Berries, apples and tea can do wonders for your brain

If you'e looking for an easy way to keep your brain healthy, consider eating more berries, consuming more applies and drinking tea. There's good science to support the benefits of getting started early eating a healthy diet for preventing Alzheimer's disease and other forms of dementia. 
Alzheimer's risk significantly lower for older adults who consume these foods
Tufts University scientists looked at Alzheimer's disease risk among older adults and compared those that consumed scant amounts of apples, tea and berries that are loaded with antioxidants; published in the Journal of Clinical Nutrition. 
The study finding was based on conclusions extracted from dietary questionairres submitted during medical exams among heart disease risk patients participating in the Framingham Heart Study. 
One of the important highlights of this study, compared to others is that the risk of the brain disease was analyzed over a 20 year period, versus short term studies that have been pub…

Another reason skipping vaccines is a bad idea: Measles wipes out immunity

Vaccine safety has become a hot topic for parents who insist on not having their children vaccinated. As an RN I'm openly opposed to anyone that thinks skipping childhood vaccinations is a good idea. A new study highlights the ongoing harm to a child's immune system once they're infected with the measles.

Measles destroys pre-existing antibodies

The finding that is published today in the journal Science describes how the measles virus destroys immunity a child has against other bacteria and viruses. In essence, getting the measles makes your child more susceptible to chicken-pox because the virus destrtoys pre-existing antibodies. But that's not all.

The study, led by a team of researchers at Harvard Medical School, Brigham and Women's Hospital and the Harvard T.H. Chan School of Public Health revealed measles can make children 11 to 73 percent more susceptible to everything from the flu to infections of the skin; including the herpes virus.

Taking a chance that a child could die or suffer pneumonia or brain damage is bad enough. Understanding that measles destroys immunity for months and possibly years should make 'anti-vaxers' take note.

One of the studies that involved Michael Mina, a Harvard virologist, examined blood samples from 77 children before and after they became infected with measles during an outbreak in the Netherlands in 2013; using a technique called VirScan.

"These were really healthy kids, said Mina. After the [measles], the children lost an average of about 20 percent of their antibody repertoire." 
Some children lost up to 70 percent of their immunity to other pathogens. A child vaccinated previously for mumps could get the mumps again if exposed.

"It's like taking somebody's immune system and rewinding time, putting them at a more naive state," says Mina. 
The measles vaccine did not have the same adverse effect on immune system 'memory'. The study instead showed, as previously thought, that the measles vaccine appeared to boost the immune system in infants and children, though the authors wrote: "...we cannot definitvely rule out the potential for minor reductions of antibody producing cells with measles vaccination."

A sobering fact published by the study authors includes that measles accounts for 100,000 deaths annually, often from secondary infections. This finding,  for any rational parent, is even more reason to understand that skipping vaccines is a really bad idea.

Can you eat square or heart shaped Japanese watermelon?

Have you ever wondered if Japanese square watermelon tastes good?  What about heart shaped watermelon? Are Japanese watermelons edible? 

According to a new report from EmaxHealth.com, the fruits are not tasty. Watermelon has many known health benefits, but when you mess with mother nature to make a cubed or heart shaped watermelon you lost taste.

Why is it done?

According to EmaxHealth reporter Tamar Najarian:
"...by the time it [square watermelon] is the proper shape, it has not been given the time needed to also mature. As such, one can buy a non-edible square watermelon for nearly $100 from posh upscale supermarkets and use it as decoration or gifts that could last up to a year or more."  In Najarian's opinion that makes square watermelons pretty useless, despite the fact that they're produced to make them easier to store.. 

You can even grow your own square watermelon,

Heart shaped watermelon tasty

If you want something different to give as a gift, you could offer heart…

Better Health Through Compassion - Bloggers Unite for Refugees

There's no question that we can learn, but can we translate our learning into action? We face disasters, and none of us are immune. Hunger, climate change, and the threat of displacement from war and natural disasters are real. You could easily become a victim.

We are not disempowered. Helping others means learning more about what goes on in the world, and exploring initiatives. It's a matter of personal growth and sharing - and yes, it can help you remain healthier.

Blog Catalog has teamed up with Refugees United to do exactly that.

Creating change in the world means making a conscious effort. It takes compassion and maturity to get involved in helping others. Today's effort is directed at helping refugees.

There are currently an estimated 14 million refugees worldwide. They come from all cultures, and they are our kin. There are many ways to help. Choose just one. We all have the ability to do something positive.

Refugees can't go home - they have no home. They'…

Once a month shot for type 2 diabetes in the works that is also cheap

Anyone diagnosed with type 2 diabetes know it isn’t easy to manage blood sugar control. One of the barriers is the constant need for monitoring blood sugar and giving injections in the morning and evening - and for some, even more often.
Now there is a drug in development that means one injection that could last for 14-days. The implication is more freedom from the burdensome act of carrying around insulin.
Biomedical engineers at Duke University have developed a  technology that could replace daily and even weekly insulin injections for type 2 diabetes treatment.
What if you only needed insulin once a month?
The insulin is combined with a biopolymer that  keeps insulin circulating in the body for a longer period of time than what is currently on the market. The development could mean insulin injections could be given just once or twice a month, which could be life-changing for those trying to manage type-2 diabetes.
Current therapies that target insulin signaling molecules only last a …
