Following a high-fiber diet could cause bloating if protein intake is higher than carbohydrate intake. Explanations.
It’s all about balance. Researchers at Johns-Hopkins University (Maryland) claim that following a high-fiber diet can cause bloating if protein intake is higher than carbohydrate intake. Their study was published in the journal Clinical and Translational Gastroenterology.
By analyzing data from a clinical trial conducted on 164 people, researchers found that participants were 40% more likely to suffer from bloating by following a diet based on dietary fiber rich in vegetable proteins, than in carbohydrates. .
Dietary fiber, protein, carbohydrates?
To better understand, let’s dissect: dietary fibers are compounds found mainly in vegetables such as dried fruits, lentils, dried beans, or in whole grain products such as oats, flour, bread. , pasta and rice. Fruits and vegetables are also rich or sources of fiber. Precious to our health, fibers contribute to the regulation of our transit and act in the prevention of many diseases such as type 2 diabetes, certain cancers or cardiovascular diseases.
Carbohydrates, commonly called sugars, cover 40 to 45% of our energy needs. It is found in lentils, grapes, noodles, pasta, dried beans or even basmati rice and bananas. Proteins contribute for their part to the construction of muscles, bones, hair, nails or even enzymes and antibodies. It is found in eggs, beef, white beans, canned peas, wheat, flour and even skimmed milk.
Excess salt, risk factor for bloating
There are therefore dietary fibers rich in protein and others in carbohydrates. According to the researchers, it is possible that a “high-protein fiber diet causes a healthy change in the composition of the microbiome”, which would lead to bloating. However, future studies will have to attest to this.
Last year, the team also demonstrated that excess salt was a risk factor for bloating. Uncomfortable and inconvenient, bloating is linked to an accumulation of gas in the intestine. This overproduction of gas can have several causes, mainly related to the hygiene of life and in particular to food.
