5 health benefits of eating avocado: Study
Avocado is proven to have improved the gut health, which helps strengthen immunity
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 is rich in dietary fibre and monounsaturated fat which impacts the microbes in the gastrointestinal system or 'gut'.
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."
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.
