Factors Influencing Food Choices Figure 1.1 Copyright © 2011 Pearson Education, Inc. Many Factors Influence Our Choice of Foods Taste and Culture According to research, taste is the most important consideration in making food choices. Culture and tradition also determine food choices. A culture’s cuisine is greatly influenced by environmental factors, including: Climate and soil conditions Native plants and animals Distance from rivers, lakes, or the sea Accessibility Copyright © 2011 Pearson Education, Inc. Many Factors Influence Our Choice of Foods Social Reasons and Trends Eating is an important way to bond with others. Celebrations such as Thanksgiving are centered around food. Research shows that people consume 40 percent more when eating meals with others. Social activities can also involve eating certain foods. Popular trends influence the availability and variety of certain items, which ultimately affects your food choices. Copyright © 2011 Pearson Education, Inc. Many Factors Influence Our Choice of Foods Advertising Manufacturers spend over $10 billion annually on food advertising. Children and adolescents have a strong influence on household purchases. Food advertisers direct commercials toward children. Over half of television ads during Saturday morning cartoons are for food. A majority of food advertising is for sweets and treats such as candy, soft drinks, chips, and sugary breakfast cereals. Copyright © 2011 Pearson Education, Inc. Many Factors Influence Our Choice of Foods Cost, Time, and Convenience Eleven percent of American households experience food insecurity and may be forced to base food choices on cost. Americans want to spend less time preparing meals, which has influenced the types of foods sold in supermarkets. Today, Americans spend 45 percent of their food budget on the convenience of eating out, compared with just 25 percent in the 1970s. Copyright © 2011 Pearson Education, Inc. Many Factors Influence Our Choice of Foods Habits and Emotions Influence Not Only What You Eat, But When You Eat Your daily routine and habits can dictate what and when you eat. Many people use food as an emotional crutch during times of stress, sadness, or disappointment. Celebrations and happiness also trigger eating. Copyright © 2011 Pearson Education, Inc. Your Food Choices Differ From Those of Past Generations Nutrition Science Has Begun to Significantly Influence Our Food Choices Translating Nutrition Knowledge into Action One Bite at a Time Copyright © 2011 Pearson Education, Inc. Nutrition Science Has Begun to Significantly Influence Our Food Choices Past generations were concerned with health problems resulting from nutrient deficiencies. Rickets: linked to vitamin D deficiency Beriberi: caused by thiamin deficiency Laws were passed requiring enrichment of grains and other products with vitamins and minerals to prevent deficiencies. The RDAs (Recommended Dietary Allowances) were developed as nutritional guidelines to help Americans stay healthy. Copyright © 2011 Pearson Education, Inc. Nutrition Science Has Begun to Significantly Influence Our Food Choices Americans today are struggling with conditions such as overweight, heart disease, high blood pressure, and osteoporosis. Research suggests that many of these diseases can be prevented with a healthful diet. Laws and policies continue to evolve to reflect the latest nutrition research. Copyright © 2011 Pearson Education, Inc. Translating Nutrition Knowledge into Action One Bite at a Time The goal of this course is to empower you with knowledge that will affect your reasoning, judgment, and decision making about the foods you choose to eat. A lot of little adjustments in your diet can have a major impact on health. Each concept will give you practical strategies and tips to enable you to eat your way to better health. Copyright © 2011 Pearson Education, Inc. The Top Five Points to Remember 1. There are six categories of nutrients: carbohydrates, lipids (fats), proteins, vitamins, minerals, and water. 2.
