What's New and Beneficial About Garlic
- One potential health benefit from garlic might be obtained by chopping or crushing it and letting it sit before heating it along with other recipe ingredients. Chopping will activate alliinase enzymes in some of the cells, and sitting will allow those enzymes to convert some of the garlic's allin into allicin. Both alliin and allicin are sulfur-compounds and while both provide health benefits, the health benefits of allicin are especially well-documented in research studies.
- Garlic may help improve your iron metabolism. That's because the diallyl sulfides in garlic can help increase production of a protein called ferroportin. (Ferroportin is a protein that runs across the cell membrane, and it forms a passageway that allows stored iron to leave the cells and become available where it is needed.)
- In addition to being a good source of selenium, garlic may be a more reliable source as well. Garlic is what scientists call a "seleniferous" plant: it can uptake selenium from the soil even when soil concentrations do not favor this uptake.
- The cardioprotective benefits of garlic may partly rest on the production of hydrogen sulfide (H2S) gas. Our red blood cells can take some types of sulfur-containing molecules in garlic (called polysulfides) and use them to produce H2S. This H2S in turn can help our blood vessels expand and keep our blood pressure in check. Interestingly, some processed garlic extracts cannot be used by our red blood cells in the same way and do not seem to provide the same level of cardioprotection that is provided by garlic in food form.
- While still in its very early stages, research suggests that garlic consumption may actually help to regulate the number of fat cells that get formed in our body. 1,2-DT (1,2-vinyldithiin) is one of the unique sulfur compounds in garlic that has long been recognized as having anti-inflammatory properties. But only recently have researchers discovered that some of our fibroblastic cells (called "preadipocytes") only evolve into full-fledged fat cells (called "adipocytes") under certain metabolic circumstances involving inflammatory system activity. 1,2-DT may be able to inhibit this conversion process. Since obesity is increasingly viewed by researchers as a chronic state of low-grade inflammation, the inflammation-related benefits of garlic's 1,2-DT may eventually be extended into the clinical area of obesity.
