💡 Smart Nutritional Guidance
Consumption advice
One whole pepper cut into strips with breakfast or lunch provides more than 200% of your daily vitamin C needs and gives a cheerful sweet crunch instead of crackers.
Best preparation methods
Eat it raw and crunchy to keep all of its heat-sensitive vitamin C, or roast it in the oven with olive oil and peel off the thin skin to make a healthy muhammara dip.
Important Nutritional Note
Ripe red bell pepper contains three times as much vitamin C as an orange; it is a true friend for people with diabetes and for healthy blood vessels and arteries.
