Improve Your Gut Health with Polyphenols
Polyphenols are in many plant foods and provide many health benefits! I am excited to share a few ways that polyphenols help boost gut health and in addition, how they prevent other chronic diseases. We will check out some of the different types of polyphenols and which foods are full of them! And I have a new recipe that I hope that you will love!
What are Polyphenols?
Polyphenols are powerful phytochemicals that help our body through an amazing antioxidant activity that helps fight off inflammation in our body to reduce free radicals which increase our risk for chronic disease.
How Do Polyphenols Affect Your Body?
Let’s talk about how polyphenols improve our health.
While I was researching for Vine Ripe Nutrition’s Digestive Wellness Program, I was pleasantly surprised to learn how polyphenols help improve GI Health. This was also reinforced in a recent webinar presented by Kate Scarlata on “A Holistic Approach to IBS” which was sponsored by Fody Foods which had some wonderful resources that I can use.
Health Benefits of Polyphenols in Gut Health
How do polyphenols improve GI Health?
Because polyphenols are not easily digested, they act inside our body similar to prebiotics by nurturing and helping increase the number of healthy bacteria in our gut. And they help reduce the potentially bad bacteria. The healthy bacteria help improve our body’s ability to use polyphenols in other ways to improve our health. This makes it sort of a win/win, symbiotic relationship! Here is a researcj article that highlights a little more about this.
Other Health Benefits of Polyphenols
I always knew that foods containing polyphenols were good for us but researching more on what they do was almost overwhelming in a very good way.
More research needs to be done in these areas but these are very exciting possibilities where so many chronic dieases can really be improved by what we eat!
Health Benefits of Polyphenols in Cardiovascular Wellness
Two ways that polyphenols help promote a healthy heart include their role in reducing inflammation as well as their antioxidant activity to help remove free radicals in the blood vessels. These actions help lower LDL cholesterol and blood pressure to help increase HDl cholesterol. Check out this article which has more about how all this works.
Health Benefits of Polyphenols in Our Brain
The antioxidant benefits of polyphenols along with the fact that they help improve the health gut are some of the big reasons that they help prevent neurogenerative brain disease. There has been much research on the relationship between a healthy brain and gut. In addition, the polyphenols known as “stilbenes” most commonly found in blueberries may promote the secretion of beneficial brain promoting chemicals like “brain-derived neurotrophic factor (BDNF). You can find out more in this informative research article from 2015.
More research is being done to see how polyphenols affect anxiety, depression and other mood disorders but much more needs to be studied how they benefit.
Health Benefits of Polyphenols Cancer in Prevention and Survival
These medicinal antioxidants also play an important role in cancer prevention and may even affect many of the cellular mechanisms which are involved in cancer growth. The fact that polyphenols help reduce our body’s inflammation and boost our immune system. I like the nice overview that the article on the different types of polyphenols that are in our food. It is just an important reminder that the more variety that we have of medicinal plant foods that we have the more benefits that we get!
Health Benefits of Polyphenols Skin
In addition to the above benefits, research has shown that polyphenols even protect our skin from the harmful effects of UV rays which gives our sunscreen an additional boost when we eat these foods. The antioxidant benefits from these foods also provide a real anti-aging advantage. You can find out more about how polyphenols benefit our skin here.
Health Benefits of Polyphenols to Prevent and Manage Diabetes
Because of the anti-inflammatory role in the body, polyphenols provide a big benefit to not only preventing Type 2 Diabetes but they might also have a role in helping improving blood sugar. You can check out this entire article about these benefits.
Polyphenols In Achieving Healthy A Body Weight
I have included an article below that highlights the Potential Health Benefits of Polyphenols and their relationship to a healthy weight. For instance, a few of these ways include assisting the body to burn fat, limiting the ability to store excess fat and reducing inflammation in the body, You can find out more details here.
What About Polyphenol Supplements?
It is best to get beneficial food components like polyphenols from food itself. Supplements are not well regulated and may not always have the active ingredients that they say they have and some may even have less healthy by-products in them. There also is a food synergy where all the parts work better together than a small isolated piece.
Types of Polyphenols In Our Foods
Before really jumping into this research, I usually thought of only revesterol and anthocyanins as polyphenols with their blue, violet and red hues. And are known for their antioxidant activity benefiting heart health and preventing cancer. I have learned from putting this together that they are much more than that!
From my research, I learned that there are two main types of polyphenols.
And within each of these two main types, there are subcategories within them. You might wonder like I did, “why so many names it is so confusing!” Well thinking back to my old chemistry and life science courses, I realized chemical structure and biological activity have a role into why there are so many names to keep these beneficial plant chemicals straight!
Subcategories of flavonoids include:
Subcategories of pheolic acids include:
- hydroxybenoic acid
- hydroxycinnamic acid.
And within these smaller subcategories, each of them is further divided into individual members within each subcategory. Some of these beneficial phytochemicals that you might be familiar with include:
- EGCG found in green tea
- Quercetin found in apples
- Geinstein found in soy
- Ellagic acid found in berries
- Revesterol from grapes
These are all a type of polyphenols!
Recipe Rich in Polyphenols
Today’s recipe is rich in polyphenols, beautiful color and delicious taste. Above all, I love the interesting cultural background of my recipe for Behl.
What is Behl?
Behl is an appetizer or salad often served by street food vendors in India. It often contains something crunchy like puffed rice. People enjoy this salad/snack for it’s sweet, salty, tart and spicy components that make it rich in flavor. Other familiar ingredients in Behl include cabbage, tomatoes, and potatoes.
You can serve this recipe as a side dish to your favorite Indian dish, for example, this recipe below or I think it would be delicious as a side dish with anything!
Purple Cabbage Behl Salad
Inspired by a delicious salad served seasonally at one of our favorite restaurants in Asheville, Chai Pani which features Indian Street Food. I used purple cabbage in my recipe and added sweet potatoes. I love the green and red of the cilantro/green onion and tomatoes. You can even mix purple and green cabbage! Serve it over quinoa if desired. Top with roasted peanuts and drizzle with chutney!
4 cups thinly sliced purple cabbage
1 medium sweet potato, baked until still slightly firm
½ cup chopped tomatoes
2 green onions chopped
1/4 cup garlic infused oil
1/3 cup lemon juice (you could even use lime instead)
1 jalapeno pepper, chopped and seeded
1/3 cup chopped cilantro
Garnish with additional cilantro, green onions, cilantro chutney (see recipe below), and peanuts.
This chutney recipe is from Bon Appetit. I included it because I like the simplicity of it. Feel free to create your own or make one of the other great ones out there.
After sweet potatoes have cooled, peel and cut them into 1/2 inch cubes. Add thinly sliced cabbage and tomatoes in a medium bowl. Lightly mix in the lemon/lime juice, olive oil, salt, and pepper to taste. Toss in the sweet potatoes and green onions.
Add sliced avocado to the top and garnish with your favorite toppings or serve them on the side.
