Craving ice or constantly reaching for salty foods may point to an underlying health issue or a deficiency in certain vitamins and minerals, experts warn. This is why it’s important to stay mindful of new habits, especially when they appear suddenly and without clear reason.

1. Alopecia

Gluten intolerance — particularly in conditions such as celiac disease — may lead to hair loss, including thinning of the eyelashes. This occurs because gluten can harm the small intestine, reducing the body’s ability to absorb key nutrients like zinc, iron, and biotin, which are vital for maintaining strong, healthy hair.
2. Swelling

Dairy allergies can trigger reactions not only in the digestive system but also in other parts of the body, such as the skin and lungs. Common symptoms may include:
- Rash
- Hives
- Swelling, particularly around the lips and face
- Wheezing
- Throat tightness
- Difficulty swallowing
In infants, dairy allergies can sometimes also cause blood in the stool.
More serious symptoms—such as throat swelling and trouble breathing—may signal anaphylaxis, a severe and potentially life-threatening allergic reaction. Anaphylaxis usually begins within minutes of consuming the allergen, though in some cases it may be delayed by several hours. Immediate action is crucial: administer epinephrine if available and seek emergency medical help right away. If epinephrine is not on hand, go directly to the nearest emergency room without delay.
