouth -- everything I need comes from my fish-vegetarian diet, which incorporates 30-40 different kinds of fruit and vegetables every week. Even though I am Chairman and Owner of Dole Food Company, I do most of my own grocery shopping, and even took Oprah on an impromptu trip to Costco, in a day that included bike riding, exercise in the gym, and juicing vegetables in the kitchen. Oprah marveled at how much I eat, and yet never gain a pound. In fact, I expend a lot of energy in my 50-60 minutes of cardio and strength training every day. Plus there's the fact that fruit and vegetables tend to be lower in calories, but higher in filling fiber and other nutrients that help you feel satisfied.

By eating many fruits and vegetables in place of fast food and junk food, people could avoid obesity. Obesity accelerates aging even faster than smoking, according to scientific research.

We created the North Carolina Research Campus to study the health benefits of fruits and vegetables. It is the only campus in the world encompassing eight universities all working together for the benefit of health and longevity. These include Duke University, UNC Chapel Hill, NC State University, UNC Charlotte, North Carolina Central University, NC A&T State University, UNC Greensboro and Appalachian State University. We've gathered a comprehensive array of famous scientists and scientific equipment under one roof, including a two-story, 950 megahertz, 8-ton superconducting magnet. It is the largest and most powerful magnet in the world and will help us look at both plant and human cells at the most minute level. We are constantly doing research on all fruit and vegetables, including the ones listed below, which are the mainstay of my diet.
