New studies on the Mediterranean diet confirm its effectiveness for chronic disease prevention

September 08, 2008

Scientists of the Instituto de Nutrición y Tecnología de los Alimentos (Institute of Nutrition and Food Technology) of the University of Granada (UGR, Spain) have been doing research into the positive effects of Mediterranean diet's ingredients on health.

Among these works, there is a new research line about pancreatic cancer cells. Emilio Martínez de Victoria Muñoz, director of the Institute, points out that in the study 'Influence of the ingredients of the Mediterranean diet on a cell line on pancreatic cancer cells' (UGR-Junta de Andalucía) they have manipulated the composition of the cell membrane providing olive oil, fish oil or an antioxidant typical of olive oil, analysing how such cells defend themselves from the aggressions which cause pancreatic alterations".

The objective is to expose olive oil compounds (such as oleic acid) and fruit and vegetable antioxidants to "membranes of a pancreatic cancer cell line in such a way that they become more or less resistant to harmful stimulus which cause diseases such as cancer or pancreatitis".

This way, the research work intends to correlate the composition of cell membranes with more or less resistance to suffering from different types of disease. The conclusions suggest that feeding and changes in membrane composition affect cell function and can therefore influence the prevention of certain diseases.

Preventive feeding

The researchers' hypothesis "starts from considering feeding as a preventive action of the development of chronic diseases, which are the first cause of mortality and morbidity in the world at present: chronic or not contagious diseases such as cardiovascular diseases, cancer, diabetes, hypertension or osteoporosis".

Recent studies of the World Health Organization have pointed out as development factors of chronic diseases (such as obesity, diabetes or cardiovascular diseases) the combination of bad feeding practices, the lack of exercise and unhealthy habits (such tobacco consumption or excessive alcohol).

According to Martínez de Victoria, who pointed it out in one of the courses of the Mediterranean Centres of the UGR in Guadix, "WHO's projection is terrifying, as they have suggested that, in 15 years, the amount of diabetes 2 will double in the world and the incidence of different types of cancer will probably increase".

But the key is to know that, modifying these three life habits, "we can prevent up to 80% of the cardiovascular diseases and 40% of the different types of cancer. The importance of this research lies in it".

	The Vegan Diet As Chronic Disease Prevention: Evidence Supporting the New Four Food Groups by Kerrie K. Saunders (Author) The United States is one of the sickest nations on the planet. Despite our wealth, access to educational media, natural resources, and opportunity, most Americans accept atherosclerosis, cancer, hypertension, osteoporosis, heart disease, stroke, diabetes, and other degenerative chronic diseases as part of the normal aging process. Unfortunately, even our traditional "modern medicine" practitioners believe this misguided and bleak picture out of ignorance. This is because in a traditional curriculum, many physicians-in-training only receive one course in nutrition—the safest, most effective, and least expensive form of chronic disease prevention available. This one course is guided by the faulty 1992 "Food Pyramid" of the American Dietetic Association (ADA), which derived from the even...
	Take Charge of Your Diabetes This book is dedicated to all people living with diabetes, in honor of your struggles and your strength. Many of us strive for a sense of balance in our lives. We want to keep our goals in harmony with our minds and souls. People with diabetes often have stories to share about their struggles for balance and harmony in their lives. We can honor people by listening to and learning from their stories to find meaning and hope for our own lives. An old, well-loved story, told around the world, is about the turtle and a sure-footed animal, like a rabbit. In this story, the turtle tricks the other animal to win a race—simply by not giving up and by staying on its path. And it has to stick its neck out! It takes determination like that to face diabetes, day after day,...

	Inflammation, Lifestyle and Chronic Diseases: The Silent Link (Oxidative Stress and Disease) by Bharat B. Aggarwal (Editor), Sunil Krishnan (Editor), Sushovan Guha (Editor) Oxidative stress and inflammation are among the most important factors of disease. Chronic infections, obesity, alcohol and tobacco usage, radiation, environmental pollutants, and high-calorie diets have been recognized as major risk factors for a variety of chronic diseases from cancer to metabolic diseases. All these risk factors are linked to chronic diseases through inflammation. While short-term, acute inflammation generated by the immune system serves a therapeutic role, chronic low-level inflammation that may persist "silently" for decades is responsible for chronic diseases. Inflammation, Lifestyle, and Chronic Diseases: The Silent Link describes the role of dysregulated inflammation in persistent and recurring diseases. It investigates links to lifestyle and presents research...
	Sick Societies: Responding to the global challenge of chronic disease by David Stuckler (Author), Karen Siegel (Author) Chronic diseases are the leading causes of death and disability worldwide. Within the next few decades, the burden of chronic disease will more than triple, with the greatest rises occurring in developing countries. However, the rapid growth of chronic diseases is not being met with a proportionate increase in global attention, with global health traditionally focusing on infectious disease and maternal and child health. This book is the first to synthesise the growing evidence-base surrounding the chronic disease, comprehensively addressing the prevention and control of chronic diseases from epidemiologic, economic, prevention/management, and governance perspectives. Sick Societies is written in five main parts; the first part of the book aims to understand the causes and...
