Gastroenterologist Says Polyphenols In Olive Oil Are Important For Gut Health

If you’re keen to explore what the nutrients in the food you eat can do for your gut health, it might be a good idea to explore the wonders of polyphenols. In this post, we’ll explain why a leading Gastroenterologist believes that polyphenols are so important for gut health – and how you can make sure to get enough of them in your diet. Polyphenols are a type of phytonutrient found in plant foods, including extra virgin olive oil, that have antioxidant properties.

In fact the European Food Safety Authority has now approved health claims for extra virgin olive oils with polyphenol content of more than 250mg / kg. Morocco Gold olive oil has high polyphenols well above this level.

They’ve been shown to be beneficial for gut health in multiple ways, including by inhibiting bad bacteria, encouraging the growth of good bacteria, and protecting the gut lining.  But don’t take it from us, listen to the words of an expert!

How Can Polyphenol Rich Olive Oil Benefit Your Health?

In the increasingly health-conscious world we live in today, gut health has become not just a topic of interest but a significant concern for many. From health enthusiasts to nutritionists, the quest for the optimal diet that supports a healthy digestive system is ongoing.

Among the various compounds studied for their beneficial effects on our bodies, polyphenols have recently garnered attention, especially from gastroenterologists. But why? What makes these compounds so special, and how do they contribute to gut health?

How to Incorporate Polyphenols into Your Diet

The good news is that it’s relatively easy to increase your intake of polyphenols. Here are some tips:

  • Eat a variety of colorful fruits and vegetables: Aim for a rainbow on your plate to ensure you’re getting a wide range of polyphenols.
  • Savor your tea and coffee: Both beverages are rich in polyphenols, just be mindful of the caffeine content.
  • Don’t forget about nuts and seeds: These are not only great sources of healthy fats but also polyphenols.

Enjoy dark chocolate in moderation: Dark chocolate is not only delicious but also packed with polyphenols. Just make sure it’s high in cocoa content and low in sugar.

Writing in MindBodyGreen.com, Integrative Gastroenterologist Marvin Singh, M.D. says he is always looking for the best foods and nutrients that can help my patients live their healthiest lives. And this has led him to the door of polyphenols.  Pointing out that many of us may be aware of the potential benefits of drinking green tea or adding olive oil to the diet and eating plenty of vegetables but questions if we really know why?

Did you know that part of the reason for these recommendations has to do with compounds called polyphenols? Polyphenols are found in lots of plant-based foods and have been found to have numerous benefits for health.

Research has revealed numerous potential benefits of polyphenols, many of which have to do with reducing the risk of chronic disease or even supporting gut health.

He goes on to list what he calls the most ‘noteworthy perks’ or health benefits of polyphenols:

1. Boost mitochondrial health.

Mitochondria are the powerhouses inside our cells, generating most of the energy we need to function. Over time, oxidative stress and age contribute to the decline in mitochondrial function, and our health suffers as a result. Several studies have shown that polyphenols and their metabolites, like Urolithin A, can help repair and rejuvenate mitochondria. 

2. Protect against pathogens.

Polyphenols also have antimicrobial properties, meaning they can help protect the gut from various pathogens. By inhibiting the growth of harmful bacteria and fungi, these compounds can reduce the risk of infections and support the body’s natural defense mechanisms.

The polyphenols found in green and black tea have been shown to inhibit the growth of different bacteria and viruses such as hepatitis C virus, influenza virus, E. coli, and Salmonella. There is ongoing research on how polyphenols might influence gut health and potentially promote beneficial bacteria, which helps support a strong immune system, as well.

3. Promote cardiovascular health.

Studies have shown that intake of polyphenols from foods like tea, nuts, cocoa, grapes, and legumes may reduce the risk of heart attack, as well as help control cholesterol levels and blood pressure.

4. Promote brain health.

Consuming polyphenols from chocolate and green and black tea on a regular basis has been shown to reduce the risk of brain function decline over time. One study also showed potential benefits for the brain of infants, when mothers consumed polyphenol-rich pomegranate juice.

5. Help to manage weight.

Studies suggest that the polyphenols in items such as green tea, grapes, and turmeric may help support a healthy weight.

6. Gut support.

Polyphenols’ health benefits also come from what happens in our gut when we eat foods containing them. One example is Urolithin A (UA), a compound that is produced in the gut when we eat polyphenols from foods like berries, nuts, and pomegranates.

How to get polyphenols in your diet from Olive Oil And Other Sources

As Dr Singh perfectly summarise, the single most effective way to increase your polyphenol intake is certainly to consume a variety of plant-source foods.   At Morocco Gold, we are delighted to see that a quality extra virgin olive oil (such as our own) takes its place on his list!

  • Olive oil. Extra-virgin olive oil has been shown to have the highest level of polyphenols.
  • Spices and dried herbs. Try cloves, star anise, peppermint, and Mexican oregano.
  • Red wine. Red wine contains several types of polyphenols, including resveratrol.
  • Black and green tea. These beverages are rich in several types of polyphenols, like catechins.
  • Coffee. The antioxidant polyphenols (caffeine, chlorogenic acid, diterpenes, and trigonellinein coffee have been shown to support brain health.
  • Cocoa powder and chocolate. Rich in several types of polyphenols, mainly catechins and proanthocyanidins. 
  • Fruits. Berries (especially dark ones) and pomegranates are a particularly good source of polyphenols, in particular anthocyanins and ellagitannins.
  • Vegetables. Black and green olives, globe artichoke heads, red and green chicory, onion, shallot, and spinach are good sources.
  • Grains. Whole grain flours from wheat or rye have several different types of polyphenols. 
  • Nuts and seeds. Flaxseed is rich in lignans, whereas others like chestnut and walnut, hazelnut, pecan nut, and almond contain other types. 

Polyphenols are found in a wide variety of plant-source foods. These range from fruits and vegetables to herbs and spices to grains and more. A plant-based diet should generally be rich in various types of polyphenols.
