The Importance of Controlling Blood Sugar Levels through Diet

The relationship between diet and blood sugar levels and the risk of illness that accompanies high blood sugar

It is extremely important to control your blood sugar levels through diet,such as by consuming meals that don’t cause blood sugar spikes. Your blood sugar levels rise after eating.

When too much glucose is consumed, insulin secretion is insufficient, or the vagus nerve causes abnormalities in insulin secretion. As a result, sugars are not broken down and remain in the bloodstream, where their concentration (your blood sugar level) rises. When blood sugar levels are high, your blood becomes more concentrated, resulting not only in dehydration but also in increased risk of diseases like diabetes, heart attack, and cirrhosis of the liver.

Among these, diabetes is especially difficult to manage once it occurs, and since it causes blood sugar levels to remain high for long periods of time, it can cause a number of complications. In order to minimize these risks, it is important to always take care that your blood sugar levels do not become elevated. If you are someone with higher blood sugar levels, you may want to reexamine your eating habits. You can start by knowing how many calories you need in a day, avoiding an unbalanced diet and overeating, eating three meals a day, and regularly eating nutritionally balanced meals.

Increased sleepiness due to high blood sugar

When sugar is absorbed from meals, blood sugar levels rise. The hypothalamus, located in the brain, detects this and causes activity in the parasympathetic nervous system which leads to insulin being secreted from the islets of Langerhans in the pancreas. This means that the more sugar you consume, the more your parasympathetic nervous system is stimulated, leading to sleepiness after meals.

Soluble fiber slows the absorption of sugars

Sugar absorption takes place in the small intestine, and it is thought to be best to consume meals that slow this absorption. Soluble fiber is one nutrient that slows the absorption of sugars. Indigestible dextrin is well known as one of soluble fiber’s components.

Summary: Ideal meals for controlling blood sugar levels

For the reasons given above, the following types of eating habits are thought to be ideal for controlling blood sugar.


1. Eating an appropriate amount so as to avoid taking in too much sugar (avoiding binge eating, etc.)

2. Taking care to consume meals containing as little sugar as possible (There is no official recommended sugar intake.)

3. Chewing well (This stimulates the ventromedial hypothalamus and prevents overeating.)

4 Actively consuming soluble fiber before and during meals

These are all proposed as effective eating habits for controlling rapid rises in blood sugar levels.


Arame and seaweed contain nutrients that are thought to make it more difficult for blood sugar levels to rise, making them a great part of meals meant to slow the rise of blood sugar levels after eating.

One such nutrient that has received a great deal of attention in recent years is soluble fiber. This substance is used around the world in dietary supplements, including indigestible dextrin. Soluble fiber has been shown to slow the absorption of sugars in the small intestine. When taken before meals, it is particularly effective in slowing the absorption of sugars and preventing a sudden rise in blood sugar levels after eating. The stickiness of okra and avocados is actually soluble fiber. (Light, smooth soluble fiber also exists.) There are multiple types of soluble fiber, and their most well-known components include pectin, inulin, and agarose.

Seaweed, including arame, mainly contains plentiful amounts of a soluble fiber known as sodium alginate.
