This guide covers some of the most common foods people suspect as triggers. Everyone’s body is different—your personal reactive foods may not match general lists—but these categories often come up during elimination diets and IgG testing.

Dairy is one of the most frequently reported foods in sensitivity discussions. People may experience bloating, congestion, or skin issues after consuming:

Soy shows up frequently in sensitivity conversations because it’s present in many foods, including:

- Packaged foods containing soy lecithin
5. Nuts
Many people report reactions to nuts or nut-based products due to their concentrated proteins.
6. Corn

7. Nightshade Vegetables
Some individuals report sensitivity to nightshades such as:
- Tomatoes
- Peppers
- Eggplant

Symptoms vary widely.
8. Sugar and Processed Foods
While not always IgG-related, many people notice more inflammation, bloating, or discomfort after eating highly processed foods or sweets.
Why Lists Alone Aren’t Enough
Trigger foods are highly individual. Some people react to foods not listed here, while others tolerate every category above. This is why a personalized test such as Pinnertest can be more useful than guessing.
How Personalized Testing Helps
Pinnertest’s IgG Food Sensitivity Test helps identify your own reactive foods so you and your provider can:
- Design a targeted elimination diet
- See whether symptoms improve
- Reduce unnecessary restriction
