Cumin

Also called comino , this ancient spice dates back to the Old Testament.

Shaped like a caraway seed, cumin is the dried fruit of a plant in the parsley family. Its aromatic, nutty−flavored seeds come in three colors: amber (the most widely available), white and black (both found in Asian markets). White cumin seed is interchangeable with amber, but the black seed has a more complex, peppery flavor. Cumin is available in seed and ground forms. As with all seeds, herbs and spices, it should be stored in a cool, dark place for no more than 6 months. Cumin is particularly popular in Middle Eastern, Asian and Mediterranean cooking. Among other things, it's used to make curries, chili powders and Kummel Liqueur.

 Using cumin may help decrease blood sugar levels for people. A study published in "Food and Chemical Toxicology" in 2010 compared the blood sugar levels for mice taking a popular diabetes medication to mice taking cumin. The results showed the medication and the cumin significantly reduced blood sugar levels in the mice.

Ground cumin may help prevent cancerous tumors. A study published in "Cancer Letters" in 2007 involving mice showed cumin to help protect against the induction of colon cancer. Preclinical studies showed cumin to help prevent the growth of stomach tumors and liver tumors in mice, according to the same study. The spice may help reduce the likelihood of cancer by reducing free radicals and increasing the liver’s ability to detoxify the blood.

Historically, people used cumin to treat epilepsy, toothaches and diarrhea, increase urination and reduce inflammation in the body. Cumin may help stimulate the pancreas to secrete enzymes to assist with proper digestion, according to Drugs.com. Using fresh seasonings, including ground cumin, can help spice up food. People on a restricted diet can add flavor using this spice without increasing sodium or fat intake.
