In brief: An “alkaline diet” can be healthy when it means more vegetables, fruit, legumes and fewer highly processed foods. The claimed “de-acidification of blood” is physiologically misleading.
What can diet actually change?
| Area | Interpretation |
|---|---|
| Urine pH | Can change |
| Blood pH | Tightly regulated |
| Vegetable intake | Can be beneficial |
| “Detox” | Not established |
Reviews of alkaline diets do not support the idea that healthy people can freely shift blood pH through ordinary food choices.[1]
