How safe are homogenized and pasteurized dairy products? One of the most debatable controversies in nutrition today is about the effect of milk on health. Check out the various articles and informational materials on the Weston A. Price Foundation’s Web site. According to the Weston A. Price Foundation’s Web site (with permission of Sally Fallon to reprint the following information from the Web site).
1. "Dr. J. C. Annand has written a series of articles in which he has advanced the theory that the increase in the incidence of heart disease was proximately related to the on set of pasteurization of milk. Different population groups were studied in various parts of the world. His theory is that the heat process of pasteurization alters the protein found in milk and as a result heated protein is responsible for the large increase in the incidence of heart trouble in citizens of western civilization, during the course of the past generation.”
2. “Dr. Kurt A. Oster has advanced the theory that homogenization of milk is proximately related to the atherosclerosis which is so prevalent in citizens in developed countries of the western world. The reduction in the size of the fat particles caused by homogenization permits them to be assimilated into the stomach lining in a manner that was not contemplated by nature. When these fat particles along with xanthine oxidase get into the bloodstream the human system sets up a defense mechanism which results in the scarring of arteries."
Take into consideration the fact that you have debates or issues related to many ongoing studies of how milk affects the human body. Before you can take notes on the issue of what type of milk or nondairy beverage is healthy for the human body, you need to look at the most current medical and scientific journal articles from primary and secondary sources.
Another issue to debate is how much antibiotics and growth hormones are put in milk sold to the public? How does organic milk differ? Does organic, raw, or otherwise differently treated or untreated milk effect human health in different ways? These are questions for debates on nutrition. To begin researching the field for your own reports, papers, projects, documentaries, or debates, look at the campaigns. What microbes are found in raw milk? How would they protect or infect you? 
Consider Both Sides of the Issue
Begin by reading about both sides of the issue to get a perspective on what the controversy or issue actually emphasizes. Remember that “A Campaign for Real Milk” is a project of The Weston A. Price Foundation, PMB 106-380, 4200 Wisconsin Ave, NW, Washington DC 20016. Also see this other link at the Weston A. Price Foundation.
Raw milk is compared at the site to Pasteurized milk in California. While you’re taking notes, remain unbiased and look at all sides and scientific studies to get a handle on what’s being researched and why. List the pros and the cons, the health effects, and the consumer requirements of a beverage product such as milk.
Then research whether health-related studies are being performed on ‘milk’ that doesn’t come from an animal, such as rice milk, oat milk, and almond or hazelnut milk. That’s not milk at all, but a non-dairy beverage used in place of milk. What’s the effect on the body, the sugar content, and other nutrients in each beverage? Who’s studying that particular drink? What’s new?
Every decade, new definitive guides are published on many aspects of numerous foods. Is there really a definitive guide in the face of changing research findings about almost all foods studied as regards to effects on human health?
The Homogenized Milk Controversy
Is homogenized cow or goat milk good or bad for the health of humans? What about Pasteurized milk? The nutrition controversy and issues regarding milk have been ongoing in the medical journal reported studies for decades. What do cardiologists and other medical and scientific researchers report regarding what happens when one drinks cow’s milk? 
What about nondairy beverages such as almond milk, rice milk, oat milk, hazelnut milk, and other smooth beverages that taste good on fruit or cereal that are not actually milk at all? What happens when they are unsweetened, plain (sweetener added, but no flavoring), or sweetened, and you take a reading of your blood sugar level shortly after drinking the beverage?
Check out the uTube video titled "Milk is Poison" about the growth hormone in milk and its relationship to breast cancer and consider your own decisions and views regrding drinking body fluids from animals produced by Hard Copy about what's really in milk, what is injected into cows. Do you believe milk is the perfect food? The video emphasizes how every sip of milk has 59 different bioactive hormones and how these hormones affect your family.
Casein is the number one protein in milk. If casein is glue and used as glue in industry, does this type of glue cause formation of mucous in those who drink milk? Make up your own mind. Would drinking the casein in milk stimulate your asthma? Think about it.
