“Which Diet Works?”

Category : Health

What follows are excerpts from an interesting article entitled: “Which Diet Works?” dated June 26, 2012 from The New York Times Opinionator Blogs.

So you think “A calorie is a calorie.”  Think again.  Increasing evidence shows that the body treats calories from highly processed carbohydrates differently, spiking blood sugar and insulin and causing us to retain fat.  In a nutshell, all calories are not alike.

A new study looked at people’s ability to maintain weight loss.  Researchers put three groups of people on three different diets:

(1) A standard low-fat diet (60% carbohydrates — with an emphasis on fruits, vegetables and whole grains but not unprocessed ones, 20% fat and 20% protein);

(2) A ultra-low carbohydrate diet such as the Atkins diet (with 10% carbohydrates, 60% fat and 30% protein); and

(3) A low glycemic index diet (with 40% carbohydrate — minimally processed grains, fruit, vegetables and legumes, 40% fat and 20% protein).

The conclusion: The low carbohydrate diet offers the biggest metabolic benefit initially but it has some marked problems. Over the long term, the low glycemic diet appears to work the best.

The advice:  Reacquaint ourselves with the minimally processed carbs.  They give us a better chance of idealizing our weight.

Kellogg’s Frosted Flakes has a serving size of 3/4 cup. Healthy Choice Chicken Tortilla Soup (microwaveable bowl) has a serving size of one cup, and Ritz Crackers have a serving size of five crackers.

According to its label, a pint of Häagen-Dazs ice cream contains four servings. But when was the last time you measured out a fourth of a container of Cookies & Cream, then put the rest away for another day?

For many people, the reality is that much of a pint can easily vanish in one sitting. A large package of Cool Ranch Doritos lists a single serving as one ounce, or roughly 12 chips, but it’s hard to imagine keeping count of every last chip as you dig into a bag. And while 160 calories and two grams of saturated fat may sound like a small price to pay for a serving of Oreo cookies, keep in mind that technically speaking, a serving is a paltry three cookies.

In the face of mounting criticism, the Food and Drug Administration has been under pressure for years to force food makers to include more realistic serving-size information on their labels. The agency regulates the serving sizes that can be listed on packages by providing food makers with detailed guidelines to follow, which list the amounts of a specific food that a person would “customarily consume” in a typical sitting. But critics say these so-called reference amounts are often laughably small because they’re based in part on surveys of eating behavior that were carried out in the 1970s, when Americans ate less food and portions had not been supersized.

Now, in an effort to highlight the problems with some labels, the Center for Science in the Public Interest, a consumer advocacy group, has singled out what it says are some of the worst offenders.

At the top of its list are labels for canned soups, ice cream, coffee creamers and nonstick cooking sprays — all of which grossly understate the calories, sodium and saturated fat the average person typically consumes when eating these foods.

Canned soup may be one of the more stark examples. According to its label, a single serving of Campbell’s Chunky Classic Chicken Noodle soup is one cup — just under half a can — and contains about 790 milligrams of sodium. But in a national survey of 1,000 consumers, only 10 percent of people said they would eat a one-cup portion. Most, about 64 percent, said they would eat an entire can at one time, taking in 1,840 milligrams of sodium in a sitting. That is roughly 80 percent of the 2,300 milligrams recommended as the upper limit for daily salt intake under the 2005 Dietary Guidelines, and well above the 1,500 milligrams that health officials have said about half the population should adhere to (those with hypertension, African-Americans and people over 50).

A similar number of the people asked, 61 percent, said they would also eat the entire can of a condensed soup, like Campbell’s Chicken Noodle, which lists 2.5 servings per can. A single serving contains 890 milligrams of sodium, and the full can has 2,390 milligrams. About 27 percent of respondents said they would eat just half a can in one sitting.

The group also took issue with the “Healthy Request” labels, which are for soups that fall below 480 milligrams of sodium per serving. Campbell’s has worked hard to lower sodium below that level, bringing its “Healthy Request” versions of Chunky Chicken Noodle and condensed Chicken Noodle down to 410 milligrams of sodium per serving. But the amount of sodium that people actually end up consuming when they eat an entire can, “is enormous,” said Michael Jacobson, the group’s executive director.

The findings were based on a questionnaire commissioned by the Center for Science in the Public Interest and carried out by Opinion Research Corporation in Princeton, N.J.

Another product that made the list of egregious offenders was cooking sprays, which list nutritional information based on “ridiculously tiny serving sizes,” the group said. One of the most popular, PAM, boasts zero calories and zero fat on the label of its original canola cooking spray. But that information refers to a spray lasting just a quarter of a second.

