INTRODUCTION
Food companies are profit-making organizations, and it is their responsibility to make profit in a socially acceptable way. The global rise in the prevalence of obesity that has taken place in recent years has led to skepticism about the way in which food companies make profits. For example, marketing and advertising methods that encourage consumers to "pay less-eat more" (such as supersizing) have been cited as irresponsible because they may promote overconsumption. This paper addresses some of the ways that Nestl is making a long-term commitment to the health and well-being of consumers.
There are very few countries in the world that are untouched by the obesity epidemic. Even in countries where a relatively low proportion of the population is overweight, the prevalence is increasing. In Europe, just as in America, over half of the population is overweight or obese. Nestl, as the world's largest food company, can be part of the solution to this global epidemic. Not only does Nestl have global presence, with companies in over 100 countries and factories in 86 countries, but the company also has the world's largest private nutrition research capability.
NESTLE POSITION ON OBESITY, NUTRITION, AND HEALTH
Nestl's position on obesity, nutrition, and health underscores the company's commitment to doing business in a socially responsible way. There are eight points:
* Nestl considers that proper nutrition and adequate physical activity are integral to maintaining good health. Therefore, the company not only makes continual improvements to the nutritional profile of its products, but is also actively involved in sports promotion (such as cricket, swimming, and ski programs) and sponsorship (such as by PowerBar) in markets across the world.
* Nestl believes every food has a role to play in achieving a balanced diet. We also recognize that many consumers need help in understanding how this can be achieved. Therefore, the company's position also addresses communication on nutrition and education.
* Nestl continues to use its significant scientific knowledge not only to develop new products to help consumers manage their health, well-being, and body weight, but also to improve the nutritional profile of existing ones.
* Nestl has always kept abreast of new developments in the nutrition sciences through research collaboration and its Nutrition Advisory Committee. This committee of world experts in nutrition has been in existence for over 25 years.
* Nestl is committed to responsible communication about all of our products, especially those consumed by children. In 2003, for example, the company revised its corporate communication principles to better reflect this commitment. Nestl's corporate business principles can be consulted on the company's website at http:// www.nestle.com/All_About/Business_Principles/.
* Nestl is committed to clear and "user-friendly" nutrition labeling to help consumers make well-informed food choices. This is done both on and off packaging.
* Nestl will expand the encouragement of nutrition education programs for the public, and this is being done in markets around the world.
* Nestl will collaborate closely with public health bodies, both national and international, in efforts to reduce the incidence of global obesity. For example, the company has developed dialogue with the World Health Organization (WHO) on nutrition and health topics.
Global obesity presents a challenge for the food industry, because food is part of the solution. Nestl is tackling this in a number of ways, as outlined in the company's position above. Science- based product renovation and innovation are an important aspect of this overall strategy. Nestl has a broad product range, which includes main courses, milk, and water, chocolate and candies, and specialized nutrition products for infants, the elderly, and the infirm. This means that product improvements require a multidisciplinary portfolio of research and development.
Renovation may be secondary to company policies that specifically address consumer health across the product portfolio. For example, Nestl has a company policy with respect to fortification, trans- fatty acids and salt, and is currently developing a policy on sugars. Alternatively, product renovation may be specific to individual products.
CONSUMER BENEFITS
Product renovation, or innovation, starts with consumer insights, which tell us that, above all, our consumers want great-tasting foods-however, increasingly, consumers also want healthy foods. Taste and health are therefore key drivers for product purchase. Bringing taste and nutrition together in the same product is not easy. If products deliver nutrition but not taste they are unlikely to be bought very often, and a food not bought has no commercial benefit. And if it is not eaten, food will not confer any nutrition benefits either. Therefore, our challenge is to manufacture foods that taste great and provide good nutrition. At Nestl we are working on both taste and nutrition in order to make the tasty choice the healthy choice.
Food companies can renovate existing products relatively quickly, usually within 1 to 3 years. For health purposes, these renovations include low-fat, low-sugar, high-fiber foods. Nestl first had such renovated products on the market about 15 years ago.
Last year, we asked all of our markets to provide us with examples of products that they had renovated for health over the last 5 years. We were inundated with many hundreds of examples. These include enriched products (e.g., with vitamins or minerals), as well as products that are low in fat, low in sugar, and low in calories.
The consumer benefits of this kind of product renovation range from calorie control to being heart friendly to helping to control postprandial blood glucose to helping with blood pressure control. Of course, product improvements such as these, even though they are made by many food companies, will not provide the only solution to the global rise in obesity and noncommunicable diseases, but product renovations of this kind are part of a bigger lifestyle picture that includes healthy eating and exercise.
