Fiber is the part of a plant that body can’t break. They are also known as fibrous carbohydrate – just they can’t be digested by a human digestive system. As it can’t be digested that doesn’t mean fiber don’t have any importance. The nutrients that can’t be digested can increase bowel moment, flush cholesterols and carcinogens out of the body.

Fibers are classified depending on its solubility in water:

Soluble fiber: Dissolves in water to form a gel-like material. It helps to reduce cholesterol and control blood sugar. They are feed by gut bacteria “good bacteria”, which are responsible for better health.

Insoluble: Does not dissolve in water. They provide bulk to stool and promotes regularity and prevents constipation.

Health Benefit of Eating Fiber

Fiber provides a range of benefits due to the property of improved detoxification. Let’s have a look over the crucial benefits you should know before consuming fiber.

1. Improves Digestive Health

Fiber makes the stool bulkier, allowing it to passes easily thus preventing the feeling of being constipated.

As you know that there is two fiber- soluble and insoluble.

Soluble fiber increases the stool water-content so have a laxative effect. But insoluble can add dry weight without absorbing water so it can have a constipating effect. For better digestive health you need to get both fibers from your diet, which you can get by combining foods from each food types.

2. Heart Health

Soluble fiber is a part of a heart-friendly diet. Consumption of soluble fiber lowers blood cholesterol by limiting the absorption of biles in the intestine.

During that process, an excess of LDL cholesterol is absorbed from the blood by the bile salt produced by the liver.

Lower absorption and transfer of LDL of cholesterol from the blood – both results lower LDL cholesterol in the blood which is good for heart health.

3. Diabetes

Sugar spikes are common due to lack of fiber in food. Due to frequent sugar spikes the risk of Type 2 Diabetes increases. Eating fiber-rich food (mostly soluble) slow down the absorption of sugar – preventing sugar spike thus protecting from Type 2 Diabetes.

4. Good Bacteria Food

Gut Bactria has lots of importance to our health.

We have just started to explore the benefits of healthy gut bacteria and still there a lot to know. It is found that the majority of immune function is influenced by gut bacteria.

Along with immunity, there are many roles a gut bacteria plays. To support healthy gut flora we need to eat soluble fiber on which these bacteria feed.

5. Weight Loss and Weight Management

The final yet the most concerned topic.

The common interest among fitness freak about increasing fiber intake is to lose weight and to maintain weight.

If you are looking to lose and manage weight, fiber will be to best nutrient.

Fiber isn’t digestible so it doesn’t provide calories. Eating fiber-rich food can make in full in less serving and calories. While fiber slows down the digestion, which keeps you full for long without any energy crash.

With better satiety and fewer hunger pangs, you start to lose excess weight and it is also helpful in managing those weight.

How much fiber?

Your fiber intake will depend on age and gender, its recommended to eat 21 to 38 grams per day for optimal health.

Tip of warning: If you trying to add more fiber to your diet, then start slowly. Bulking with fiber-rich food quickly can make you feel bloated and constipated. Gradually increase your fiber intake to prevent any possible digestive issue. You should increase your water intake as you start to increase your fiber intake.
