Lethbridge Herald, The (Newspaper) - November 6, 1974, Lethbridge, Alberta WednMday, November 6, 1974-THE LETHBRIDGE HERALD-47 Yogurt key to heart trouble? NAIROBI (Reuter) Twenty-four Kenyan Masai tribesmen, eating and drinking as much as they can hold, have given scientists a pointer as to how to reduce the level of cholesterol in the blood, with important implications for research into heart disease. Western man who over-eats food rich in cholesterol suf- fers from furring up of the degenerative heart diseases to such an extent it is almost an epidemic in North America. But the Masai, who live on a cholesterol-rich diet of milk and meat have been known for years to be almost free of heart disease. Most experts believed this was because of the enormous amount of exercise these nomadic cattlemen take, with young Masai covering anything up to 25 miles a day. But through a total accident a team of medical research- ers, looking for something completely different, believe they have stumbled over the secret of the Masi's arteries- yogurt. Provide link For years health faddists have advocated yogurt for a long and active life, but no scientific reason has ever been ad- vanced for this. Now the Masai have provided a link between cholesterol and yogurt which may provide a key to a real heart disease breakthrough. The research has been carried out by Dr. George Mann of Vanderbilt University in Tennessee and Dr. Anne Spoerry, of the Kenyan flying doctor service and the African Medical Research Foundation. Dr. Mann came to East Africa a year ago looking for a group of people living in a completely natural background and unpolluted with modern food additives. His purpose was research into the effect of the substance which makes it easier to mix oil and water and which is added to many foods such as mayonnaise, chocolate, ice cream and cakes and is contained in detergents. Research with animals had suggested that surfactants add- ed to diet increased blood cholesterol levels, so Dr. Matin wanted a group of people for research who had none in their diet. With the help of the Kenyan flying doctor team he per- suaded 24 young Masai men to take part in the experiment in return for all the meat and milk they could eat plus one cow each at the end. Control group The young men were divided into two groups, one of which had surfactants added in small quantities to their diet of meat and fermented whole sort of homemade yogurt which the Masai prefer to fresh milk. Unfortunately for Drs. Mann and Spoerry however, things did not go quite right. First of all the young men started to put on weight, which itself upsets the blood cholesterol level and threatened to invalidate the experimental data. Secondly, the Masai became extremely anxious to get back home. It was therefore decided to end the experiment after only three weeks on what looked like an unsuccessful note. Dr. Mann returned to the United States and had the results analysed. That was when the surprise came, for the results showed that the men in both groups had lower cholesterol levels in their blood than when the experiment started. Since they had been eating about twice as much as they usually do and were taking less exercise during the ex- periment, there appeared to be only one logical explanation: the more yogurt you eat the lower your cholesterol level. The Masai were consuming up to eight litres (1.7 gallons) of yogurt a day during the experimental period and by all the rules their cholesterol level should have gone up. Found minimum Dr. Mann has since conducted experiments on Americans and has found that if a minimum of 3V2 pints of yogurt a day is consumed, it appears to have a definite and consistent effect on cholesterol levels. Now research is in progress to discover why this is and to isolate whatever it is in yogurt that has the beneficial effect. Dr. Mann believes it may be that the bacteria which ferments the milk and turns it into yogurt may produce a a fatty stops the body's own production of cholesterol in the liver. The full facts have yet to be establishes but it does appear that the hearty appetites of 24 Masai men may have started something which will benefit the whole of humankind.