In contrast to renovation, product innovation requires a long- term commitment in research and development. It may take 5 or more years to innovate products. The innovation process includes evaluating the efficacy of new products in properly conducted scientific studies, which we can communicate appropriately to the consumer. This can be illustrated for heart health.
Soft, general claims such as "may keep your heart healthy" can be made for foods that are high in whole grain because of the scientific evidence linking a diet high in whole grains with heart health. Nestl makes such a claim for shredded wheat breakfast cereal in the United Kingdom. However, more specific claims such as "actively reduces cholesterol absorption" for foods containing plant sterols requires more specific scientific substantiation. In fact, the cholesterol-lowering effect of plant sterols has been shown in numerous appropriately designed clinical trials.
NESTLE RESEARCH AND DEVELOPMENT
Nestl's global research and development network comprises the Nestl Research Centre, which focuses on basic research, as well as nine product technology centers and seven research and development centers. Nestl has nutrition expertise in every research and development facility and in every market.
The Nestl Research Centre was inaugurated in 1987, and is Nestl's center for basic knowledge in the food and life sciences. This knowledge is applied to the whole Nestl group, while also being part of the international scientific community. Last year, we had 483 outside contracts, published 208 papers, and registered 17 patents.
The Nestl Research Centre focuses on nutrition, health, and well- being. There are departments that specialize in food science, food- consumer interactions (including sensory science and consumer behavior), nutrition, and health, and basic research in pet nutrition. These fundamental departments are supported by work in the departments of bioanalytical science, quality, and safety and the nutrition network (which encompasses nutrition expertise in Nestl's global research and development network). The combined work of all of these departments can be summarized as being either food- oriented before consumption (food structure, taste, flavor, aroma, and appetite) or consumer-oriented after consumption (nutrient bioavailability, biomarkers of health, and intra-individual differences).
An example of Nestl's long-term research is the use of beta- glucans (soluble fiber) for slowing down the absorption ofnutrients such as glucose. Delayed glucose absorption is associated with a reduction in peak blood glucose and a more sustained elevation of blood glucose. The consumer understands this as "long-lasting energy."
One way that Nestl translates scientific knowledge for consumers is using "branded active benefits." The benefits of beta glucans are highlighted on the package using a trademarked logo and the term "BG- 3." Nestl has also trademarked logos to identify its products specially formulated to provide other benefits such as vitality/ protection, cholesterol lowering, bone mineral density, energy release, immunity, intestinal health, and growth and development.
INNOVATION IN THE FUTURE
At Nestl, we are thinking beyond 5 years into the future of nutrition science. We are interested in tailored, or personalized, nutrition through a better understanding of metabolism. Metabolism is highly complex because it concerns the whole body and interactions between different organs. Further, metabolism is tightly regulated by hormonal and nervous factors, while being influenced by environmental factors and nutritional status. Nevertheless, conventionally, we try to evaluate this with a single biomarker or end point such as cholesterol. For example, if a consumer's blood cholesterol is high, then we expect that he/she will benefit from foods containing plant sterols, but in reality human health is more complicated than this. Individuals may be be susceptible to more than one noncommunicable disease, each one influenced by different nutritional factors.
Therefore, we are taking an integrative biological approach to understanding health in order to try and identify health benefits (such as weight control) in response to different foods or diets. In relation to weight control, one of our research goals is to understand body fat. We want to better understand the differences between subcutaneous fat and the fat that is specifically stored around the abdomen and viscera. We know that people with excess abdominal and/or visceral fat are at increased risk of type 2 diabetes, hypercholesterolemia, hypertension, and atherosclerosis, so this understanding is critical.
We have collected fat biopsies from women who attended the local teaching hospital for surgical treatment of their obesity. Using comparative gene arrays, we found that over 6000 genes are differently expressed in the two types of fat. Although we are primarily interested in the pattern of gene expression, rather than in individual genes, we have observed that many of the genes that are expressed preferentially in visceral fat seem to be associated with inflammation, and this may help to explain why fat from around the abdomen is associated with chronic metabolic diseases. We are now using metabolomics to study the metabolic profile in the urine, blood, and saliva of the same patients. In the longer term, it would be interesting to explore how nutrients, foods, or diets influence gene expression in adipose tissue at different sites.
CONCLUSION
Einstein once said, "Today's problems cannot be solved by thinking the way that we thought when we created them." We might apply this to today's problems with noncommunicable diseases, which cannot be reduced by continuing to live as we have been living for the past 40 years or so. We need to better address how lifestyle affects long-term health. Food companies have a role to play in improving people's health and wellness by improving the nutritional profile of foods, ensuring sound communication on nutrition and consumer education, and collaborating with other stakeholders in order to be part of the solution.
