The mere scent of olive-oil may be good for your health, according to a recent study conducted by the German Research Center for Food Chemistry.

The researchers caution that the study was small and preliminary. Okay, but dig this: just imparting the scent of olive oil to food — in the case of this study, plain yogurt — reduced the number of calories consumed by test participants, and improved their blood-sugar response.

One of the key components in the olive oil aroma used in the study was hexanal, which smells like freshly cut grass.

So the benefits of the famously healthy Mediterranean Diet may be yours simply by breathing, and suggests even greater potential for essential oils and aromatherapy as keys to well-being.
