In a study of women who had already had breast cancer, researchers found that consuming one or more servings of high-fat dairy raised the mortality risk by 49 percent compared with those women who ate less than half a serving a day, according to a study from the Journal of the National Cancer Institute. And several studies show that dairy products may increase your risk of ovarian cancer, as well. One culprit driving these cancers is the estrogen in dairy.
Estrogen gets passed through the dairy to humans, which is why so many studies are emerging about the link between full-fat dairy and hormonal cancers. Despite the fact that athletes are seen posing in milk ads, or that chocolate milk has been touted as a recovery drink, dairy appears to hinder athletic performance in several ways, Bausch says. For starters, it causes excess mucous production, which makes it harder to breathe during workouts.
Once that breathing is affected, your fitness performance will suffer. Dairy can also constrict blood flow and make the crucial delivery of nutrients and oxygen to the cells less efficient. Animals raised for meat have short lives: Chickens and pigs are killed at just a few months old while cows are about three years old. Dairy cows, however, must endure being strapped to milking machines for five years their normal life span is 15 to 20 years , and their existence is almost too sad to fathom.
In fact, lactose intolerance in infancy is a rare disorder. However, many people become lactose intolerant as their body slows down its production of lactase. Some dairy products that are fermented, such as yogurt and certain hard cheeses, contain lower amounts of lactose than a glass of milk.
These types of fermented products may be suitable choices for some people who are sensitive to lactose. Other people find that almost any amount of dairy causes symptoms. People who cannot digest dairy may wish to consume lactose reduced dairy milk or fortified soy milk alternatives.
Other nondairy milk alternatives do not provide similar nutrition. Learn more about lactose intolerance here. The majority of reliable evidence suggests that dairy can be an important nutrient-rich choice for a healthful diet. However, it is up to each individual to decide whether or not to consume it.
People who do not or cannot consume dairy should obtain calcium from other sources, such as fortified nondairy soy milk, leafy green vegetables, and other calcium-rich foods. People may wish to speak with a health professional about their dietary needs based on their health history and lifestyle.

Some people who are vegan, lactose intolerant, or who do not consume dairy products for other reasons wonder…. Is dairy good or bad for your health?
Medically reviewed by Kathy W. Warwick, R. This means that dairy products, with their relatively high fat content, are on the "eat sparingly" list. But new research , presented Tuesday at the annual congress of the European Society of Cardiology, suggests that the current advice to limit dairy intake should be reconsidered, especially for those who consume yogurt and cheese as opposed to milk. Whole milk still appears to increase the risk of heart disease, although the study authors did not quantify how great the increase was.
But most other dairy products, especially cheese and yogurt, were found to protect against both total mortality — death from any cause — and mortality from cerebrovascular causes. The average age of the 24, adult study participants was During the follow-up period of over six years, 3, deaths were recorded, including from cancer, from cardiac causes and from cerebrovascular disease. If you guzzled milk as a kid but now notice bloating or GI distress within a few hours of drinking it, ask your doctor to test you for lactose intolerance.
But don't rush to give up Brie just yet: Most lactose-intolerant people can comfortably handle dairy in moderation, according to Taylor. Yogurt with live active cultures has bacteria that predigest lactose, and cheese manufacturers occasionally remove the lactose-laden whey for easier digestibility. Some people still have problems with tiny amounts of dairy, but they're rare.
True milk and dairy allergies, of course, are serious, causing symptoms from hives to vomiting to anaphylactic shock. Americans drink 58 percent less whole milk than we did in , thanks to our national fat phobia. Saturated fat became public enemy number one after scientists concluded it increased our risk for heart disease, not to mention diabetes, strokes and cancer.
The dairy industry dutifully loaded grocery stores with low-fat and fat-free milk, cheese, yogurt, and ice cream. Unfortunately, the low-fat-diet craze backfired.
Willett, whose research published in the British Medical Journal in shows that low-fat dieters did not reduce their risk for heart disease. Sasson, for her part, recommends small amounts of full-fat dairy in place of lots of low-fat dairy and high-sugar, low-nutrient foods, since fat will at least make you feel full. Studies have suggested that dairy consumption contributes to our country's high rates of breast, ovarian and prostate cancer.
Some experts are wary of the growth hormones used on factory farms to boost milk production; others suspect milk's natural sugars and saturated fat. But the science on how dairy affects your health is far from definitive. Katz says it's "murky at best. Nothing I've learned has persuaded me to quit, full stop. Willett has shown that eating yogurt may even correlate with a lower risk for type 2 diabetes.
