The Science of Nourishment

Understanding Macronutrients

Carbohydrates are the body's primary source of energy. They are broken down into glucose, which fuels the brain and muscles. Complex carbohydrates—found in whole grains, legumes, and vegetables—provide sustained energy and contain fiber important for digestive health.

Proteins are essential amino acids required for building and repairing tissues, including muscles, skin, and organs. They also play roles in enzyme production, hormone regulation, and immune function. Protein sources include both animal products (meat, fish, eggs, dairy) and plant-based options (legumes, nuts, seeds, whole grains).

Fats are necessary for absorbing fat-soluble vitamins (A, D, E, K), supporting brain health, and maintaining cell membrane integrity. Unsaturated fats (found in olive oil, nuts, avocados, fatty fish) are considered beneficial, while saturated and trans fats have different physiological roles and should be consumed in moderation.

Micronutrients and Their Roles

Micronutrients—vitamins and minerals—are required in smaller quantities but are critical for numerous physiological processes. Vitamin C supports immune function and collagen production. Iron is essential for oxygen transport in the blood. Calcium and magnesium are vital for bone health and muscle function. A diverse diet rich in whole foods typically provides adequate micronutrients.
