Nutrients and Nutrition
- Nutrients are essential substances that provide energy, promote growth, repair body tissues, and regulate various bodily functions.
- They are obtained through the consumption of food and beverages and are vital for maintaining overall health and well-being.
Macro Nutrients
- The three primary macro nutrients are carbohydrates, proteins, and fats.
- Carbohydrates serve as the body's primary source of energy, broken down into glucose, and are found in grains, fruits, vegetables, and legumes.
- Proteins are essential for building and repairing tissues, synthesizing enzymes, hormones, and other vital molecules, and are found in meat, poultry, fish, eggs, dairy products, legumes, nuts, and seeds.
- Fats are a concentrated source of energy, provide insulation, cushion organs, and aid in the absorption of fat-soluble vitamins, and healthy sources include avocados, nuts, seeds, olive oil, fatty fish, and plant-based oils.
Micro Nutrients
- Micro nutrients are essential nutrients that the body requires in smaller quantities but are crucial for maintaining health and preventing deficiency-related diseases.
- The two main categories of micro nutrients are vitamins and minerals.
- Vitamins are organic compounds that play vital roles in various physiological processes, including metabolism, immune function, and cell growth, and are classified into fat-soluble and water-soluble vitamins.
- Minerals are inorganic elements that are essential for the proper functioning of enzymes, hormones, and other biological processes, and are divided into macro minerals and trace minerals.
Importance of Balanced Nutrition
- A balanced diet that includes adequate amounts of macro and micro nutrients is essential for meeting the body's needs for energy, growth, and overall health.
- A diverse diet that includes a variety of nutrient-rich foods is necessary for ensuring optimal nutrition and well-being.
