It’s pretty common practice to drink Orange Juice when feeling a little under the weather, right?
Vitamin C is a strong antioxidant, increases iron absorption, and is well-regarded for its role in supporting and protecting the immune system. There are countless foods that are chalked full of Vitamin C (check here for a comprehensive list) and it’s true that Orange Juice is high up on the chart – so why should OJ actually be avoided when sick?
Vitamin C is absorbed into the blood stream via a receptor called GLUT-1 which is also a major receptor for glucose (sugar). Since Orange Juice is quite high in sugar when you drink a glass of OJ, both the sugar and Vitamin C end up competing to be taken into the blood stream via the GLUT-1 receptor and therefore less will be received. By removing the fiber from fruit, the sugar is quickly absorbed and causes the absorption of Vitamin C to be compromised.
With the fiber in tact, the sugar absorption will be slow and steady making room for more Vitamin C to find its way into your blood stream through the GLUT-1 receptor. If you’re looking to increase your intake of Vitamin C, try going for whole food based choices like bell peppers, kiwis, broccoli, strawberries, papaya, kale, cantaloupe, pineapple, and of course…oranges!
