I often add 3-4 shakes of sesame chili oil to my salads. It probably equates to 1/4 teaspoon. Never use it in large quantities, and NEVER cook with it. Only add to food after it's been cooked. It's actually loaded with antioxidants and small amounts are very healthy. Large quantities would be a disaster, especially heated as it will oxidize rapidly.
There is no excuse to ever, EVER eat soybean or sunflower oil. They're both horrendous for your health AND tasteless, so there's not a single upside.
Don't put your trust in anyone on this forum, including me. You are the key to your own success.
