Herbs and spices appear to take the center stage in American and European kitchens. They are known to enhance the flavor and the aroma of many delicacies and cuisines without the expense of adding more salt or sugar.

However, in our present generation, chefs and cooks are not the only ones who can rejoice with Mother Nature’s present of herbs and spices. Scientists and health and weight loss enthusiasts also have a reason to rejoice as well.

In a study published in the May 2011 issue of the British Journal of Nutrition, a group of scientists from New Jersey,  USA discovered that a special herb, the rosemary leaf, can also be useful to those who want to limit their weight gain and improve their blood sugar and cholesterol levels.

Rosemary leaves naturally contain lots and lots of antioxidants. This is the reason why many food supplement preparations have included rosemary in their ingredients. Rosemary also has an anti-inflammatory property that may exert some positive effect to the course of many chronic diseases such as cardiovascular problem and type 2 diabetes. Interestingly, it has been shown in this study that rosemary extract can also limit weight gain in laboratory mice fed constantly with a high fat diet.

However, even with all the buzz about the rosemary’s effect to these lab animals, more clinical trials involving human subjects are necessary to establish its safety and efficacy in the human population.
