In certainregions of France, Jean, goodfood and wine, elsewhere in Western World, Joe, fastfood and sweetdrinks. It shows in longevity!
The french paradox: what is the essential factor? The alcoholor the polyphenols? Orboth? • Jean vs. Joe
There are >500 substancesin wine. 35 have cardiovascularaction, 1 of these is resveratrol...
The multiple mechanisms of the polyphenolstogetherwithindividualactionsform a beneficial cascade on the endothelium.
Multiple mechanisms of action of polyphenols “THE BENEFICIAL CASCADE”VASCULAR RELAXATION (NO stimulation / endothelinreduction)+ANTI-INFLAMMATORY+ANTI-CHOLESTEROLEMIC+ ANTI-THROMBOTIC +ANTI-OXIDANT ACTION=Together: VASCULAR PROTECTIVE and ANTI-ATHEROSCLEROTIC
Variousprocessesinvolved in the dysfunction of the endothelium and the earlyatherosclerotic plaque are the sites where the polyphenolsstop inflammation!

FRUIT & VEGETABLE CONSUMPTION AND MORTALITY FROM CARDIOVASCLUAR DISEASE AND CANCER Dose response relationbetweenconsumption and risk of all-causemortality
FRUIT & VEGETABLE CONSUMPTION AND MORTALITY FROM CARDIOVASCulAR DISEASE • 469.551 participants, 6.893 deaths • The average reduction was 4% for each additional serving of 106gr per day for fruit + vegetables, 6% for fruit alone • Threshold at 5 servings of 106gr a day Conclusion: • Higher consumption of fruit and vegetables is associated with significantly lower risk of cardiovascular mortality!

!MULTIFACTORIAL DISEASE DESERVES A MULTIFACTORIAL SOLUTION! Smoking / Inflammation / Dyslipidaemia / Hypertension / Dysglycaemia Proinflammatorycytokineslead to endothelialdysfunctionand atherosclerosis(e.g. Vcam, MCP-1, MIF, IL-6, TNFα, CD40L, CRP) So No smoking, physical activity 5x week Vegetables, red fruits, nuts, 600gr per day Oilyfish 3x week No red meat! Oliveoil 4 tbs/d Red wine 4 glassesday + or 500mgm In-Vino-Veritas + Lipid core ‘Messenger’ cytokine IL-6 Fibrinogen, PAI-1 Triglyceridemia OX_LDL Atheroma C-reactiveprotein Endothelial Dysfunction So, strictlyadhere to the MediterraneanDietor supplement a varieddietwith “food medicines” such as polyphenols and PUFA’s.

6glasses of a specific red wine (~280ml) = 500 à 1000mg polyphenols are neededfordailydose • OR • In 500mg powderedRWPC’sIn-Vino-Veritasfor €1,25/day
This is FANTASTIC! • It is like the birth of a new “vitamin” – justlikeVitamin B6, Vitamin C fromnaturalsources– hithertoignored (exceptby the • Mediterraneanpeople)
