Peel Anatomy

About Peels/Rinds

Most of us are familiar with citrus fruits for snacking and cooking.  There is nothing better than a sweet juicy orange with lunch or a squirt of lemon on fish.  Citrus is packed full of healthy vitamins, minerals and fiber that benefit our health as well as our taste buds.  But did you know the peel (rind) of citrus fruit also packs a nutritional punch.  Yes, there is more to a peel than just zesting!

Today modern medicine acknowledges that peels are a good source of insoluble fiber which helps the digestive system run smoothly.  This is something that herbalists have known for centuries.  The Chinese used the rinds of mandarin oranges and bitter oranges for specific health support.  They found it particularly useful for the support of digestive and respiratory health.
