Sunflower oil is one of the most commonly found oils across the world. Consumers prefer the clear appearance of sunflower oil, the high smoke point of this oil, and the taste that does not clash with spices. However, excess intake of this product may cause certain problems. Knowing the actual side effects of sunflower oil will help you make the right choice for your daily diet.
Although the moderate consumption of this product provides you with dietary Vitamin E, today's diets have serious problems with overconsumption. The majority of processed food products contain refined seed oils. Knowing how to use sunflower oil properly will save your heart, digestive system, and metabolism. Let’s check what happens when you overconsume this popular kitchen oil.
Why Does Overusing Sunflower Oil Cause Health Problems?
Sunflower oil consists mainly of polyunsaturated fats, primarily Omega-6 linoleic acid. Though Omega-6 fatty acids are vital for the body, they must be consumed in a balanced manner with Omega-3 Fatty Acids.
Previously, humans ensured that their Omega-6 to Omega-3 ratio was around 1:1 or 2:1. In today’s world, with frequent consumption of seed oils, the ratio can go up to 20:1. Such a tremendous imbalance causes constant pressure on your body’s regulatory system.
- High Levels of Omega-6 Linoleic Acid: Leads to the production of inflammatory compounds inside the tissue.
- Vulnerability of the Molecule: Polyunsaturated Fats are easily oxidized when exposed to heat.
- Manufacturing and Solvent Extraction: The processing removes the antioxidants from the oil which come naturally in the bottled oil.
- Calorie content: Just like any other fat used for cooking, it has 120 calories per tablespoon.
What Are the Major Side Effects of Sunflower Oil Overuse?
