3. A Swollen or Red Tongue
What This Might Mean
Your tongue can reveal a lot about your health. A red, swollen, or unusually smooth tongue may suggest:
- Vitamin B deficiencies (B2, B3, B6, or B12).
- Anemia, caused by low iron.
- Food sensitivities or allergies.
Ways to Help
- Add lean meats, dairy, and fortified grains for B vitamins.
- Boost iron intake with spinach, beans, and whole grains.
- Pay attention to foods that trigger irritation.
4. Weak or Brittle Nails
Why Nails Matter
Your nails are often a reflection of your inner health. Weak, brittle, or ridged nails may signal:
- Calcium deficiency, affecting nail and bone strength.
- Iron deficiency anemia, leading to pale or spoon-shaped nails.
- Thyroid imbalance, which slows nail growth.
