"Breast is bestthat's why I nursed my own sons and I encourage other moms to continue this natural practice, which has been essential to human health since the dawn of time," Anderson writes in the letter.
"There is nothing natural about giving human babies milk that is meant for baby cows, who have four stomachs and gain hundreds of pounds in a matter of months," she adds.
The "Baywatch" star said cow's milk has often caused allergies to babies and children, and has also been linked to many diseases.
"Buying dairy-based formula also supports horrific cruelty to animals. As my friends at PETA have documented, cows on dairy farms are forcibly impregnated over and over again, and their calves are torn away from them when they are only a day old so that humans can siphon and sell their milk," Anderson writes.
"Heartbroken mother cows cry out in mourning for days over their missing calves," she adds.
