The study that was presented at the American Chemical Society Annual Meeting in Atlanta, highlighted the ability of grape seed extract in lowering blood pressure, the ability of Chives in protecting against salmonella and other illnesses that are food-borne, and the ability of pine nut oil in suppressing appetite.
The lead researcher, Salam A. Ibrahim, Department of Food Science and Nutrition, North Carolina, noted that although most herb, plant and mushroom extracts show antimicrobial properties, chives seem to have the most potent effect against 38 strains of salmonella, the common bacterial food-borne illness. The lab tests revealed that the chives extract, when taken in sufficient quantities, inhibits salmonella activity, without the need for additional irradiation or chemical preservatives. However, when heated to a temperature above 121 deg. Cel. for fifteen minutes or more, the antibacterial activities were completely lost.
Hence, adding chives to everyday food should be considered a healthy alternative, concluded Ibrahim.
Another study, conducted by Dr. G. Tissa Kappagoda, Department of Internal Medicine, California University, revealed that Grape seed extract when administered to 24 patients with metabolic syndrome, patients who consumed about 150 to 300mg of grape seed extract per day, showed considerable drop in their blood pressure, while those under placebo did not show any change.
Dr. Kappagoda concluded that grape seed extract could be a potential tool for pre-hypertensive people, and could be included as a part of lifestyle management routine along with exercise and weight management.
Finally, a study on Korean Pine nuts and their association with weight loss, led by Jennifer L. Causey, Lipid Nutrition Company, revealed that nuts contain an oil called Pinolenic acid that stimulates the release of two appetite-suppressing hormones, CCK and GLP1. The study conducted on 18 obese women, who consumed 3gms of Pinolenic acid in gel capsule form, showed an increase in appetite suppressing hormone levels, and the appetite of women, fell by one-third.
Causey concluded that these fatty acids give a feeling of fullness, and could prove beneficial, as part of a weight-loss program which also includes diet and exercise, while there is the scientific evidence for the satiety effect. However, more studies are required in the works.
