We reviewed the scientific literature on the evidence of the relationship between palm oil and adverse effects on human health. Few studies have investigated the effects of palm oil per se, and the main reason why it has been associated with negative health effects is the relatively high content of saturated fatty acids (SFAs), particularly palmitic acid, which in turn have been associated with increased risk of coronary heart disease and some tumours. However, more recent investigations on the topic seem to have reconsidered the negative role of the dietary SFAs as a risk factor for cardiovascular diseases and show that not only the type of fat, but also that the triglyceride structure plays a role in cholesterolaemia. As regards to a role in cancer, specific studies on dietary palmitic acid or palm oil and the risk of cancer development are scanty, and the evidence is not convincing.

The initial burst release is a major obstacle to the development of microsphere-formulated drug products.
To investigate the influence of palmitic acid on the characteristics and release profiles of rotigotine-loaded poly(d,l-lactide-co-glycolide) microspheres.
MATERIALS AND METHODS:
Rotigotine-loaded microspheres (RMS) were prepared using the oil-in-water emulsion solvent evaporation technique. The in vitro characteristics of the RMS were evaluated with scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and a particle size analyzer. The in vitro drug release and in vivo pharmacokinetics of the RMS were investigated.
RESULTS AND DISCUSSION:
The SEM results showed that the addition of palmitic acid changed the surface morphology of the microspheres from smooth to dimpled and then to non-smooth as the palmitic acid content increased. DSC revealed the existence of molecularly dispersed forms of palmitic acid in the microspheres. The in vitro and in vivo release profiles indicated that the addition of 5% and 8% palmitic acid significantly decreased the burst release of rotigotine from the microspheres, and the late-stage release was delayed as the palmitic acid content increased across the investigated range (5-15%).
The addition of palmitic acid to the microspheres significantly affects the release profile of rotigotine from RMS.
