Objective   To determine the impact of new types of drinking water on health.

  Methods   Parents mice were fed with magnetized mineral water, activated water, purified water, mineral water, alkaline ionized water and natural water respectively for 3 months, and of offspring mice for 3 months.

  Results   To compare with natural water, activated water and magnetized mineral water could significantly increase the body weight of paternal mice(P < 0.05), while mineral water and alkaline ionized water could significantly decrease the body weight of offspring male mice(P < 0.05), magnetized mineral water could significantly decrease the body weight of offspring mice(P < 0.05).Pur ified water could significantly decrease the neonatal mice weight(P < 0.05).Activated water and magnetized mineral water could significantly increase the neonatal mice number(P < 0.05).All the 5 new types of water had no effect on mice pregnancy rate, gestation rate and birth livability.In off spring mice, SOD activity could be increased sig nificantly(P < 0.05)by treating with magnetized mineral water, activated water, purified water, mineral water, while alkaline ionized water could decrease the activity of SOD significantly(P < 0.05).

  Conclusion   Five new types of drinking water could affect the body weight of mice, buthad no effect on pregnancy rate, gestaton rate and birth livability of mice.Magnetized mineral water, activated water, purified water and mineral water could increase SOD activity.
