Through research I have learned milk isn’t good for your body. Now i have never been one to drink milk, but i do still eat ice cream, cheese and sour cream. I just find it to hard to give up but maybe one day I will for good.
- Milk isn’t constructed for us, its made for calf’s. The biological purpose of cow’s milk is to feed a rapidly growing calf. Humans aren’t calves… and adults usually don’t need to grow. Milk is not a natural substance for us. Before the agricultural revolution, humans only drank mother’s milk as infants. They didn’t consume dairy as adults. Did you ever wonder why dairy wasn’t included in the strict paleo diet?
The enzyme lactase that is located in the villus enterocytes of the small intestine is responsible for digestion of lactose in milk. Lactase activity is high and vital during infancy, but in most mammals, including most humans, lactase activity declines after the weaning phase. In other healthy humans, lactase activity persists at a high level throughout adult life, enabling them to digest lactose as adults. This dominantly inherited genetic trait is known as lactase persistence.
A study was conducted:
Improved Lactose Digestion and Intolerance Among African-American Adolescent Girls Fed a Dairy Rich-Diet
Objective To determine whether African-American adolescent girls who were fed a dairy-rich diet for 21 days could adapt to lactose, experiencing an overall improvement in lactose tolerance as well as a decrease in hydrogen gas production.
Design Twenty-one–day dietary intervention study.
Subjects/setting Seventeen of 21 African-American girls (aged 11 to 15 years) enrolled in a calcium metabolism study chose to participate in the lactose tolerance study. Subjects were screened for any diseases, conditions, or medications that might alter calcium metabolism or colonic fermentation. Subjects were housed in a fraternity on the Purdue University, West Lafayette, Ind, campus, and were supervised 24 hours a day.
Intervention Subjects consumed a dairy-based diet averaging 1,200 mg calcium and 33 g lactose per day for 21 days. Lactose digestion was assessed by an 8-hour breath hydrogen test on days 1 and 21, and symptoms of intolerance (abdominal pain, bloating, flatulence, and diarrhea) were evaluated hourly on a ranked scale during the breath hydrogen tests and once each evening during the 21-day feeding period.
Main outcome measures A comparison of breath hydrogen production and gastrointestinal symptoms at the beginning and end of the study.
Statistical analyses performed The Wilcoxon signed ranks test was used to compare the area under the curve for the 2 breath hydrogen tests. Spearman’s p test for trend was used to determine whether there was a change in symptoms. All statistical analyses were 2-tailed and significance was set at P=.05.
ResultsFourteen of the 17 subjects had lactose maldigestion. Breath hydrogen excretion decreased significantly (P<.03) from the beginning (148.3±27.0 ppm×hours) to the end (100.7±19.3 ppm×hours) of the 21-day period. Gastrointestinal symptoms were negligible during both the breath hydrogen tests as were symptoms during the 21-day period.
Applications/conclusions The diet was well tolerated by the subjects. Furthermore, the decrease in breath hydrogen suggests colonic adaptation to the high-lactose diet. The results indicate that lactose maldigestion should not be a restricting factor in developing adequate calcium diets for this population. The existence of lactose maldigestion does not result in lactose intolerance in this population when it is fed a dairy-rich diet. J Am Diet Assoc. 2000;100:524-528.
Would you be surprised to know an astonishing three-quarters of us actually lack the enzyme to properly digest cow’s milk, and suffer digestively from the stuff. Most people begin to produce less lactase, the enzyme that helps with the digestion of milk, when they stop breastfeeding, around two years old. If our families don’t come from someplace that has raised dairy cows for centuries, it’s just not in our genetics to be able to process it. An estimated 98 percent of Southeast Asians, 90 percent of Asian-Americans, 74 percent of Native-Americans, 70 percent of African-Americans, and the majority of Jewish, Latino, and Indian people all suffer from lactose intolerance.
2. Milk is bad for your bones! Many scientific studies have shown an wide assortment of detrimental health effects directly linked to the consumption of milk. And the most surprising link is that not only do we barely absorb the calcium in cow’s milk (especially if pasteurized), but to make matters worse, it actually increases calcium loss from the bones. Crazy Right! “Consumption of dairy products, particularly at age 20 years, was associated with an increased risk of hip fracture in old age. (“Case-Control Study of Risk Factors for Hip Fractures in the Elderly”. American Journal of Epidemiology. Vol. 139, No. 5, 1994).”
And according to the United States Department of Agriculture, countries in the European Union and the United States are the number one and two milk consumers in the entire world. Yes, it’s true. Europeans and Americans not only consume the most milk, we also suffer the most cases of osteoporosis across the globe.
3. Increase risk of Cancer: Exposure to estrogen in milk increases the risk of cancer.
A Harvard study of women age 26 to 46 showed that those with the highest intake of dairy also had the highest risk of breast cancer.
For men, multiple studies have showed a strong link between milk consumption and prostate cancer. High IGF-1 levels are linked to increased risk of prostate cancer and breast cancer. Calcium may also play a role in prostate cancer. … For ovarian cancer, galactose, a component of the milk sugar lactose, has been under study as a possible culprit.
4.ACNE: Milk and dairy products contain growth hormones and inflammatory substances that clog your pores and cause acne. If you eat milk, cheese, ice cream, or any other kind of dairy, and you have acne, this blog post could be the most important thing you read all week.
