What Are Probiotics and Where Are They Found? Post Date : December 20, 2024 Gut Health Healthy Diet 2 minutes read You have probably heard doctors and nutritionists speak about probiotics, but you may have heard them called microorganisms or “good” bacteria. There are many different forms of probiotics, and they can be found in some foods or taken as supplements. But why might you need them? Our gut is home to trillions of bacteria, fungi, and other microorganisms, collectively known as the gut microbiome. This complex community plays a vital role in: Digestion: Helping to break down food and absorb nutrients. Immune function: Supporting the immune system and protecting against harmful pathogens. Mental health: Influencing brain function and mood. There are several factors that can disrupt the balance of our gut microbiome, including: Antibiotic use: Antibiotics kill both good and bad bacteria, which can disrupt the gut microbiome. If you are taking antibiotics, probiotics are recommended to replenish the ‘good’ bacteria in your gut that had been damaged or killed by the antibiotics. Poor diet: A diet high in processed foods or Ultra Processed foods, sugar, and unhealthy fats can negatively impact the gut microbiome. Stress: Chronic stress can also affect the balance of gut bacteria. Probiotics can help restore this balance and promote a healthy gut. How Do You Get Probiotics? Probiotics can be found in the food and drink we consume. Many fermented foods naturally contain probiotics, such as: Kefir A fermented milk drink that’s packed with probiotics and nutrients, making it a great addition to a healthy diet. Here’s a breakdown of why it’s good for you: 1. Rich in Probiotics: Kefir contains a diverse range of beneficial bacteria and yeasts, more so than many yogurts. These probiotics can help improve gut health by promoting a healthy balance of gut bacteria. A healthy gut is linked to better digestion, a stronger immune system, and even improved mental health. 2. Good Source of Nutrients: Kefir is a good source of calcium, which is essential for strong bones and teeth. It also contains other important nutrients like vitamin D, phosphorus, magnesium, and vitamin K. 3. May Improve Bone Health: Studies suggest that kefir may help improve bone density and reduce the risk of osteoporosis, likely due to its high calcium and vitamin K content. 4. May Have Antibacterial Properties: Some studies indicate that certain probiotics found in kefir may have antibacterial effects, helping to fight off harmful bacteria. 5. May Help with Digestive Problems: Kefir may help alleviate digestive issues like irritable bowel syndrome (IBS), some types of diarrhea, and ulcers caused by H. pylori infection. 6. May Improve Allergy and Asthma Symptoms: Some research suggests that kefir may help modulate the immune system and reduce allergy and asthma symptoms. 7. Low in Lactose: The fermentation process in kefir reduces the lactose content, making it potentially easier to digest for people with lactose intolerance. Kombucha A fermented tea drink that has gained popularity for its potential health benefits. Here’s a breakdown of why it’s considered good for you: 1. Probiotics: Kombucha is rich in probiotics, which are beneficial bacteria that can improve gut health. A healthy gut microbiome is linked to various aspects of overall well-being, including digestion, immunity, and even mental health. 2. Antioxidants: Kombucha contains antioxidants, which help protect your cells from damage caused by free radicals. These antioxidants primarily come from the tea used to make kombucha (green or black tea). Antioxidants are associated with a reduced risk of chronic diseases. 3. May Offer Benefits Similar to Tea: Since kombucha is made with tea, it may offer some of the same health benefits, such as: * Improved heart health * Lower blood sugar levels * Reduced risk of certain cancers (though more research is needed in this area) 4. Contains Acetic Acid: Acetic acid, also found in vinegar, is a byproduct of the fermentation process. It may have antimicrobial properties, helping to kill harmful bacteria. Important Considerations: Sugar Content: Some kombucha varieties can be high in sugar. Choose brands with lower sugar content or drink it in moderation. Alcohol Content: Kombucha contains trace amounts of alcohol due to fermentation. While usually very low, it’s something to be aware of, especially for certain individuals. Potential Side Effects: Some people may experience mild digestive issues, especially when first starting to drink kombucha. Overall, kombucha can be a healthy addition to your diet due to its probiotic and antioxidant content. However, it’s important to consume it in moderation and choose varieties with lower sugar levels. If you have any underlying health conditions, it’s always best to consult with your doctor before making significant dietary changes.

Overall, kimchi is a delicious and nutritious food that offers a range of potential health benefits, primarily due to its probiotic content and rich nutrient profile. Yogurt Yogurt is a delicious and nutritious food that’s packed with probiotics. These beneficial bacteria, primarily lactic acid bacteria and bifidobacteria, are responsible for fermenting milk and giving yogurt its tangy flavour. Health Benefits of Yogurt: Improved Gut Health: Probiotics in yogurt support a healthy gut microbiome, crucial for digestion and overall well-being. Bone Health: Some yogurts are fortified with vitamin D and calcium, essential for strong bones. Heart Health: Studies suggest yogurt consumption may be linked to improved heart health. Immune Support: Probiotics may help strengthen the immune system. Choosing the Right Yogurt: Look for “Live and Active Cultures”: Ensure the yogurt label states it contains live and active cultures, indicating the presence of beneficial bacteria. Watch Out for Added Sugar: Opt for plain yogurt or varieties with minimal added sugar. Consider Greek Yogurt: Greek yogurt is higher in protein and lower in lactose than regular yogurt. Pickles Pickles are commonly pickled cucumbers preserved in a solution of salt and water. But in fact, you are able to pickle much more than the humble cucumber. You are able to pickle, tomatoes, jalapenos, carrots, watermelon and many more. How do you create a pickling solution? To create the pickling solution, add dechlorinated water to a jar or fermentation tank, adding 2 tablespoons of sea salt per litre of water (not table salt as this contains high levels of sodium). Allow the salt to dissolve before adding your vegetables. It is also recommended that you add mustard seeds, garlic and other fresh herbs to stabilise the fermentation. It’s important to note that pickles made with vinegar do not contain live probiotics. Cheese While many cheeses are fermented, not all contain live and active cultures, which are the beneficial bacteria we call probiotics. To ensure you’re getting probiotic benefits from cheese, always check the label for phrases like ‘live and active cultures’. Semi-hard cheeses such as cheddar, mozzarella, gouda and cottage cheese, may contain higher levels of probiotics than other types of cheese that are aged for longer periods of time. Cheese is highly nutritious and an excellent source of protein. It’s also rich in important vitamins and minerals, including: vitamins A, B6, B12, D, and Kcalciumiodinemagnesiumpotassiumphosphorusseleniumzinc Learn more about Fermented foods here (link to blog) Probiotics are also available in the form of Supplements which are available in various forms, such as capsules, powders, and liquids. They contain specific strains of bacteria that can benefit gut health. How Do You Choose The Correct Probiotic? Strain Specificity: Different strains of probiotics have different effects. Consider your specific needs when choosing a probiotic supplement. CFU Count: CFU (colony-forming units) indicates the number of live bacteria in a dose. Storage: Some probiotics require refrigeration to maintain their potency. It’s important to consult with a healthcare professional for personalised advice on probiotic use, especially if you have any underlying health conditions.
