Refined Soya Oil – Health Risks for Older Adults and Their Metabolism

A recent study conducted by researchers at the University of California has highlighted the risks that refined soybean oil may pose to the health of older adults. Although this oil was previously considered beneficial due to its high polyunsaturated fatty acid content and low levels of saturated fat, new findings suggest it may have harmful effects on the body.

The researchers identified that refined soybean oil produces compounds called oxylipins, which accumulate in the body and can have damaging effects on metabolism. These substances can cause inflammation of the internal organs and promote fat storage, including cholesterol build-up — factors of particular importance to cardiovascular health in older adults.

The primary concern is not cold-pressed soybean oil obtained from organic crops, but rather the refined and ultra-processed variety. This type of oil is treated at very high temperatures to make it more fluid and to achieve its familiar golden appearance — and it is this process that generates the harmful compounds.

Presence in everyday foods

Refined soybean oil is found in numerous food products that older adults frequently consume: sauces, margarines, biscuits, pastries, tinned goods, dressings, and various types of snacks. This widespread presence means that exposure to these compounds is likely far greater than one might initially assume.

Laboratory animal studies have shown that subjects fed products containing soybean oil began to gain weight within just a few days. While further research is needed to confirm the effects in humans, the preliminary results are concerning — particularly for older adults who already have a slower metabolism.

Recommendations for older adults

Nutrition specialists recommend that older adults pay close attention to food labels and limit their consumption of products containing refined soybean oil. It is important for seniors to opt for healthier alternatives, such as extra virgin olive oil or other unsaturated oils obtained through natural methods.

Given that the metabolism of older adults is more vulnerable, and that many of the health complications affecting seniors are linked to chronic inflammation and cardiovascular problems, avoiding or reducing consumption of ultra-processed soybean oil can be an important preventive measure in maintaining optimal health.
