Top 10 GMO Foods to Avoid

Top 10 GMO Foods to Avoid | Longevity science | Scoop.it

The FDA allows GMOs for food consumption, stating that no difference can be found between the GMO and non-GMO versions of foods such as corn and soybeans. However, the FDA does not require product labeling to identify this content.

 

It may interest you to know that many other countries have not yet approved these foods for the human market.

 

With issues ranging from reproductive failure to allergic reactions cited as potential outcomes of GMO consumption, the case may not be closed. Without proper labeling, it is hard to make an informed decision.

 

These are the top 10 GM foods that you may be consuming.

T Cells with Chimeric Antigen Receptors Have Potent Antitumor Effects

T Cells with Chimeric Antigen Receptors Have Potent Antitumor Effects | Longevity science | Scoop.it

Tumor immunotherapy with T lymphocytes, which can recognize and destroy malignant cells, has been limited by the ability to isolate and expand T cells restricted to tumor-associated antigens.

 

Chimeric antigen receptors (CARs) composed of antibody binding domains connected to domains that activate T cells could overcome tolerance by allowing T cells to respond to cell surface antigens; however, to date, lymphocytes engineered to express CARs have demonstrated minimal in vivo expansion and antitumor effects in clinical trials...

Same Kidney Transplanted Twice | Singularity Hub

Same Kidney Transplanted Twice | Singularity Hub | Longevity science | Scoop.it

Kidneys make up about 80 percent of transplanted organs. One kidney was transplanted into a young patient with a common disease called focal segmental glomerulosclerosis (FSGS). After transplant, the donor kidney started growing diseased.

 

But it wasn't the end of the line for that transplanted kidney. Something unusual occurred- the same kidney was transplanted into another patient and the disease was reversed.

Delaying Fat Cell Growth

Delaying Fat Cell Growth | Longevity science | Scoop.it

Researchers from Purdue University in Indiana are testing a compound found in red wine that has the ability to block the processes of fat cell development. The research into the compound known as piceatannol may lead towards finding a simple method to combat obesity.

 

Piceatannol results from the conversion of resveratrol – a compound found in red wine, grapes and peanuts that is also thought to combat cancer, heart disease and neurodegenerative diseases. When resveratrol is converted into the piceatannol

Gold nanostars deliver drugs directly to cancer cell nucleus

Gold nanostars deliver drugs directly to cancer cell nucleus | Longevity science | Scoop.it

While effective at killing cancer cells, chemotherapy is currently a shotgun approach that can also harm healthy cells and cause serious side effects in patients.

 

The ability to deliver drugs directly into cancer cells would provide a more targeted approach to more effectively treat the disease with lower doses of drugs and less side effects.

 

Researchers at Northwestern University are claiming to be the first to develop gold nanostars that provide a much more precise approach by delivering a drug directly to a cancer cell’s nucleus.

Plastic in Your Food… and in Your Body

Plastic in Your Food… and in Your Body | Longevity science | Scoop.it

A study found that a family who stopped eating foods that had been in contact with plastic experienced huge reductions in body levels of plastic toxins in just three days.

 

“Plastic food packaging is a major source of these potentially harmful chemicals, which most Americans harbor in their bodies. Other studies have shown phthalates (pronounced THAL-ates) passing into food from processing equipment and food-prep gloves, gaskets and seals on non-plastic containers, inks used on labels — which can permeate packaging — and even the plastic film used in agriculture.”
