Slow intestinal transit is a common problem, often caused by a diet low in fiber and a sedentary lifestyle. Chronic constipation can lead to bloating, abdominal discomfort, and even long-term health issues. In a post on her official Facebook page, nutritionist Mihaela Bilic clearly explained which foods are most effective for accelerating transit, and it’s not just about dried plums.
What Dr. Mihaela Bilic Says
On her Facebook page, Dr. Bilic wrote:
Foods that contain insoluble fiber accelerate transit. These are vegetables and whole grains that reach the colon almost unchanged, where they absorb water, increase volume, and stimulate intestinal contractions.
She emphasized that insoluble fibers are the ones that practically cleanse the intestines, having a mechanical effect.
Vegetables Recommended by Dr. Bilic:
- Raw cabbage
- Celery
- Green lettuce
- Parsley
- Spinach
- Green beans
These vegetables are rich in tough fibers that do not dissolve in water but act like a brush on the intestinal walls, accelerating waste elimination.
Recommended Cereals:
- Wheat bran
- Whole grain oats
- Whole grain bread
- Brown rice
According to Dr. Bilic, whole grains are essential in the daily diet for healthy transit, being a natural source of insoluble fibers that act like a sponge in the colon, attracting water and increasing the bulk of the stool.
Benefits of Vegetables and Cereals Rich in Insoluble Fiber
1. Accelerating Intestinal Transit
Insoluble fibers are not digested by the body but pass quickly through the digestive tract. They add bulk and weight to the stool, helping it move more quickly through the intestines. This process prevents constipation and maintains the natural rhythm of elimination.
2. Natural Detoxification of the Colon
Foods with insoluble fibers contribute to the elimination of toxins from the body, helping the colon function efficiently. By cleaning the intestinal walls, they reduce the risk of accumulating harmful substances.
3. Regulating Appetite
Vegetables and whole grains have a low caloric content but a high volume, which helps maintain the feeling of fullness. They are excellent for people who want to lose weight without feeling hungry.
4. Reducing the Risk of Digestive Diseases
Slow intestinal transit promotes excessive fermentation and inflammation. Insoluble fibers, through their cleansing effect, can reduce the risk of diverticulitis, hemorrhoids, and even colon cancer.
5. Improving the Gut Microbiome
Insoluble fibers support the balance of the intestinal flora, nourishing beneficial bacteria. A healthy microbiome is essential for immunity, digestion, and even mental balance.
Contraindications and Precautions
Although insoluble fibers are extremely beneficial, they are not recommended in all cases. It is important to keep in mind:
- In ulcerative colitis, Crohn’s disease, or other forms of active intestinal inflammation, tough fibers can irritate the intestinal mucosa.
- Sudden and excessive consumption of fibers can lead to bloating, gas, or abdominal discomfort, especially if not accompanied by sufficient water intake.
- People with irritable bowel syndrome (IBS) may have a harder time tolerating insoluble fibers as they can exacerbate symptoms in some cases.
It is recommended to gradually introduce fibers into the diet and to drink at least 1.5-2 liters of water per day to support their beneficial effect.
