It is increasingly a shameful national embarrassment for the United States to have constructed a billion-dollar cardiac healthcare industry surrounding an illness that does not even exist in more than half of the planet. If you, as a cardiologist or a cardiac surgeon, decided to hang your shingle in Okinawa,[3] the Papua Highlands of New Guinea,[4] rural China,[5] Central Africa,[6] or with the Tarahumara Indians of Northern Mexico,[7] you better plan on a different profession because these countries do not have cardiovascular disease. The common thread is that they all thrive on whole food, plant-based nutrition (WFPBN) with minimal intake of animal products.

Question: Can heart disease be stopped or even reversed?

Answer: Yes. First we must look at the lessons learned from cultures where there is a virtual absence of coronary artery heart disease such as rural China, the Papua Highlands of New Guinea, Central Africa, and the Tarahumara Indians of Northern Mexico. Their nutrition is plant based without oil.

Plant-based nutrition provides us with a pathway to escape the coronary artery disease epidemic. For persons in central Africa, the Papua Highlanders of New Guinea, the Tarahumara Indians of northern Mexico, and inhabitants of rural China as described in the Cornell China Study, coronary disease is essentially non-existent while hypertension, Western malignancies, obesity, and adult onset diabetes are rarely encountered.

The Papua New Guineans

The Papua New Guineans traditionally subsisted on a plant based diet, of which a number of varieties of sweet potatoes typically supplied over 90% of dietary intake. They also grew a number of other crops including corn, as well as sugar cane which was consumed as a delicacy. Pig feasts are organised a few times a year, but at which pork is not consumed in excess of 50 grams. A dietary survey on the Papua New Guineans highlanders estimated that carbohydrate accounted for 94.6% of total energy intake, among the highest recorded in the world. Total energy intake was adequate, however only 3% of energy intake was derived from protein (25g for men and 20g for women), yet there was no evidence of dietary induced protein deficiency or anemia. Furthermore, this surveyed population was described as being muscular and mostly very lean, physically fit and in good nutritional state.^{16 17} They also drank 'soft' water which is considered a risk factor for cardiovascular disease. It was estimated that tobacco was smoked by 73% of males and 20% females. Also, the highlanders spend up to twelve hours a day inside a smoke-filled house due to centrally placed open wood fires with little ventilation and no chimneys in their homes, resulting in a very high exposure to hazardous smoke in this population.¹⁶

Despite cardiac risk factors including high exposure to smoke and soft drinking water, a number of authors observed a great rarity of incidence of atherosclerosis, coronary heart disease and stroke among the traditional Papua New Guineans, but also noted an increase in incidence paralleling the Westernization of the nation. In 1958, Blackhouse reported on autopsies of 724 individuals between 1923 and 1934 and found no evidence of heart attack incidence and only one case of slight narrowing of the coronary arteries. However, it has been suggested that this study was selective as only a small portion of the autopsies were performed on females or the elderly. In 1969, Magarey et al. published a report on the autopsy results of 217 aortas and found a great rarity of atherosclerosis. The authors noted that the prevalence and severity of atherosclerosis was less than had been reported in any previously investigated population.¹⁸ In 1973, Sinnett and Whyte published findings from a survey of 779 highlanders using electrocardiograms among other methods, and found little probable evidence of coronary heart disease, and no clinical evidence of diabetes, gout, Parkinson’s disease, or any previous incidence of stroke.¹⁶

For a population that consumed virtually the highest intake of carbohydrates out of any population to also have virtually the lowest incidence of atherosclerosis and diabetes ever recorded highlights the vital importance of the health properties of specific carbohydrate rich foods. These findings further question certain 'carbohydrate-induced dyslipidemia' hypotheses, emphasized by certain researchers, who perhaps intentionally do not always take the quality of carbohydrate rich foods into careful consideration.¹⁹

In 1900, Sir William MacGregor reported in the Lancet in regards to the observed rarity of cancer among the native Papua New Guineans, asserting that:²⁰

In 1974, Clezy brought to attention the rarity of mortality from colorectal cancer among the Papua New Guineans, for which the observed annual rate per 100,000 was 0.6 for men and 0.2 for women. These rates were 100 fold lower than that of many developed nations during the same time period, although this could have been in part explained by underdiagnosis.¹⁷

Even in more recent statistics after modest changes towards a western diet, the Papua New Guineans still had among the lowest rates of hip fractures in the world, which Frassetto et al. observed was more than 50 fold lower than that of the Scandinavian nations.²¹ Although these researchers ascribed the worldwide differences in rates of hip fractures to the ratio of vegetable to animal protein, evidence from prospective cohort studies and randomized controlled trials, as well as experimental animal models suggests that saturated fat may be at least as great, if not an even greater contributor to poor bone health.^{22 23 24 25 26}
