Sunscreen chemicals absorbed into body, found in 85 percent of human milk samples

(NaturalNews) Before you apply creams, lotions, cosmetics and sunscreens to your skin, it might be a good idea to find out what's really in them. What's more, you need to know those ingredients aren't necessarily just coating the outside layers of your skin. For example, as NaturalNews previously reported, UCLA scientists have recently discovered nanoparticles in cosmetics and sunscreens can enter and wander throughout the body, potentially disrupting body functions on a sub-cellular level (http://www.naturalnews.com/027603_n...). And now, for the first time, a study just published in the international science journal Chemospherehas shown that a group of chemicals known as UV (for ultraviolet radiation) filters are turning up in humans internally -- and the phenomenon is widespread.

In fact, the investigation, conducted by a Swiss National Research Program called Endocrine Disrupters: Relevance to Humans, Animals and Ecosystems, found UV filters, which are common in cosmetics and sunscreens, were present in 85 percent of human milk samples tested. What does this mean for adults, much less babies taking in this contaminated milk? The alarming truth is, no one knows.

For the study, during the fall and summer of 2004, 2005 and 2006, human milk was sampled from mothers who had given birth at the University Women's Hospital in Basel, Switzerland. The research participants also answered detailed questionnaires in order to document their use of different types of cosmetic products and sunscreens.

When the women's breast milk was analyzed, tests revealed the milk samples contained a huge list of chemicals including persistent organic pollutants (POPs), synthetic musk fragrances, pesticides, phthalates, parabens, flame retardants (polybrominated diphenylethers), polychlorinated biphenyls (PCBs) -- and cosmetic UV filters. What's more, the UV filter chemicals were surprisingly widespread; they were comparable in concentrations to PCBs, which have long been known to contaminate the environment.

"Research on the effects of endocrine disrupters (chemicals interfering with hormone actions) has shown that it is of utmost importance to obtain information on simultaneous exposure of humans to different types of chemicals because endocrine active chemicals can act in concert. Information on exposure is particularly important for the developing organism at its most sensitive early life stages. Human milk was chosen because it provides direct information on exposure of the suckling infant and indirect information on exposure of the mother during pregnancy," research team leaders Margret Schlumpf and Walter Lichtensteiger said in a media statement.

The analyzed data of the milk samples obtained from individual mothers were then compared with the information collected through the questionnaire about cosmetic and sunscreen use. While exposure patterns differed between individuals, Dr. Schlumpf, who is a scientist at the University of Zurich, pointed out that the total reported use of products containing UV filters was significantly correlated with the presence of those chemicals in breast milk.

In all, a total daily intake of each individual chemical found in the breast milk tests was calculated for each baby who was fed with breast milk. The results showed some infants were taking in daily amounts of PCBs and several pesticides that were far above the U.S. Environmental Protection Agency (EPA) reference for supposed "acceptable" levels. Little is known about the health significance of babies drinking in UV filters through their mothers' milk.

In a statement to the media, the scientists noted that information on the relationship between the exposure of human populations to ingredients in cosmetics and sunscreens and the presence of these constituents in the human body has been sorely limited. And before the new Swiss research findings, the data on UV filters being present inside the human body was virtually non-existent.

"This study once again emphasizes the importance of global research on the impact of contaminants in the human environment and the need for continuous critical assessment of our priorities in environmental health and consumer habits. I am sure that this investigation will also spark debate at the upcoming first Environmental Health conference in Brazil, February 2011", Gert-Jan Geraeds, Executive Publisher of Chemosphere said in a press statement.

Men may be able to grow a new pancreas from their testicles

Topflight geneticists say they have managed to cure diabetes in mice by grafting material from dead men's testicles onto them. The development may mean that in future, human (male) diabetes sufferers can in effect grow a replacement bollock-based pancreas from such tissues.

According to an announcement from the lab involved, headed “Grow Your Own Transplant”:

Life Expectancy in US Drops Slightly

U.S. life expectancy has dropped slightly - by about a month - after mostly inching up for many years, the government reported Thursday. The preliminary report indicates that a baby born in 2008 can expect to live to 77.8 years if current trends continue. That's down a bit from an all-time high of 77.9 years for 2007. A similar dip occurred in 2005, and life expectancy also dropped in 1993. MORE>>>>

FDA Re-examines Metal Fillings Decision

U.S. health regulators are seeking a second opinion on whether mercury-containing dental fillings pose a risk to dental patients, especially children and pregnant women. Food and Drug Administration officials said that while there are no new scientific findings on such silver-colored cavity fillings, it wants feedback on methods it used to weigh available data and decide last year that the metal alloy is safe.

