What 2000 Calories Looks Like

Here, we show you what roughly 2,000 calories looks like at some large chains. (Depending on age and gender, most adults should eat between 1,600 and 2,400 calories a day.) Researchers have long understood that people are more likely to finish what’s on their plate than to stop eating because they’ve consumed a given amount of food. It’s “the completion compulsion,” a phrase coined in the 1950s by the psychologist Paul S. Siegel. Combine that compulsion with the rising number of restaurant meals Americans eat and the substance of those meals, and you start to understand why we’ve put on so much weight. But there is some good news: As you’ll see below, it’s not so hard to eat bountifully and stay under 2,000 calories. It’s just hard to do so at most restaurants.

Study Questions Fat and Heart Disease Link

Many of us have long been told that saturated fat, the type found in meat, butter and cheese, causes heart disease. But a large and exhaustive new analysis by a team of international scientists found no evidence that eating saturated fat increased heart attacks and other cardiac events.
The new findings are part of a growing body of research that has challenged the accepted wisdom that saturated fat is inherently bad for you and will continue the debate about what foods are best to eat.

Eat Plants And Prosper: For Longevity, Go Easy On The Meat, Study Says

A new study linking animal protein-rich diets to increased mortality in middle age adds fuel to the controversy over how much protein — and from what sources — is ideal for health. One thing that seems pretty clear: It doesn't hurt to go heavy on the greens.

The Full-Fat Paradox: Whole Milk May Keep Us Lean

I have to admit, I melt at the creaminess of full-fat yogurt.
It's an indulgence that we're told to resist. And I try to abide. (Stealing a bite of my daughter's YoBaby doesn't count, does it?)
The reason we're told to limit dairy fat seems pretty straightforward. The extra calories packed into the fat are bad for our waistlines — that's the assumption.
But what if dairy fat isn't the dietary demon we've been led to believe it is? New research suggests we may want to look anew.
Consider the findings of two recent studies that conclude the consumption of whole-fat dairy is linked to reduced body fat.
In one paper, published by Swedish researchers in the Scandinavian Journal of Primary Health Care, middle-aged men who consumed high-fat milk, butter and cream were significantly less likely to become obese over a period of 12 years compared with men who never or rarely ate high-fat dairy.
Yep, that's right. The butter and whole-milk eaters did better at keeping the pounds off.
"I would say it's counterintuitive," says Greg Miller, executive vice president of the National Dairy Council.

More Signs A Mediterranean Diet Helps Prevent Cardiovascular Ills

There's fresh evidence that a Mediterranean diet can help cut the risk ofatherosclerosis, a disease caused by the buildup of plaque in the arteries. 

A new analysis, published in the Journal of the American Medical Association,builds on the work of a prior study, which looked at how a diet rich in fruits, vegetables, whole grains, nuts, fish and healthful oils — namely olive oil — cuts the risk of heart attacks and strokes. That earlier study found that the risk was 30 percent lower for people eating the Mediterranean diet compared with those on a standard low-fat diet.

Kale? Juicing? Trouble Ahead

And now, in the Whole Foods era, as I push my shopping cart down spacious aisles stocked with nonprocessed, gluten-free, non-G.M.O., heirloom, grass-fed, free-range and artisanal goods, I am pleased to know that I was ahead of my time.
Imagine my shock, then, at my last physical, when my doctor told me I had hypothyroidism, common in women over 40. When I got home I looked up the condition on the Internet and found a list of foods to avoid. Kale, which I juiced every morning, tops the list, followed by broccoli, cauliflower, cabbage, Brussels sprouts and collard greens — the cruciferous vegetables I consumed in large quantities because they are thought to prevent cancer, which runs in my family. And flax — as in the seeds — high in omega 3’s, that I sprinkled on cereal and blended in strawberry almond milk smoothies. Also forbidden: almonds and strawberries, not to mention soy, peaches, peanuts, corn, radishes, rutabaga and spinach.
And then, as if my world was not sufficiently rocked, I went to the dentist, who said I had five cavities and asked if I snacked on candy and sodas all day long. I was insulted. Indignant. What did he take me for? No, I answered. I don’t eat sugar and drink only fresh vegetable juices — no longer kale, of course, but carrot and celery, which I’m still allowed. And filtered water with lemon.
“You’d be better off with chocolate and cola,” he said. Apparently the natural sugars in fruit and vegetable juices can cause decay, and lemon, though high in vitamin C and bioflavonoids which may prevent cancer, had eroded the enamel that protected my teeth.
I argued that I always brushed afterward. “Worst thing you can do,” he said. “That’s when the teeth are most vulnerable. Always wait half an hour after eating or drinking anything before brushing your teeth. And don’t brush more than twice daily. You’re destroying what little enamel you have left.”

