In recent years, flaxseed oil and sesame oil have been attracting attention as they can supplement the nutritional deficiencies in modern diets. Both flaxseed oil and sesame oil are said to have anti-aging effects in addition to their health benefits. We will explain flaxseed oil and sesame oil, which many people are interested in, compare their characteristics and effects, and handle precautions.

Flaxseed oil and sesame oil

When considering a healthy diet, many people will want to reduce oil. There is a lot of information on the media and the Internet that conveys ideas for reducing oil, such as "non-fried foods" that can be made with less oil and the use of fluorinated cooking utensils. However, flaxseed oil and sesame oil, which are attracting attention, are not reduced, but are expected to have health benefits by incorporating them. Let's explain the features of each.

What is flaxseed oil?

Flaxseed oil (flaxseed oil) is an oil extracted from the seeds of a plant called "flax", an annual plant of the flax family, which is a raw material for high-grade linen. Also known as linseed oil.

To turn flat brown flax seeds into oil, first carefully extract the flax seeds using the "cold press method". Cold pressing is a method of extracting oil by applying pressure without applying heat. The cold pressing method is important because the fatty acids in the seeds are transformed into harmful trans fatty acids when the oil is extracted at high temperature. After that, it is divided into two types of linseed oil: refined linseed oil, which is deoxidized and deodorized after pressing, and unrefined linseed oil, which is not refined.

Unrefined flaxseed oil is the most squeezed oil. Since it is not refined, the color is dark yellow and the astringency remains, but the biggest merit is that the original nutrition of flaxseed oil remains.

What is sesame oil?

Sesame oil is an oil extracted from the seeds of a plant called "Egoma", an annual plant of the Labiatae family. Also called perilla oil, or perilla oil. Some people think that it is a member of sesame from the name, but it has nothing to do with sesame.

Perilla frutescens is considered to be the oldest oil and fat plant in Japan, and traces of cultivated perilla have been found in several archaeological sites 10,000 to 5,500 years ago. The custom of eating perilla leaves as a traditional food still remains in parts of Fukushima, Iwate, Miyagi and Gifu prefectures. It is sometimes called "Junen" because of the tradition that if you eat perilla, you will live 10 years longer.

Like flaxseed oil, perilla seeds are extracted by cold pressing to become oil. In addition, it is the same as flaxseed oil in that there are two types, unrefined and refined. Sesame oil is only called shiso oil and has a slight perilla flavor.

In order to avoid oxidation, which is "deterioration of oil", try to avoid exposure to air and light, which are the causes of oxidation.

For that purpose, it is recommended to purchase one with a small single-use size. Before opening, keep it in a cool and dark place, and once opened, seal it and store it in the refrigerator. Use up the opened flaxseed oil in about a month. In addition, it is sensitive to heat, so you can maximize the effect without destroying the nutritional components by eating it raw as if it were dressing without heating.

It is also important to pay attention to your intake. Even though it is good for your health, flaxseed oil is still an oil. A teaspoon has about 40 calories, so avoid taking too much. The recommended daily intake of flaxseed oil is about 1 teaspoon = 4g per day. For children, use about 3g, and for infants, use about 2g.
