Beyond Macros: The Power of Micronutrients

In nutrition, much attention is often placed on macronutrients like carbohydrates, proteins, and fats. While macronutrients are undeniably important to our diets, they only scratch the surface of the nutrition our bodies need to function optimally. Enter micronutrients, the unsung heroes of our diets.

Imagine that your body is a city, and in that city are citizens, each with a specific job to keep the city running smoothly. In this case, the citizens are the micronutrients in your body. From boosting your immune system to improving your mood, micronutrients can have a significant impact on our daily lives. This week's newsletter is all about Micronutrients; the importance, their benefits, foods that are rich sources, and how they work together to keep our bodies running like well-oiled machines.

The Importance of Micronutrients:

Unlike macronutrients, MICRO-nutrients are needed in smaller amounts but are no less important to your nutrition. They are involved in practically every bodily function, from energy metabolism to bone health, and from cognitive function to cardiovascular health. I think you get the point. Deficiencies in micronutrients can lead to a range of health issues, such as increased susceptibility to infection, increased cognitive decline, and so much more.

One of the primary roles of micronutrients is their involvement in the body's antioxidant defense system. Antioxidants, such as vitamins A, C, and E, along with minerals like selenium and zinc, help neutralize harmful free radicals in the body, reducing oxidative stress and lowering the risk of chronic diseases such as heart disease, cancer, and neurodegenerative disorders.

Addtionally, one of the most significant aspects of micronutrients is their role in maintaining the body's metabolic processes. For example, Vitamin B12 is involved in the metabolism of fatty acids and amino acids. It serves as a cofactor for enzymes involved in converting these nutrients into usable energy. Similarly, iron is necessary for oxygen transport throughout the body, while zinc plays a vital role in immune function and wound healing.

Categories of Micronutrients:

Micronutrients are broken down into categories primarily for the purpose of understanding their functions, dietary sources, recommended intake levels, and potential health implications associated with deficiencies or excess intake. They are also structured into several categories based on their chemical composition and biological functions:

• Water-soluble vitamins: These vitamins dissolve in water and are not stored in the body, so they need to be replenished regularly. Water-soluble vitamins aid in energy metabolism, nervous system function, and the formation of red blood cells.
• Fat-soluble vitamins: These vitamins are absorbed with dietary fats and can be stored in the body's fatty tissues and liver. Fat-soluble vitamins aid in vision, bone health, immune function, blood clotting, and antioxidant activity.
• Macrominerals: These are typically needed in larger amounts. They are essential for various physiological functions in the body and aid in bone health, fluid balance, muscle function, and nerve transmission.
• Trace minerals: These are required in very small amounts but still very necessary. Trace minerals play important roles in various biological processes. Trace minerals also aid in oxygen transport, immune function, thyroid hormone production, antioxidant activity, and bone health.

Micronutrients and their Functions:

Now that we understand the different categories of micronutrients, lets discuss different types of micronutrients, their functions, and some of the physiological processes they assist in:

1. Vitamins:

• Vitamin A: supports eye health, vision, immune function, cell growth, reproduction, and fetal development. It is involved in maintaining the integrity of the skin and mucous membranes, which act as barriers against infection.
• Vitamin B complex: consists of eight water-soluble vitamins: thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin, folic acid, and cobalamins (B12). These vitamins aid in maintaining overall health, including brain function, energy levels, cell metabolism, hormone regulation, red blood cell production and DNA synthesis.
• Vitamin C: supports growth, development, and tissue repair. It aids iron absorption, boosts the immune system, supports wound healing, and maintains cartilage, bones, and teeth. It's an antioxidant that protects cells from damage by free radicals.
• Vitamin D: is essential for bone and teeth health, immune function, brain health, and regulating inflammation. It promotes calcium absorption and helps maintain adequate calcium and phosphorus levels in the blood.
• Vitamin E: acts as an antioxidant, and is another vitamin important for vision, reproduction, blood, brain, and skin health. It also aids in protecting cells from free radicals
• Vitamin K: Necessary for blood clotting, bone health, and other bodily functions. K helps in the production of proteins necessary for blood clotting and the building of bones.

2. Minerals:

• Calcium: with 99% stored in bones and teeth, Calcium supports bone and teeth health, muscle function, nerve signaling, and hormone release. Calcium intake is vital for children's bone development and maintaining bone density in adults.
• Iron: supports with oxygen transport in the body. It's a major component of hemoglobin, a protein in red blood cells responsible for carrying oxygen from the lungs to the rest of the body. Iron deficiency can lead to anemia, causing symptoms like fatigue and weakness. If you're someone who bruises easy, chances are you have low iron.
• Magnesium: is active in over 300 biochemical reactions in the body. Supports brain function, bone health, muscular function, maintaining a normal heartbeat, and blood glucose control. Magnesium is also involved in hormone receptor binding, muscle contraction, neural activity, neurotransmitter release, vasomotor tone, and cardiac excitability.
• Potassium: is a vital mineral and electrolyte crucial for various bodily functions, including nerve signaling, muscle contractions, and fluid balance. It is the third most abundant mineral in the body, with 98% found in cells. High potassium intake can lower the risk of stroke and kidney stones and may help reduce blood pressure and water retention.
• Zinc: is involved in cell division, cell growth, wound healing, and immunity. Zinc supports the breakdown of carbohydrates, enhancing the action of insulin, and is necessary for the sense of smell and taste.
• Selenium: plays a important role in human health as a component of selenoproteins, which act as antioxidants and support thyroid function, DNA synthesis, and immune response.
• Copper: supports numerous bodily functions including energy production, iron metabolism, and the formation of connective tissues and blood vessels. It also plays a role in the development and maintenance of the nervous system.
• Manganese: supports energy production, bone development, and the formation of connective tissues. It also plays a vital role in the metabolism of carbohydrates, amino acids, and cholesterol.
• Chromium: assists with metabolizing carbohydrates, fats, and proteins. It enhances insulin action, helping the body utilize glucose more effectively. Adequate intake supports energy production and muscle function.
• Iodine: supports hyroid hormone production and normal growth and development. It helps regulate metabolism and energy production.
• Fluoride: promotes good dental health by preventing dental cavities and building strong teeth and bones.
