Sensitivity notes
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 tagatose
Tagatose is a rare sugar, a ketose isomer of galactose that occurs naturally in tiny amounts in dairy and some fruits and is manufactured from lactose for commercial use. It tastes close to sucrose, around ninety per cent as sweet with a very similar mouthfeel and no cooling effect, and it browns properly in baking, which sets it apart from most sugar replacements. The trade off is what happens after you swallow it: most of a tagatose dose is not absorbed in the small intestine and passes to the colon to be fermented, which is why it grades as a genuine fermentable load rather than an inert sweetener.
Watch for
- Graded moderate on FODMAPs and on SIBO fermentation, and unlike most sweetener grades that is mechanistic rather than precautionary.The unabsorbed fraction really is fermented in the colon, producing gas and, at higher doses, osmotic loosening.
- It is not the same as allulose, though the two are often shelved together as rare sugars.Allulose is absorbed in the small intestine and then excreted in urine largely unchanged, so it is much gentler on the gut. Tagatose is not absorbed and ferments. If you tolerate allulose, do not assume tagatose behaves the same way.
- It is manufactured from lactose, which is worth knowing for anyone avoiding dairy for allergy rather than for lactose.The finished product is a purified monosaccharide with no milk protein, but the origin is dairy.
- Dose escalates the effect sharply.Small amounts in a formulated product are usually unremarkable; using it spoon for spoon in place of sugar in a home recipe is a much larger load.
- It has a genuine prebiotic effect, which is a benefit or a problem depending entirely on whether you have SIBO.
