In need of better gut health? The Mediterranean diet could help.
A new study by scientists found that eating a plant-based diet enhanced the good bacteria living in the gut by up to 7 percent as compared to only 0.5 percent from eating a more meat-centric diet.
The research team designed the study to mimic human Western and Mediterranean type diets that could be controlled and analysed over a sustained period of time.
The study group was randomized to either Western or Mediterranean diet groups and studied for 30 months. The Western diet consisted of lard, beef, butter, eggs, cholesterol, high-fructose corn syrup and sucrose, while the Mediterranean diet consisted of fish oil, olive oil, fish meal, butter, eggs, black and garbanzo bean flour, wheat flour, vegetable juice, fruit puree and sucrose. The diets had the same number of calories.
At the end of the 30 months, the research team analysed the good and bad bacteria that live in the gastrointestinal tract. They found the gut bacteria diversity in the Mediterranean diet group was significantly higher than in the group that ate the Western diet.
There are about 2 billion good and bad bacteria living in the human gut. If the bacteria are of a certain type and not properly balanced, our health can suffer.
The study showed that the good bacteria, primarily Lactobacillus, most of which are probiotic, were significantly increased in the Mediterranean diet group.
The scientists reported that the data revealed in this study should be useful for further studies aimed at understanding the diet-microbiome-health interactions in humans, including obesity, type 2 diabetes, cardiovascular disease and psychiatric disorders.
The study findings are published in the April 25 online edition of the journal Frontiers in Nutrition.
As part of a healthy diet and lifestyle, Sona has a range of probiotics which promote good gut health.
There are eight Sona probiotic products available across the range including:
New to the range- Sona Pro25Biotic, Sona UltraBiotic- Active Lives, Sona UltraBiotic- For Women
