Hello to all the fans of “Blog del Runner”. Today we are going to talk about COW’S MILK vs BREAST MILK Governments and many entities around the world promote the consumption of milk and dairy products, making a disproportionate exaltation of their benefits. This induces millions of people to make an uncontrolled and excessive consumption of them. Despite all the scientific evidence that challenges the supposed benefits of milk, not only because they are questioned, but also because they have been shown to pose significant health risks. Definition of milk: “White liquid secreted by the breasts of female mammals to feed their offspring.” Each species produces milk with a composition adapted to the particular needs of its offspring. We are the only species that consumes milk from another species. Differences & Nutritional Values Mother’s milk VS Cow’s milk BREAST MILK & PROTEIN 👍 It does not have allergizing proteins, cow protein does. 👍 Lower protein content, 1.10g./100ml. vs. 3.5g./100ml. in cow. 👍 Of all its proteins, casein (beta casein) is only present with 40% as opposed to 80% for cow. 👍 Does not contain beta-lactoglobulin, cow’s does. Contains lactoferrin which remains present throughout lactation, and in cow’s milk decreases greatly throughout lactation. 👍 Lysozyme protein is present in human milk and absent in cow’s milk. (has pathogenic action and activates white blood cells) 👍 Lactoperoxidase is almost non-existent in human milk (if it is in saliva, on the other hand it is very abundant in cow’s milk 👍 It has vitamins in the right concentration for the development of the infant. 👍 Rich in immunoglobulins such as Ig A, which inhibits with its action the colonization of pathogens in the infant’s intestinal mucosa. BREAST MILK & MINERALS 👍 It is three times less rich in minerals, especially low in sodium, which prevents a kidney overload in the infant. 👍 It has a high bioavailability of minerals (such as calcium, iron, magnesium copper and zinc) compared to cow’s milk. 👍 The calcium-phosphorus ratio is 2:1. Cow’s milk is richer in phosphorus, so it is decompensated. 👍 Iron is absorbed by 50%, iron in cow’s milk by only 10%. 👍 Zinc concentrations are not high, but are sufficient given their high bioavailability. 👍 There are other minerals with very low concentrations in breast milk, but compared to cow’s milk they are highly superior. BREAST MILK & NON-PROTEIN NITROGEN 👍 We found amino sugars, free amino acids (taurine, glutamine), carnitine, polyamides, nucleotides and peptides Necessary for the maturation of the central nervous system and the retina, , and for the synthesis of brain lipids, etc. All in the correct proportion for the optimal development of the infant. BREAST MILK & FATS (LIPIDS) 👍 The main lipids are triglycerides (99%), phospholipids, fatty acids and sterols. 👍 It is rich in essential fatty acids Omega 3 and Omega 6. COW MILK
HEALTH RISKS COW’S MILK & OSTEOPOROSIS DECOMPENSATED MINERALS In order for there to be good absorption of calcium by the body, there must be a correct relationship between calcium and phosphorus in the food. Being the appropriate ratio of 2 calciums to 1 phosphorus. (1-2) In cow’s milk the amount of phosphorus is higher and we need more calcium to assimilate the phosphorus. This calcium is extracted from our reserves in the bones, producing decalcification. Clinical research shows that dairy products have no effect on bones. (1) A study published in 2005 in the medical journal “Pediatrics” showed that milk consumption does not improve bone structure in children. (2) A study of more than 72,000 women aged 18 and over also showed that increased milk consumption had no protective effect against the risk of fracture. (7-8) We can lower the risk of osteoporosis by reducing sodium in the diet, increasing fruit and vegetable intake, and ensuring adequate calcium intake from vegetables (e.g., kale, broccoli, and other leafy green vegetables and legumes). We can also use calcium-enriched products such as cereals and beverages. (4-6) STUDIES WITH CHILDREN AND ADULTS HAVE SHOWN THAT PHYSICAL EXERCISE HAS A GREAT EFFECT ON BONE DENSITY BY INCREASING IT. (52) The most developed countries, where large amounts of milk and milk products are consumed, have the highest rates of osteoporosis, while countries that consume moderate amounts of osteoporosis have the lowest rates of disease. (53) The consumption of high and prolonged doses of calcium can alter the mechanism of regulation and natural assimilation of the organism. This means that the body loses its optimal natural capacity to absorb calcium, and fails to recognize when it should be absorbed and how much it would be necessary for the bones. COW’S MILK & ACID BALANCE – BASE EXCESS PROTEIN Cow’s milk has more protein than women’s milk (3-1). Excess protein, in particular casein, which is the most abundant protein in cow’s milk with 87%, acidifies our body and can be the cause of numerous diseases. COW’S MILK & CANCER (16-17) Prostate cancer and breast cancer are associated with the consumption of dairy products, , which is presumably due to an increase in a hormone, which is “insulin-like growth factor” (IGF-I) This hormone is contained in cow’s milk and is detected at elevated levels in the blood of people who regularly consume dairy products. (20) Approximately 65% of the estrogen in the diet comes from dairy products. Estrogens (and their metabolites) are a risk factor for breast, ovarian and prostate cancer, as they have the ability