Who Should Avoid Eating Black Sesame Seeds? Important Health Warnings You Need to Know
Black sesame seeds have long been praised as a nutrient-dense superfood. Rich in healthy fats, calcium, antioxidants, fiber, and plant-based protein, they are widely used to strengthen hair, improve digestion, nourish the skin, and support overall wellness.
However, not everyone should consume black sesame freely. In certain cases, black sesame can trigger health issues or worsen existing medical conditions. Understanding whether black sesame is suitable for you is essential for maintaining good health and preventing unwanted side effects.
Below are the groups of people who should limit or avoid eating black sesame seeds.

1. People With Chronic Diarrhea or Weak Digestion
Black sesame seeds contain high levels of natural oils and fiber. While healthy for most people, these properties can overstimulate the digestive system.
Why avoid it?
It can worsen loose stools
It may trigger abdominal pain or bloating
It can prolong existing diarrhea
It may irritate a sensitive digestive tract
People with irritable bowel syndrome (IBS), chronic diarrhea, intestinal inflammation, or naturally weak digestion should avoid black sesame until their condition stabilizes.
2. Individuals With Gastroesophageal Reflux Disease (GERD)
Because black sesame is rich in fat – even though it is healthy fat – it can cause the stomach to produce more acid.
Risks for people with GERD:
Increased acid reflux
Chest discomfort
Burning sensation in the throat
Difficulty sleeping after consumption
Those with acid reflux or gastritis should consume black sesame in very small amounts or avoid it completely when symptoms flare up.
3. People Who Are Overweight or Trying to Lose Weight
