“Fruit remains in the human stomach for only about 15 minutes after being eaten.”

The 15-minute figure is not supported by clinical evidence. Whole fruit is a structured, fiber-containing food, not a clear liquid, and standard medical sources describe stomach emptying for solids in hours rather than minutes. Even unusually fast estimates for some fruits are generally above 15 minutes and do not justify a broad claim about all fruit.

“Combining protein with fruit as a carbohydrate source is the optimal macronutrient pairing for human metabolic function.”

No credible scientific source identifies protein paired with fruit as "the optimal macronutrient pairing for human metabolic function." While evidence confirms that adding protein to carbohydrate-containing meals can moderate short-term blood sugar spikes, this narrow benefit does not establish a single pairing as universally optimal. The highest-authority peer-reviewed sources explicitly state that ideal macronutrient balance remains debated and multiple dietary compositions support metabolic health.
