Why vegetarian diet checker matters

- Eggs and dairy can help meet protein needs
- Include a variety of plant proteins for balanced nutrition
- Iron-rich foods pair well with vitamin C

Serving size, prep, and portion notes for corn
Corn is naturally gluten-free, so the common worry that it contains gluten is a myth, though corn products milled in wheat facilities can pick up gluten by cross-contact. The real triggers are different: corn is high in free glutamates, the same savory compound behind MSG reactions, and moderately high in salicylates. It is also high in lectins and sits on the pro-inflammatory side, which is why some people feel bloated or headachy after corn even though it passes as a safe grain.
Watch for
High in free glutamates, so it can provoke the same headaches or flushing that people blame on MSG / Moderately high in salicylates, a trigger if you react to aspirin or salicylate-rich foods / High in lectins, which can bother people who are sensitive to them / Naturally gluten-free, but processed corn products can be cross-contaminated with wheat, so check labels if you have celiac disease
