You might find it strange that orange peels which are mostly known for bringing a zest to our cocktails and skincare products can even be used for improving your heart health. According to a new study led by the University of Florida (UoF), orange peel extracts, rich in phytochemicals, may help boost cardiovascular health.
How Orange Peels Prevent Heart Disease?
Many factors can put your heart at risk. One such factor is gut bacteria. A new study by researchers at the Cleveland Clinic and Tufts University suggested found that some gut bacteria, when they break down certain nutrients during digestion, produce a chemical called trimethylamine N-oxide (TMAO). Interestingly, higher levels of TMAO seem to be associated with an increased risk of developing cardiovascular disease in the future.
The UoF study focused on how the orange peel parts impacted the creation of TMAO. Interestingly, the orange peel's effect wasn't by changing gut bacteria, but by influencing specific enzymes in the body.
To find this, the researchers separated the orange peel into two parts: one part which can dissolve in water, and the other part which can dissolve in oil. They found that consuming the water-soluble part of orange peels, potentially rich in feruloyl putrescine, could be a way to reduce the risk of heart disease without affecting gut bacteria balance.
How To Eat Orange Peels?
All of us are conditioned to remove the peels of vegetables and fruits, seeing them as waste material. So if you need a bit of push to try eating orange peels, here are some of its potential perks beyond its ability to boost heart health:
- Packed with nutrients: Looking at data from the United States Department of Agriculture, orange peels boast more fibre and vitamin C than the juicy flesh inside the orange! They're also a good source of provitamin A, folate, and various minerals
- Potential cancer fighter: Many studies including one by Iranian researchers published in Biomedicine & Pharmacotherapy suggest that the antioxidants present in orange peels have the potential to act as anti-cancer agents.
- Digestive aid: The good amount of fibre in orange peels can promote healthy digestion and regular bowel movements.
- Boosts immunity: Vitamin C in orange peels is a well-known immune system supporter, helping your body fight off infections.
- Skincare benefits: The antioxidants in orange peels may help protect your skin from damage and promote a healthy glow.
Till practical applications of the UoF study are not boiled into consumable products like orange peel supplements or orange peel extracts for consumption, there are other ways by which you can eat orange peels:
- Zest it: The most common way to use orange peels is to zest them. Use a zester or fine grater to remove the brightly coloured outer layer, avoiding the white pith which can be bitter. You can sprinkle orange zest on yoghurt, oatmeal, cakes, muffins, salad dressings, and marinades.
- Infuse your drinks: Steep orange peels in hot water to make a fragrant citrus tea. You can also add them to cocktails or mocktails for a refreshing twist.
- Candied peels: For a sweet treat, try making candied orange peels. Boil the peels in sugar syrup until soft and translucent. Enjoy them as a snack, chop them up and add them to desserts, or use them to decorate cakes.
- Salads and smoothies: Finely chopped orange peel can add a surprising brightness to salads. Start with a small amount to balance the bitterness. You can also incorporate them into smoothies for a citrusy boost.
One thing to note is that the UoF study is still in its early phase and requires further research before orange peels can be suggested as a treatment for heart disease. However, there is no harm in enjoying the unique flavour or orange peels, which may also boost your heart and overall health in the process. However, you should always consult a healthcare professional before making significant dietary changes, especially if you are doing it as a way to treat diseases.
