Omega-3 Fatty Acids and Antioxidants in Edible Wild Plants
SIMOPOULOS,ARTEMIS P;
Biological Research , 2004, DOI: 10.4067/S0716-97602004000200013
Abstract: human beings evolved on a diet that was balanced in the omega-6 and omega-3 polyunsaturated fatty acids (pufa), and was high in antioxidants. edible wild plants provide alpha-linolenic acid (ala) and higher amounts of vitamin e and vitamin c than cultivated plants. in addition to the antioxidant vitamins, edible wild plants are rich in phenols and other compounds that increase their antioxidant capacity. it is therefore important to systematically analyze the total antioxidant capacity of wild plants and promote their commercialization in both developed and developing countries. the diets of western countries have contained increasingly larger amounts of linoleic acid (la), which has been promoted for its cholesterol-lowering effect. it is now recognized that dietary la favors oxidative modification of low density lipoprotein (ldl) cholesterol and increases platelet response to aggregation. in contrast, ala intake is associated with inhibitory effects on the clotting activity of platelets, on their response to thrombin, and on the regulation of arachidonic acid (aa) metabolism. in clinical studies, ala contributed to lowering of blood pressure, and a prospective epidemiological study showed that ala is inversely related to the risk of coronary heart disease in men. dietary amounts of la as well as the ratio of la to ala appear to be important for the metabolism of ala to longer-chain omega-3 pufas. relatively large reserves of la in body fat, as are found in vegans or in the diet of omnivores in western societies, would tend to slow down the formation of long-chain omega-3 fatty acids from ala. therefore, the role of ala in human nutrition becomes important in terms of long-term dietary intake. one advantage of the consumption of ala over omega-3 fatty acids from fish is that the problem of insufficient vitamin e intake does not exist with high intake of ala from plant sources.
Omega-3 Fatty Acids and Antioxidants in Edible Wild Plants
ARTEMIS P SIMOPOULOS
Biological Research , 2004,
Abstract: Human beings evolved on a diet that was balanced in the omega-6 and omega-3 polyunsaturated fatty acids (PUFA), and was high in antioxidants. Edible wild plants provide alpha-linolenic acid (ALA) and higher amounts of vitamin E and vitamin C than cultivated plants. In addition to the antioxidant vitamins, edible wild plants are rich in phenols and other compounds that increase their antioxidant capacity. It is therefore important to systematically analyze the total antioxidant capacity of wild plants and promote their commercialization in both developed and developing countries. The diets of Western countries have contained increasingly larger amounts of linoleic acid (LA), which has been promoted for its cholesterol-lowering effect. It is now recognized that dietary LA favors oxidative modification of low density lipoprotein (LDL) cholesterol and increases platelet response to aggregation. In contrast, ALA intake is associated with inhibitory effects on the clotting activity of platelets, on their response to thrombin, and on the regulation of arachidonic acid (AA) metabolism. In clinical studies, ALA contributed to lowering of blood pressure, and a prospective epidemiological study showed that ALA is inversely related to the risk of coronary heart disease in men. Dietary amounts of LA as well as the ratio of LA to ALA appear to be important for the metabolism of ALA to longer-chain omega-3 PUFAs. Relatively large reserves of LA in body fat, as are found in vegans or in the diet of omnivores in Western societies, would tend to slow down the formation of long-chain omega-3 fatty acids from ALA. Therefore, the role of ALA in human nutrition becomes important in terms of long-term dietary intake. One advantage of the consumption of ALA over omega-3 fatty acids from fish is that the problem of insufficient vitamin E intake does not exist with high intake of ALA from plant sources.

Dietary Omega-3 Fatty Acid Deficiency and High Fructose Intake in the Development of Metabolic Syndrome, Brain Metabolic Abnormalities, and Non-Alcoholic Fatty Liver Disease
Artemis P. Simopoulos
Nutrients , 2013, DOI: 10.3390/nu5082901
Abstract: Western diets are characterized by both dietary omega-3 fatty acid deficiency and increased fructose intake. The latter found in high amounts in added sugars such as sucrose and high fructose corn syrup (HFCS). Both a low intake of omega-3 fatty acids or a high fructose intake contribute to metabolic syndrome, liver steatosis or non-alcoholic fatty liver disease (NAFLD), promote brain insulin resistance, and increase the vulnerability to cognitive dysfunction. Insulin resistance is the core perturbation of metabolic syndrome. Multiple cognitive domains are affected by metabolic syndrome in adults and in obese adolescents, with volume losses in the hippocampus and frontal lobe, affecting executive function. Fish oil supplementation maintains proper insulin signaling in the brain, ameliorates NAFLD and decreases the risk to metabolic syndrome suggesting that adequate levels of omega-3 fatty acids in the diet can cope with the metabolic challenges imposed by high fructose intake in Western diets which is of major public health importance. This review presents the current status of the mechanisms involved in the development of the metabolic syndrome, brain insulin resistance, and NAFLD a most promising area of research in Nutrition for the prevention of these conditions, chronic diseases, and improvement of Public Health.
Bellagio Report on Healthy Agriculture, Healthy Nutrition, Healthy People
Artemis P. Simopoulos,Peter G. Bourne,Ole Faergeman
Nutrients , 2013, DOI: 10.3390/nu5020411
Abstract: The Bellagio Report on Healthy Agriculture, Healthy Nutrition, Healthy People is the result of the meeting held at the Rockefeller Foundation Bellagio Center in Lake Como, Italy, 29 October–2 November 2012. The meeting was science-based but policy-oriented. The role and amount of healthy and unhealthy fats, with attention to the relative content of omega-3 and omega-6 fatty acids, sugar, and particularly fructose in foods that may underlie the epidemics of non-communicable diseases (NCD’s) worldwide were extensively discussed. The report concludes that sugar consumption, especially in the form of high energy fructose in soft drinks, poses a major and insidious health threat, especially in children, and most diets, although with regional differences, are deficient in omega-3 fatty acids and too high in omega-6 fatty acids. Gene-nutrient interactions in growth and development and in disease prevention are fundamental to health, therefore regional Centers on Genetics, Nutrition and Fitness for Health should be established worldwide. Heads of state and government must elevate, as a matter of urgency, Nutrition as a national priority, that access to a healthy diet should be considered a human right and that the lead responsibility for Nutrition should be placed in Ministries of Health rather than agriculture so that the health requirements drive agricultural priorities, not vice versa. Nutritional security should be given the same priority as food security.

Reduplication and doubling contrasted: implications for the structure of the DP and the AP
Artemis Alexiadou
Linguística : Revista de Estudos Linguísticos da Universidade do Porto , 2010,
Abstract: This paper examines adjectival reduplication in Chinese which is contrasted with determiner doubling in Germanic. It shows that two superficially different phenomena in two genetically unrelated languages are sensitive to similar properties. Both environments support an analysis of adjectives in terms of restrictive relative clauses and strengthen the case for decomposing the adjective
