The New Nutrition Science Project Public Health Nutrition: 8(6A), 673–694 DOI: 10.1079/PHN2005819 The new nutrition science project Geoffrey Cannon1,* and Claus Leitzmann2,* 1World Health Policy Forum, Juiz de Fora, Minas Gerais, Brazil: 2Institute of Nutrition Science, Justus-Liebig University, Giessen, Germany Abstract Objective: To show that nutrition science, with its application to food and nutrition policy, now needs a new conceptual framework. This will incorporate nutrition in its current definition as principally a biological science, now including nutritional aspects of genomics. It will also create new governing and guiding principles; specify a new definition; and add social and environmental dimensions and domains. Method: A narrative review of nutrition science, its successes and achievements, and its dilemmas, paradoxes, shortcomings, dissonances and challenges. Reference is made to 16 associated papers. Equal use is made of continuous text and of boxed texts Keywords that extend the review and give salient examples.

The discovery of new worlds begins by becoming open to new ideas. As from the last decades of the twentieth century, the linked political, financial and electronic revolutions known as ‘globalisation’, together with bioscientific and biotechnological discoveries, and demographic, nutritional and epidemiological trends, all together make a new world that needs new maps. Nutrition therefore now needs a new conceptual framework, as a biological and also an environmental and social science, able to analyse and assess all relevant determinants of well-being and disease, and to take effective action. The new nutrition science will follow ethical and ecological principles, respect history, tradition and culture, affirm human rights, and be committed to the creation and maintenance of policies and programmes designed to preserve and protect the human, living and physical world all together. The New Nutrition Science project is work in progress to these ends. together.

    2012 December blog Geoffrey Cannon Havana, Cuba, and now just arrived back in Brazil. Writing now a week or so after the XVI SLAN conference, my hero is a man of whom I was only vaguely aware before I arrived at José Martí International Airport outside Havana. Yes, this is José Martí. José Martí Good nutrition and land reform For Cubans, José Martí is a definition of his country’s aspirations and identity. He is as much the national hero and martyr as is Che Guevara. His own attempt to liberate Cuba, in his day from Spanish rule, ended very soon after he and his companions came ashore in 1895. He was killed in his 43rd year, in the first battle. Fidel Castro, who came ashore a little over 60 years later, has always acknowledged José Martí as his inspiration. Very good, you may be thinking, but how does this relate to nutrition and to public health? José Marti, shown above and below, and other liberators, are relevant to our work. A reason is land reform, with the purpose of giving freedom for family and co- operative farmers to grow what’s natural in the land in which they live, to feed their communities and their families and to nourish their country. This was and remains the great issue in Cuba, whose economy since the Spaniards came saw and conquered half a millennium ago, has depended on sugar, tobacco and coffee. José Martí: from left, birthplace; campesino leader and teacher; soldier and man on horseback (in Central Park, New York City); and Cuban national hero The first three pictures show José Martí’s birthplace, and then him as a campesino and an educator committed to land reform.

    World Nutrition Volume 4, Number 1, January 2013 2013 January column Geoffrey Cannon My heroes for 2012: Visionaries of big pictures, lovers of good food, public health advocates, professors, naturalists, writers, activists, revolutionaries Writing just before the end of a hard year, and expecting harder times ahead, I’ve selected what I’ve said about my 2012 heroes, hoping that they can continue to enlighten us. Here they are, above. From left, the top row shows Lynn Margulis, Michael Pollan, George Orwell, Colin Tudge, Claudia Roden, Christopher Hitchens, and Inês Rugani, two of whom were heroes in the same month. The bottom row shows MFK Fisher (as a young and old woman), Patti Rundall, Caroline Walker, Barbara Burlingame, Rudolf Virchow, and José Martí. (You can access them all on google or wikipedia or through my 2012 columns, by using the links below). World Nutrition My heroes of 2012 Now seeing them all together I am wondering if there are any general themes or connections here. There are more or less equal numbers of women and men, of living and dead people, and of colleagues (and friends) with people I know only from reading or reputation. They are all Americans or Europeans (unless places of birth and upbringing are counted). An equal imbalance is that all were born in the last 200 years. Some are or were nutritionists. ‘Caroline Walker, nutritionist’, Caroline always said, after rising to intervene in conference exchanges; Inês Rugani is a professor of nutrition at the state university of Rio de Janeiro; and Barbara Burlingame, a senior official at the UN Food and Agriculture Organization, identifies herself as a nutrition scientist.

  • Vegetarianism and Human Health
    Vegetarianism and Human Health Usha R. Palaniswamy SUMMARY. Vegetarianism dates back to a time before recorded history and, as many anthropolo- gists believe, most early humans ate primarily plant foods, being more gatherers than hunters. Human diets may be adopted for a variety of reasons, including political, esthetic, moral, environmental and economic concerns, religious beliefs, and a desire to consume a more healthy diet. A major factor influencing the vegetarianism movement in the present time is primarily associated with better health. Epidemiologic data support the association between high intake of vegetables and fruit and low risk of chronic diseases and provide evidence to the profound and long-term health benefits of a primarily vegetarian diet. Vegetables and fruit are rich sources of nutrients, vitamins, minerals, and dietary fiber as well as biologically active nonnutrient compounds that have a complementary and often multiple mechanisms of actions, including antioxidant, anti-inflammatory, hypoglycemic, hypocholesterolemic, and hypolipidemic properties, and mechanisms that stimulate the human immune system. Because of the critical link established between diet and health, consumers have begun to view food as a means of self-care for health promotion and disease prevention. Functional foods are targeted to address specific health concerns, such as high cholesterol or high blood sugar levels, to obtain a desired health benefit. Functional properties identified in a number of plant species have led to a modern day renaissance for the vegetarian movement. t is often asserted that humans are naturally vegetarian because the human body resembles plant eaters, not carnivores. However, Ihumans are omnivores, capable of eating either meat or plant foods, or general feeders, with more generalized anatomical and physi- ological traits.

