Added Sugar in Your Diet can Cause Heart Trouble

-

The following is taken from an article just published online last month that high-lites the dangers of added sugar. Processed foods and bottled drinks (except water) all have added sugar or some type of sugar substitute. For decades we have been feeding our children pre-made frozen foods and other processed foods and drinks, and those habits have been passed down from one generation to the next and finally causing this epidemic of overweight people that we see today. Read the article below and think about how you can make changes in your diet.

Doctors have long thought extra sugar in a person's diet is harmful to heart health because it promotes chronic conditions such as obesity and diabetes.

But the added sugar Americans consume as part of their daily diet can -- on its own, regardless of other health problems -- more than double the risk of death from heart disease, a new study from the U.S. Centers for Disease Control and Prevention has found.

The average American diet contains enough added sugar to increase the risk of heart-related death by nearly 20 percent, the researchers said.

And the risk of death from heart disease is more than doubled for the 10 percent of Americans who receive a quarter of their daily calories from sugar that's been added to food, said CDC researcher and study lead author Quanhe Yang.

The findings were published online Feb. 3 in the journal JAMA Internal Medicine.

"They're seeing that people who are moderately heavy consumers of added sugar have a heightened risk of dying of [heart] disease, and the heaviest users have the highest risk of dying of [heart] disease," said Laura Schmidt, who wrote an accompanying journal commentary. "When you start seeing a dose-response reaction like they found, that is powerful evidence that consuming added sugar puts people at risk of death from cardiovascular disease."

Food manufacturers add sugar to many different products to improve flavor, appearance or texture. People who eat those varied products might not be aware that they have increased their total sugar intake, because the sugar is hidden inside the food, the researchers said.

About 37 percent of the added sugar in Americans' diets comes from sugar-sweetened beverages, the authors said. One 12-ounce can of regular soda contains 9 teaspoons of sugar (about 140 calories), Yang said -- enough to put the person into a higher-risk category if they drink soda daily.

"I could be eating a 2,000-calorie diet, not overeating, not overweight. But if I just drink a can of soda a day, I increase my risk of dying from [heart] disease by one-third," said Schmidt, a professor of health policy at the University of California, San Francisco, School of Medicine. "I think people would assume one can of soda a day would not have that kind of impact over the course of their lives."

Other major sources of added sugar include cakes, pies, fruit drinks, candy, and ice cream and other dairy desserts, the researchers said.

Added sugar can even be found in foods most people would consider savory, such as salad dressing, bread and ketchup, Schmidt said. Another major offender is yogurt, which often comes with as much sugar as you'd find in candy.

Previous research has focused exclusively on the health effects of sugary beverages, Yang said. For the new study, the research team decided to look at how the total amount of added sugar in the American diet can affect the risk of heart-related death.

Recommendations for added sugar consumption vary, and there is no universally accepted threshold for unhealthy levels.

The Institute of Medicine recommends that added sugar make up less than 25 percent of total calories, the World Health Organization recommends less than 10 percent and the American Heart Association recommends limiting added sugars to less than 100 calories daily for women and 150 calories daily for men, according to background information included in the study.

The researchers used national health survey data to review consumption of added sugar. They found that added sugar made up an average of 14.9 percent of daily calories in the American diet from 2005 to 2010, down from 15.7 percent from 1988 to 1994 and 16.8 percent from 1999 to 2004.

Nearly three of four adults consumed 10 percent or more of their daily calories from added sugar, while about 10 percent of adults consumed a quarter or more of their calories from added sugar in the latest study years.

The researchers then compared data on sugar consumption with data on death from heart disease.

The risk of heart-related death increases 18 percent with the average American diet that receives about 15 percent of daily calories from added sugar, compared to diets containing little to no added sugar, the study authors found.

The risk is 38 percent higher for people who receive 17 percent to 21 percent of their calories from added sugar, and more than double for people who get more than 21 percent of their daily diet from added sugar, Yang said.

Although the study found that eating more food with added sugar was tied to a higher risk of heart-related death, it did not prove a cause-and-effect relationship.

The Corn Refiners Association, which represents the manufacturers of one popular form of added sugar, fructose, said it had no comment on the study.

Commentary author Schmidt said added sugar could be increasing heart attack risk by disrupting a person's hormone system, throwing their metabolism out of whack.

By comparison, foods that are naturally rich in sugar -- such as fruit -- also contain lots of fiber and other nutrients, which reduces the impact the sugar has on the body, said Rachel Johnson, a professor of nutrition at the University of Vermont and chairwoman of the American Heart Association's Nutrition Committee.

To avoid added sugar, read Nutrition Facts and ingredients labels carefully, Johnson said. Look out for ingredients that end in -ose, such as fructose or sucrose, as well as any type of syrup, she said.

What's the Mediterranean Diet?

The Mediterranean diet is based on the traditional foods eaten by people living in the Mediterranean region, especially Greece. It's loaded with healthy foods and research findings suggest following this diet may help reduce some of the risk factors for heart disease.  According to the Oldways Preservation & Exchange Trust, the Mediterranean diet was introduced in 1993 by Oldways, Harvard School of Public Health and the World Health Organization.  The diet includes: Olives and olive oil Whole grains, mostly in bread and cereal rather than pasta Very little red meat Fish and seafood Some cheese, but less milk Lots of vegetables and fruit Plenty of legumes and nuts A little red wine The Mediterranean diet is high in fiber and antioxidants from vegetables, legumes and nuts, far greater than the typical Western diet, and low in saturated fat. Very little red meat is eaten in this region, and milk consumption is limited as well, exc...

Changing Your Life To Lose Weight

I can let you in on the ultimate secret for successfully making a change in your life. A century’s worth of psychological research reveals an interesting paradox in who we are. On the one hand, once we reach adulthood our basic personalities remain unchanged for the rest of our lives. We keep doing the same things—and feeling the same ways—over and over. But, on the other hand, every day we change our behavior drastically in response to different environments. Most of us are one person at work, for example, and another person at home. It is easier to change our environment than to change ourselves. So, if you want to change yourself, change your environment. Said differently: Whenever possible, don’t try to fight temptations – avoid them! The easiest way to make a change in your life is to modify the world around you in ways that will naturally drive you toward making, and maintaining, the change you want. There are many ways to change your environment, but let’s focus...

Cancer and High Protein Diets

-
On the Fox TV Network the other night, one of the big stories was about high protein diets. A new study has shown a link between the over consumption of animal protein and how it can stimulate the growth of cancer cells. It seems we all have cancer cells but they don’t normally grow, unless we consume too much animal fat, dairy or fats from processed foods. Before I continue I want to explain about the link to cancer. After all, Man has been eating red meat for millions of years, right. That's true but todays red meat is not the same. Most red meat that we buy in the supermarket comes from Steers that have been raised in feed lots on a grain diet that is full of hormones and other chemicals that shorten the growing time and put more fat on the animal. These hormones and other chemicals stay in the meat and what you're buying will contain the chemicals that the animal ate. Normally a grass feed Steer that lives on the range in big herds will take 18 to 20 months to grow to ...