Snacking Your Way to Better Health


The more often nuts were consumed, the less likely participants were to die of cancer, heart disease and respiratory disease, and not because nut eaters succumbed to other diseases. Their death rate from any cause was lower during the years they were followed. (The nuts in question were pistachios, almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, peanuts and walnuts.)
Those who ate nuts seven or more times a week were 20 percent less likely to die from 1980 to 2010; even among those who consumed nuts less often than once a week, the death rate was 11 percent lower than for those who did not eat them.
I know what you’re thinking: Aren’t nuts fattening? Yes, an ounce of nuts has 160 to 200 calories, nearly 80 percent from fat.
But in study after study, the more often people ate nuts, the leaner they tended to be.

Some of My Best Friends Are Germs

A long but good read by the author Michael Pollen...
Uvealblues
I can tell you the exact date that I began to think of myself in the first-person plural — as a superorganism, that is, rather than a plain old individual human being. It happened on March 7. That’s when I opened my e-mail to find a huge, processor-choking file of charts and raw data from a laboratory located at the BioFrontiers Instituteat the University of Colorado, Boulder. As part of a new citizen-science initiative called the American Gut project, the lab sequenced my microbiome — that is, the genes not of “me,” exactly, but of the several hundred microbial species with whom I share this body. These bacteria, which number around 100 trillion, are living (and dying) right now on the surface of my skin, on my tongue and deep in the coils of my intestines, where the largest contingent of them will be found, a pound or two of microbes together forming a vast, largely uncharted interior wilderness that scientists are just beginning to map.
(..)
o the extent that we are bearers of genetic information, more than 99 percent of it is microbial. And it appears increasingly likely that this “second genome,” as it is sometimes called, exerts an influence on our health as great and possibly even greater than the genes we inherit from our parents. But while your inherited genes are more or less fixed, it may be possible to reshape, even cultivate, your second genome.

Eggs, Too, May Provoke Bacteria to Raise Heart Risk


For the second time in a matter of weeks, a group of researchers reported a link between the food people eat and bacteria in the intestines that can increase the risk of heart attacks.
The lecithin study, published Wednesday in The New England Journal of Medicine, is part of a growing appreciation of the role the body’s bacteria play in health and disease. With heart disease, investigators have long focused on the role of diet and heart disease, but expanding the scrutiny to bacteria adds a new dimension.
Heart disease perhaps involves microbes in our gut,” said the study’s lead researcher, Dr. Stanley Hazen, chairman of the department of cellular and molecular medicine at the Cleveland Clinic Lerner Research Institute. 
(..)
To show the effect of eggs on TMAO, Dr. Hazen asked volunteers to eat two hard-boiled eggs. They ended up with more TMAO in their blood. But if they first took an antibiotic to wipe out intestinal bacteria, eggs did not have that effect.
To see the effects of TMAO on cardiovascular risk, the investigators studied 4,000 people who had been seen at the Cleveland Clinic. The more TMAO in their blood, the more likely they were to have a heart attack or stroke in the ensuing three years.

Culprit in Heart Disease Goes Beyond Meat’s Fat


The researchers had come to believe that what damaged hearts was not just the thick edge of fat on steaks, or the delectable marbling of their tender interiors. In fact, these scientists suspected that saturated fat andcholesterol made only a minor contribution to the increased amount of heart disease seen in red-meat eaters. The real culprit, they proposed, was a little-studied chemical that is burped out by bacteria in the intestines after people eat red meat. It is quickly converted by the liver into yet another little-studied chemical called TMAO that gets into the blood and increases the risk of heart disease.
That, at least, was the theory. So the question that morning was: Would a burst of TMAO show up in people’s blood after they ate steak? And would the same thing happen to a vegan who had not eaten meat for at least a year and who consumed the same meal?
The answers were: yes, there was a TMAO burst in the five meat eaters; and no, the vegan did not have it. And TMAO levels turned out to predict heart attack risk in humans, the researchers found

The Extraordinary Science of Addictive Junk Food


..The meeting was remarkable, first, for the insider admissions of guilt. But I was also struck by how prescient the organizers of the sit-down had been. Today, one in three adults is considered clinically obese, along with one in five kids, and 24 million Americans are afflicted by type 2 diabetes, often caused by poor diet, with another 79 million people having pre-diabetes. Even gout, a painful form of arthritis once known as “the rich man’s disease” for its associations with gluttony, now afflicts eight million Americans.
The public and the food companies have known for decades now — or at the very least since this meeting — that sugary, salty, fatty foods are not good for us in the quantities that we consume them. So why are the diabetes and obesity and hypertension numbers still spiraling out of control? It’s not just a matter of poor willpower on the part of the consumer and a give-the-people-what-they-want attitude on the part of the food manufacturers. What I found, over four years of research and reporting, was a conscious effort — taking place in labs and marketing meetings and grocery-store aisles — to get people hooked on foods that are convenient and inexpensive. I talked to more than 300 people in or formerly employed by the processed-food industry, from scientists to marketers to C.E.O.’s. Some were willing whistle-blowers, while others spoke reluctantly when presented with some of the thousands of pages of secret memos that I obtained from inside the food industry’s operations. What follows is a series of small case studies of a handful of characters whose work then, and perspective now, sheds light on how the foods are created and sold to people who, while not powerless, are extremely vulnerable to the intensity of these companies’ industrial formulations and selling campaigns.
(..)
To get a better feel for their work, I called on Steven Witherly, a food scientist who wrote a fascinating guide for industry insiders titled, “Why Humans Like Junk Food.” I brought him two shopping bags filled with a variety of chips to taste. He zeroed right in on the Cheetos. “This,” Witherly said, “is one of the most marvelously constructed foods on the planet, in terms of pure pleasure.” He ticked off a dozen attributes of the Cheetos that make the brain say more. But the one he focused on most was the puff’s uncanny ability to melt in the mouth. “It’s called vanishing caloric density,” Witherly said. “If something melts down quickly, your brain thinks that there’s no calories in it . . . you can just keep eating it forever.”
(..)
But the largest weight-inducing food was the potato chip. The coating of salt, the fat content that rewards the brain with instant feelings of pleasure, the sugar that exists not as an additive but in the starch of the potato itself — all of this combines to make it the perfect addictive food. “The starch is readily absorbed,” Eric Rimm, an associate professor of epidemiology and nutrition at the Harvard School of Public Health and one of the study’s authors, told me. “More quickly even than a similar amount of sugar. The starch, in turn, causes the glucose levels in the blood to spike” — which can result in a craving for more.

