Spices have many health benefits beyond their ability to add flavor to foods as an alternative to the excessive amounts of fat, sugar, and salt so common in the American diet.
Dr. Ward Dean and I wrote an article for the online Vitamin Research Products library on the anti-oxidant, anti-microbial, and anti-inflammatory effects of common spices. I found a wealth of information in the medical literature about spices.
My favorite was the article by P. W. Sherman and G. A. Hash from Cornell University, Ithaca, New York, on the analysis of recipes in 107 traditional cookbooks from 36 countries. Sherman and Hash found that spice use increased with increasing climate temperature, especially for meat dishes.
The authors noted that meat is more susceptible than vegetables to attack by bacteria and fungi, and suggested that the recipes for meat in warm climates included the most spices in order to keep them safe for human consumption.
Rosemary is one of the spices that has also demonstrated anti-cancer effects. Dr. Chiung-Huei Peng and colleagues in Taiwan analyzed supercritical fluid carbon dioxide extracts of rosemary.
The primary active components were found to be carnosic acid, carnosol, rosemarinic acid, and ursolic acid. The extract inhibited growth of liver cancer cells in lab cultures, without killing normal liver cells. The suggested mechanism was the anti-inflammatory effects of these compounds.
“In chronic inflammation, cytokines induce production of nitric oxide (NO), which is converted to DNA-damaging, carcinogenic peroxynitrite and nitrite,” Peng explained. The rosemary extract inhibited production of nitric acid without cellular toxicity.
As a bonus, Dr. T. Harach and colleagues at the Nestle Research Center in Switzerland reported that rosemary limited weight gain in mice fed a high-fat diet.
Mice who received rosemary leaf extract at a daily dose of 200 mg/kg of body weight also showed a decrease of 39 percent in liver triglyceride levels, indicating protection from fatty liver disease.
Rosemary is available in most grocery stores and has been used safely for thousands of years. The Food.com online kitchen dictionary recommends rosemary for dishes with beans, chicken, fish, lamb, pork, beef, grains, onions, oranges, peas, and spinach.

Hi, Here are some of the best things I know that fights cancer. My family and I have them alot. One of the best is ground turmeric. It is the best and number one poweful fighter that kills cancer cells. They come as powder, tablet and tea. The other is pomegranate juice which is also great to fight cancer cells. Having plenty of fish as part of your diet is also great and Cod liver oil is also much healthier than fish oil. Cod liver is much better than fish oil. All these are the best in fighting cancer. Not only they fight cancer but they are very healthy as well.
