So that argument is indeed bogus."<br /><br />This is incorrect. Married Bantu men have exceptionally low levels of physical activity - almost all physical work is done by women. <br /><br />The type of physical activity is also very important. Only <b>regular sustained rhythmic activity</b> like brisk walking exercise the heart. Activities like horticulture or infrequent lifting have little or no cardio-protective effect.blogbloghttps://www.blogger.com/profile/18029519906193388609noreply@blogger.comtag:blogger.com,1999:blog-13260386.post-61795900770470524002009-09-05T20:59:55.290-05:002009-09-05T20:59:55.290-05:00There entire Lipid Hypothesis of heart disease is ...There entire Lipid Hypothesis of heart disease is utter nonsense. The LDL:HDL Ratio and TC are completely meaningless measures. It doesn't matter whether your TC is 3mmol/L or 8mmol/L<br /><br /><br />Only three things have ever been shown to reduce CHD:<br /><br />a) adequate omega 3, vitamin C and selenium intake; <br /><br />b) high levels of of moderate physical activity and<br /><br />C) low levels of psychosocial stress.<br /><br />It is very unlikely that diet has <b>any</b> role at all in CHD. For example Zulu(Bantu) cane cutters examined by Dr TL Cleave had no CHD or obesity on a sugar-laden diet of ~90% carbohydrate. <br /><br />The Zulu have low CHD because they walk 25km each day not because of their diet.blogbloghttps://www.blogger.com/profile/18029519906193388609noreply@blogger.comtag:blogger.com,1999:blog-13260386.post-42930574122087915042008-06-12T11:01:00.000-05:002008-06-12T11:01:00.000-05:00But the Masai do suffer from extensive CHD.I'll le...<I>But the Masai do suffer from extensive CHD.</I><BR/><BR/>I'll let the paper you cite data speak for itself:<BR/><BR/>"We examined 600 genetically genuine Masai with clinical methods, including 350 men over the age of 40, and found very little evidence of cardiovascular disease.(6) We have found only one Masai man with unequivocal ECG evidence of an infarction.<BR/><BR/>Reference 6 is Mann et al, Cardiovascular Disease in the Masai; J Atheroscler Res 4: 289-312, 1964<BR/><BR/>Later in the introduction - "Do the Masai not develop atherosclerosis or do they have it but remain immune to occlusive disease because of some other protective circumstance? The question was answered with autopsy material collected over a five-year period. The Masai do have atherosclerosis but the are almost immune to occlusive disease.<BR/><BR/>The paper you cite is the results of fifty autopsies of hearts and vessels. <BR/><BR/>Ten of the 50 heart specimens showed evidence of disease or anomalies. Four were scarred in a manner typical of rheumatic carditis (rheumatic fever, not heart disease per se). Two showed evidence of syphilitic aortistis adn two had extensive pericarditis, probably causing their deaths. Three hearts with anomalous patterns of coronary vessels were found but none in none was their evidence of myocardial disease.<BR/><BR/>In reviewing table 2, the causes of death of the 50 were: 15 due to combat wounds, 13 due to infection, 8 due to CV renal, 6 due to accidents, 3 due to maligancy, 2 due to instestinal obstruction, 2 due to suicide and 1 due to diabetic coma.<BR/><BR/>Of the ten noted to have abnormalities found:<BR/><BR/>4 were due to rheumatic heart disease, a condition following rheumatic fever; 2 were symphilitic aortitis, a pathological state of the aorta associated with the tertiary stage of syphilis infection; 2 were pericarditis-constrictive, cause unknown, but commonly caused by tuberculosis infection and/or other inflammatory infection; and two (along with one with rheumatic heart disease) had anamalous coronary vessels, with the two not related to rheumatic heart disease being congenital defects - both coronary arteries arising on the left and one absent a right coronary artery.<BR/><BR/>Later, in the discussion section, the researchers note, "We find the Masai vessels do show extensive atherosclerosis; they show coronary intimal thickening which is equal to that seen in elderly Americans. The unique anatomical feature of the Masai is that the coronary vessels enlarge with age so that the lumina are not compromised by intimal thickening.<BR/><BR/>They continue, "The three noteworthy factors to be considered in the Masai immunity to CHD are fitness, the hypothetical noxious dietary agent which is unidentified and the fibrous capping explanation which proposed that 15 years of muranhood in young adults allows early lesions to be capped and this gives immunity to subsequent progression.".https://www.blogger.com/profile/09224160356421549054noreply@blogger.comtag:blogger.com,1999:blog-13260386.post-4832415890565021552008-06-11T23:33:00.000-05:002008-06-11T23:33:00.000-05:00But the Masai do suffer from extensive CHD.

George Mann, one of the original researchers that popularized the Masia and a great doubter of the lipid hypothesis, acutally preformed autopsies on Masia men and discovered extensive blood vessel disease. Luckily they were proteced by their exceptional large cornaary arteries (due their genetics and large volumne of medium intensity aerobic exercise).<BR/><BR/>Regards<BR/>Randy<BR/><BR/>Here's the ref:<BR/><BR/>ATHEROSCLEROSIS IN THE MASAI1 <BR/>GEORGE V.

Atherosclerosis in the Masai. Am J Epidemiol 95: 26–37, 1972.–The hearts and aortae of 50 Masai men were collected at autopsy. These pastoral people are exceptionally active and fit and they consume diets of milk and meat. The intake of animal fat exceeds that of American men. Measurements of the aorta showed extensive atherosclerosis with lipid infiltration and fibrous changes but very few complicated lesions. The coronary arteries showed intimal thickening by atherosclerosis which equaled that of old U.S. men. The Masai vessels enlarge with age to more than compensate for this disease. It is speculated that the Masai are protected from their atherosclerosis by physical fitness which causes their coronary vessels to be capacious. <BR/><BR/><BR/>atherosclerosis; autopsy; cholesterol; coronary artery disease; diet; exercise<BR/><BR/><BR/><BR/>--------------------------------------------------------------------------------<BR/>1 From the Nutrition Division, vanderbilt University, Nashville, Tennessee 37203 (G.

If they needed to offset with very high energy expenditure levels, then they must have been consuming very high calorie diets, no? (I realize this is kind of obvious, I just feel that it deserves to be underlined.)<BR/> So dietary fat is good for you, as long as you burn it?

So if you compare such a diet to a western diet, it's going to come up smelling like roses. But lowfat diets do NOT look so great when compared head to head with low carb diets. And regarding activity level of Masai...I'm sure the rural Bantu also have a high activity level. So that argument is indeed bogus.Anonymousnoreply@blogger.com
