Got Milk?

 

Oh, good old dairy! I’m sure you remember being a kid and having your mother tell you, Drink your milk! You need it to grow and be strong! Or perhaps your mom was ahead of the curve and saw through the mass marketing campaign designed to convince us that we require milk to live a healthy life.

Aside from the obvious reasons why we don’t need cow’s milk — no other animal drinks the milk from another species; we no longer need milk once weaned from our  own mother’s; and cow’s milk is, well, meant for baby cows to grow into giant cows — we most certainly do not need dairy.

Got Milk?dai

This whole dairy façade began upon the premise that we need calcium, which we do, and that we can only get it through dairy products, which is false. There are a number of vegetables that contain even more calcium than milk, including broccoli, kale, cabbage, and watercress, along with a variety of nuts and seeds. But we never see ads on television telling us to eat our broccoli, even though it has many more health benefits than milk. Simply put, there is no lobbying behind broccoli.        More

Why Is Milk Consumption Associated with More Bone Fractures?

Michael Greger M.D. FACLM on January 31st, 2017

Milk is touted to build strong bones, but a compilation of all the best studies found no association between milk consumption and hip fracture risk; so, drinking milk as an adult might not help bones, but what about in adolescence? Harvard researchers decided to put it to the test.

Studies have shown that greater milk consumption during childhood and adolescence contributes to peak bone mass, and is therefore expected to help avoid osteoporosis and bone fractures in later life. But that’s not what researchers have found (as you can see in my video Is Milk Good for Our Bones?). Milk consumption during teenage years was not associated with a lower risk of hip fracture, and if anything, milk consumption was associated with a borderline increase in fracture risk in men.

It appears that the extra boost in total body bone mineral density from getting extra calcium is lost within a few years, even if you keep the calcium supplementation up. This suggests a partial explanation for the long-standing enigma that hip fracture rates are highest in populations with the greatest milk consumption. This may be an explanation for why they’re not lower, but why would they be higher?

This enigma irked a Swedish research team, puzzled because studies again and again had shown a tendency of a higher risk of fracture with a higher intake of milk. Well, there is a rare birth defect called galactosemia, where babies are born without the enzymes needed to detoxify the galactose found in milk; so, they end up with elevated levels of galactose in their blood, which can cause bone loss even as kids. So maybe, the Swedish researchers figured, even in normal people that can detoxify the stuff, it might not be good for the bones to be drinking it every day.

And galactose doesn’t just hurt the bones. Galactose is what scientists use to cause premature aging in lab animals—it can shorten their lifespan, cause oxidative stress, inflammation, and brain degeneration—just with the equivalent of like one to two glasses of milk’s worth of galactose a day. We’re not rats, though. But given the high amount of galactose in milk, recommendations to increase milk intake for prevention of fractures could be a conceivable contradiction. So, the researchers decided to put it to the test, looking at milk intake and mortality as well as fracture risk to test their theory. 

A hundred thousand men and women were followed for up to 20 years. Researchers found that milk-drinking women had higher rates of death, more heart disease, and significantly more cancer for each glass of milk. Three glasses a day was associated with nearly twice the risk of premature death, and they had significantly more bone and hip fractures. More milk, more fractures.

Men in a separate study also had a higher rate of death with higher milk consumption, but at least they didn’t have higher fracture rates. So, the researchers found a dose dependent higher rate of both mortality and fracture in women, and a higher rate of mortality in men with milk intake, but the opposite for other dairy products like soured milk and yogurt, which would go along with the galactose theory, since bacteria can ferment away some of the lactose. To prove it though, we need a randomized controlled trial to examine the effect of milk intake on mortality and fractures. As the accompanying editorial pointed out, we better find this out soon, since milk consumption is on the rise around the world.

What can we do for our bones, then? Weight-bearing exercise such as jumping, weight-lifting, and walking with a weighted vest or backpack may help, along with getting enough calcium (Alkaline Diets, Animal Protein, & Calcium Loss) and vitamin D (Resolving the Vitamin D-Bate). Eating beans (Phytates for the Prevention of Osteoporosis) and avoiding phosphate additives (Phosphate Additives in Meat Purge and Cola) may also help.

