Toronto, November 16, 2016: Diets rich in fat can bring such changes in the bacterial communities of your gut that they can eventually increase risk of developing age-related macular degeneration (AMD) or aggravate the blinding disease, warns a study.

Bacteria in your intestines may play an important role in determining if you will develop blinding wet AMD – late form of the disease, said the study published in the journal EMBO Molecular Medicine.

“Our study suggests that diets rich in fat alter the gut microbiome in a way that aggravates wet AMD, a vascular disease of the aging eye,” said lead researcher Przemyslaw (Mike) Sapieha, Professor at University of Montreal in Canada.

“Influencing the types of microbes that reside in your gut either through diet or by other means may thus affect the chances of developing AMD and progression of this blinding disease,” Sapieha noted.

AMD is characterised by a heightened immune response, sizeable deposits of fat debris at the back of the eye called soft drusen (early AMD), destruction of nerve cells, and growth of new diseased blood vessels (wet AMD, late form).

While only accounting for roughly 10 per cent of cases of AMD, wet AMD is the primary form leading to blindness.

Current treatments becomes less effective with time. It is therefore important to find new ways to prevent the onset of this debilitating disease.

The researchers found that changes in the bacterial communities of your gut, such as those brought on by a diet rich in fat, can cause long-term low-grade inflammation in your whole body and eventually promote diseases such as wet AMD. (IANS)

Make-up Products Contain Dangerous Bacteria: Study

Life-threatening bacteria found in Make-up products

The vast majority of in-use make-up products such as beauty blenders, mascara and lip gloss are contaminated with potentially life threatening superbugs, researchers have warned.

“Make-up products used every day by millions of people in the UK are contaminated with potentially deadly bugs, such as E.coli and Staphylococci, because most are not being cleaned and are used far beyond their expiry dates,” said study lead author Amreen Bashir from Aston University in the US.

According to the study published in the Journal of Applied Microbiology, bacteria that can cause illnesses ranging from skin infections to blood poisoning if used near eyes, mouth or cuts or grazes were found in nine out of ten of the products.

This risk is amplified in immunocompromised people who are more likely to contract infections from opportunistic bacteria.

The relatively new beauty blenders – sponges used to apply skin foundation products – were found to have the highest levels of potentially harmful bacteria – with the vast majority (93 per cent) not having ever been cleaned, despite more than two thirds (64 per cent) being dropped on the floor at some point during use.

The research looked at beauty blender products – hugely popular make-up sponges used to blend foundation and contouring on the face.

Often endorsed by celebrities, these sponges are estimated to have sold over 6.5 million worldwide.

The researchers found these products are particularly susceptible to contamination as they are often left damp after use, which creates an ideal breeding ground for harmful bacteria.

“Consumers’ poor hygiene practices when it comes to using make-up, especially beauty blenders, is very worrying when you consider that we found bacteria such as E.coli – which is linked with faecal contamination – breeding on the products we tested,” Bashir said.

The findings reveal that consumers are unwittingly putting themselves at risk, and that manufacturers and regulatory bodies should do more to protect their customers by making expiry dates and cleaning requirements more prominent on packaging.

EU guidance holds make-up brands to strict hygiene standards of manufacture and states that E.coli in particular should not be found in any concentration in new cosmetic products.

However, there is currently limited consumer protection around the risks of contaminating products while in use.

According to the study, post-Brexit, UK consumers could be at even greater risk as they will no longer be protected by EU regulations and could find themselves purchasing more beauty products from the US – for example – where there are no regulatory requirements to put expiry dates on make-up packaging at all.
