Multe persoane nu reusesc sa slabeasca din cauza asa-numitelor calorii chimice – substante prezente in multe produse cosmetice si care tulbura echilibrul natural al organismului – afirma un recent studiu american.

Una dintre clasele de ingrediente implicate in acest fenomen sunt ftalatii, prezenti in 70% dintre produsele cosmetice, ca si in multe produse folosite pentru igiena locuintei. Aceste substante sunt absorbite de organismul uman si au efect perturbatoare foarte ingrijoratoare.

Medicii de la spitalul Mount Sinai din New York afirma ca ftalatii deregleaza mecanismul natural de control al greutatii, care tine de un delicat echilibru hormonal.

Ei sustin ca expunerea la ftalati, datorita folosirii cosmeticelor (inclusiv sapun, sampon, lotiuni de corp) determina o crestere a riscului de aparitie a obezitatii atat in copilarie, cat si la varsta adulta.

Analiza continutul de ftalati din urina, la un grup de tinere fete din cartierul East Harlem, a aratat ca acelea care aveau greutatea cea mai mare aveau si cea mai mare concentratie de ftalati in urina.

O alta substanta, numita bisfenol-A (Bisphenol A - BPA), prezenta in recipientele din material plastic, furnizeaza, de asemenea, "calorii chimice" care contribuie la cresterea in greutate, din cauza dereglarilor hormonale pe care le produce, atat la femei, cat si la barbati.

Getting fat? Blame it on ‘chemical calories’ in beauty products

London, July 11 (2011): A new study has found that the reason most of us are unable to shed the fat in our body, is because of the “chemical calories” present in beauty products such as shampoo, body lotions and soap that we use.

Doctors at the Mount Sinai Medical Center in New York claim that phthalates, chemical ingredients in 70 percent of cosmetics as well as many household cleaning products, are responsible for throwing the body’s natural weight control system, a delicate balance of hormones, off kilter.

The researchers suggested that once exposed to phthalates through daily use of such beauty products, the chances of childhood obesity and weight problems in adults become high.

The researchers meted out the study on girls living in the inner city area of East Harlem, by measuring their exposure to phthalates and analysing the children’s urine.

“The heaviest girls have the highest levels of phthalates in their urine,” the Daily Mail quoted Professor Philip Landrigan, a paediatrician and the study author, as saying.

“It goes up as the children get heavier, but it’s most evident in the heaviest kids,” he added.

Another substance, Bisphenol-A (BPA), also present in containers and bottles, has also been found to provide “chemical calories”.

It’s the fact they are absorbed into the body that causes most concern. Billed as “endocrine disruptors”, they are known to affect the glands and hormones that regulate numerous bodily functions.

According to Zoe Harcombe, nutritionist and author of the Obesity Epidemic, even the slightest disruption to hormone levels “is very bad news” for someone trying to lose weight.

“In men, phthalates and other chemicalshave an anti-testosterone capacity that has been linked to obesity,” she said.

“In womenthey mess up our basic genetic hormone balance so that you get disruptions similar to those that might occur during the menopause or at puberty,” she added. (ANI)
