Does Sugar Affect Cholesterol Levels?

Seattle NutritionistAngela Pifer writes:  

 

If you have high cholesterol, chances are you were instructed to reduce your intake of total fat, specifically animal fats, from your diet, become more active and to work on weight loss. What you weren’t told is that you should also address your sugar intake. A new study published in the Journal of American Medical Association looked at the blood profiles and sugar intake of more than 6,100 adults (whose demographics were representative of the American population). On average, study participants consumed 21.4 teaspoons of sugar a day (24 teaspoons equals ½ cup!). Those who took in more sugar had lower levels of HDL (‘good’) cholesterol and higher levels of triglycerides. It seems that the message is clear, added dietary sugar is connected with poor lipid profiles.

  

 

This is the first study to look at the connection between how much added sugars and ‘empty’ calories people consume and the effect on blood lipid profiles. Some factors for heart disease, like family history, cannot be changed. By identifying added dietary sugars as a contributor for a poor lipid profile people at risk can now begin to address what can be changed.  

  

In addition, the study found that:

  

 

· On average, people consumed 10.6% more calories from sugar a day than they did in the 1970’s.  

· The higher the intake of added sugar, the lower the person's HDL ("good") cholesterol. Participants consuming 10% of total calories from added sugar had three times the risk of having low HDL than someone who took in half that much sugar.

· Participants with a higher intake of added sugar tended to have higher triglyceride levels as well.

· **Women who took in more added sugar also had higher LDL ("bad") cholesterol.

 

 

How much Added Sugar is Too Much Sugar?  

 

To make matters more confusing, medical and health organizations do not agree on a current recommendation. Depending on whom you ask the daily consumption of added sugars should fall below:  

 

· 25% , according to the Institute of Medicine

· 10%, according to the World Health Organization

· 6% or 7%, according to the American Heart Association

 

  

The Type of Sugar Matters 

 

Though it would seem that Americans are eating a lot more sugar now than they did forty years ago, they are not. Sugar calories are up just 10% over those consumed in the 1970’s. What is different is the type of sugar people are consuming. In the 1970’s people consumed on average 343 calories a day of refined cane and beet sugar and only 2 calories from high-fructose corn syrup (HFCS). High-fructose corn syrup has now risen to 41% of Americans total sugar intake. It is also the single most consumed caloric nutrient for the American Population.  

 

  

The Cost of Calories 

 

One of the reasons Americans are eating more calories from high-fructose corn syrup today than in the 1970’s is due to government incentives on corn production and tariffs on sugar. It is simply less expensive to produce HFCS than it is to produce cane or beet sugar.

  

 

A person might expect that added sugars, along with other food groups, have increased equally over time in response to inflation. That person would be wrong. The inflation-adjusted cost of added sugars has dropped by half since 1970. This change can be credited to the steep rise of low-cost ‘foods’ containing high-fructose corn syrup over the last thirty years.

  

 

Over the past forty years, the price of added sugars has dropped significantly more than the purchase price of each food group:

  

 

· Fruit sources: 30% increase

· Vegetable sources: Unchanged

· Grain sources: 29% decrease

· Dairy sources: 38% decrease

· Fat sources: 38% decrease

· Protein sources: 50% decrease

· Sugar sources: 50% decrease

 

  

What Can You do?  

 

· Read nutrition labels and take note of how much added sugar you consume.

· Reduce or replace foods containing corn syrup, high-fructose corn syrup, cane or beet sugar or sucrose.

· Replace soda with water, sparkling water or mineral water.

· Choose whole foods whenever possible. Fruit is a perfectly healthy addition to your eating plan. Eat frequently across the day and incorporate into green salads and grain dishes.

· Be patient. As you move away from sugar added foods it will take some time for your taste receptors to lower for perceived sweetness. Whole foods may taste a little bland at first, but as your taste receptors begin to adjust you will be able to taste the sweetness in real whole foods.

Be stingy when adding sugars or other sweeteners, like honey and maple syrup. This includes watching how much you’re putting into coffee or on oatmeal (Bauer recommends no more than one to two teaspoons).

I strictly recommend not to hold off until you get big sum of money to buy all you need! You can take the personal loans or just college loan and feel yourself free

WE never see ourselves as others see us. With all due respect, Ed described you perfectly: "I am always amazed at your need to do things that are totally foreign to you, while all the while needing to never fail. It is a confusing combination - but it always works!"

Yassy, I totally understand your worries. I bet most people can. But I have to say you are the best orderer I know! I always know I'm in for a good meal when I let you do the choosing. Really truly. xo

A constant conversation I have with some, by no means all, of my European colleagues is to argue to them: don’t apply rules to the Government of Israel that you would never dream of applying to your own country. In any of our nations, if there were people firing rockets, committing acts of terrorism and living next door to us, our public opinion would go crazy. And any political leader who took the line that we shouldn’t get too excited about it, wouldn’t last long as a political leader. This is a democracy.

That was very clever to grab the opportunity. It is about right message at the right time. Also to be consider when doing these kind of campaign is to make sure it is relevant to your corporate or product and is sending the right positive message. In case of waynn it clearly sent the message they don't support drug. And what can be better pr than Paris Hilton. Like David mentioned 2.6 million visitors

Yeah~~~~~~~~~~`This has nothing to do with layers. You can either individually select or window select objects to be isolated or hidden. Good!!!!!!!!!!!!

Well, Jimbino, I'm sure you must be right about much of this, including my myopia. For while I've little doubt that as a country we're very many of these -ists that you enumerate, I've quite lost sight of what any of it has to do with the merits of what I'm actually proposing.

I think that you might have lost sight of something too, however. For if you look back to what I wrote, you'll note that I did not endorse the ownership/stakeholding link (though I do think it bears sufficient prima facie plausbility to warrant empirical investigation of the sort that folk at the Wash U. Social Welfare dept like Michael Sherraden do a lot of), but simply cited it as an oft-heard rationale that can rationalize more than some right-wing users of it seem to appreciate.

I highly think that sugar does contribute to the cholesterol, we should control it.
