Whenever there is a gut issue the first thing your doctor tells you is to increase the intake of fibre in your diet. There are many foods that are loaded with fibre, but there is one fruit that overpower everything you eat because it is the king of fibre. Say hello to avocado.

Call it bland or whatever you want, but when it comes to your gut health this fruit can single handedly turn things around for you. And a healthy gut is the epicenter for a healthy body. With the help of a strong gut you don’t just help the other organs in your body to work like well-oiled machines, but also maintain your weight.

If you don’t believe us, then read this research which is going gaga about this gut friendly fruit.

Avocado impacts microbes in your gut and keeps it healthy, study

A study at the University of Illinois College of Agriculture, consumer and environmental sciences has revealed that including avocado in your daily diet can help improve gut health.

Avocados are a healthy food that are rich in dietary fibre and monounsaturated fat which impacts the microbes in the gastrointestinal system or ‘gut’.

Sharon Thompson, a graduate student in the Division of Nutritional Sciences at U of I and lead author on the paper, published in the Journal of Nutrition said: “We know eating avocados helps you feel full and reduces blood cholesterol concentration, but we did not know how it influences the gut microbes, and the metabolites the microbes produce.”

The researchers found that people who ate avocado every day as part of a meal had a greater abundance of gut microbes that break down fibre and produce metabolites that support gut health. They also had greater microbial diversity compared to people who did not receive the avocado meals, says the study.

Thompson told, “Avocado consumption reduced bile acids and increased short-chain fatty acids. These changes correlate with beneficial health outcomes.”

The study included 163 adults between 25 and 45 years of age with overweight or obesity – defined as a BMI of at least 25 kg/m2 – but otherwise healthy. They received one meal per day to consume as a replacement for either breakfast, lunch, or dinner. 

One group consumed an avocado with each meal, while the control group consumed a similar meal but without the avocado. The participants provided blood, urine, and faecal samples throughout the 12-week study. They also reported how much of the provided meals they consumed, and every four weeks recorded everything they ate.

While other research on avocado consumption has focused on weight loss, participants in this study were not advised to restrict or change what they ate. Instead, they consumed their normal diets with the exception of replacing one meal per day with the meal the researchers provided.

The purpose of this study was to explore the effects of avocado consumption on the gastrointestinal microbiota. Assistant professor of nutrition in the Department of Food Science and Human Nutrition at U of I and senior author of the study said, “Our goal was to test the hypothesis that the fats and the fibre in avocados positively affect the gut microbiota. We also wanted to explore the relationships between gut microbes and health outcomes.”

The researchers found that while the avocado group consumed slightly more calories than the control group, slightly more fat was excreted in their stool.

“Greater fat excretion means the research participants were absorbing less energy from the foods that they were eating. This was likely because of reductions in bile acids, which are molecules our digestion system secretes that allow us to absorb fat. We found that the number of bile acids in stool was lower and the amount of fat in the stool was higher in the avocado group,” Holscher explains.

Avocado is an energy-dense food so you can easily replace it with a meal

Different types of fats have differential effects on the microbiome. The fats in avocados are monounsaturated, which are heart-healthy fats.

A medium avocado provides around 12 grams of fibre, which goes a long way toward meeting the recommended amount of 28 to 34 grams of fibre per day, says study.

Eating fibre isn’t just good for us; it’s important for the microbiome, too, Holscher stated. “We can’t break down dietary fibres, but certain gut microbes can. When we consume dietary fibre, it’s a win-win for gut microbes and for us.”

Holscher’s research lab specializes in dietary modulation of the microbiome and its connections to health. “Just like we think about heart-healthy meals, we need to also be thinking about gut healthy meals and how to feed the microbiota,” she explained.

Avocado being an energy-dense food is also nutrient-dense, and it contains important micronutrients that Americans don’t eat enough of, like potassium and fibre.

“It’s just a really nicely packaged fruit that contains nutrients that are important for health. Our work shows we can add benefits to gut health to that list,” Holscher added. 

So, toss it in a salad or have it as is – the choice is yours, but include it in your diet for sure.
