Oral Signals: If you notice red, chronically chapped corners of the mouth, and pain in the lips and tongue, you are likely suffering from angular cheilitis due to malnutrition. If left unattended, it can lead to canker sores and lymphadenitis. Angular cheilitis is mostly caused by a lack of iron, Vitamin B2 (Riboflavin), and Vitamin B6. Internally, a deficiency of these two vitamins can cause anemia and affect the body's growth and development. To supplement, eat more green leafy vegetables like spinach, regularly consume pork, beef, liver, and legumes, or take Vitamin B complex supplements.
Lip Signals:
Cracked, peeling lips, and blurred lip lines are signs of lip problems, indicating a deficiency in Vitamin B2 and Vitamin C. To supplement, eat more green vegetables, citrus fruits, tomatoes, melons, potatoes, or take Vitamin B complex supplements and Vitamin C tablets.
Tongue Signals:
If you find your tongue is overly smooth, the taste buds are raised and red, and the sides of the tip of the tongue are yellow or white, you are deficient in folic acid and iron. A deficiency of these substances will hinder the production of red blood cells in the bone marrow, leading to glossitis, anemia, gastrointestinal dysfunction, and poor growth and development. To supplement, eat more liver, spinach, dark bread, and take Vitamin B complex supplements containing folic acid.
