Scientists have found that palm oil reduces the effectiveness of certain types of antibiotics.<\/span><\/span>\u00a0<\/span><\/h2>\r\n

Resistance of microorganisms to antibiotics is one of the biggest scares of the 21st century. Their growing resistance is a completely natural phenomenon, but it is also accelerated by the frequent and excessive use of antibiotics. One way to get rid of resistant bacteria is to use a combination of multiple drugs. However, combination treatment often brings with it a range of unwanted side effects. These can also occur when drugs are combined with different foods or nutritional supplements, which often reduce the effectiveness of the drugs. A very well-known example is grapefruit and grapefruit juice. The latter inhibits the activity of certain enzymes (CYP3A4) in the intestines and, due to their lack of activity, a much higher amount of active substances from medicines are then absorbed into the body. These can subsequently cause cardiovascular problems and other risks. Some fatty acids also interact with food in a similar way, and it is these that the research team focused on this time.\u00a0<\/p>\r\n

One of the most prominent bacteria that is considered a serious global threat due to its increasing resistance is Staphylococcus aureus.\u00a0<\/p>\r\n<\/div>\r\n<\/div>\r\n

\r\n
Growth curves of Staphylococcus aureus strains upon different concentrations of hydrolyzed palm oils or lauric acid ((A)-Astrocaryum vulgare oil; (B)-Cocos nucifera oil; (C)-Elaeis guineensis oil; (D)-lauric acid) determined spectrophotometrically. SA Staphylococcus aureus, OD optical density.<\/div>\r\n<\/div>\r\n

\r\n

Using an in vitro checkerboard method, the researchers tested interactions between oxacillin (a beta-lactam antibiotic of the penicillin class) and palm oils from the tucuma palm (Astrocaryum vulgare), coconut tree (Cocos nucifera) and oil palm (Elaeis guineensis) against nine strains of S. aureus. Since lauric acid was identified as the main component of all the oils by gas chromatography, the researchers also tested its interactions in combination with oxacillin.\u00a0<\/p>\r\n

The results showed strong antagonistic interactions between palm oils and oxacillin. Similar effects were subsequently induced by the aforementioned lauric acid. Thus, all indications are that the combination of oxacillin with palm oils and their constituents may negatively affect the treatment of staphylococcal infections in humans (and animals). This is true both in the case of topical application of the oils (to the skin surface) and in the case of high lipid diets. And what can you actually come across palm oils in? Unfortunately, due to their low price, they can be found in most products nowadays, especially in chocolates, biscuits, margarines and savoury snacks.\u00a0\u00a0<\/p>\r\n
