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 grapefruit
Grapefruit is more than a tart breakfast citrus. It is very high in oxalate, high in salicylates, and acts as a histamine liberator, an unusual triple for a fruit, and it is high FODMAP by volume with a moderate excess-fructose load. On top of that trigger profile, grapefruit is famous for interacting with dozens of prescription medications, an effect most everyday citrus like oranges and clementines does not share.
Watch for
- Very high in oxalate, the most oxalate-heavy fruit in this group, which matters if you form calcium-oxalate kidney stones
- Histamine liberator and high in salicylates, so it can set off flushing, itching, headaches or a runny nose in people sensitive to either
- High FODMAP by volume, with a moderate excess-fructose load, so large servings or grapefruit juice can bring on bloating and loose stools
- Contains furanocoumarins that block the CYP3A4 enzyme, so grapefruit can raise blood levels of many statins, blood-pressure and other drugs to unsafe levels; check with a pharmacist
