However, according to studies from the World Health Organization (WHO) and the US National Institute of Nutrition (USDA), consuming too much fiber can cause unwanted effects on health.
Here are 5 common signs that your body is getting too much fiber and needs to be adjusted:
Bloating and flatulence
One of the most common signs of consuming too much fiber is gas and bloating. Insoluble fiber from vegetables, whole grains, or legumes may not be fully digested in the small intestine.
According to research from the British Journal of Nutrition, excess fiber will be fermented by bacteria in the large intestine, creating methane and CO2 gas, causing abdominal discomfort.
Diarrhea or loose stools
Soluble fiber, found in fruits and oats, draws water into the intestines, softening stools.
However, if consumed in excess, this fiber can speed up the movement of food through the digestive system, leading to diarrhea or loose stools.
According to the Academy of Nutrition and Dietetics, this is a sign that the body is not able to absorb fiber effectively.
Stomach pain and intestinal cramps
Consuming too much fiber in a short period of time can stress the digestive system, causing abdominal pain and intestinal cramps.
Excess fiber increases pressure in the intestines, especially if you do not drink enough water to aid digestion.
Constipation
Although fiber is often recommended to relieve constipation, consuming too much can have the opposite effect. According to the European Journal of Clinical Gastroenterology, when the body is dehydrated or unable to process large amounts of fiber, insoluble fiber fibers can build up in the intestines, causing blockages and worsening constipation.
Poor absorption of important nutrients
Excess fiber, especially from food sources high in phytates like whole grains, can interfere with the absorption of minerals like iron, zinc, and calcium.
This condition can lead to nutritional deficiencies, fatigue, weakened immune system and other health problems if not treated promptly.
How to control fiber intake?
Stick to the right dosage: WHO recommends that adults consume about 25-30 grams of fiber per day.
Increase gradually: If you want to increase fiber, do it slowly to let your body adapt, avoid suddenly consuming large amounts.
Drink enough water: Fiber needs water to work effectively in the digestive system, so drink at least 2 liters of water per day.
Food combinations: Combine fiber from a variety of sources such as vegetables, fruits, grains and nuts for nutritional balance.
