The periodic table is important for understanding the foods we eat every day. Let’s look at some key elements and why they matter:

1. Essential Nutrients:

   • Carbon (C), Hydrogen (H), and Oxygen (O): These elements are found in carbohydrates, fats, and proteins. They help give us energy and are necessary for our bodies.
   • Nitrogen (N): This element is found in amino acids, which are important for making proteins our bodies need.

2. Minerals in Our Diet:

   • Calcium (Ca): This is crucial for strong bones and teeth. In fact, about 99% of our body's calcium is stored in our bones!
   • Iron (Fe): This element is important for making blood. Around 70% of the body’s iron is in a part of our blood called hemoglobin.

3. Trace Elements:

   • Zinc (Zn): This is important for a healthy immune system. Our bodies only need a small amount, about 2-3 grams.
   • Iodine (I): This is necessary for our thyroid, which helps control many body functions. We only need about 150 micrograms each day.

In short, the periodic table helps us learn about the basic ingredients in our nutrition. This knowledge plays a big role in keeping us healthy and feeling good!
