Food Tech Overview Flashcards
What are food additives?
Food additives are substances added to food to enhance flavor, appearance, or preservation. They include preservatives, colorants, flavorings, and emulsifiers.
What does GMO stand for, and what does it mean?
GMO stands for Genetically Modified Organism. It refers to plants or animals that have been genetically altered using biotechnology to improve their characteristics, such as resistance to pests or improved nutritional content.
What is nutrition?
Nutrition is the process of providing or obtaining the food necessary for health and growth. It involves the intake and utilization of nutrients, including carbohydrates, proteins, fats, vitamins, and minerals.
What are the key nutrients essential for human health?
The key nutrients essential for human health include carbohydrates, proteins, fats, vitamins, and minerals. Each plays a critical role in maintaining bodily functions, growth, and overall health.
What are macronutrients, and why are they important?
Macronutrients are nutrients required in large amounts for energy and growth. They include carbohydrates, proteins, and fats. Each macronutrient has a distinct role in maintaining health, such as providing energy (carbohydrates and fats) or building tissues (proteins).
What are micronutrients, and what is their significance?
Micronutrients are nutrients required in smaller amounts but are crucial for health. They include vitamins and minerals that support various physiological functions, such as immune function, bone health, and energy production.
What is the role of protein in the diet?
Protein is essential for building and repairing tissues, making enzymes and hormones, and supporting immune function. Sources include meat, dairy, legumes, and nuts.
What is the role of carbohydrates in the diet?
Carbohydrates provide a primary source of energy for the body. They are found in foods such as grains, fruits, and vegetables.
What is dietary fibre, and why is it important?
Dietary fiber is a type of carbohydrate that the body cannot digest. It is important for maintaining digestive health and can help prevent chronic diseases such as heart disease and diabetes.
Why is water essential for health?
Water is crucial for maintaining hydration, regulating body temperature, and facilitating various physiological processes, including digestion and nutrient absorption.
What are vitamins, and why are they important?
Vitamins are organic compounds required in small amounts for various bodily functions. They are essential for processes such as metabolism, immunity, and cell repair. Vitamins include A, B complex, C, D, E, and K.
What are minerals, and what roles do they play in the body?
Minerals are inorganic nutrients that are vital for health. They support processes such as bone formation (calcium), oxygen transport (iron), and fluid balance (sodium). Common minerals include calcium, iron, magnesium, potassium, and zinc.
What are essential nutrients, and why must they be obtained from the diet?
Essential nutrients are substances the body cannot synthesize or produce in sufficient quantities. They must be obtained through diet to maintain health. Essential nutrients include certain amino acids, fatty acids, vitamins, and minerals.
What are non-essential nutrients?
Non-essential nutrients are substances that the body can synthesize on its own or in sufficient quantities. While they are not required from the diet, they still play important roles in maintaining health. Examples include some amino acids and fatty acids.
What are phytochemicals, and what benefits do they offer?
Phytochemicals are bioactive compounds found in plants that may have health benefits, such as reducing inflammation and lowering the risk of chronic diseases. They are not essential nutrients but contribute to overall health. Examples include flavonoids and carotenoids.
