Recommended Posts

what does everone think about egg yolks, i.e is too many bad for you, will eating shitloads of them cause me to have a stroke while im in the middle of a set of squats. below is something i found on another forum

Fernandez ML. Dietary cholesterol provided by eggs and plasma lipoproteins in healthy populations. Curr Opin Clin Nutr Metab Care. 2006 Jan;9(1):8-12.

PURPOSE OF REVIEW: Extensive research has not clearly established a link between egg consumption and risk for coronary heart disease. The effects of egg intake on plasma lipids and low-density lipoprotein (LDL) atherogenicity in healthy populations need to be addressed. RECENT FINDINGS: The lack of connection between heart disease and egg intake could partially be explained by the fact that dietary cholesterol increases the concentrations of both circulating LDL and high-density lipoprotein (HDL) cholesterol in those individuals who experience an increase in plasma cholesterol following egg consumption (hyperresponders). It is also important to note that 70% of the population experiences a mild increase or no alterations in plasma cholesterol concentrations when challenged with high amounts of dietary cholesterol (hyporesponders). Egg intake has been shown to promote the formation of large LDL, in addition to shifting individuals from the LDL pattern B to pattern A, which is less atherogenic. Eggs are also good sources of antioxidants known to protect the eye; therefore, increased plasma concentrations of lutein and zeaxanthin in individuals consuming eggs are also of interest, especially in those populations susceptible to developing macular degeneration and eye cataracts. SUMMARY: For these reasons, dietary recommendations aimed at restricting egg consumption should not be generalized to include all individuals. We need to acknowledge that diverse healthy populations experience no risk in developing coronary heart disease by increasing their intake of cholesterol but, in contrast, they may have multiple beneficial effects by the inclusion of eggs in their regular diet.

Sounds like you know more about this than me, but here's my opinion, for what it's worth...

I'd call 20 eggs a week (3 a day) an average-to-high amount. Perhaps not too extreme for bodybuilders, but certainly more than most people would eat. The majority of the egg's fat is unsaturated - but as to the overall effect on your cholesterol levels, I just don't know. I think there have been some suggestions that eggs may in fact decrease LDL levels (the "bad cholesterol", if you like...) - but I think the jury's still out on that one.

What's prompting your cholesterol checkup? Let us know how you get on. :)

  • 3 weeks later...
  • 3 months later...

total cholesterol 5.9mmol/L target <5.2

triglyceride 1.46mmol/L ideally <1.8

HDL cholesterol(good) 1.5mmol/L (over 1.0)

LDL cholesterol (bad) 3.7mmo/L (<3.0)

total/HDL chol: 4.0 (under 5.0)

i am told there is no need for alarm, these levels are quite healthy, i will have another checkin 6 months time and monitor any changes, for now i might cut back the amount of k fry, bks and maccas, but i wont be slowing on the yolk intake :grin:

Here's a good read....

Cholesterol in perspective

Since cholesterol is a key component in the diet-heart controversy, let's take a closer look at this substance. What is it? Where does it come from? What does it do in the body?

Cholesterol is a complex fatty substance found in every living cell. We cannot live without it. It provides the building blocks from which the body makes its own supply of sex and adrenal hormones. Cholesterol can also be converted to vitamin D in our body and used for the calcification of bones and teeth.

Our body is capable of making its own supply of cholesterol. In fact, most of the cholesterol found in our body is made there; only part of it comes from the food we eat. The liver and intestines are the primary sites where it is manufactured. Overproduction of cholesterol may be the most important factor contributing to arteriosclerosis, a form of hardening of the arteries. Probably 90 percent of all cases of strokes and heart attacks are due to arteriosclerosis.

Some research findings

Numerous dietary studies have been undertaken to determine the effect of cholesterol intake on the level in the body.

Thirteen patients at the Highland Hospital in Oakland, California were fed the equivalent in egg yolks of that found in 15 eggs per day for a 3 week period. The serum cholesterol did not increase significantly in any except two bedridden, obese patients. Four of the 7 ambulatory patients in the study actually showed a slight decrease in serum cholesterol.

In the Ireland-Boston Heart Study the researchers followed 600 Irishmen between the ages of 30 and 60 who had lived in Boston for 10 or more years and their brothers who had never left the old country. The Irish brothers ate about twice as many eggs as their American brothers--averaging over 14 per week. Yet, the Irish brothers had lower levels of cholesterol in their bloodstream, and their hearts were rated from 2 to 6 times healthier. The same Harvard doctor examined both groups. More physical exercise was given as a possible reason for this difference.

Dr. Robert Itchiness, a cardiologist in New York city specializing in metabolic disorders, has treated over 8,000 patients. He lowered the serum cholesterol markedly in 63 percent of his patients with a diet high in meat, milk, and eggs. Dr. Itchiness believes that 95 percent of all heart trouble is associated with high serum triglycerides and attributes this to the staggering increase in sugar consumption--up from 7 pounds per person in 1840 to over 100 pounds today.

Probably the most comprehensive research project in the diet-heart field was the Framingham Heart Program which began in 1948 in a community 30 miles west of Boston. Five thousand people were involved over a period of 20 years. Their diets were not changed, but what each person ate was recorded. Four risk factors associated with coronary heart disease were identified:

* High blood pressure

* Excess cholesterol in the blood

* Cigarette smoking

* Obesity

The report issued after the Framingham Study was concluded said: "There is no suggestion of any relationship between diet and the subsequent development of coronary heart disease in the study group despite a distinct elevation of serum cholesterol in those developing coronary heart disease."

Changes in diet

Some rather striking changes have occurred in the average American's diet during the past 15 years. Consumption of vegetable oils has increased markedly while consumption of animal fats has declined. Per capita consumption of eggs, butter, and fat meats has declined. In spite of these shifts, cardiovascular disease has increased. This suggests other risk factors are playing an increasingly important role. Nevertheless, many in the medical profession still recommend major dietary changes for the entire population.

In conclusion

Little doubt exists that high blood serum cholesterol levels are related to higher incidence of heart disease. But there is considerable variation in individual's ability to handle cholesterol. Most people appear to be able to regulate the production of cholesterol in their body according to dietary changes; others cannot. For those who cannot, special precautions need to be taken. But a radical dietary change for the entire population does not seem to be desirable nor warranted.
