There is a dish that not only has beautiful colors but is also considered a superfood due to its high nutritional value and many health benefits.
Purple is not only beautiful but also a sign of power from the antioxidant anthocyanins - which have the ability to fight diseases. It is thanks to the high content of this purple antioxidant that purple sweet potatoes become a miracle drug, doing many miracles for health.
Purple sweet potatoes (also known as purple potatoes) have many nutritional values. In addition to antioxidants, they are also high in fiber, vitamin C and potassium, which can help with weight loss, boost immunity and heart health. Their low glycemic index also makes them a great choice for maintaining stable blood sugar levels, which is beneficial for people with diabetes.
From anti-inflammatory to heart protection, cancer prevention, purple sweet potatoes do wonders for your health
Here's why you should include purple potatoes in your weekly diet, according to health news site Eating Well.
Source of antioxidant power
Purple potatoes are packed with anthocyanins, with 150% more antioxidants than blueberries, making them a great option for preventing chronic disease.
The Japanese elixir of longevity
The link between these potatoes and longevity is no coincidence. They are rich in DHEA (dehydroepiandrosterone), a precursor to essential anti-aging compounds. The Okinawans of Japan, famous for their longevity, have higher levels of DHEA thanks to their consumption of these purple potatoes.
Good for the heart
Studies have shown that purple potatoes can reduce systolic blood pressure by 3.5%; reduce diastolic blood pressure by 4.3%; reduce arterial stiffness and have effects similar to blood pressure medications.
Researchers also found that people who ate 200g of purple potatoes (about one medium-sized potato) every day, after two weeks, had significantly improved blood pressure, according to Eating Well .

Anti-cancer
Research has shown that antioxidants and anti-inflammatory compounds in purple potatoes can inhibit the growth of cancer cells.
Purple potatoes have the ability to inhibit the activity of β-catenin and interleukin-6 (two substances that play a role in promoting inflammation and colon cancer) and inhibit the formation of dangerous byproducts. This could be good news for the future treatment of this common cancer.
Additionally, another study found that anthocyanins in purple potatoes have the ability to target and inhibit bladder cancer cells. The powerful antioxidant compounds in these potatoes show potential to help prevent and slow the growth of certain types of cancer cells, according to Eating Well.
Regulate blood sugar
With a low glycemic index (GI 24), purple potatoes provide steady energy without causing blood sugar spikes. Their high fiber content helps keep blood sugar levels stable, while their unique compounds help protect the insulin-producing cells in the pancreas.
Reduce inflammation
A review of studies found that purple potato extract positively affected markers of inflammation, particularly in the liver and kidneys.
The healthiest way to eat purple potatoes
Studies show that microwaving and boiling retain the most antioxidants in purple potatoes. So to maximize the benefits, prepare potatoes in these two ways.
