Coffee triumphs over the negative effects of obesogenic diets

Do you like a cup of coffee? While many people relate coffee to insomnia due to caffeine, a new study proves otherwise. A study, published in the Journal of Functional Foods and conducted by the University of Illinois (UI) last week, revealed another profound benefit of having coffee, related to a slimmer body.

Coffee helps fight the negative effects of obesogenic diets by reducing the storage of lipids in fat cells and limiting weight gain and the production of triglycerides.

The study, requiring four weeks to complete, tested on lab rats. The scheduled diet for these lab rats was 40 percent fat, 45 percent carbohydrate, and 15 percent protein. Together with the diet, the lab rats also consumed caffeine equivalent to a human intake of four cups of coffee daily.

Then, the UI researchers conducted cell studies on the lab rats, exposing their adipose cells to synthetic caffeine from coffee and mate tea extracts. From the cell studies, the researchers found that regardless of the source, caffeine halted the accumulation of lipids in adipose cells by 20 – 40 percent.

Not only the adipose cells, but the researchers also conducted studies on genes associated with obesity and metabolism such as fatty acid synthase gene (FASN) and the lipoprotein lipase gene (LpL). FASN is responsible for the synthesis of fatty acids from glucose, while LpL for generating enzymes to break down triglycerides.

With synthetic caffeine treatment, the FASN expression reduced by as much as 31 – 39 percent, while LpL by 51 to 69 percent.

A famous tea in Latin America, mate tea is rich in phytochemicals, flavonoids, and amino. Moreover, mate tea consists of 65 – 130mg of caffeine in one serving, compared to coffee with 30-300 milligrams of caffeine in one hot serving.
