3 Long-Term Effects Of Soybean Oil Consumption

Soybean oil has become a household staple in every kitchen around the world and is touted as cheap, versatile, and convenient to use. The oil is produced from the seeds of the soybean plant, which contain polyunsaturated fats in high concentrations, mainly from omega-6 fatty acids that have been tauted as beneficial to heart health. However, as time progresses, new questions are asked regarding soy's long-term health benefits.

According to Dr. Varun Bansal, a cardiologist at Apollo Hospitals, "Soybean oil in moderation will do some good because of the omega-6 fatty acids. High intake has been associated with inflammation, heart diseases, and metabolic disorders."

Here are three major long-term impacts of soybean oil consumption and what it portends for your health.

1. Impact on Heart Health

Soybean oil has a very high omega-6 content. While balancing omega-6 fatty acids with some amount of omega-3 fatty acids could help lower LDL or "bad" cholesterol levels, too much of the former leads to an imbalance in the vital ratio.

He emphasizes, "There is evidence to show that excessive amounts of omega-6 fatty acids can increase inflammation in the body. Over time, this inflammatory state eventually contributes to atherosclerotic plaque formation - two of the major culprits behind heart attacks and strokes.

Research further indicates that soybean oil, aside from its potential inflammatory effects, may not meaningfully increase high-density lipoproteins or lower triglycerides; it is therefore less capable of benefiting cardiovascular health in its totality. The nature of diets that have overdependence on soybean oil results in imbalance between omega-6 and omega-3 fatty acids. This calls for intake of oils with better nutritional profile.

2. Risk Factors for Fatty Liver Disease and Metabolic Conditions

One of the major long-term side effects of excessive soybean oil consumption is that it has the potential to make non-alcoholic fatty liver disease worse. NAFLD is the condition where fat in the liver increases, a problem increasingly common worldwide, related to diet and lifestyle.

As Dr. Bansal warns, "NAFLD is not just a liver issue; it increases the risk of cardiovascular disease." According to studies, soybean oil can also induce obesity and insulin resistance-the two principal causes of metabolic disorders.

The JAMA publishes one study, showing the possible fat deposition induced by soybean oil into the body. More precisely, the soybean oil makes fats settle near the liver, thereby leading to its expansion. Such effect of oil further exacerbates with increasing resistance towards insulin. Gradually, this could also open up doors to type 2 diabetes.

3. Hormonal and Cognitive Issues

Soybean oil contains phytoestrogens, estrogen-like compounds found in plant-based foods. Although there is much hype about the abilities of these compounds to balance one's hormones, excessive use can have unintended effects on the body. According to Dr. Bansal, "Phytoestrogens in soybean oil may disrupt hormonal balance in sensitive individuals, especially those subjected to estrogen fluctuations. This over time may affect reproductive health and growth patterns and even cognitive function in some cases."

The Honolulu-Asia Aging Study (HAAS) caused quite a stir when it revealed that higher soy intake was associated with cognitive decline in men. The study indicated that midlife tofu intake, a surrogate for soy-based foods, was linked to brain atrophy and later-life cognitive decline. It was hypothesized that soy isoflavones might act as estrogen receptor antagonists, thus potentially impairing brain health.

Though human studies on this topic remain limited, animal studies have suggested that high levels of phytoestrogens could have a range of negative effects, including impaired reproductive health and altered brain development.

Alternatives to Opt

While soybean oil still finds its way into cooking, these results highlight that it is best used in moderation. According to Dr. Bansal, "Rather than relying on one source of oil, diversify your diet with oils offering a better balance of omega-3 and omega-6 fatty acids, such as flaxseed oil or olive oil."

Other than the diversity, a balanced diet which is constituted with whole foods, exercise regularly and healthy eating behaviors may counteract some risks linked with soybean oil intake.

Soybean oil, one of the popular saturated fat replacements, has its positive as well as negative side effects. With the rich amount of omega-6, it could have an effective support towards heart conditions when consumed in minimal quantities; however, its overconsumption causes inflammation, hormonal imbalances, and metabolic disorders.

Like all other food choices, a moderate balance is key. The danger to soybean oil is minimized by replacing healthier fats in it and by taking soybean oil in moderate amounts. According to the concluding words of Dr. Bansal, "Moderation and variety make for a healthy diet. No single food item and no single ingredient should own the plate.
