  23. The Seven Countries Study • Goal: To identify CHD risk factors and disease rates • Population: 13,000 men – 40-55 y.o. during a 5 year period in the following Countries: Greece, Italy, (Croatia, Serbia), Japan, Finland, Netherlands, U.S.A. • Methods: RDs stationed in the homes of study subjects measuring everything eaten • Far more accurate than any questionnaire

  24. The Seven Countries StudyConclusions (main points) • This study related saturated fat with CHD • Americans, Dutch and Finns had heart disease rates: • Twice those of Italians • Four times those of the Greeks, Japanese and Yugoslavs • Lowest all cause age specific death rates were found in the Mediterranean region

  25. The Seven Countries StudyConclusions (main points) • This study revealed the universal risk factors for CHD • Blood cholesterol appears to have the strongest correlation • Age • Blood Pressure • Cigarette smoking

  26. Discovery of Different Types of Fat

  28. Some Things are Hard to Prove Scientifically • The effect of mind over body is in the news today • Lifestyle seems to be as important as food • Slower pace, less stress, enjoyment of food • Physical activity and lots of sunshine • Common sense tells us the above are important

  29. Chapter 2

  30. Comparing Notes • How does the Mediterranean diet compare to the guidelines of major health organizations?

  31. American Heart Association • www.americanheart.org • AHA position is updated according to new research • Fat is always a target especially SFA • Three main risk factor for CHD • ↑ blood pressure, ↑ blood lipids, obesity

  32. My Pyramid USDA • http://www.mypyramid.gov/pyramid/index.html

  33. Dietary Guidelines 2005 • Emphasis on weight control and continued importance of physical activity. • Recommendation on dietary fats • trans fats should be as low as possible • saturated fat should be limited. Recommends between • 20 and 35% of daily calories from fat • recognizes potential health benefits of MUFA and PUFA • Urge Americans to limit sugar intake and they stress the benefits of whole grains.

  34. Some things have not changed • It is fine to consume half of our grains as refined starch. • Red meat, poultry, fish, and beans (including soy products) are lumped together. • The recommendation to drink 3 glasses of low-fat milk or eat 3 servings of other dairy per day to prevent osteoporosis ignores the lack of evidence between consumption of dairy and prevention of osteoporosis. It also ignores the possible increases in risk of ovarian cancer and prostate cancer associated with dairy products and the fact that millions of Americans are lactose intolerant
