I recently taught Breastfeeding Nutrition and Intro to Baby's 1st Foods and some of the coolest parts about teaching it was that a NICU nurse and mom of three came! That says a lot and makes me excited knowing she will be sharing what she learned. A mom said she now realizes her son's symptoms are an allergy to milk AND she is willing to stop eating/drinking it. AND another mom realized she was trying to feed her son too soon.
More on the milk subject here:
Health Concerns about Dairy Products
Many Americans still consume substantial amounts of dairy products—and government policies still promote them—despite scientific evidence that questions their health benefits and indicates their potential health risks.
Milk’s main selling point is calcium, and milk-drinking is touted for building strong bones in children and preventing osteoporosis in older persons. However, clinical research shows that dairy products have little or no benefit for bones. A 2005 review published in Pediatrics showed that milk consumption does not improve bone integrity in children.1 Similarly, the Harvard Nurses’ Health Study,2 which followed more than 72,000 women for 18 years, showed no protective effect of increased milk consumption on fracture risk.
A study published in the Archives of Pediatrics & Adolescent Medicine, which followed adolescent girls’ diets, physical activity, and stress fractures for seven years, found that girls consuming the most dairy products and calcium had no added bone protection. In fact, among the most physically active girls, those who got the most calcium in their diets (mostly from dairy products) had more than double the risk of stress fractures.3 While calcium is important for bone health, studies show that increasing consumption beyond approximately 600 milligrams per day—amounts that are easily achieved without dairy products or calcium supplements—does not improve bone integrity.2
In studies of children and adults, exercise has been found to have a major effect on bone density.4-6
You can decrease your risk of osteoporosis by reducing sodium,7increasing intake of fruits and vegetables,7,8 exercising,5,9 and ensuring adequate calcium intake from plant foods such as kale, broccoli, and other leafy green vegetables and beans. You can also use calcium-fortified products such as breakfast cereals and beverages.
Fat Content and Cardiovascular Disease
Dairy products—including cheese, ice cream, milk, butter, and yogurt—contribute significant amounts of cholesterol and are the number one source of saturated fat in the diet.10 Diets high in fat and saturated fat can increase the risk of heart disease, among other serious health problems. In two studies, hypertension—a known risk factor for heart disease—was significantly decreased among patients who practiced strict avoidance of animal products.11,12 A low-fat vegetarian diet that eliminates dairy products, in combination with exercise, smoking cessation, and stress management, can not only prevent heart disease, but may also reverse it.13,14 Nonfat dairy products are available; however, they pose other health risks as noted below.
Prostate and breast cancers have been linked to consumption of dairy products, presumably related to increases in a compound called ...
Case-control studies in diverse populations have shown a strong and consistent association between serum IGF-I concentrations and prostate cancer risk.18 One study showed that men who had the highest levels of IGF-I had an almost two-fold increased risk of prostate cancer, compared with those who had the lowest levels.19 Other findings show that prostate cancer risk was elevated with increased consumption of low-fat milk, suggesting that too much dairy calcium could be a potential threat to prostate health.18
Dairy products account for approximately 65 percent of estrogens consumed. Estrogens (and their metabolites) are a risk factor for breast, ovarian, and prostate cancers due, in part, to their ability to influence cell proliferation.20 A study suggesting that milk consumption may contribute to breast cancer risk reported that 15 different estrogen metabolites were found in various milk products. (There were no appreciable amounts of estrogen metabolites found in soymilk.)20 Cutting fatty foods is priority No. 1 when you endeavor to lower your risk for breast cancer, and, as noted above, dairy products are the No. 1 source of saturated fat in the diet.
Ovarian cancer may also be related to the consumption of dairy products. The milk sugar lactose is broken down in the body into another sugar, galactose. Research suggests that the dairy sugar galactose might be toxic to ovarian cells.21 In a study conducted in Sweden, consumption of lactose and dairy products was positively linked to ovarian cancer.22Additionally, a study conducted in Denmark—where the incidence of ovarian cancer is one of the highest in the world—found that women who consumed more than two servings of milk per day had nearly two times the risk of developing ovarian cancer than women who drank less than half a serving per day.23
Lactose intolerance is common among many populations, affecting approximately 95 percent of Asian Americans, 80 to 100 percent of Native Americans, 60 to 80 percent of African Americans, 50 to 80 percent of Hispanics,24 and 15 percent of Caucasians.25 Symptoms, which include gastrointestinal distress, diarrhea, and flatulence, occur because these individuals do not have the enzyme lactase that digests the milk sugar lactose. For those who can digest lactose, its breakdown products are two simple sugars: glucose and galactose. Nursing children have active enzymes that break down galactose. As we age, many of us lose much of this capacity.26 Additionally, along with unwanted symptoms, milk-drinkers also put themselves at risk for development of other chronic diseases and ailments.