“That’s just not the way people use them,” Mr. Jacobson said. “It’s probably impossible to spray for a third of a second. We suggested six seconds might be kind of reasonable.” A six-second spray, he said, has 50 calories and six grams of fat.

Coffee creamers are another overlooked source of fat and calories. Coffee-mate, a popular flavoring, lists nutritional information based on a single teaspoon, even though many people are likely to dump far more than that into their morning cuppa. A look at the label of Fat Free Original Coffee-mate leads people to think they’re getting 10 calories and zero fat, when a two-tablespoon serving — a more realistic serving size, the group says — would add 50 calories and 1.6 grams of saturated fat. That’s almost identical to two tablespoons of ordinary half and half: about 40 calories and two grams of saturated fat.

“Over the years we’ve looked and laughed at many serving sizes,” Mr. Jacobson said, “and these are some of the foods where the label serving is just so different from what people actually consume.”

The F.D.A. has been in the process of revising existing food labels since 2005. But the agency has been somewhat tight-lipped about where it is in the process and any changes it plans to make, like whether labels should include details on added sugars or just total sugar, for example, and whether calories should be emphasized less or more than they are now, Mr. Jacobson said.

This fall, the Institute of Medicine is expected to release its own report on food packaging and labeling as well.

Pick Low-Fat Dairy Products to Lower Your Stoke Risk

0

Category : Health

Dairy products such as milk, cheese, and yogurt, are a great source of nutrients. However, the variety of non-fat, low fat, and regular products available can leave a health seeking consumer confused.  A recent study has found that adults that consumed a higher amount of low-fat diary products had a slightly lower risk of stroke compared to those that consumed high fat dairy products. High fat dairy has more saturated fat compared to lower fat products, which can affect cholesterol levels. So next time you pick up a dairy product, try a lower fat option!

A Mediterranean diet may promote brain health

We may want to take a second look at the Mediterranean diet.  It has been associated with a considerable number of health benefits.  A newly released study finds this diet linked to a lower incidence of small vessel damage in the brain.

The Mediterranean diet has been linked to a host of health benefits, including a lower risk of heart disease, cancer and diabetes. A study finds that the diet may also be associated with a decreased chance of small vessel damage in the brain.

The diet, popular in Mediterranean countries, includes little red meat but lots of fresh vegetables and fruit, lean proteins, whole grains and healthy monosaturated fats from olive oil and nuts.

In the study, released Monday in the Archives of Neurology, researchers analyzed diet information on 966 people, average age 72, who answered a food questionnaire to see how close they came to consuming a Mediterranean diet. The participants also underwent magnetic resonance imaging to measure white matter hyperintensity volume. White matter hyperintensity, according to the authors, is an indicator of small vessel damage. That damage can be part of the normal aging process but is also linked with risk factors such as high blood pressure, diabetes and smoking.

The consequences can be serious, increasing the chances of stroke and dementia in more serious cases.

Overall, researchers found that adhering more closely to a Mediterranean diet was associated with a lower incidence of white matter hyperintensity volume, and that remained after controlling for risk factors such as smoking, physical activity, high blood pressure and diabetes.

Among other findings: More men than women stuck to a Mediterranean diet, and those who were more physically active were also more apt to eat more foods associated with the diet.

While the results suggested that the ratio of monosaturated fat to saturated fat may be a key component in determining levels of white matter hyperintensity volume. However, the authors added that the overall diet, rather than specific pieces of it, may be more important.

Low blood levels of omega-3 fatty acids are associated with smaller brain volume and poorer performance on tests of mental acuity, even in people without apparent dementia, according to a new study.

In the analysis, published online Monday in the journal Neurology, scientists examined 1,575 dementia-free men and women whose average age was 67. The researchers analyzed the fatty acids of the subjects’ red blood cells, a more reliable measurement than a plasma blood test or an estimate based on diet. They used an M.R.I. scan to measure brain volume and white matter hyperintensities, a radiological finding indicative of vascular damage.

People in the lowest one-quarter for omega-3 levels had significantly lower total cerebral brain volume than those in the highest one-quarter, even after adjusting for age, body mass index, smoking and other factors. They also performed significantly worse on tests of visual memory, executive function and abstract memory than those in the highest one-quarter. There was no significant association with white matter hyperintensity volume.

“We feel that omega-3’s reduce vascular pathology and thus reduce the rate of brain aging,” said Dr. Zaldy S. Tan, the lead author and associate professor of medicine at the University of California, Los Angeles.

Few in the study were taking omega-3 supplements, Dr. Tan said. The main reason that some had higher blood levels of omega-3’s was that they ate more fatty fish.

Several of the authors have financial relationships with pharmaceutical companies…
