Who should not eat chia seeds? Dermatologist lists 5 kinds of people who should avoid them

They might be tiny, but chia seeds have earned a big reputation as a superfood — sprinkled on smoothie bowls, soaked in detox water, or mixed into pudding. But as dermatologist Dr Jushya Sarin points out, they’re not for everyone. In a new Instagram post, the Harvard-trained skin expert shared a quick yet crucial reminder: while chia seeds are packed with omega-3, fibre, and antioxidants, some people need to be extra cautious before adding them to their diet.

Dr Sarin began her post by explaining that chia seeds can cause digestive discomfort for certain individuals.

1. Gas or bloating issues
“If you have gas, bloating, or gut issues, be careful,” she advised. Since chia seeds swell up when mixed with water, they can lead to cramps or a gassy feeling, especially for people with sensitive stomachs. Her tip? Start with just half a teaspoon and monitor how your gut reacts before increasing the quantity.

2. Low blood pressure

The dermatologist also warned people with low blood pressure to tread carefully. Chia seeds are naturally rich in alpha-linolenic acid and potassium — nutrients known to lower blood pressure. While that sounds healthy, it could make some individuals feel dizzy or weak if their blood pressure is already on the lower side.

3. Blood thinners

Dr Sarin added that those who take blood thinners should also limit or avoid chia seeds. The omega-3 content in chia can sometimes interfere with medications that thin the blood, potentially increasing the risk of bleeding.



4. Allergies

She further highlighted that people with seed allergies — especially to sesame, mustard, or flax seeds — might experience cross-reactions when consuming chia seeds. Symptoms such as itching, redness, or even breathing difficulties can occur, so she urged people to be alert to these warning signs.


5. Kidney problems

Lastly, Dr Sarin cautioned individuals with kidney problems to stay mindful. Since chia seeds contain potassium and phosphorus, consuming them in large quantities may not be safe for those with impaired kidney function.

Despite these precautions, Dr Sarin assured her followers that chia seeds are generally safe for most people when consumed in moderation. For everyday use, one to two tablespoons of chia seeds soaked in water is perfectly fine, she said. Her closing advice? Stay hydrated throughout the day if you eat chia seeds — your gut will thank you for it.
