To overcome iron deficiency, you can eat the following types of food:
- Red meat
- Canned Sardines
Iodine is an essential mineral to support thyroid function and growth hormone. Without it, the body is unable to regulate metabolic rates, such as body growth, brain development, and bone maintenance.

To overcome vitamin D deficiency, you can eat the following foods:

Vitamin B12 deficiency
Known as cobalamin, vitamin B12 is a type of vitamin that is easily soluble in water. Vitamin B12 has a very important role to support blood formation and support brain and nerve function.
Although very important, unfortunately the body cannot produce B12 on its own. So, we have to get it from food or supplements. Deficiency of vitamin B12 nutrition can be anticipated with injections of vitamin B12 or high-dose vitamin B12 supplements.
A common sign of vitamin B12 deficiency is the appearance of megaloblastic anemia. This disorder is a blood disorder that enlarges red blood cells. Other common symptoms are impaired brain function and increased levels of homocysteine that trigger heart disease.
The following foods can meet the intake of vitamin B12:
Calcium deficiency for health
Calcium is essential for the maintenance of bones and teeth. In addition, calcium acts as a signaling molecule throughout the body. Without sufficient calcium, it is impossible for the muscles, nerves, and heart to function optimally.
If there is a lack of calcium, the body will take calcium reserves from the bones. This is the cause of osteoporosis can occur. This disease is characterized by brittle bones and pain. Serious calcium deficiency can cause soft bone disease or rickets in children, as well as osteoporosis in the elderly.
One way to meet daily calcium intake is to consume milk or its derivative products. You can also eat dark green vegetables, such as spinach, broccoli, and pakcoy which are high in calcium.
