Season

Food Combinations & Timing
Avoid consuming with: Milk and dairy products
Waiting Interval: Wait at least 1-2 hours
The citric acid instantly curdles milk proteins in the stomach. While curdled milk is not toxic, curdling it rapidly in the stomach can lead to cramping, gas, and severe acid reflux. Consume citrus fruits at least 1-2 hours away from milk.
Circadian Digestion Rule: Fruits are best consumed during the daytime. As the sun sets, human metabolism slows down and insulin sensitivity decreases as melatonin rises. Eating high-fructose fruits after sunset can trigger blood sugar spikes.
Scientific Reason: Fruits digest extremely rapidly (often within 20–30 minutes). When eaten late at night when gut motility slows down, they can sit and ferment in the digestive tract, leading to gas, bloating, acid reflux, and disrupted sleep.
