October 9 Lecture Hunger and Malnutrition in the U.S.: What are metrics?: Food Calorie is spelled with a capital “C”=1,0000 cal or 1 kcal. One calorie is the quantity of thermal energy required to raise one gram of water 1ºC at 15ºC. Joule is the unit of energy in the metric system: 1 kcal (or “Cal”)= 4,200 joules Differen/t food components have different “energy densities” 1 gram of fat=9 calories 1 gram of carbohydrate=4 calories 1 gram of protein=4 calories 1 gram of alcohol=7 calories Calories required per day to maintain weight and good physiological status depends on age, body weight, level Of activity and gender. 733 million people suffer from hunger and malnutrition. Vast majority live in developing countries. Children are most vulnerable-nearly half of deaths in children under age 5 due to malnutrition (3.1 Million deaths per year). Famine and wars cause about 10% of hunger deaths. Hunger: a physical distress by the lack of food. Hunger can be chronic (long term) or acute (short-term). Undernutrition: goes beyond calories to signify deficiencies in energy, protein, and/or essential vitamins and Minerals. Malnutrition: A broad terms that refers to deficiencies, excesses, or imbalances in a person's intake of energy and/or nutrients. It includes undernutrition and overnutrition. Food insecurity: When people don’t have consistent and adequate access to enough safe and nutritious food To maintain an active and healthy life, they are considered food secure. A country's GHI (global hunger index) score is tabulated by averaging the percentages of four indices of hunger. Malnutrition deaths in U.S. Not eating enough but also from poor eating habits that lead to nutritional deficiencies. The majority of deaths in California from malnutrition last year occured in residents 85 and older. Malnutrition appears in conjunction with other illnesses. Food security: assured access at all times to enough food for an active, healthy life. Food insecurity: the recurrent and involuntary lack of access to enough food to fully meet basic nutritional needs Due to lack of financial resources. 18 million American households were food insecure at some time during 2023.
Understand the Problem
The question involves several topics regarding hunger, malnutrition, food insecurity, agricultural practices, and sustainability. It asks for explanations and understanding of these concepts as they relate to the context provided, which seems to be lecture notes or study materials. The key concepts include various definitions related to hunger and malnutrition, food security, and the implications of agricultural practices on health and the environment.
Answer
The lecture covers Food Calorie definition, energy density of nutrients, and hunger and malnutrition issues.
The lecture touches on the meaning of a Food Calorie (1 Calorie = 1 kilocalorie), energy density of food components (fats, carbohydrates, proteins, and alcohol), and the prevalence and consequences of hunger and malnutrition in the U.S. and globally.
Answer for screen readers
The lecture touches on the meaning of a Food Calorie (1 Calorie = 1 kilocalorie), energy density of food components (fats, carbohydrates, proteins, and alcohol), and the prevalence and consequences of hunger and malnutrition in the U.S. and globally.
More Information
The lecture likely provides insights into how malnutrition not only affects developing countries but is also a significant concern in developed countries like the U.S., often linked with other illnesses. It underscores the importance of understanding energy requirement metrics and addresses food insecurity affecting millions.
