What Are the Benefits of Fiber?
Fiber is found in fruits and vegetables, whole grains, and legumes. It can promote good bacteria, which in turn produce fatty chain acids that improve digestive disorders, such as irritable bowel syndrome or IBS.
Fiber can also help reduce your body’s absorption of sugar, which is helpful, especially if you’ve had a high-carb meal. In this regard, it may be beneficial in reducing the risk of diabetes.
Moreover, fiber is good for heart health as it can help lower bad cholesterol or LDL by binding with cholesterol particles in your digestive system and flushing it out before it gets absorbed.
How to Choose a Fiber Supplement - Buying Guide
Here are some key points to consider:
- Determine the type of fiber suitable for your needs
- Get the right dosage by taking 20-25 g of fiber a day
- Buy from trusted brands to guarantee the quality
For more detailed information, read through our buying guide below.
Determine the Type of Fiber Suitable for Your Needs
Fiber could be classified into two types: soluble and insoluble fiber. Both are great additions to your diet but work differently once ingested.
Regulate Blood Sugar and Cholesterol With Soluble Fiber
Soluble fiber can be dissolved in water and in your body's gastrointestinal fluids. It forms a gel-like substance that blocks the body's absorption of fats and sugars. For this reason, soluble fiber is helpful if you want to prevent blood sugar spikes as well as manage your cholesterol levels.
If you want to manage your weight, consuming food that's rich in soluble fiber can also help as it keeps you full longer by slowing your digestion. Since it slows down your stomach's activity, it is also beneficial if you suffer from diarrhea and irritable bowel syndrome or IBS.
Go for Insoluble Fiber if You Suffer From Constipation
Insoluble fiber can’t be dissolved by water, and it mostly stays intact in your stomach. If soluble fiber slows things down, insoluble fiber does the opposite, as it speeds things up in your stomach.
This is particularly helpful if you frequently experience constipation. Moreover, insoluble fiber may also help reduce the risk of hemorrhoids in the colon. Insoluble fiber could be found in nuts, beans, whole-wheat flour, wheat bran, cauliflower, and potatoes.
Get the Right Dosage by Taking 20-25 g of Fiber a Day
Fiber may be beneficial to our diet but consuming too much could cause some unwanted side effects. According to the Department of Science and Technology’s Food and Nutrition Research Institute or FNRI, the recommended intake of dietary fiber for Filipino adults, both men, and women is between 20-25 g per day.
If you eat more than 70 g a day, you could experience gas, bloating, cramps, as well as constipation or diarrhea. And for some people, the effects may even manifest at 40 g. It is then best to follow the recommended amount indicated in the supplement or consult with your doctor first before taking the plunge.
Buy From Trusted Brands to Guarantee the Quality
When it comes to buying supplements, you can never be too careful, considering you will be ingesting them. So make sure you are getting trusted brands to ensure their quality. Perhaps you already have a go-to manufacturer in mind, familiarity with the brand is a huge plus.
However, for those who don’t, you can always check the Food and Drug Administration’s or FDA website to check if a brand is registered.
