π Understanding Essential Nutrients
Essential nutrients are compounds that the body can't make on its own or in sufficient quantity. Therefore, they must be obtained through food. These nutrients are vital for growth, repair, and overall health. Let's explore how to match these nutrients to their primary food sources.
π A Brief History
The understanding of essential nutrients evolved over centuries. Early sailors discovered that citrus fruits prevented scurvy, unknowingly highlighting the importance of Vitamin C. In the early 20th century, scientists began isolating and identifying specific vitamins and minerals, leading to a greater understanding of their roles in human health.
