How Can Orange Juice Make Your Kale Better?

The video explores the nutritional synergy between spinach and orange juice, highlighting how vitamin C in orange juice enhances the absorption of non-heme iron found in spinach. It explains the differences between heme and non-heme iron, their sources, and the challenges of non-heme iron absorption due to its lower bioavailability. Vitamin C plays a crucial role by reducing the charge of non-heme iron, making it more absorbable, and forming complexes to keep it soluble. Additionally, vitamin C aids in iron transport and storage by stimulating ferritin production, ensuring iron is available when needed.

Which vitamin in orange juice helps increase the absorption of iron from spinach?

• Vitamin D

• Vitamin C

• Vitamin B

• Vitamin A

What is the main difference between heme and non-heme iron?

• Heme iron is more bioavailable than non-heme iron

• Heme iron is found in plants, non-heme in animals

• Heme iron is only found in dairy products

• Non-heme iron is more bioavailable than heme iron

Why is non-heme iron less bioavailable than heme iron?

• It is found only in animal products

• It oxidizes easily and becomes insoluble

• It is more soluble in blood

• It is not affected by vitamin C

How does vitamin C improve the bioavailability of non-heme iron?

• By making it insoluble

• By binding it to heme

• By reducing its positive charge

• By increasing its positive charge

What role does ferritin play in the body regarding iron?

• It converts iron to heme

• It oxidizes iron

• It transports iron to cells

• It stores iron for future use
