Your body often shows subtle signs when your diet is lacking, and many people miss them. Here are key symptoms to watch for and what they might mean:

“Brittle nails and dull hair” may mean you’re low on biotin (B7), which supports healthy hair and nails. It’s found in egg yolks, nuts, organ meats, and whole grains.

Painful canker sores or split lip corners might signal a lack of B vitamins or iron. “They’re not just annoying — they can be a sign” your body is missing nutrients. Add eggs, lentils, and chicken liver to your meals.

“Your gums bleed every time you brush”? It may be vitamin C deficiency, not brushing too hard. Flaky scalp or dandruff? You might need more zinc or B vitamins — cheese, seafood, and beans can help.

Hair falling out may relate to low iron or B vitamins. If “you struggle to see clearly in dim light,” you could be low on vitamin A — found in carrots and pumpkin.

Tiny skin bumps may signal low vitamins A or C. Restless legs at night could mean iron deficiency. Boost your intake with leafy greens, chickpeas, or even a cast iron pan.

Your body speaks — listen with your diet.
