Many Women Have One of These Nutrient Deficiencies

4. Iodine

Iodine is essential for regulating metabolism, immune response, and body temperature. It also supports the development of the skeletal and central nervous systems in fetuses and infants. Plus, eating too little iodine is the most preventable cause of intellectual disability in children.

Iodine deficiency is higher among people whose food comes from soil that lacks this trace element, and in places where salt is not iodized. Insufficient iodine intake is associated with these symptoms:

• Goiter (swelling of the thyroid gland)
• Fatigue
• Thinning hair
• Often feeling cold
• Weight gain
