It is preferable to consume vegetables regularly and spread out over time rather than eating massive quantities (such as 2.5 kg of carrots) all at once.

This advice is firmly rooted in fundamental nutritional principles. Consuming an excessive amount of fiber (in this case 80g) in a single meal far exceeds daily recommendations (generally 25-30g), which, according to gastroenterological literature, inevitably causes digestive issues such as bloating or cramps (dietary expert opinion). Regarding beta-carotene, science confirms that excessive consumption leads to carotenemia, a benign but real condition where the skin takes on an orange hue, observed in numerous clinical case studies. While severe vitamin A toxicity from diet alone is rare, absorption is optimized by fractional intake rather than massive, one-time doses. The mention of a genetic condition affecting the conversion of beta-carotene is also a recognized biological phenomenon (BCMO1 enzyme polymorphisms). The approach here is pragmatic: it favors digestive tolerance and metabolic efficiency.