  • Vitamins and Minerals: a Brief Guide
    Vitamins and minerals: a brief guide A Sight and Life publication Vitamins and minerals: a brief guide Vitamins are organic nutrients that are essential for life. Our bodies need vitamins to function properly. We cannot produce most vitamins ourselves, at least not in sufficient quantities to meet our needs. Therefore, they have to be obtained through the food we eat. What are vitamins A mineral is an element that originates in the Earth and always retains its chemical identity. Minerals occur as inorganic crystalline salts. Once minerals enter the body, they remain there until and minerals? excreted. They cannot be changed into anything else. Minerals cannot be destroyed by heat, air, acid, or mixing. Compared to other nutrients such as protein, carbohydrates and fat, vitamins and minerals are present in food in tiny quantities. This is why vitamins and minerals are called micronutrients, because we consume them only in small amounts. Each of the vitamins and minerals known today has specific functions in the body, which makes them unique and irreplaceable. No single food contains the full range of vitamins and minerals, and inadequate nutrient intake results in deficiencies. A variety of foods is therefore vital to meet the body’s vitamin and mineral requirements. Of the known vitamins, four are fat-soluble. This means that fat or oil must be consumed for the vitamins to be absorbed by the body. These fat-soluble vitamins are A, D, E and K. The others are water-soluble: these are vitamin C and the B-complex, consisting of vitamins B1, B2, B6, B12, niacin, folic acid, biotin, pantothenic acid and choline.

The views from my window of the ocean, the Pão de Açucar, and the Catete Palace Gardens, are fabulous. It’s the final day before our Rio2012 congress starts. As a laconic old Anglo friend of mine sometimes said, things could be worse. Wish you were here! Well, some of you are in-flight as I write, and at the end of today this column, our website, and World Nutrition, will be on- line, thanks to Martin Evans working outside Aberdeen in the north of Scotland. This month I choose two heroes. Here they are above, with their props. These are the my beloved friend, food writer Claudia Roden (left) holding fruit, whose latest and nineteenth book is on The Food of Spain. And here (right) is the public intellectual Christopher Hitchens, propped with smokes, coffee and Black Label, whose memoirs Hitch 22 were completed when he knew he would soon die, which he did last December. More of them below. This column is concerned with the social (including cultural), economic and environmental dimensions of nutrition. It suggests that we might do well to think less of nutrition and more of nourishment, and in terms of what marks us out as human, which are the heart, mind and spirit. Spirit? Not surely whisky, you may be thinking. No no, ten times no, but well, read on. Let’s hope we all agree that nutrition and public health are certainly about food and drink as prepared, cooked and enjoyed, as Claudia Roden is reminding us above with characteristic gentle charm.

  • Gender, Environment, and the Rise of Nutritional Science
    THESIS “LEARNING WHAT TO EAT”: GENDER, ENVIRONMENT, AND THE RISE OF NUTRITIONAL SCIENCE IN TWENTIETH CENTURY AMERICA Submitted by Kayla Steele Department of History In partial fulfillment of the requirements For the Degree of Master of Arts Colorado State University Fort Collins, Colorado Summer 2012 Master’s Committee: Advisor: Mark Fiege Co-Advisor: Ruth Alexander Adrian Howkins Sue Doe ABSTRACT “LEARNING WHAT TO EAT”: GENDER, ENVIRONMENT, AND THE RISE OF NUTRITIONAL SCIENCE IN TWENTIETH CENTURY AMERICA This thesis examines the development of nutritional science from the 1910s to 1940s in the United States. Scientists, home economists, dieticians, nurses, advertisers, and magazine columnists in this period taught Americans to value food primarily for its nutritional components—primarily the quantity of calories, protein, vitamins, and minerals in every item of food—instead of other qualities such as taste or personal preference. I argue that most food experts believed nutritional science could help them modernize society by teaching Americans to choose the most economically efficient foods that could optimize the human body for perfect health and labor; this goal formed the ideology of nutrition, or nutritionism, which dominated education campaigns in the early twentieth century. Nutrition advocates believed that food preserved a vital connection between Americans and the natural world, and their simplified version of nutritional science could modernize the connection by making it more rational and efficient. However, advocates’ efforts also instilled a number of problematic tensions in the ways Americans came to view their food, as the relentless focus on invisible nutrients encouraged Americans to look for artificial sources of nutrients such as vitamin pills and stripped Americans of the ability to evaluate food themselves and forced them to rely on scientific expertise for guidance.