The New Science Behind America's Deadliest Diseases

What do heart disease, diabetes, Alzheimer's, stroke and cancer have in common? Scientists have linked each of these to a condition known as chronic inflammation, and they are studying how high-fat foods and excess body weight may increase the risk for fatal disorders.
Link
Inflammation is the body's natural response to injury and outside irritants. But when the irritants don't let up, because of a diet of high-fat foods, too much body fat and smoking, for example, the immune system can spiral out of control and increase the risk for disease. Experts say when inflammation becomes chronic it can damage heart valves and brain cells, trigger strokes, and promote resistance to insulin, which leads to diabetes. It also is associated with the development of cancer.
(..)
"We've learned that abdominal fat tissue is a hotbed of inflammation that pours out all kinds of inflammatory molecules," Dr. Libby says. The most important step patients can take is to lose excess weight, which can reduce inflammation in a matter of weeks or months, he says.
(..)

Greater dietary fiber consumption was associated with lower levels of C-reactive protein and other markers in the blood that signal inflammation, according to a new study involving nearly 600 adolescents published in the Journal of Clinical Endocrinology and Metabolism. Norman Pollock, a researcher at Georgia Health Sciences University and a co-author of the study, says one explanation may be that fiber is associated with higher levels of a protein hormone that improves insulin sensitivity, which in turn lowers levels of inflammation.
A combination of nutrients found in dairy food may also help ease inflammation in patients at risk for heart disease, stroke and diabetes.

Losing 'Virginity': Olive Oil's 'Scandalous' Fraud

Extra-virgin olive oil is a ubiquitous ingredient in Italian recipes, religious rituals and beauty products. But many of the bottles labeled "extra-virgin olive oil" on supermarket shelves have been adulterated and shouldn't be classified as extra-virgin, says New Yorker contributor Tom Mueller.
Mueller's new book, Extra Virginity: The Sublime and Scandalous World of Olive Oil, chronicles how resellers have added lower-priced, lower-grade oils and artificial coloring to extra-virgin olive oil, before passing the new adulterated substance along the supply chain. (One olive oil producer told Mueller that 50 percent of the olive oil sold in the United States is, in some ways, adulterated.)

How to Make Oatmeal . . . Wrong

Raw oats with milk and honey is my favorite way!
Uvealblues

There’s a feeling of inevitability in writing about McDonald’s latest offering, their “bowl full of wholesome” — also known as oatmeal. The leading fast-food multinational, with sales over $16.5 billion a year (just under the GDP of Afghanistan), represents a great deal of what is wrong with American food today. From a marketing perspective, they can do almost nothing wrong; from a nutritional perspective, they can do almost nothing right, as the oatmeal fiasco demonstrates.
(..)
Like so many other venerable foods, oatmeal has been roundly abused by food marketers for more than 40 years. Take, for example, Quaker Strawberries and Cream Instant Oatmeal, which contains no strawberries, no cream, 12 times the sugars of Quaker Old Fashioned Oats and only half of the fiber. At least it’s inexpensive, less than 50 cents a packet on average. (A serving of cooked rolled oats will set you back half that at most, plus the cost of condiments; of course, it’ll be much better in every respect.)
(..)
Others will argue that the McDonald’s version is more “convenient.” This is nonsense; in the time it takes to go into a McDonald’s, stand in line, order, wait, pay and leave, you could make oatmeal for four while taking your vitamins, brushing your teeth and half-unloading the dishwasher. (If you’re too busy to eat it before you leave the house, you could throw it in a container and microwave it at work. If you prefer so-called instant, flavored oatmeal, see this link, which will describe how to make your own).
If you don’t want to bother with the stove at all, you could put some rolled oats (instant not necessary) in a glass or bowl, along with a teeny pinch of salt, sugar or maple syrup or honey, maybe some dried fruit. Add milk and let stand for a minute (or 10). Eat. Eat while you’re walking around getting dressed. And then talk to me about convenience.
