Why vegan diet checker matters
A vegan diet excludes all animal products including meat, dairy, eggs, and honey. It focuses on plant-based foods like vegetables, fruits, grains, legumes, nuts, and seeds.
- Ensure adequate protein from varied plant sources
- Supplement B12 - it's essential and not available from plants
- Consider omega-3 from algae-based supplements
Serving size, prep, and portion notes for aspartame
Aspartame is clean right across the food-chemistry triggers: no histamine, no tyramine, no salicylate, no lactose, no gluten, no sulfites, and it is low FODMAP with no polyol content, so it does not behave like the sugar alcohols people confuse it with. It has one hard, non-negotiable caveat, and it is genetic rather than digestive: aspartame is built from aspartic acid and phenylalanine, so anyone with phenylketonuria must avoid it, which is why packs carry a "contains a source of phenylalanine" warning.
Watch for
Contains phenylalanine, so it is unsafe in phenylketonuria (PKU). This is the only absolute restriction on it and it is the reason for the label warning / Graded pro-inflammatory and not compatible with paleo or AIP, both diet-pattern notes rather than sensitivity triggers / Diet colas and energy drinks sweetened with aspartame usually also contain caffeine and phosphoric acid, so if a diet drink gives you headaches or reflux, log the whole drink before you pin it on the sweetener
