BASIC OF Understaning nutrition

 
 
 

1. Macronutrients and Micronutrients

  • Macronutrients include three essential components: carbohydrates, proteins, and fats. These nutrients provide the vital energy that your body requires to function effectively and grow properly.
    -Carbohydrates: These nutrients give you the energy you need to power through your day. They can be found in a variety of foods such as whole grains, fruits, and vegetables, which are all excellent sources.
    -Proteins: These important nutrients help build and repair tissues throughout the body. You can find proteins in foods like meat, beans, nuts, and dairy products, all of which contribute to your overall health.
    -Fats: These macronutrients provide a concentrated source of energy and also play a significant role in helping your body absorb essential vitamins. Healthy fats can be found in foods such as avocados, nuts, and olive oil, adding nutritional value to your diet.

  • Micronutrients encompass essential vitamins and minerals, such as calcium, iron, and vitamin C. These vital components play a crucial role in various bodily processes, including bone growth, oxygen transport throughout the body, and supporting overall immune function.

 

 2. Complex Carbs vs. Table Sugar

  • Complex Carbs: Found in whole grains, vegetables, and legumes. These take longer to break down, providing a steady release of energy and keeping you full longer.

  • Table Sugar (Simple Carbs): Found in sweets, sodas, and many processed foods. They are broken down quickly, leading to a rapid spike in blood sugar followed by a crash.

Why It Matters: Complex carbs help maintain energy levels, muscle longevity, power and prevent mood swings, while simple sugars can lead to energy crashes and are linked to weight gain.  AGAIN, MODERATION INCLUDING MODERATION

 3. Processed Foods (NOT GOOD)

  • What Are Processed Foods? These are foods that have been altered from their natural state, often with added sugar, salt, and unhealthy fats. Examples include chips, candy, frozen meals, and sodas.

  • Why They’re Bad: Processed foods often lack nutrients, are high in calories, and can lead to health issues like obesity, diabetes, and heart disease.
