Stressed? Eat a Purple Potato

Stressed? Eat a Purple Potato

Key Takeaways

  • Adding several servings of purple potatoes in your diet can reduce blood pressure and manage weight gain.
  • Potatoes are rich in vitamin C and potassium.
  • Consuming the skin of potatoes can add more fiber content to your diet.

A recent study shows that if an individual consumes two servings of purple potatoes in his or her diet, it can help to reduce blood pressure and control weight gain. The study, published in the Journal of Agricultural and Food Chemistry, had 18 middle-aged participants.

The participants of the study were divided into two groups. In one group, the participants were assigned a diet that required them to eat the skin and flesh of eight small purple potatoes, two times a day, for four weeks. The other group had a normal diet that did not include potatoes in their meals. During the second month of the study, the two groups switched their diets.

Each participant's blood pressure was recorded regularly. In the analysis of the changes in blood pressure, the two groups portrayed that those who had purple potatoes demonstrated a reduction of 4% in the diastolic pressure and a drop of 3% in the systolic reading.

Out of the 18 participants, 14 of them had high blood pressure and were on medications to regulate their blood pressure. Even a small drop in blood pressure helps them to control cardiovascular diseases. Although the group that was required to consume potatoes had more calorie intake than the other group, the body weight of the individuals in that group did not show any changes. This was notable because seven of the participants were obese and six participants could be categorized as overweight.

The inclusion of purple potatoes in one's diet can lower blood pressure, the risk of heart diseases, and the risk of stroke without any weight gain.

Purple potatoes have an abundance of antioxidants, such as anthocyanins, carotenoids, and phenolic acids, that are helpful in reducing chronic inflammatory diseases like heart diseases and stroke. Purple potatoes are also rich in cholorogenic acid, a chemical that has been linked with reducing blood pressure in animal studies. One can have the best of these pigments and antioxidants by microwaving the purple potatoes and including the skin in consumption.

Any type of potato is rich in vitamin C and potassium, and consuming the skin of the potato adds more fiber content in your diet. White potatoes have fewer plant pigments when compared to purple varieties, and similar effects with white potatoes are yet to be ascertained by appropriate studies.
