Nutrition and cardiovascular (CV) risk: Revisiting the French Paradox The French Paradox is the observation of low coronary heart disease (CHD) death rates despite high intake of dietary cholesterol and saturated fat.

Nutrition and cardiovascular (CV) risk: Revisiting the French Paradox As for the French Paradox, studying the link between dairy intake and CV risk cannot be limited to the impact of saturated fats but should take into account : Other components of dairy products Other dietary intakes Intricate relationships with lifestyle habits

Dairy products and cardiovascular risk

 Varying content of fats  Varying content of Ca, Na, Mg  Varying proteins with varying properties  Wide possibility of recipes with varying content of sugar and fats….. These issues are of particular importance as: Dairy products are so heterogeneous Consumption of dairy product has been associated with

  • ther specific dietary patterns

Suggested mechanisms

Blood pressure lowering effect of calcium

  • direct impact on smooth vascular muscle
  • impact through PTH and vitamin D secretion
  • increased sodium excretion

Blood pressure lowering effect of other components (ACE inhibitor like effect of milk proteins) Intestinal binding of cholesterol and bile acids induced by Ca: formation of intestinal soaps, decreased fat absorption, increased fat excretion leading to decreased blood lipid levels

Conclusion

Higher consumptions of dairy products (milk ++), fruits, vegetables, and cereals were associated with a lower rate

  • f mortality.

More generally diversified dietary patterns were associated with a lower mortality. Clinical trials are lacking to assess the causal impact of dietary patterns on mortality and clinical events. Studies differentiating between low- and high-fat dairy products will be an important issue in the future
