"Nutrition is the biochemical and physiological process by which an organism uses food to support its life."
The study of how food and lifestyle choices impact health, including nutrition education, diet planning, and disease prevention.
Macronutrients: This includes carbohydrates, proteins, and fats, which are the three main types of nutrients that the body needs in large amounts to function properly.
Micronutrients: These include vitamins and minerals that the body requires in smaller amounts to support various biological functions.
Digestive system: The digestive system comprises the organs and enzymes that work together to break down food into small molecules that can be absorbed by the body.
Metabolism: The process by which nutrients are converted into energy or stored as fat for future use.
Diet and Disease: The role of nutrition in preventing and managing chronic diseases, such as obesity, diabetes, and heart disease.
Nutrition and Immune System: The relationship between diet and the immune system, and the impact of nutrition on the body's ability to fight off illness and infection.
Food safety and hygiene: The proper handling, preparation, and storage of food to prevent contamination and illness.
Diet trends and fads: An overview of popular diets and nutritional trends, and their potential benefits and risks.
Nutritional requirements across the lifespan: The nutritional needs of individuals at different stages of life, from infancy to old age.
Label reading and food marketing: The ability to distinguish between healthy and unhealthy food choices by reading food labels and understanding marketing claims.
Cultural and ethnic influences on diet: The impact of cultural and ethnic background on nutritional habits and preferences.
Sustainability and food systems: The environmental impact and sustainability of food production, distribution, and consumption.
Mindful eating: A practice that encourages individuals to pay attention to their food choices, hunger cues, and emotional responses to eating.
Food poverty and insecurity: Access to healthy, affordable food and social inequalities related to food.
Fitness and exercise: The relationship between physical activity and nutrition, and the importance of incorporating physical activity into a healthy lifestyle.
Healthy food preparation and cooking techniques: Tips and techniques to prepare healthy meals, including cooking methods and ingredient substitutions.
Macro-nutrients: These are nutrients that are required by the body in large proportions, such as carbohydrates, proteins, and fats. They provide energy, support growth and repair, and maintain various body functions.
Micro-nutrients: These are nutrients that are needed in small quantities, such as vitamins and minerals. They help the body carry out various metabolic functions and maintain good health.
Probiotics: These are live microorganisms that provide health benefits when consumed in adequate amounts. They are found in some foods such as yogurt and kefir and are believed to improve digestion and boost immunity.
Fiber: It is a type of carbohydrate that is indigestible and provides bulk to the diet. It promotes healthy digestion, bowel movements and helps regulate blood sugar levels.
Antioxidants: They are compounds found in various foods such as fruits and vegetables that help protect the body against oxidative stress and certain chronic diseases.
Phytonutrients: These are naturally occurring compounds found in plant-based foods that have been associated with a reduction in the risk of various chronic diseases.
Organic Foods: Foods grown without the use of synthetic pesticides and fertilizers are considered organic. They are believed to be healthier than conventionally grown foods.
Plant-based diets: These diets emphasize the consumption of whole plant-based foods such as fruits, vegetables, grains, and legumes while limiting or excluding animal-based foods.
Veganism: It is a lifestyle choice that excludes all animal products from the diet, including meat, dairy, and eggs.
Intermittent Fasting: It is a dietary pattern that cycles between periods of fasting and eating. It has been associated with various health benefits such as weight loss and improved metabolic health.
"It provides organisms with nutrients, which can be metabolized to create energy and chemical structures."
"Failure to obtain sufficient nutrients causes malnutrition."
"Nutritional science is the study of nutrition, though it typically emphasizes human nutrition."
"Organisms obtain nutrients by consuming organic matter, consuming inorganic matter, absorbing light, or some combination of these."
"Some can produce nutrients internally by consuming basic elements."
"Some must consume other organisms to obtain pre-existing nutrients."
"All forms of life require carbon, energy, and water as well as various other molecules."
"Animals require complex nutrients such as carbohydrates, lipids, and proteins."
"Humans obtain complex nutrients by consuming other organisms."
"Humans have developed agriculture and cooking to replace foraging and advance human nutrition."
"Plants acquire nutrients through the soil and the atmosphere."
"Fungi absorb nutrients around them by breaking them down and absorbing them through the mycelium."
"The type of organism determines what nutrients it needs."
