GE Crops and Unsustainable Agricultural Practices are Destroying our Planet’s Soil and Food Supply

Story at-a-glance

  • Genetically engineered crops and food products pose a threat to your health, resistance to disease, soil, and the global food supply
  • GE seed wars in India have resulted in a group of Indian scientists being found guilty of infecting and hiding the fact that indigenously created Bt cotton contained a Monsanto gene in a rush to get the seed to market Continue reading

Bee Pollen: One of the World’s Most Perfect Super Foods

One of the most unique substances on the planet, bee pollen, probably doesn’t get the recognition it deserves. This super food possesses all of the nutrients essential to sustain human life, with a breakdown of 55 percent carbohydrates, 35 percent protein, three percent vitamins and minerals, two percent fatty acids and five percent other substances.

Big Food’s 9 dirty Secrets You Should Know About

Last year, Big Ag and the food industry in general had successfully lobbied legislation in some states to prohibit undercover photos and videos from being taken of factory farming livestock scenarios and disallowed mainstream media outlets from receiving and displaying those photos or videos.

Salmonella in Pets and Humans

On April 6, 2012, the United States Food and Drug Administration announced a voluntary recall of Diamond Naturals Lamb Meal and Rice dry dog food. Since the initial recall, several other brands of food manufactured in a South Carolina plant have been voluntarily recalled for possible Salmonella contamination. Voluntary recalls of pet food are not uncommon, Continue reading

Oregano Delivers More Antioxidants than Blueberries, Oranges or Apples

Oregano, a common ingredient in Italian and Mexican cuisine, comes from the leaves of an herb native to the Mediterranean (not to be confused with Mexican oregano, native to the Americas), is one of the most concentrated antioxidant sources ever studied. According to data from the U.S. Department of Agriculture, its antioxidant activity is between three and 20 times higher than that of any other herb. Even well-known antioxidant-containing fruits fail to measure up: Oregano has four times the antioxidant activity of blueberries, 12 times that of oranges and 42 times that of apples.

While you can get some of these benefits from just cooking regularly with oregano, Continue reading

U of Minnesota Researchers Discover a Natural Food Preservative that Kills Food-Borne Bacteria

University of Minnesota researchers have discovered and received a patent for a naturally occurring lantibiotic — a peptide produced by a harmless bacteria — that could be added to food to kill harmful bacteria like salmonella, E. coli and listeria.

The U of M lantibiotic is the first natural preservative found to kill gram-negative bacteria, typically the harmful kind. “It’s aimed at protecting foods from a broad range of bugs that cause disease,” said Dan O’Sullivan, a professor of food science and nutrition in the university’s College of Food, Agricultural and Natural Resource Sciences. “Of the natural preservatives, it has a broader umbrella of bugs that it can protect against.”

The lantibiotic could be used  Continue reading

How Salmonella can be Used To Kill Tumors

How Salmonella can be Used To Kill Tumors

BRAUNSCHWEIG –  German scientists have shown how the bacteria migrate into tumors. Sara Bartels and Siegfried Weiss, of the Helmholtz Centre for Infection Research (HZI) in Braunschweig, say that a messenger substance from the immune system makes blood vessels in the cancerous tissue permeable, and thereby enables the bacteria to conquer and destroy the tumour.

The researchers add that, simultaneously, blood streams from the vessels into the cancerous tissue, a so-called necrosis develops, and the tumor dies.

“This influx of blood was the starting point for our investigations. There is an immunological messenger present during bacterial elicited inflammation that causes this kind of reaction. We searched for it – and found it,” says Siegfried Weiss, Head of the Molecular Immunology group at the HZI.

The researchers have revealed that this messenger is named after its role in the immune system: tumor necrosis factor, TNF-alpha for short.

They say that immune cells produce TNF-alpha when recognizing salmonella, thus alarming other immune cells.

According to them, a small amount of TNF-alpha is subsequently enough to dissolve the walls of the blood vessels in the tumor and allow the blood to stream into the cancerous tissue.

They hope to be able to modify salmonella so that they can migrate specifically into tumors and cause them to die.

Since salmonella can live even in tissues that are badly supplied with blood, the researchers believe that they can be used in tumor therapy.

This is interesting because chemotherapeutics cannot be transported to an area where there is no blood flow, and even radiation therapy requires oxygen for its reactions in the tissue.

“We have obtained an important indication of how bacteria migrate into tumors. We can now try to manipulate these bacteria to use them in cancer therapy without causing deadly infections,” says Sara Bartels.

“We need to find the right amount of bacteria aggressiveness, allowing the tumor to be colonized and destroyed without harming the patient,” she adds.

If the scientists succeed in accomplishing this feat, they may be able to take the next step forward: using salmonella to release therapeutic substances within the tumor and thus participate in its destruction.

“Our experiments are currently limited to absolutely basic research and experiments with laboratory mice. It may take years before this method is usable for human patients,” says Siegfried Weiss

The study has been published in the scientific journal PLoS ONE.
