Vegetables: broccoli, spinach, carrots, artichokes, onions and garlic are particularly rich in fibers.
Fruits: berries, apples with skins and bananas.
Legumes: lentils, chickpeas, black beans
Whole Grains: oats, quinoa, barley, brown rice.
Fermented foods why are beneficial in our diet
Fermented food are rich in probiotics promoting a positive effect on gut bacteria. It is essential to add these foods to our daily meal routines if we want our microbiome to benefit. It is suggested to comsume yogurt or kefir for breakfast and sauerkraut as a side. Choose products that specify “live and active cultures”. These foods includes:
Yogurt with live cultures or kefir
Sauerkraut
Kimchi
Miso
Kombucha
Introduce Prebiotic Foods
Prebiotic foods to actively feed your gut microbiome. It is of vital importance to include prebiotics in your daily diet along side your cooking, consuming home made smoothies and cereals, mix greens into stir fries and soups. Prebiotics food include:
Chicory root
Garlic
Onions
Leeks
Asparagus
Leafy vegetatble
Dandelion greens
Bananas
Importance of Diversity
The more diverse your diet the more diverse your microbiome, simple as that! Each food type has the ability to introduce new nutrients that feed different bacteria. The more diverse nutrients we introduce the more diverse bacteria cultrures we introduce.
Try new fruits, vegetables and grain each week and incorporate seasonal produce to increment variety in your diet.
By reducing sugar rich and processed foods you will increase the microbiome activity increasing beneficial effects to your health. A diet rich in sugar and processed foods will increase harmful bacteria and reduce or even block the good bacteria needed for an healthy microbiome.
Avoid sugary drinks and snacks, replace processed snacks with whole foods such as nuts, seeds, or fresh fruits.
It is very important to stay hydrated so that the mucosal lining present in the gut will be fully supported keeping the microbiome enviroment actively enagged in the correct metabolism of nutrients and will feed the good bacteria.
It is advisable to drink at least 8 cups of water a day, which includes herbal teas or infused water.
Benefit of Healthy Fats
Omega-3 fatty acids and unsaturated fats support the gut microbime too. For example, you could start to cook with olive oil instead of butter. Simply by adding an handfull of nuts and seeds to your meals you could easly implement a good amount of daily fatty acids to your daily food intake. Here rich of omega-3 fatty acids foods are:
Any fatty fish such as salmon and mackerel
Nuts and seeds like chia and walnuts
Extravergin olive oil and avocado oil.
Sample day for a Microbiome-Friendly Diet
Breakfast: Greek yougurt or kefir with mixed berries, chia seeds and a drizzle of honey
Snack: An apple with almond butter
Lunch: Lentil soup with whole-grain bread and a side of stir fried garlic spinach
Snack: Carrot sticks with hummus
Dinner: Garlic salmon with quinoa and roasted asparagus
Dessert: A piece of dark chocolate with green tea
By consistently incorporating these habits, you will nurture a triving and diverse microbiome, which can enhance digestion, immunity and your overall health.
In conclusion, adopting a diet rich in minimally processed, plant-based foods is highly beneficial for supporting a healthy and diverse gut microbiome. Incorporating a variety of fruits, vegetables, whole grains, legumes, nuts, and seeds provides essential prebiotic fibers that nourish beneficial gut bacteria. Additionally, including fermented foods such as yogurt, kefir, sauerkraut, and kimchi can introduce probiotics, further enhancing microbial diversity and promoting gut health.
Limiting the intake of ultra-processed foods, which often contain additives like emulsifiers, is also advisable, as these can negatively impact the gut microbiota. By focusing on a diverse, plant-rich diet and mindful consumption of processed foods, one can effectively support and maintain a healthy microbiome.
