Food for Thought
If you've been saturated for years with old journalistic cliches about the terrors of fat and protein and the virtues of carbohydrate, try sinking your teeth into these crunchy little thought nuggets. Your physician might find them revealing as well.
• 1991: A Canadian team substituted meat and dairy protein for carbohydrate in the
diets of ten men and women with high cholesterol. The group lowered their total
cholesterol by an average of six and a half percent, lowered their average triglycerides
by twenty-three percent and raised their HDL cholesterol by an average of twelve
percent.
• 1996: The INTERSALT, an international blood pressure study comparing 10,020
men and women in thirty-two countries, found that people with a dietary protein
intake of thirty percent above the average had lower blood pressure than people with
a lower intake of protein.
• 1997: In a twenty-year follow-up of 832 men tracked in the world-famous
Framingham Heart Study, re searchers matched incidence of stroke (there were sixtyone
in all) with dietary intake. The men with the highest intake of dietary fat had the
fewest strokes; the men with the lowest had the most strokes.
1998: A Seattle team analyzed the data from seventeen different population-based
studies that reported the relationship between triglycerides and heart disease. Men
with higher triglycerides had a thirty-two percent increased risk of heart disease;
women with higher levels had a seventy-six percent increased risk.
• 1999: The Harvard Nurses Study did a fourteen year follow-up on 80,082 women,
comparing incidence of heart disease. Findings show that the higher the intake of
protein, the lower the risk of heart disease in this group of women who were 34 to 59
years old at the outset of the study.
