The concept of positive health Positive health requires a knowledge of man’s primary constitution (what today we would call genetics) and of the powers of various foods, both those natural to them and those resulting from human skill (today’s processed food). But eating alone is not enough for health. There must also be exercise, of which the effects must likewise be known. The combination of these two things makes regimen, when proper attention is given to the season of the year, the changes of the winds, the age of the individual and the situation of his home. If there is any deficiency in food or exercise the body will fall sick. ~Hippocrates

The Mediterranean Diets Although Greece and the Mediterranean countries are usually considered to be areas of medium-high death rates (14.0-18.0 per 1000 inhabitants), death rates on the island of Crete have been below this level continuously since before 1930. No other area in the Mediterranean basin has had as low a death rate as Crete, according to data compiled by the United Nations in their demographic yearbook for 1948. It was 11.3-13.7 per 1000 inhabitants before World War II and about 10.6 in 1946-1948. Cancer and heart disease caused almost three times as many deaths proportionally in the United States as in Crete. The diet of Crete represents the traditional diet of Greece before 1960.

Early protection against sudden death by ω3 polyunsaturated fatty acids after myocardial infarction: Time-course analysis of the results of the Gruppo Italiano per lo Studio della Sopravvivenza nell’Infarto Miocardico (GISSI)-Prevenzione Marchioli R., Barzi F., Bomba E. et al. Circulation 2002; 105: 1897-1903. 11,323 patients were randomly assigned to supplements of omega-3 PUFAs 850 mg/d- ratio of EPA:DHA = 2.1 Vitamin E = 300 mg/d Both omega-3 and vitamin E None (control) On top of optimal pharmacological treatment, lifestyle advice Survival curves for omega-3 PUFA treatment diverged early after randomization and total mortality was significantly lowered after 3 months of treatment A similar significant, although delayed pattern after 6 to 8 months of treatment was observed for cardiovascular, cardiac and coronary death

Probability measurements represent relative risk (95% confidence interval). Reprinted, with permission, from Marchioli et al. MI = myocardial infarction.
Early protection against sudden death by ω3 polyunsaturated fatty acids after myocardial infarction: Conclusion The early effect of low dose 850 mg/d omega-3 PUFAs on total mortality and sudden death supports the hypothesis of an antiarrhythmic effect of omega-3 fatty acids. Such a result is consistent with the wealth of evidence coming from laboratory experiments on isolated myocytes, animal models, epidemiological and clinical studies.

Metabolic Syndrome The prevalence of metabolic syndrome in the U.S. has been increasing and is particularly high for older adults and certain ethnic groups. Hispanics have the highest reported prevalence of metabolic syndrome, and are more likely to be affected by type 2 diabetes than non-Hispanic whites.
The Components of the Metabolic Syndrome Abdominal Obesity waist circumference > 102 cm in Men and > 88 cm in Women Dyslipidemia Increase Trigylcerides > 150 mg/dl Decrease HDL < 40 mg/ dl in Men and < 50 mg/dl in Women Hypertension Blood Pressure > 130/85 mmHg Fasting Hyperglycemia 100 mg/dl
Omega-3s and Insulin Sensitivity Dietary intake of omega-3 fatty acids have insulin-sensitivity actions in adipose tissue and liver and improve insulin sensitivity. Genes involved in insulin sensitivity (PPAR ), glucose transport (GLUT-2/GLUT-4) and insulin receptor signaling (IRS-1/IRS-2) are upregulated by omega-3 fatty acids. Moreover omega-3 fatty acids increase adiponectin, an anti-inflammatory and insulin- sensitizing adipokine, and induce AMPK phosphorylation, a fuel-sensing enzyme and a gate keeper of the energy balance.
ω-6/ω-3 ratio in chronic diseases Simopoulos, AP. Exp Biol Med (Maywood). 2008 Jun; 233(6):674-88 In the secondary prevention of cardiovascular disease, a ratio of 4/1 was associated with a 70% decrease in total mortality. A ratio of 2.5/1 reduced rectal cell proliferation in patients with colorectal cancer, whereas a ratio of 4/1 with the same amount of omega-3 PUFA had no effect. The lower omega- 6/ omega-3 ratio in women with breast cancer was associated with decreased risk.
ω-6/ω-3 ratio in chronic diseases Simopoulos, AP. Exp Biol Med (Maywood). 2008 Jun; 233(6):674-88 A ratio of 2-3/1 suppressed inflammation in patients with rheumatoid arthritis, and a ratio of 5/1 had a beneficial effect on patients with asthma, whereas a ratio of 10/1 had adverse consequences. These studies indicate that the optimal ratio may vary with the disease under consideration. This is consistent with the fact that chronic diseases are multigenic and multifactorial. Therefore, it is quite possible that the therapeutic dose of omega-3 fatty acids will depend on the degree of severity of disease resulting from the genetic predisposition.
ω -3’s in Development Maternal intake of W-3’s during pregnancy and lactation may favor the later mental development of children (Helland et al. Pediatrics. 2003 Jan;111:39-44) important in visual and cognitive development
Metabolic programming of long-term outcomes due to fatty acid nutrition in early life Understanding of the importance of dietary fatty acids has grown beyond a simple source of energy to complex roles in regulating gene expression and cell and intracellular communication. This is important because the metabolic and neuroendocrine environment of the fetus and infant plays a key role in guiding the set point of neural receptors that regulate energy homeostasis and expression of genes that control energy storage and oxidation. Early deviations in these pathways have the potential to lead to lasting adaptations, termed metabolic programming, which may combine to increase the risk of metabolic syndrome in later life. The quality of fatty acids in human diets has undergone major changes in the last 50 years, characterized by an increase in ω-6 and decrease in ω-3 fatty acids. Evidence is accumulating to support the concept that the maternal intake of ω-6 and ω-3 fatty acids in gestation and lactation, possibly involving both excess ω-6 and inadequate ω-3 fatty acids, can impact the developing infant tissue lipids and neuroendocrine and metabolic pathways relevant to metabolic programming. Further work is needed to understand the needs for different ω-6 and ω-3 fatty acids during fetal and infant life, and their roles with respect to development of energy homeostasis and metabolism.
ω -3’s in Healthy Subjects 33 healthy subjects, 13 M, 20 F, 22-51 yrs (mean =33 ±7yrs) Subjects were tested at the beginning of the experiment and after 35 days. Supplemented with 4 grams of fish oil (1.60g EPA + 0.80 DHA + 0.4g of other W-3’s). Control consisted of 4g olive oil (indistinguishable by packaging, shape or taste). Fontani et al.