Why Butter is Better for Your Health Today

By The Weston A. Price Foundation

The Weston A. Price Foundation provides accurate information about nutrition and is dedicated to putting nutrient-dense foods back on American tables.

Are you still shunning butter from your diet? You can stop today because butter can be a very healthy part of your diet.

Why Butter is Better

  • Vitamins ...

    Butter is a rich source of easily absorbed vitamin A, needed for a wide range of functions, from maintaining good vision to keeping the endocrine system in top shape.

    Butter also contains all the other fat-soluble vitamins (D, E and K2), which are often lacking in the modern industrial diet.

  • Minerals ...

    Butter is rich in important trace minerals, including manganese, chromium, zinc, copper and selenium (a powerful antioxidant). Butter provides more selenium per gram than wheat germ or herring. Butter is also an excellent source of iodine.

  • Fatty Acids ...

    Butter provides appreciable amounts of short- and medium-chain fatty acids, which support immune function, boost metabolism and have anti-microbial properties; that is, they fight against pathogenic microorganisms in the intestinal tract.

    Butter also provides the perfect balance of omega-3 and omega-6 fats. Arachidonic acid in butter is important for brain function, skin health and prostaglandin balance.

  • Conjugated Linoleic Acid (CLA) ...

    When butter comes from cows eating green grass, it contains high levels of conjugated linoleic acid (CLA), a compound that gives excellent protection against cancer and also helps your body build muscle rather than store fat.

  • Glycospingolipids ...

    These are a special category of fatty acids that protect against gastrointestinal infections, especially in the very young and the elderly. Children given reduced-fat milks have higher rates of diarrhea than those who drink whole milk.

  • Cholesterol ...

    Despite all of the misinformation you may have heard, cholesterol is needed to maintain intestinal health and for brain and nervous system development in the young.

  • Wulzen Factor ...

    A hormone-like substance that prevents arthritis and joint stiffness, ensuring that calcium in your body is put into your bones rather than your joints and other tissues. The Wulzen factor is present only in raw butter and cream; it is destroyed by pasteurization.

Butter and Your Health

Is butter really healthy? Let us count the ways …

  1. Heart Disease

    Butter contains many nutrients that protect against heart disease including vitamins A, D, K2, and E, lecithin, iodine and selenium. A Medical Research Council survey showed that men eating butter ran half the risk of developing heart disease as those using margarine (Nutrition Week 3/22/91, 21:12).

  2. Cancer

    The short- and medium-chain fatty acids in butter have strong anti-tumor effects. Conjugated linoleic acid (CLA) in butter from grass-fed cows also gives excellent protection against cancer.

  3. Arthritis

    The Wulzen or "anti-stiffness" factor in raw butter and also Vitamin K2 in grasss-fed butter, protect against calcification of the joints as well as hardening of the arteries, cataracts and calcification of the pineal gland. Calves fed pasteurized milk or skim milk develop joint stiffness and do not thrive.

  4. Osteoporosis

    Vitamins A, D and K2 in butter are essential for the proper absorption of calcium and phosphorus and hence necessary for strong bones and teeth.

  5. Thyroid Health

    Butter is a good source of iodine, in a highly absorbable form. Butter consumption prevents goiter in mountainous areas where seafood is not available. In addition, vitamin A in butter is essential for proper functioning of the thyroid gland.

  6. Digestion

    Glycospingolipids in butterfat protect against gastrointestinal infection, especially in the very young and the elderly.

  7. Growth & Development

    Many factors in the butter ensure optimal growth of children, especially iodine and vitamins A, D and K2. Low-fat diets have been linked to failure to thrive in children -- yet low-fat diets are often recommended for youngsters!

  8. Asthma

    Saturated fats in butter are critical to lung function and protect against asthma.

  9. Overweight

    CLA and short- and medium-chain fatty acids in butter help control weight gain.

  10. Fertility

    Many nutrients contained in butter are needed for fertility and normal reproduction.

Why You Should Avoid Margarine, Shortening and Spreads

There are a myriad of unhealthy components to margarine and other butter imposters, including:

  • Trans fats: These unnatural fats in margarine, shortenings and spreads are formed during the process of hydrogenation, which turns liquid vegetable oils into a solid fat

    Trans fats contribute to heart disease, cancer, bone problems, hormonal imbalance and skin disease; infertility, difficulties in pregnancy and problems with lactation; and low birth weight, growth problems and learning disabilities in children.

