Why do some farts smell and others don’t?
Some farts may be more discreet, while others are more noticeable and even unpleasant. Have you ever wondered why some smell and others don’t? Nutritionist Xevi Verdaguer reveals that the smell of farts is closely linked to our diet. The smell varies depending on the foods we consume, in particular, the proportion of carbohydrates and proteins in our diet.
Carbohydrates present in fruits, vegetables and legumes ferment in the first part of the colon, producing gases such as hydrogen, CO₂ and methane, which do not have an unpleasant odor and are released more quickly. However, if the gases smell bad, it is indicative of the presence of protein in the diet. Proteins, such as meat and eggs, are fermented by bacteria that generate sulfuric acid, responsible for the unpleasant odor in farts. The higher the protein intake, the greater the growth of these bacteria and, therefore, the greater the odor given off by the gases.
The nutritionist highlights that diet influences the quantity and diversity of bacteria present in our intestine. Vegetarians and vegans, by having a diet richer in fruits, vegetables and legumes, have more beneficial bacteria and fewer unpleasant-smelling farts.
Is there a solution?
Given this revelation, the question arises whether there is any solution to control the smell of farts. The key, according to Xevi Verdaguer, is not to stop consuming protein, but to balance the diet. By including a greater variety of foods, the growth of various colonies of bacteria is promoted, which contributes to better digestion and the reduction of the generation of smelly gases.
By balancing your diet with a variety of nutrients, you prevent certain families of bacteria from growing disproportionately, which can lead to discomfort and digestive problems. This bacterial diversity also explains why some people experience more gas with certain foods than others, such as legumes. Those who regularly consume legumes develop an intestinal microbiota adapted to their metabolism, which allows them to digest these foods more efficiently and with less gastric discomfort.
In summary, a varied diet not only promotes intestinal health, but also contributes to better digestion and the reduction of the unpleasant odor associated with farts. Therefore, by including a wide range of foods in our diet, we can enjoy better digestive health and a more pleasant coexistence for everyone.