Mediterranean-inspired diet: Conclusion A Mediterranean-inspired diet (MID) reduces the number of platelets and leukocytes and VEGF concentrations in healthy subjects. This may be linked to higher serum concentrations of omega-3 fatty acids, which promote a favorable composition of phospholipids.

A Reduced Omega-6/Omega-3 Fatty Acid Dietary Ratio Increases Adiponectin Concentration and Fatty Acid Oxidation in Healthy Subjects Guebre-Egziabher et al. carried out a ten week dietary intervention in 17 healthy subjects. The dietary intervention decreased the LA/ALA ratio from 32.2 (s.d. 3.7) versus post-intervention 2.2 (s.d. 0.1). Guebre-Egziabher F, et al.

A Reduced Omega-6/Omega-3 Fatty Acid Dietary Ratio Increases Adiponectin Concentration and Fatty Acid Oxidation in Healthy Subjects Dietary intake, euglycemic hyperinsulinemic clamp, indirect calorimetry, lipid profile, hormones, inflammatory markers and erythrocyte membrane fatty acid composition were measured before and at the end of the intervention period. Comparisons are between baseline and post-intervention levels. Guebre-Egziabher F, et al. Nutritional intervention to reduce the n-6/n-3 fatty acid ratio increases adiponectin concentration and fatty acid oxidation in healthy subjects. Eur J Clin Nutr 2007.
A Reduced Omega-6/Omega-3 Fatty Acid Dietary Ratio Increases Adiponectin Concentration and Fatty Acid Oxidation in Healthy Subjects There were significant decreases in glucose oxidation rate, in LDL and TNF-a with a non significant decrease in IL-6 and CRP. Most importantly, there was a significant increase in adiponectin and fatty acid oxidation, which may explain the decrease in adipose tissue noted by Couet et al., and the weight loss noted by Hill et al. with increased intakes of dietary omega-3 fatty acids. Guebre-Egziabher F, et al. Nutritional intervention to reduce the n-6/n-3 fatty acid ratio increases adiponectin concentration and fatty acid oxidation in healthy subjects. Eur J Clin Nutr 2007.
A Reduced Omega-6/Omega-3 Fatty Acid Dietary Ratio Increases Adiponectin Concentration and Fatty Acid Oxidation in Healthy Subjects The Guebre-Egziabher et al. study showed that a decreased omega-6/omega-3 fatty acid ratio can be achieved with simple dietary counseling, resulting in multiple potentially favorable effects on the metabolic and inflammatory profiles of the subjects.

Although the recommendation is for AI, the Working Group felt that there is enough scientific evidence to also state an upper limit (UL) for LA of 6.67 g/d based on a 2000kcal diet or of 3.0% of energy. 2. For pregnant and lactating women, ensure 300 mg/d of DHA. 3.Except for dairy products, other foods under natural conditions do not contain trans-FA. Therefore, the Working Group does not recommend trans-FA to be in the food supply as a result of hydrogenation of unsaturated fatty acids or high temperature cooking (reused frying oils). 4.Saturated fats should not comprise more than 8% of energy. 5. The Working Group recommended that the majority of fatty acids are obtained from monounsaturates. The total amount of fat in the diet is determined by the culture and dietary habits of people around the world (total fat ranges from 15-40% of energy) but with special attention to the importance of weight control and the reduction of obesity.

The formula/ diet comparison described here is patterned on infant formula studies in Western countries. 2.The Working Group endorsed the addition of the principal long chain polyunsaturates, AA and DHA, to all infant formulas. 3.EPA is a natural constituent of breast milk, but in amounts more than 0.1% in infant formula may antagonize AA and interfere with infant growth.

Recommendations The time has come for Greeks to return to their traditional composition of the food supply. The scientific evidence for a balanced omega-6/omega-3 fatty acid ratio as it was prior to 1960 is robust.
Recommendations Changing from the French or Swedish diets to one that is similar to the traditional diet of Greece (Greek Mediterranean diet) has been shown to be possible and to decrease cardiometabolic risk factors and inflammation.
Recommendations Greece should take a leadership position in establishing 1 or 2 Centers on Genetics Nutrition and Fitness for Health to combat obesity and chronic non-communicable diseases and define the healthy diet for the Greek population through studies on Genetics, Physiology, Metabolism, Nutrition and Physical Activity, thus implementing the Concept of Positive Health as articulated by Hippocrates in 5 th Century BC.
