How Do Bacteria Divide?

• In today's video we're looking at the different biological molecules or nutrients that you need for a healthy balanced diet
• Biological molecules/nutrients covered


  • Carbohydrates
  • Lipids
  • Proteins
  • Vitamins
  • Mineral ions
  • Fiber
  • Water
• Foods normally have a mix of different nutrients in them, not just one
• Carbohydrates


  Found most in starchy foods like bread, pasta, and potatoes, as well as in fruits and vegetables; provide energy for chemical reactions and movement
• Lipids


  Fats and oils; provide energy, act as long-term energy stores, insulate and protect organs
• Proteins


  Found in nuts, seeds, meat, fish, and legumes; act as building blocks for growth and repair of tissue; can be used for energy in emergencies
• Vitamins


  Organic molecules made by living organisms; needed in small amounts for various bodily functions
• Vitamin A


  • Found in liver and leafy vegetables; needed for good vision, skin, and hair health
• Vitamin C


  • Found in fruits and vegetables, especially citrus; prevents scurvy
• Vitamin D


  • Can be made by the body using sunlight; also found in eggs and oily fish; helps absorb calcium
• Minerals


  Inorganic, simple molecules; needed in small amounts for various bodily functions
• Calcium


  • Found in dairy products and leafy vegetables; needed for strong bones
• Iron


  • Found in red meat, spinach, and beans; component of hemoglobin that transports oxygen
• Fiber


  Type of carbohydrate not absorbed by the body; helps food move through the intestines properly
• Water


  Needed for chemical reactions, makes up about 70% of the body; constantly lost through breathing, sweating, and urinating