to influence cell growth. COW’S MILK & VITAMIN D Increasing the consumption of milk or dairy products by the contribution that can provide us with vitamin D, can be counterproductive in the long run. (27) Vitamin D can be obtained from even healthier and more natural resources. The natural source of vitamin D is sunlight. A 15-minute daily exposure to the sun on the arms and legs or hands, face and arms is sufficient to meet the body’s needs for vitamin D, depending on the person’s skin colour. Fortified products such as cereals, grains, bread, orange juice and vegetable milks are healthy foods and contain vitamin D. COW’S MILK & LACTOSE INTOLERANCE LACTOSE INTOLERANCE IS THE INABILITY TO DIGEST MILK SUGAR (LACTOSE) IN THE INTESTINE DUE TO A LACK OF THE ENZYME LACTASE. (26) When we reach the age of two years we do NOT need so much breast milk for growth and the intestines begin to produce less lactase. Also, as we age, many of us lose that capacity. Without this enzyme we cannot digest lactase (milk sugar), which causes symptoms such as gastrointestinal discomfort, diarrhea and abdominal distension, that is, what we know as lactose intolerance. (24-25) Lactose intolerance is often a fact of life in different towns and affects affects about 95% of Asian Americans, 80% to 100% Native Americans, 60% to 80% of African Americans, 50% to 80% of Hispanics, and 15% of Caucasians. COW’S MILK & CONTAMINATIONS Cow’s milk contains hormones and growth factors that occur in the cow’s body naturally, as well as a number of impurities, ranging from pesticides to certain medications. (28) Many countries also incorporate additional synthetic hormones, , such as recombinant bovine growth hormone (rBGH) which is injected into dairy cows to increase milk production. The result of this process is very often mastitis or inflammation of the mammary glands, which is very painful with the corresponding infection. As a consequence of this infection, the milk can carry the pus as an aggregate. Mastitis treatments require the use of antibiotics. Therefore, it is not surprising that traces of antibiotics are found in milk samples and other dairy products. (29) Pesticides, polychlorinated biphenyls (PCBs) and dioxins are other examples of impurities in milk. These toxins CANNOT be easily eliminated by the body, so over time there is an accumulation of high concentrations affecting the immune, nervous and reproductive systems. (66) A large-scale investigation on milk resulted, for any type of milk, in the detection of 20 fixed synthetic chemicals. The chemicals found are: antibiotics, non-steroidal anti-inflammatory drugs, analgesics, anti-epileptics, preservatives, hypolipemiant drugs, beta-blockers and synthetic sex hormones. PCBs and dioxins are carcinogenic elements, i.e. substances that cause cancer. This happens especially when most of the diet is based on the consumption of animal protein. (67) According to a study by the Swiss Federal Office of Public Health (BAG) 92% of all toxins toxins (dioxins and PCBs) are found in animal feed. The largest supplier of toxins is milk, with 47%. COW’S MILK & DIABETES (30) Insulin-dependent (childhood onset) type I diabetes is associated with consumption of dairy products. (31) In a 2001 study of 3,000 children in Finland, it was shown, shown that early feeding with cow’s milk leads to increased susceptibility to type I diabetes in children. (70, 71) Several studies also show the relationship between high consumption of dairy products and type II diabetes in adulthood. Finland is one of the countries with the highest consumption of milk and dairy products in the world 252 kg/inhabitant in the year 2000) had the world’s highest rates of diabetes. (74) Spain in the same year, as one of the countries with the lowest consumption of milk and dairy products (125 kg/inhabitant in the year 2000) had one of the lowest rates of diabetes in the world. COW’S MILK & CHILDREN’S HEALTH Milk protein, lactose, fat and saturated fat in dairy products cause significant health risks to children and promote the development of obesity, diabetes and heart disease. (75) A study has shown that increased consumption of animal proteins, especially in the early stages of life, promotes the development of obesity and insulin resistance. Cow’s milk products have a very low iron content, so a diet rich in milk and dairy products may lead to iron deficiency in the child. (32-33) PLUS… (34) Colic is another problem with milk consumption. Up to 28% of children suffer from colic during the first months of life. Pediatricians are aware that cow’s milk is often the reason. …AND ALSO Cow’s milk is associated with chronic constipation in children. Researchers assure that its consumption leads to inflammation in the anus and consequent pain during evacuation. (39) COW’S MILK & OBESITY Obesity is a risk factor for a number of chronic diseases and dairy products are high in calories and favour obesity. Coca-Cola is known to be a pump of sugar and calories. Well, whole milk with 58 calories per 100g has about a third more calories than this. Milk and dairy products are not only unnecessary in the diet, but can also be very harmful to health. THE BEST DIET The best diet is a healthy diet based on cereals, fruits, vegetables, legumes and fortified foods such as cereals and juices. These nutrient-rich foods ensure that we easily get enough calcium, potassium, riboflavin, and vitamin D without risking our health. If you liked this video dale al like.
