Why vegetarian diet checker matters
A vegetarian diet excludes meat and fish but may include dairy products and eggs. It focuses on plant foods with optional animal-derived products like milk, cheese, and eggs.
- 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
- Don't rely too heavily on cheese as a protein source
- B12 is still important if limiting animal products

What to know about cola
Cola stacks up three things that bother sensitive people at once: caffeine (about 34 mg in a 12 oz can), phosphoric acid that gives it a tooth-eroding pH near 2.5, and a large dose of sugar or high-fructose corn syrup. That combination is why cola is a classic driver of reflux and of the caffeine-withdrawal "cola headache," and the sugar load makes it pro-inflammatory and poor for SIBO. It is clean on histamine, gluten and lactose, so the issue is the caffeine-plus-acid-plus-sugar package, not a food-chemistry trigger.
Watch for
- Moderate caffeine, enough to feed a dependence and to cause a rebound headache when you skip your usual can, which is the real "cola headache"
- Phosphoric acid gives cola a very low pH (around 2.5), a common reflux and heartburn trigger and hard on tooth enamel, made worse by the carbonation
- High in sugar or high-fructose corn syrup, so it rates pro-inflammatory, poor for SIBO, and carries moderate excess-fructose and polyol loads from the sweeteners
- Diet colas drop the sugar but keep the caffeine and phosphoric acid, so they still hit the reflux and headache angles
