4. Iron
Are you always tired? What about low appetite, pale skin, diarrhea and/or constipation and dizziness – do these symptoms sound familiar to you? If so, you may need to increase your vitamin B12 and iron intake. Fish, red meat, dairy and eggs are all high in B12 while iron can be found in beans, lentils and spinach.
5. Calcium
Calcium is essential when it comes to maintaining strong bones and teeth, but it also plays an important role in muscle and nerve function.
“Calcium plays a role [in helping] your muscles to contract and your heart to beat,” Ginn says. “If you don’t get enough, it may impact growth for children but also impact bone density in adults.”
Signs of a severe deficiency include muscle spasms and aches, tooth decay and memory loss. Dairy products, kale, black-eyed peas, almonds, and turnip greens are just a few calcium-rich foods.
