Agar Diet is a hot topic in Japan. Agar is an ingredient like gelatin, but it is very good for your health and diet. Let’s find out!
Agar Diet And Health Benefits
Agar is classified as a sea vegetable. It contains the highest amount of dietary fiber among any food categories. It has over 70g of dietary fiber per 100g.
Furthermore, agar has both soluble and insoluble dietary fiber. That is not all! Agar is rich in minerals. Below is the notable list of health benefits.
- Prevent Obesity
- Eliminate Constipation
- Lower Blood Pressure Level
- Lower Cholesterol Level
- Lower Blood Sugar Level
- Strengthen Bones and Teeth
- Maintain Healthy Eyes and Brain
Agar History
Agar is called Kanten in Japanese. Kanten was originally created in Japan back in the 1600s. An innkeeper left a Japanese jelly (Tokoroten) outside. The jelly became frozen due to cold weather. Then, he came up with the method for how to make Kanten. This is how freeze dried agar was born!
Over the following centuries, this binding agent produced so many unique sweets in so many local cuisines! Yokan and Kintsuba are popular sweets using agar.
Agar vs. Gelatin
Gelatin is a more popular binding agent in the United States. Let’s compare the difference.
First of all, agar is made out of red algae. The main ingredient is dietary fiber. On the other hand, gelatin is made out of collagen. The main ingredient is protein.
Second, agar is almost zero calories. However, gelatin has 24 calories per 100 g. Therefore, agar diet makes more sense!
Third, agar firms up at a room temperature. Gelatin needs to be refrigerated to solidify.
Finally, gelatin melts at room temperature. However, agar does not melt at room temperature. Agar melts at the temperature of boiling water. Therefore, agar diet is gentle to the stomach. You want to avoid cold food and drink for intestinal flora!
Agar Diet Cooking Method
In Japan, agar is sold in different forms. They are: powder, sticks, noodle, and so forth. The most popular and easiest form is powder. This is the common one that you can find in Asian or health food stores in the United States.
A small amount of powder will bind water. Use 1 teaspoon of powder for 1 cup of water. You will be amazed how much water agar can hold.
First, stir agar powder into warm water before boiling in a pot. Then, continue to cook for a couple of minutes after boiling. Keep stirring and make sure that powder is completely dissolved.
After you pour cooked agar in a container, it immediately starts to solidify. Therefore, no refrigeration required.
You can change the texture of agar as you desire. If you like harder texture, add 1 teaspoon (2g) to 250ml water. If you like softer texture, add 1/2 teaspoon (1g) to 250ml water.
Also, agar powder can be directly combined with ingredients while cooking. Hence, it works well with ground meats. It helps to bind meats and keep moisture inside.
I will not ask you to eat Japanese agar sweets to lose weight. Agar can be very flexible when it comes to cooking. Furthermore, you can cook agar for main dish, salad, soup, and more. Let’s cook 500 calories set meal and experience amazing agar diet!
