"...When researchers tested various ethnic groups for their ability to digest lactose, however, their findings proved otherwise. Approximately 70 percent of African Americans, 90 percent of Asian Americans, 53 percent of Mexican Americans, and 74 percent of Native Americans were lactose intolerant.1-4 Studies showed that a substantial reduction in lactase activity is also common among those whose ancestry is African, Asian, Native American, Arab, Jewish, Hispanic, Italian, or Greek.5..."

This whole "you're not lactose intolerant until a doctor says you are" mentality is why I have little remorse for dragging dairy into the fluoride debate. Studies have shown that co-ingestion of calcium and fluoride reduces fluoride absorbed. It should follow that co-ingestion of fluoride also reduces calcium absorbed, and thus any dairy product containing fluoride will result in less calcium absorbed. Since dairy producers want to act like dairy is the best way to get calcium, then they should be concerned about fluoride lowering the amount of calcium absorbed, or at the very least use it as a marketing gimmick against competitors.