Maybe the galactose angle can help explain the findings on prostate cancer (Prostate Cancer and Organic Milk vs. Almond Milk) and Parkinson’s disease (Preventing Parkinson’s Disease With Diet).

Galactose is a milk sugar. There’s also concern about milk proteins (see my casomorphin series) and fats (The Saturated Fat Studies: Buttering Up the Public and Trans Fat in Meat and Dairy) as well as the hormones (Dairy Estrogen and Male Fertility, Estrogen in Meat, Dairy, and Eggs and Why Do Vegan Women Have 5x Fewer Twins?).  

Milk might also play a role in diabetes (Does Casein in Milk Trigger Type 1 Diabetes, Does Bovine Insulin in Milk Trigger Type 1 Diabetes?) and breast cancer (Is Bovine Leukemia in Milk Infectious?, The Role of Bovine Leukemia Virus in Breast Cancer, and Industry Response to Bovine Leukemia Virus in Breast Cancer).       Nutrition Facts

A glass of milk can contain a cocktail of up to 20 painkillers, antibiotics and growth hormones, scientists have shown.

A glass of milk can contain a cocktail of up to 20 painkillers, antibiotics and growth hormones, scientists have shown.

Using a highly sensitive test, they found a host of chemicals used to treat illnesses in animals and people in samples of cow, goat and human breast milk.

The doses of drugs were far too small to have an effect on anyone drinking them, but the results highlight how man-made chemicals are now found throughout the food chain.

the highest quantities of medicines were found in cow’s milk.

Researchers believe some of the drugs and growth promoters were given to the cattle, or got into milk through cattle feed or contamination on the farm.

The Spanish-Moroccan team analysed 20 samples of cow’s milk bought in Spain and Morocco, along with samples of goat and breast milk.

Their breakdown, published in the Journal of Agricultural and Food Chemistry, revealed that cow’s milk contained traces of anti-inflammatory drugs niflumic acid, mefenamic acid and ketoprofen – commonly used as painkillers in animals and people.

It also contained the hormone 17-beta-estradiol, a form of the sex hormone oestrogen. The hormone was detected at three millionths of a gram in every kilogram of milk, while the highest dose of niflumic acid was less than one millionth of a gram per kilogram of milk.

However, the scientists, led by Dr Evaristo Ballesteros, from the University of Jaen in Spain, say their technique could be used to check the safety of other types of food.

Dr Ballesteros said: ‘We believe the new methodology will help to provide a more effective way of determining the presence of these kinds of contaminants in milk or other products.

‘Food quality control laboratories could use this new tool to detect these drugs before they enter the food chain. This would raise consumers’ awareness and give them the knowledge that food is… harmless, pure, genuine, beneficial to health and free of toxic residues,’ he added.

Net result: Compounds manufactured and used by humans are showing up in all parts of the food chain

The tests also found niflumic acid in goat’s milk, while breast milk contained traces of painkillers ibuprofen and naproxen, along with the antibiotic triclosan and some hormones.

The researchers say their new 30-minute test is the most sensitive of its kind. If the findings are true for Spanish and Moroccan milk, they could equally be true for milk produced in Britain and northern Europe.

Last year Portsmouth University scientists found that fish were being contaminated with the anti-depressant Prozac.

The drug enters rivers from the sewer system and tinkers with the brain chemistry of fish, the researchers claimed.

Previous studies have shown that caffeine is released into our waterways after surviving the sewage treatment process. 

The hormones from the contraceptive pill and HRT have been blamed for feminising fish, leading to male fish producing eggs.

The effects of antibiotics, blood pressure drugs and cholesterol-lowering drugs on wildlife are also being studied around the world.                DailyMail

It is hoped fluoridated milk will tackle tooth decay

15:58Wednesday 20 January 2016

 

More than 8,000 children in Blackpool are to be offered fluoridated milk after councillors approved a proposal to introduce it to the town’s existing free breakfast scheme.

Blackpool Council’s executive agreed a recommendation after hearing the scheme would help reduce the risk of tooth decay.

It is hoped the milk, which is recommended by the World Health Organisation, will help tackle poor dental hygiene among children in the town.

