White rice is acts like "empty" carbs on many because they're just pure sugar (albeit in carbohydrates form, a long chain of glucose) without the important fibres. Alcohol might be an apt comparison if we look at calories alone, it will indeed sustain you in terms of energy, but not much else. you would die if you drank only alcohol, even if somehow the ethanol inside didn't affect you whatsoever. There's just no nutrients in it aside from the calorie-heavy macros. White rice is a refined carb by definition.

It hasn't been known for ages as white rice only became popular after WW2 and was unenriched at first, giving millions of people in Asia vitamin B1 deficiency. It was only after that that manufacturers realized what they'd been doing and added the vitamins and other micros back to rice.

So in terms of enriched white rice... you kinda have to trust the manufacturers are enriching their rice properly, preferably with the ground husk of the rice they just destroyed.
