Study Notes

Nutrition is a critical aspect of human health, encompassing the nutrients we consume from various food sources and how those nutrients affect our wellbeing. It's what fuels us throughout the day and keeps our bodies functioning properly. Good nutrition involves consuming a variety of foods with adequate amounts of vitamins, minerals, proteins, carbohydrates, fats, fiber, and water. Eating a balanced diet can help prevent chronic diseases such as heart disease, stroke, type 2 diabetes, obesity, high blood pressure, osteoporosis, and some forms of cancer.

Macronutrients

Macronutrients are the three main types of nutrient categories that make up most of our daily calorie intake: protein, fat, and carbohydrate. Protein helps build muscle, repair tissue, and produce hormones; it's also key for recovery after exercise and injury. Sources of protein include lean meats, chicken, turkey, fish, eggs, dairy products like milk, cheese, yogurt, soybeans, lentils, nuts, seeds, beans, peas, whole grains, vegetables, fruits and plant-based meals. Fats play several important roles, including protecting organs, providing cushioning around joints, helping absorb certain vitamins, giving structure to cells, regulating body temperature, and serving as a source of energy when other nutrients aren’t available, while carbohydrates give your body its primary source of fuel, helping you maintain short bursts of energy during workouts or physical activities. Foods containing carbohydrates include fruits, vegetables, potatoes, legumes, pasta, rice, bread, cereal, and granola bars.

Micronutrients

Micronutrients are essential elements needed by the body in small quantities for normal growth and development. Examples of micronutrients include Vitamin A (for healthy eyes), calcium (strengthens bones and teeth) Iron (needed for making red blood cells to carry oxygen through the body), iodine (supports thyroid function), folic acid (important for pregnant women and growing babies), zinc (helps immune system function), potassium (maintains fluid balance and regulates blood pressure), magnesium (promotes bone health and nerve function), selenium (protects against cell damage), vitamin C (boosts immunity), and vitamin D (which allows one's body to absorb calcium). Most people get enough of these nutrients from their regular diets, unless there is an underlying medical condition.

Balanced Diet

A balanced diet consists of eating a wide variety of foods across all five major food groups - fruits, vegetables, grains, protein foods, and dairy - every day. This ensures that you're getting the full range of nutrients your body needs to stay healthy and strong, supporting good overall health and reducing risks associated with poor nutrition. To create a balanced meal plan, aim for at least half of each plate consisting of colorful non-starchy fruits and vegetables, a quarter of which made up of lean proteins, and another quarter filled with complex carbs and whole grains. By doing this consistently, you'll likely already have met many of your daily nutritional requirements without having to think too much about individual servings of specific nutrients.

In summary, proper nutrition ensures that your body has everything it needs to stay healthy. By focusing on macronutrients like protein, fat, and carbohydrates, and micronutrients like vitamins and minerals, you can keep your body running smoothly and reduce your risk of developing serious health problems down the line. Remember to enjoy a variety of foods within each category and strive for moderation - eating an excessively large amount of any single nutrient can lead to issues over time.