Figures show almost half of 12-year-olds in Blackpool have at least one decayed, missing or filled tooth – much higher than the national average of 33 per cent.

But parents will be able to opt out if they wish.

Coun Graham Cain, cabinet secretary for Blackpool Council, said: “Unfortunately the state of Blackpool’s dental health is very poor.

“However, where some parts of the country can benefit from fluoride naturally appearing in their daily drinking water, in Blackpool we cannot.

“What we do have is a method through the free breakfast programme that allows us to reach all primary school children as they are growing up and make the fluoride milk available to them there.”

But some concerns have been raised about the proposal.

Coun Tony Williams, leader of the Conservatives on Blackpool Council, said: “Parents now have to be really assured and confident that it is the right move for their child.

“And if they don’t think it is, they need to contact their children’s school.”

The proposal was first put forward in 2013 but delayed while further studies were carried out. These found children in the town have lower than normal levels of fluoride in their bodies.

The study examined pre-school children and monitored the levels of fluoride currently in their system.

A group will now be formed combining Blackpool Council, Public Health England, Blackpool Teaching Hospitals NHS Foundation Trust and oral health charity the Borrow Foundation to oversee the application and implementation of the scheme.          The Gazette

A new study finds an intriguing link between contaminants found in milk and the risk of developing parkinson

Alice Park @aliceparkny Dec. 9, 2015

Studies have found a connection between the consumption of dairy products and a higher risk of developing Parkinson disease, the neurodegenerative disorder that affects motor neurons in the brain. While researchers speculated that chemicals found in cows’ milk might be responsible, there was little evidence to detail how dairy products like milk and cheese might be affecting people’s risk of the disease.

Now, scientists may have uncovered a promising clue. Reporting in the journal Neurology, Robert Abbott, from Shiga University of Medical Science in Japan, and his colleagues took advantage of an environmental scandal in Hawaii in the 1980s to investigate the connection. At the time, an organochlorine pesticide used by pineapple farmers made its way into the milk supply when cows were fed a gruel made in part from the pineapple debris. Coincidentally, there was also a study of heart disease among Japanese-American men begun then that involved more than 8,000 men who were followed from mid-life to death. All provided detailed information about what they ate, including how much milk they drank, and some agreed to donate their brains for research upon death.

Abbott and his team studied 449 brains and recorded the density of neurons in specific areas of the brain known to be affected by Parkinson’s. They found that men who reported drinking more than two glasses of milk a day (16 oz) showed the thinnest nerve networks in these areas, suggesting compromised function of these nerves, compared to men who drank little or no milk. The milk drinkers also had residues of specific organochlorines called heptachlor epoxide.

Interestingly, by measuring when cells in motor nerve regions died, they also learned that the accumulation of heptachlor epoxide occurred before the cells were damaged, strongly hinting that the chemical was responsible for triggering the changes associated with Parkinson’s.

Abbott says that he and his team did not have samples of the milk the men drank, so can’t say for sure that the contaminated milk was the source of the pesticides they found in the mens’ brains, but it’s a reasonable explanation. “We don’t have all the data yet, but we are close to finding the smoking gun here,” he says. “It’s not complete, but it’s very suspicious.”

Heptachlor epoxide is no longer used as an insecticide in the U.S. According to the Environmental Protection Agency, “nearly all registered uses of heptachlor epoxide have been canceled.” But it tends to be persistent, remaining in soil and water for many years. Abbott also notes that it’s been found in goat and cow milk in Ethiopia and that other organochlorines have been detected in the milk supply in Italy.

The data certainly don’t mean that anyone who drinks several cups of milk a day is putting themselves at risk of developing Parkinson’s. What it does mean is that diet and lifestyle risk factors should be considered more deeply. “This adds to the literature that diet may indeed play a role in Parkinson’s,” says Abbott. “But it also tells us that there is more to food than just its nutritional value. There’s contamination, and what’s on that food.”

For now, there’s no reasons to stop drinking milk. (“I drink a cup of milk every day,” says Abbott.) But he hopes his findings fuel the continued careful look at how chemicals in the environment might be affecting our health, even in indirect and not always obvious ways.Time
