Among these three causes, neutral fat is difficult to control with medication.
Neutral fat is the source of body fat. If neutral fat increases too much, it is stored as body fat.
The cause that increases neutral fat too much is over consumption of carbohydrate including sugar.
Carbohydrate is the source of our energy, but the quantity of the muscle decrease with age, the unused energy is left and becomes neutral fat in the blood stream. As a result of that, body fat increases, liver fat can be caused or the risk of cardiac infarction can rise.
The difficult point in neutral fat is that neutral fat is easy to store but is difficult to decrease.
How can we efficiently decrease neutral fat?
Many people in a town in Japan, where Jerusalem artichoke is eaten a lot, have lower neutral fat than the guideline (150 mg/dl).
Jerusalem artichoke is rich in inulin which is a type of water soluble dietary fiber.
Carbohydrate is usually absorbed from the small intestine and goes into the blood stream. Inulin goes into our body, gets mixed with water and becomes jelly-like state. Jelly-like inulin wraps around carbohydrate and the carbohydrate goes to the large intestine without being absorbed from the small intestine.
Inulin becomes feed of intestinal bacteria in the large intestine. On top of that, inulin doesn’t become feed of bad bacteria but becomes only feed of good bacteria. As a result of that, only good bacteria such as Bifidobacteria, Lactic acid bacteria increase in the intestine. Substances produced by good bacteria influence the liver, suppressing the synthesis of neutral fat in the liver.
What vegetables are rich in inulin except Jerusalem artichoke?
Inulin is one of nutrition that is difficult to extract, so the study of inulin has not proceeded very much all over the world.
In this experiment, the amount of inulin contained in 10 kinds of vegetables is measured.
Jerusalem artichoke that contains inulin most: 18 g (within 100 g)
1. Garlic: 12.5 g
2. Burdock: 5.4 g
3. Onion: 4.3 g
4. Asparagus: 2.5 g
5. Lotus root: 0.1 g
6. Kabocha squash: 0.1 g
7. Japanese mountain yam: 0.1 g
8. Shishito (sweet green pepper): 0 g
9. Eggplant: 0 g
10. Tomato: 0 g
A 47 years old woman whose neutral fat was 152 mg/dl (guide line: 150 mg/dl) and who liked alcohol and carbohydrates tried to take inulin 10 g per day from the vegetables containing a lot of inulin for 5 days without changing usual lifestyle. After the 5 days trial, her neutral fat decreased to 139 mg/ dl.