    A U.S. government panel of scientists determined that man-made trans fats are unsafe at any level. (Small amounts of natural trans fats occur in butter and other animal fats, but these are not harmful.)

  • Free radicals: Free radicals and other toxic breakdown products are the result of high temperature industrial processing of vegetable oils. They contribute to numerous health problems, including cancer and heart disease.
  • Synthetic vitamins: Synthetic vitamin A and other vitamins are added to margarine and spreads. These often have an opposite (and detrimental) effect compared to the natural vitamins in butter.
  • Emulsifiers and preservatives: Numerous additives of questionable safety are added to margarines and spreads. Most vegetable shortening is stabilized with preservatives like BHT.
  • Hexane and other solvents: Used in the extraction process, these industrial chemicals can have toxic effects.
  • Bleach: The natural color of partially hydrogenated vegetable oil is grey so manufacturers bleach it to make it white. Yellow coloring is then added to margarine and spreads.
  • Artificial flavors: These help mask the terrible taste and odor of partially hydrogenated oils, and provide a fake butter taste.
  • Mono- and di-glycerides: These contain trans fats that manufacturers do not have to list on the label. They are used in high amounts in so-called "low-trans" spreads.
  • Soy protein isolate: This highly processed powder is added to "low-trans" spreads to give them body. It can contribute to thyroid dysfunction, digestive disorders and many other health problems.
  • Sterols: Often added to spreads to give them cholesterol-lowering qualities, these estrogen compounds can cause endocrine problems; in animals these sterols contribute to sexual inversion.

How to Purchase Butter

The BEST butter is raw butter from grass-fed cows, preferably organic. Next is pasteurized butter from grass-fed cows, followed by regular pasteurized butter from supermarkets. Even the latter two are still a much healthier choice than margarine or spreads.

Scientists Raise More BPA Concerns

Scientists at Tufts University School of Medicine have published a study that raises new concern about the effects of the ever-present chemical bisphenol A (BPA), especially the effect on pregnant women.

"Mice exposed to BPA in the womb and during nursing subsequently had fewer successful pregnancies and delivered fewer pups over the course of the study," reported one of the study's co-senior authors, Ana M. Soto, MD, professor of anatomy and cellular biology at Tufts University School of Medicine (TUSM) and member of the cell, molecular and developmental biology program faculty at the Sackler School of Graduate Biomedical Sciences.

The study may add ammunition to those who want BPA banned. Sen. Diane Feinstein (D-CA) pushed to ban BPA in infant bottles and Sippy cups, as part of the recently passed Food Safety and Modernization Bill. Her amendment provoked such strong food industry opposition that the measure did not pass until she dropped that provision.

BPA is a chemical added to plastic to make it rigid. Though it is slowly being phased out, it has had widespread use in beverage bottles and food containers. Recent studies have found that the chemical is present in many consumers' bodies.

Decreased fertility

In the Tufts study, fertility decreased over time in female mice that had been exposed during fetal and neonatal (perinatal) development to doses of BPA that were lower than or equal to human environmental exposure levels.

At the highest of three doses tested, only 60 percent of the BPA-exposed mice had four or more deliveries over a 32-week period, compared with 95 percent in the unexposed control group. Decline of the reproductive capacity of the female mice in this study was not obvious at first pregnancy, when the animals were very young, but manifested later in life with a decline in number of pups born per delivery.

"This finding is important because standard tests of reproductive toxicology currently consist of assessing the success of a first pregnancy in young animals. If subsequent pregnancies are not examined, relevant effects may be missed," said co-senior author Beverly S. Rubin, PhD, associate professor of anatomy and cellular biology at TUSM and member of the cell, molecular and developmental biology and neuroscience program faculties at the Sackler School.

The authors say their findings are potentially of great relevance to humans because BPA is used in the production of materials people are exposed to every day, such as polycarbonate plastics and the resins used to coat the inside of food and beverage cans.

The scientist say BPA has effects that mimic those of estrogen, a natural hormone. Fetal and neonatal exposure to BPA has been shown to have other hormone-related effects in rodents, including increased risk of mammary and prostate cancers, altered behavior, and obesity.

BPA has been found in the urine of over 92 percent of Americans tested, with higher levels in children and adolescents relative to adults. It has also been detected in human maternal and fetal plasma, the authors said.
