Palm oil is widely used in the food industry for its chemical/physical properties, low cost and wide availability. Its widespread use has provoked an intense debate about whether it is a potential danger to human health. In a careful review of the scientific literature, we focused on nutritional characteristics and health effects of the use of palm oil with regards to children, seeking to determine whether there is evidence that justifies fears about the health effects of palm oil. Our review showed that palm oil represents a significant source of saturated fatty acids, to which scientific evidence attributes negative health effects when used in excess, especially with regards to cardiovascular diseases. However, to date, there is no evidence about the harmful effects of palm oil on the health of children. Nevertheless, palm oil has possible ill health effects linked to its composition of fatty acids: its consumption is not correlated to risk factors for cardiovascular diseases in young people with a normal weight and cholesterol level; the elderly and patients with dyslipidaemia or previous cardiovascular events or hypertension are at a greater risk. Therefore, the matter is not palm oil itself but the fatty-acid-rich food group to which it belongs. The most important thing is to consume no more than 10% of saturated fatty acids, regardless of their origin and regardless of one's age. Correct information based on a careful analysis of the scientific evidence, rather than a focus on a singular presumed culprit substance, should encourage better lifestyles.
棕榈油因其化学/物理特性、低成本和广泛可用性而在食品工业中被广泛使用。其广泛的使用引发了一场激烈的争论,即它是否对人类健康构成潜在威胁。在对科学文献进行仔细审查时,我们专注于棕榈油的营养特性和对儿童的健康影响,试图确定是否有证据证明对棕榈油健康影响的担忧是合理的。我们的综述表明,棕榈油代表了饱和脂肪酸的重要来源,科学证据表明,过量使用饱和脂肪酸会对健康产生负面影响,尤其是对心血管疾病。然而,迄今为止,尚无关于棕榈油对儿童健康有害影响的证据。然而,棕榈油可能因其脂肪酸组成而对健康产生不良影响:其消费与年轻人的心血管疾病风险因素无关,这些年轻人的体重和胆固醇水平正常;老年人、血脂异常或有先前心血管事件或高血压的患者风险更大。因此,问题不在于棕榈油本身,而在于它所属的富含脂肪酸的食物组。最重要的是,无论其来源如何,无论年龄大小,饱和脂肪酸的摄入量都不应超过 10%。基于对科学证据的仔细分析的正确信息,而不是专注于单一的假定罪魁祸首物质,应该鼓励更好的生活方式。