Individuals often drink milk in order to obtain vitamin D in their diet, unaware that they can receive vitamin D through other sources. The natural source of vitamin D is sunlight. Five to 15 minutes of sun exposure to the arms and legs or the hands, face, and arms can be enough to meet the body’s requirements for vitamin D, depending on the individual’s skin tone.27 Darker skin requires longer exposure to the sun in order to obtain adequate levels of vitamin D. Fortified cereals, grains, bread, orange juice, and plant milks are healthful foods that provide vitamin D. All common multiple vitamins also provide vitamin D.
Milk contains contaminants that range from pesticides to drugs. Milk naturally contains hormones and growth factors produced within a cow’s body. In addition, synthetic hormones such as recombinant bovine growth hormone (rBGH) are commonly used in dairy cows to increase the production of milk.28 Because treated cows are producing quantities of milk nature never intended, the end result can be mastitis, or inflammation of the mammary glands. Treatment of this condition requires the use of antibiotics, and antibiotic traces have occasionally been found in samples of milk and other dairy products. Pesticides, polychlorinated biphenyls (PCBs), and dioxins are other examples of contaminants found in milk. These toxins do not readily leave the body and can eventually build to harmful levels that may affect the immune and reproductive systems. The central nervous system can also be affected. Moreover, PCBs and dioxins have also been linked to cancer.29
Milk Proteins and Diabetes
Insulin-dependent (type 1 or childhood-onset) diabetes is linked to consumption of dairy products.30 A 2001 Finnish study of 3,000 infants with genetically increased risk for developing diabetes showed that early introduction of cow’s milk increased susceptibility to type 1 diabetes.31
Health Concerns of Infants and Children
Milk proteins, milk sugar, fat, and saturated fat in dairy products pose health risks for children and encourage the development of obesity, diabetes, and heart disease.
The American Academy of Pediatrics recommends that infants below 1 year of age not be given whole cow’s milk,32 as iron deficiency is more likely on a dairy-rich diet. Cow’s milk products are very low in iron.33 If dairy products become a major part of one’s diet, iron deficiency is more likely. Colic is an additional concern with milk consumption. Up to 28 percent of infants suffer from colic during the first month of life.34Pediatricians learned long ago that cow’s milk was often the reason. We now know that breastfeeding mothers can have colicky babies if the mothers consume cow’s milk. The cow’s antibodies can pass through the mother’s bloodstream, into her breast milk, and to the baby.35,36Additionally, food allergies appear to be common results of cow’s milk consumption, particularly in children.37,38 Cow’s milk consumption has also been linked to chronic constipation in children. Researchers suggested that milk consumption resulted in perianal sores and severe pain on defecation, leading to constipation.39
It may be possible for rheumatoid arthritis (RA) and migraine sufferers to alleviate pain by eliminating dairy products (and/or other offending foods) from the diet. One of the most common dietary triggers of migraines and arthritis pain is dairy products, and even minor exposures to triggers can cause an attack.
In adults, anywhere between 20 and 50 percent have a reduction or elimination of their migraine headaches when common trigger foods, such as dairy products, are avoided.40,41
According to several studies, vegan diets appear to benefit about half of arthritis patients, including some who did not identify a specific diet trigger.42-46 A study evaluating the influence of a four-week, low-fat vegan diet on RA patients showed significant changes in symptomology, such as improvement in ability to function, a decrease in both joint tenderness and joint swelling scores, improved severity of morning stiffness, and a decrease in pain.47
Studies linking milk consumption and adolescent acne suggest that the association is caused by hormones and bioactive molecules present in cow’s milk.48-50
In a retrospective study of 47,355 women, intake of milk during adolescence was associated with a history of teenage acne, and the association was strongest with skim milk.48 Years later the same research group conducted a prospective study on 6,094 adolescent girls and found that a greater consumption of milk was associated with a higher prevalence of acne, and no association was found with milk fat.49Similarly, the researchers’ investigation on milk consumption and teenage boys yielded a positive association between skim milk and acne.50
Obesity and Calories
Obesity is a risk factor for a number of chronic diseases. Replacing high-calorie dairy products with low-calorie plant foods can assist in keeping within established calorie ranges and maintaining a healthy weight.
Ounce for ounce, colas and skim milk have about the same number of calories. Whole milk has about 50 percent more calories, and 2 percent milk has approximately one-third more calories than cola. Reduced-fat milk is the seventh leading source of calories among Americans ages 2 to 18 years old, and whole milk is 12th, according to the 2010 Dietary Guidelines for Americans.51
Milk and dairy products are not necessary in the diet and can, in fact, be harmful to health. It is best to consume a healthful diet of grains, fruits, vegetables, legumes, and fortified foods including cereals and juices. These nutrient-dense foods can help you meet your calcium, potassium, riboflavin, and vitamin D requirements with ease—and without health risks.
