Not all drinks hydrate the same! The Beverage Hydration Index (BHI) shows how well different drinks keep you hydrated.

• 💧 Water is the baseline with a BHI of 100%, meaning it hydrates you efficiently.
• 🥛 Drinks with a BHI above 100%, like milk, hydrate better thanks to nutrients and slower digestion.
• ☕️ Drinks with a BHI below 100%, like coffee, hydrate less because caffeine has a mild diuretic effect.

So even if you drink the same amount of different drinks (like coffee and milk), they can affect hydration differently.
