How Fat May Hurt the Brain, and How Exercise May Help

How Fat May Hurt the Brain, and How Exercise May Help | current events | Scoop.it

Obesity may have harmful effects on the brain, and exercise may counteract many of those negative effects, according to sophisticated new neurological experiments with mice, even when the animals do not lose much weight. While it’s impossible to know if human brains respond in precisely the same way to fat and physical activity, the findings offer one more reason to get out and exercise.

It’s been known for some time that obesity can alter cognition in animals. Past experiments with lab rodents, for instance, have shown that obese animals display poor memory and learning skills compared to their normal-weight peers. They don’t recognize familiar objects or recall the location of the exit in mazes that they’ve negotiated multiple times.

But scientists hadn’t understood how excess weight affects the brain. Fat cells, they knew, manufacture and release substances into the bloodstream that flow to other parts of the body, including the heart and muscles. There, these substances jump-start biochemical processes that produce severe inflammation and other conditions that can lead to poor health.

Many thought the brain, though, should be insulated from those harmful effects. It contains no fat cells and sits behind the protective blood-brain barrier that usually blocks the entry of undesirable molecules.

However, recent disquieting studies in animals indicate that obesity weakens that barrier, leaving it leaky and permeable. In obese animals, substances released by fat cells can ooze past the barrier and into the brain.

Rosmellin Barrios's insight:

I thought this article was very interesting because there was a lot of information. Obesity is a huge problem here in the U.S. I was actually impressed when i was reading this article and it said about how obesity could actually affect your brain. Fat cells manufacture and release substances into the blood stream which affect your brain. An experiment was done on mice and you were actually able to tell the difference from the normal average weight mice and the obese mice.

Lifestyle Factors Affecting Your Skin Health

Lifestyle Factors Affecting Your Skin Health | current events | Scoop.it
Most of us follow a cleansing, toning, moisturising routine and use sunscreens. But, our skin health is a reflection of our internal wellness. Our lifestyle, i.e., food and exercise impact our skin.
Rosmellin Barrios's insight:

I thought this article was very interesting. It is about how it does not matter what type of cleanser or moisturizer you use on your skin. If you are stressed or are not eating well or your suffering from sleep deprivation it will reflect on your skin. One thing that could occur is that you will age much more faster. Another is hair loss. It is normal to lose hair but you lose even more when you are under stress. These ar very important factors that even reflect on your appearance. Therefore we should take care of oursleves inside and outside.  You could be using the most expensive products but if your not exercising, you have bad eating habits, and you dont sleep enough it will all show on your skin.

New Jersey Could Mandate Social Media Education for Middle Schools

The proposed law aspires to reduce cyberbullying and instill social media ethics in kids.
Rosmellin Barrios's insight:

I bellieve kids should not be  on the web at a very young age. They could become victims of cyber bullying or them themselves could become a bullly. The web is not just used to do research its also used to cyber bully. This can affect the victim in many ways. Something that also affects children ver much is the social media. These are things that children shouldn't even have to worry about. We live in a society in which it does not matter how old you are because everyone is involved with the social media and shouldn't be like this.

N.S. boy bullied over prosthetic eye says school not doing enough ...

A 12-year-old Nova Scotia boy who lost an eye to cancer says he's being bullied in class and the school is not doing enough to help him.
Rosmellin Barrios's insight:

This current event is about a young ltwlve year old which is bullied in school. He had lost one of his eyes because of cancer. Several times he tried to explain why he only had one eye to his classmates and they would stop bullying him for one day and by the next day they would continue. The school should act and make sure this boy is comfortable in school. Thats why you hear so many cases of children not wanting to go to school or sometimes even commiting suicide.
