A Little Dressing Added to Salad, Makes It Healthier

JAKARTA, NETRALNEWS.COM – Are you a fan of salad? Be careful with the oils in the mixture as too much oil is considered bad for your health. 

However a new study shows that adding a little dressing to your salad can increase its benefits.

According to the research, fat from soybean oil increases the absorption of eight different micronutrients in vegetables.

Better absorption of nutrients promotes health benefits, including cancer prevention and eyesight preservation, researchers said.

The study, published in the American Journal of Clinical Nutrition, noted that eating the same salad without additional oil reduces the possibility of the body absorbing nutrients.

Researchers at Iowa State University in the US, as reported by Boldsky, Wednesday (10/11/2017), found that added oil helps the absorption of seven different micronutrients in salad vegetables. These nutrients include four carotenoids - alpha and beta carotene, lutein and lycopene - two forms of vitamin E and vitamin K.

The oil also promotes the absorption of vitamin A, the eighth micro nutrients tracked in the study, which formed in the intestines from alpha and beta carotene.

The study was based on previous research focusing on alpha and beta carotene and lycopene. Better absorption of nutrients promotes health benefits, including cancer prevention and eyesight preservation, said Wendy White, an associate professor of food science and human nutrition at Iowa State University.

According to White, the best way to explain it would be to say that adding twice the amount of salad dressing leads to twice the absorption of nutrients.

Researchers have considered 12 college-age women who consumed salads with varying levels of soybean oil, the usual ingredients in commercial salad dressings. The subjects then had their blood test to measure the absorption of nutrients.

Women were selected for the trial because of differences in speed of men and women metabolizing the nutrients in question. The results showed that maximum nutrient absorption occurred in about 32 grammes of oil, which was the highest amount studied, or slightly more than two tablespoons.

However, White said she found some variability among the subjects. "For most people, this oil will benefit the absorption of nutrients. The average trend, which is statistically significant, is to improve absorption," said White.
