Pomegranate Peel’s Potent Potential
Pomegranates have been enjoying a new surge in popularity in some parts, widely touted for their health benefits. What’s not so widely touted is that most of the bioactive compounds that give these benefits are concentrated in the peel, which most people in most places throw away.
They do exist in the fruit too! But if you’re discarding the peel, you’re missing out:
Food Applications and Potential Health Benefits of Pomegranate and its Derivatives
“That peel is difficult and not fun to eat though”
Indeed. Drying the peel, especially freeze-drying it, is a good first step:
❝Freeze drying peels had a positive effect on the total phenolic, tannins and flavonoid than oven drying at all temperature range. Moreover, freeze drying had a positive impact on the +catechin, -epicatechin, hesperidin and rutin concentrations of fruit peel. ❞
Once it is freeze-dried, it is easy to grind it into a powder for use as a nutritional supplement.
“How useful is it?”
Studies with 500mg and 1000mg per day in people with cases of obesity and/or type 2 diabetes saw significant improvements in assorted biomarkers of cardiometabolic health, including blood pressure, blood sugar levels, cholesterol, and hemoglobin A1C:
- Effects of pomegranate extract supplementation on inflammation in overweight and obese individuals: A randomized controlled clinical trial
- Beneficial effects of pomegranate peel extract on plasma lipid profile, fatty acids levels and blood pressure in patients with diabetes mellitus type-2: A randomized, double-blind, placebo-controlled study
It also has anticancer properties:
- Punicalagin, a polyphenol from pomegranate fruit, induces growth inhibition and apoptosis in human PC-3 and LNCaP cells
- Punica granatum (Pomegranate) activity in health promotion and cancer prevention
- The extract from Punica granatum (pomegranate) peel induces apoptosis and impairs metastasis in prostate cancer cells
…and neuroprotective benefits:
- Long-term (15 mo) dietary supplementation with pomegranates attenuates cognitive and behavioral deficits
- Neuroprotective Effects of Pomegranate Peel Extract
- An Evaluation of the Effects of a Non-caffeinated Energy Dietary Supplement on Cognitive and Physical Performance
…and it may protect against osteopenia and osteoporosis, but we only have animal or in vitro studies so far, for example:
- Pomegranate Peel Extract Prevents Bone Loss in a Preclinical Model of Osteoporosis and Stimulates Osteoblastic Differentiation in Vitro
- Pomegranate and its derivatives can improve bone health through decreased inflammation and oxidative stress in an animal model of postmenopausal osteoporosis
Want to try it?
We don’t sell it, but you can buy pomegranates at your local supermarket, or buy the peel extract ready-made from online sources; here’s an example on Amazon for your convenience 😎
(the marketing there is for use of the 100% pomegranate peel powder as a face mask; it also has health benefits for the skin when applied topically, but we didn’t have time to cover that today)
Enjoy!
