Why lactose food checker matters
Lactose is the natural sugar in milk and dairy products. People with lactose intolerance lack sufficient lactase enzyme to digest it, leading to bloating, gas, and digestive discomfort after consuming dairy.
- Try lactose-free dairy products - they're real dairy with lactase added
- Hard aged cheeses are naturally lower in lactose
- Lactase enzyme supplements can help when eating dairy
- Yogurt and kefir may be better tolerated due to probiotics
- Your tolerance level is personal - some can handle small amounts

What to know about potato
Potatoes look like a plain, low-drama vegetable, but they are a nightshade and are rated high in oxalate, which is why they show up on so many elimination and AIP diets. If potatoes leave you achy, foggy or flared, the usual suspects are their nightshade glycoalkaloids (solanine and chaconine), their oxalate load and their lectins, not the starch itself.
Watch for
- Nightshade vegetable, so it is one of the first foods cut on a nightshade-free or AIP protocol for joint pain and inflammation
- Rated high in oxalate, a concern if you form kidney stones or are tracking a low-oxalate diet
- Contains glycoalkaloids (solanine and chaconine) that concentrate in green skin and sprouts, so green or sprouting potatoes are worth discarding
- Rated high in lectins, another reason lectin-avoiders skip potatoes even when they are cooked
