Toxic substance present in peanuts increases risk of cancer

The association of consumers, an analysis of eight brands of peanut Japanese and five of the raw product showed high concentration of aflatoxin in raw peanuts Brand Kisabor.

The level of contamination is found ten times higher than the Brazilian law allows - up to 30mg of aflotoxina / kg of food. The problem was not repeated in other tested batches of the same product, but the fact that there a lot with a very high level of contamination is cause for great concern.

For Ana Carolina Gagliardi Miguel Moron, Nutrology of Incor, this is a frequent problem in Brazil. "The aflotoxinas are produced by fungi that are present in nature and in many foods such as peanuts, nuts and corn, and can be consumed in small quantities. The problem is when the food is much toxin as the Pro Test it."

Aflatoxin is a toxin derived from fungi. It is dangerous to health and potentially carcinogenic. The substance has a cumulative effect in the body and when consumed in high doses, can cause serious damage to health, such as cirrhosis, hepatitis B and hemorrhage in the kidneys. In pregnancy, aflatoxin can cause mutations in the fetus.

A Pro test asked the National Health Surveillance Agency (Anvisa) and the Ministry of Agriculture and the prohibition of the collection of 03,073 batch of raw peanuts Kisabor. The agency promised that it will take action.

In previous years, lots of other foods made with peanuts were prohibited.

Cream for skin cancer may improve the appearance of wrinkles, study suggests

A cream used to treat pre-cancerous lesions of the skin also reverses
signs of aging, study of American scientists has revealed. Besides
to remove protuberances suspected skin damaged by sun, drugs
fluorouracil improves the appearance of wrinkles, dark spots and olheiras.

Patients with pre-cancerous actinic keratosis (patches that are distinguished
only by the tan disappear by surgery or chemical treatment)
can expect, as a side effect of treatment, have a skin
look younger, according to articles written by researchers
in the medical journal "Archives of Dermatology."

Experts warn, however, against the use of drugs for
purely cosmetic purposes, saying it can cause severe
reaction in the skin. The treatment encourages the body to produce new skin
healthy to deliberately damage the outer most layer of skin,
well as in chemical peeling and laser treatment.

In tests with 21 volunteer patients with actinic keratosis
and skin damaged by exposure to the sun, the scientists applied cream
with fluorouracil twice daily for two weeks and found a
significant improvement in the skin, with the removal of stains and pre-cancerous
the reversal of some signs of injuries caused by the sun.

The team of scientists led by Dana Sachs, the School of Medicine
University of Michigan in Ann Arbor, said: "Without doubt, there
patients who want a therapy as the application of fluorouracil to
cosmetic purposes because of the relatively low cost of this therapy in
compared to the use of laser. "Sachs added that this strategy,
however, "can not achieve the same degree of improvement" achieved with the
Laser treatment of wrinkles.
