    • Potassium: Important for proper muscle contraction, nerve impulse transmission, and maintaining fluid balance.

    • Zinc: Critical for immune system function, wound healing, and DNA synthesis.

  • Sources: Good sources of minerals include dairy products, leafy green vegetables, meat, beans, nuts, and whole grains.

Electrolytes
  • Function: Electrolytes are minerals that carry an electric charge when dissolved in body fluids like blood. They are vital for:

    • Regulating Fluid Balance: Helping to maintain the correct amount of water inside and outside cells.

    • Nerve Signals: Facilitating the transmission of electrical impulses throughout the nervous system.

    • Muscle Function: Essential for muscle contraction and relaxation, including the beating of the heart.

  • Key Electrolytes: The primary electrolytes in the body include sodium, potassium, calcium, magnesium, and chloride.

  • Sources: Electrolytes can be found in a variety of foods and beverages, such as fruits (e.g., bananas, oranges), vegetables, dairy products, sports drinks, and common table salt.

Vitamins
  • Function: Vitamins are organic compounds indispensable for numerous physiological functions, including:

    • Immune System Support: Boosting the body's defenses against illness.

    • Vision: Maintaining healthy eyesight.

    • Skin Health: Contributing to healthy skin and tissue repair.

    • Energy Production: Acting as cofactors in metabolic pathways that convert food into energy.

    • And many other processes.

  • Types:

    • Fat-Soluble Vitamins: These vitamins (A, D, E, K) are absorbed with dietary fats and stored in the body's fatty tissues and liver. They require fat for proper absorption.

    • Water-Soluble Vitamins: These vitamins (B-complex vitamins and Vitamin C) are not stored in the body in large amounts and excess amounts are typically excreted in urine. They need to be consumed regularly.

  • Sources: Vitamins are abundant in fruits, vegetables, dairy products, meats, and fortified cereals. Sunlight exposure is also a significant natural source for Vitamin D synthesis in the skin.

Fiber
  • Function: Fiber is a type of carbohydrate that the body cannot digest. It is crucial for:

    • Aids Digestion: Adding bulk to stool and facilitating regular bowel movements.

    • Promotes Bowel Health: Helping to prevent constipation and other digestive issues.

    • Helps Control Blood Sugar Levels: Slowing down the absorption of sugar, which can help prevent spikes in blood glucose.

    • Helps Control Cholesterol Levels: Soluble fiber specifically can help reduce LDL (bad) cholesterol.

  • Types:

    • Soluble Fiber: Dissolves in water to form a gel-like substance, found in oats, beans, apples, and citrus fruits.

    • Insoluble Fiber: Does not dissolve in water; adds bulk to stool, found in whole wheat, nuts, and many vegetables.

  • Sources: Excellent sources of fiber include whole grains, fruits, vegetables, legumes, nuts, and seeds.

Water
  • Function: Water is the most abundant compound in the human body and is absolutely essential for all bodily functions. Its roles include:

    • Regulates Body Temperature: Through sweating and respiration.

    • Removes Waste Products: Via urine and feces.

    • Lubricates Joints: Forming a crucial component of synovial fluid.

    • Aids Digestion: As a medium for transport and solubility of nutrients.

    • Transports Nutrients: Carries nutrients and oxygen to cells.

  • Sources: While pure water is the best source, significant amounts of water are also obtained from other beverages, and from many fruits (e.g., watermelon) and vegetables (e.g., cucumbers).

How to Make a Proper Plate and Portion Control
  • Plate Composition: For a balanced meal, aim for the following proportions, often visualized on a standard dinner plate:

    • Half the plate with non-starchy vegetables and fruits: These provide essential vitamins, minerals, and fiber with fewer calories. Examples include leafy greens, broccoli, carrots, berries, and apples.

    • A quarter of the plate with lean protein: Sources like chicken breast, fish, tofu, beans, or lentils help build and repair tissues and provide satiety.

    • A quarter of the plate with whole grains or starchy vegetables: Opt for options such as brown rice, quinoa, whole-wheat pasta, sweet potatoes, or corn for sustained energy.
