In cafés across KL & PJ, plant-based milk has become the default option for wellness-conscious coffee drinkers. While oat milk is great for lactose intolerance and environmental sustainability, it carries a major hidden trap for your blood sugar, Maltose.
📌 The Science Behind the "Oat Spike":
• Liquid Carbohydrates: Oat milk is made by breaking down oats with enzymes, turning complex starches into maltose, a sugar with a higher Glycemic Index (GI) than table sugar!
• Carb Concentration: One cup of oat milk contains 15g to 20g of fast-acting carbs (roughly equal to eating 1–2 slices of white bread in liquid form).
• The Crash: Without enough fat or protein to slow down absorption, that morning oat latte triggers a sharp glucose spike followed by a mid-morning energy crash and sudden hunger.
💡 WeHealth Smart Coffee Swaps:
1️⃣ Switch to Unsweetened Almond or Soy Milk: Both have significantly lower carb counts and higher protein/healthy fat content.
2️⃣ Drink Coffee After Food: Enjoy your oat milk latte after a protein-rich breakfast to blunt the glucose spike.
3️⃣ Ask for "No Added Syrup": Many cafés add extra flavoured syrups to oat milk beverages.
