Introduction
Sesame oil is primarily composed of fats. When used in small amounts as a seasoning in daily cooking, it enhances the flavor of food. The unsaturated fatty acids it contains can be normally metabolized by the body, posing no adverse health effects and even helping to improve appetite, thus meeting regular dietary needs. However, consuming large quantities of sesame oil at once or excessive long-term intake may lead to excessive fat and calorie levels in the body.
Under normal circumstances, moderate consumption of sesame oil can enhance flavor and aroma without significant side effects. However, excessive intake may lead to gastrointestinal discomfort and related issues. If in doubt, it is advisable to consult a healthcare professional in advance. Detailed analysis is as follows:
Sesame oil primarily consists of fats. When used in small amounts as a seasoning in daily cooking—such as in salads or added to soups—it enriches the taste of food. The unsaturated fatty acids it contains can be normally metabolized by the body, posing no adverse health effects, while also helping to stimulate appetite, thus meeting everyday dietary needs.
Consuming large amounts of sesame oil at once or over-consuming it over a prolonged period may result in excessive fat and calorie intake. Excess fat increases the digestive burden on the gastrointestinal tract and may cause discomfort such as bloating, diarrhea, and nausea. Long-term overconsumption may also lead to weight gain and increase the risk of metabolic disorders such as hyperlipidemia and fatty liver disease.
It is important to control the amount of sesame oil used in daily cooking and avoid drinking it directly in large quantities. It is recommended to use sesame oil as a seasoning incorporated into regular meals rather than consuming it alone.
