Plant based diet study debunks eating for your blood type for weight loss, health

You may have read that it's important to eat certain foods based on your blood type. Depending on whether your blood type is O, A, B or AB, proponents of the blood type diet say there are foods to eat and foods to avoid for optimal health and a longer life.  Can eating certain foods based on blood type really help you live longer? The blood type diet was first introduced in 1996 by a naturopathic physician, Peter D'Adamo who alleges that even the spices you put on your food could contribute to better health and should be individualized for your specific blood type.  The theory is that certain foods and even the type of exercise you do should be individualized.  For instance, if you have type O blood you should eat plenty of meat and fish protein, vegetables and fruits but stay away from legumes - at least so the dietary guidelines say.  Recommendations for weight loss include avoiding dairy, corn and wheat and filling up on red meat, broccoli, spinach and olive oil.  Type A ind

Update: Hydroxychloroquine safety study retracted by major medical journal

In a new study from Brigham and Women’s hospital, nearly 16,000 patient outcomes were analyzed that were diagnosed with COVID-19 and received the drug hydroxychloroquine.

Instead of improving, patients were four times more likely to experience dangerous heart irregularity, compared to those not teated with the antimalarial drug.

Patients in the study that were given hydroxychloroquine were also more likely to die.

The study is recently published in the medical journal The Lancet  and is the most recent to address a hot topic about whether the medication, which is also prescribed to treat autoimmune disorders, should be  used to treat COVID-19.

Mandeep R. Mehra, a corresponding study author and executive director of the Brigham’s Center for Advanced Heart  Disease said the drug, or any regimen including a chloroquine,  did not help “no matter which way you examine the data.”

Patients from six continents included 

The researchers looked at data from 671 hospitals that included six continents and 96,000 patients who were in the hospital and diagnosed with COVID-19.

More than 15,000 out of the 96,000 patients were given the drug, with or without antibiotics; 10,698 patients taking the drug or a combination  died in the hospital.

Still no conclusions

So what does this study really mean? Not much - and the reason is because the analysis was observational. 

Until clinical trials are done the authors are being careful to say not much more than it shouldn't be used for COVID-19. There' still no 'hard-core' conclusions about whether or not hydroxychloroquine is safe or even effective for treating COVID-19.

Much of the controversy surrounding  the drug stems from the fact that it’s been around for many years and has been taken by patients; without any adverse effects. Additionally, there is no definitive treatment protocols for COVID-19, leaving clinicians grasping for treatments that just might help and make sense clinically,

A brand name for the drug is Plaquenil that is known to have antiviral properties. Some if it's uses include as a prevention for the malaria virus, treating rheumathoid arthritis, lupus and juvenile arthritis. 

According to the American Academy of  Rheumtology, how the drug works to treat autoimmune diseases isn't even known and heart rhythm problems are rare; usually when the hydroxychloroquin is combined with "other medications". 

More research is suggested to clarify the possibility that the antibiotic Azithromycin contributed to ventricular arrhythmias among the patient outcomes analyzed.

Can you eat square or heart shaped Japanese watermelon?

Is square or heart shaped watermelon tasty? Image Wikimedia Commons 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 , Hear

Health Benefits of Baby Broccoli for Preventing Stomach Cancer

According to new research, eating baby broccoli may help in the prevention of stomach cancer. The health benefits of broccoli come from the ability of an ingredient in baby broccoli to reduce colonization of H. Pylori bacteria in the gut. H. Pylori is common, affecting fifty percent of the world’s population. The newest and additional health benefit of broccoli for thwarting stomach cancer was found by researchers in Japan. Eating two and a half ounces of baby broccoli daily for two months provided health benefits because the compound sulforaphane, found in high amounts in baby broccoli, reduced the amount of H. Pylori in the gut. The researchers measured HpSA, a component of H. Pylori, to find that fifty people fed two and a half ounces of baby broccoli for two months had a forty percent reduction in the harmful gut bacteria. The researchers say the health benefits of baby broccoli… “might potentially have an effect on the cause of a lot of gastric problems…” The newly discovered h

Five crazy fast facts for coffee lovers

It’s no secret that most of us love our coffee. The internet is loaded with funny memes about our morning cup of Java that are widely shared; for good reason. Here are five crazy fast facts about coffee that most people never knew.  Coffee is good for digestion (we knew that), but it seems to stimulate the bowels in ways unknown. Researchers have found that even without the caffeine, a cup of brew stimulated muscle movement in the intestine in rat studies.  It seems the researchers were interested in finding a simple way to help patients who have had surgery. Having a bowel movement after surgery is sometimes difficult and can lead to complications and prolonged hospital stays from paralytic ileus.  Scientists were able to discover that coffee lowers bacteria counts in the gut in addition to their finding that the morning brew stimulates intestinal contraction, regardless of the caffeine content in the coffee.  Those findings were presented last year at Digestive Week ®  "When rat
