Glycemic load influences cholesterol

[Guest guest]

Friends,

 

This AJCN abstract may be of interest to some. As indicated in a

previous post, the science is nicely discussed in an 8 page review

paper at http://www.cardiab.com/content/1/1/1. That review paper

notes that atherosclerosis is " caused " by hyperglycemia. The AJCN

abstract below notes that hyperglycemia may also correlate to lower

HDL levels. What this means to me as a distance runner is that fruit

and " gels " may be a better support of aerobic activity than refined

starch (flour products, etc.). Note further that in previous

discussions that non-starchy vegetables, fruits and small amounts of

lean protein was my own recommended method of avoiding hyperglycemia

and insulin resistance while supporting an aerobic athletic lifestyle.

MILWAUKEE--High glycemic load is negatively correlated to serum

levels of beneficial high-density lipoprotein (HDL) cholesterol,

according to a study published in the February issue of the American

Journal of Clinical Nutrition (81, 2: 376-379, 2005) (www.ajcn.org).

 

Scientists assessed the relationship between blood levels of lipids

and diet in a test population of 32 healthy males and females aged 11

to 25 years. Subjects' serum lipid values and body mass index scores

were varied. Dietary intake was appraised through three-day food

diaries. A negative correlation between glycemic load (in relation to

factors including refined flours, total dietary sugar, percentage of

dietary carbohydrate, total dietary sugar and fructose intake) and

HDL cholesterol was observed. Stepwise multiple regression analysis

revealed glycemic load accounted for 21.1 percent of the variation in

HDL cholesterol.

 

The researchers concluded glycemic load appears to be an important

independent predictor of HDL cholesterol in youth and noted dietary

restrictions without attention to glycemic load could unfavorably

influence blood lipids.

Hi Alon,

 

A diet that avoids hyperglycemia and glycosylation of LDLs. To me it

looks like vegetable soup cooked with small amounts of meat and a few

fresh fruits per day. I'd accept Lance Armstrong's trainers diet

with calorie breakdown as 70% from complex carb (cooked vegetables),

15% from protein and 15% from fat ... assuming use of whole and

unrefined foods (no added flour, refined sugars, fats/oils). The

fresh fruit and overall calorie input would have to be in proportion

to activities (calorie output). At least a 300-400 calorie aerobic

output in the AM would greatly facilitate health and would increase

the menu options. That would be an hour hike in the park or riding

your bike to and from work depending on the distance. You could take

the scenic route if you place of work was too close. I average 5,600

calories of weekly exercise throughout the year (~800/day) and yet

have not had to resort to grains. Lance and Tour riders I'm told

burn 6,000 calories per day. But then, that's their job. Like you, I

have to work indoors and must carefully schedule my fun in the sun

(or like today in the rain). Many a physiologist says the most

stressful thing we do is metabolize food. Soup is easy on the body.

Additionally stressful is dealing with the " errors " that bring about

hyperglycemia. Soups of non-starchy vegetables and small amounts of

meat avoid such errors. There are other menu options for those with

a bit of talent and time to cook.
