What are probiotics?
Probiotics are live bacteria and yeasts that are beneficial for our health, particularly for our gut. These microorganisms, when consumed in adequate amounts, can provide numerous advantages for our overall well-being.
Definition of probiotics
The World Health Organisation (WHO) defines probiotics as live microorganisms that, when given in sufficient amounts, benefit the host’s health. They can be found naturally in certain foods or can be taken as dietary supplements.
Types of probiotics
There are various types of probiotics that can be beneficial for gut health. The most common types include Lactobacillus and Bifidobacterium, which are both genera of bacteria. These probiotics are commonly found in fermented foods such as yoghurt and sauerkraut. Another commonly used probiotic is Saccharomyces boulardii, a yeast that can also provide health benefits. Each type of probiotic has unique characteristics and may offer specific advantages for gut health.
Benefits of probiotics for gut health
Probiotics play a crucial role in maintaining a healthy gut. They offer several benefits that contribute to improved digestion, a strengthened immune system, prevention of gastrointestinal infections, and reduced symptoms of gastrointestinal disorders.
Improvement of digestion
Probiotics aid in the digestion process by promoting the breakdown of food and the absorption of nutrients. They enhance the production of digestive enzymes, which help in the breakdown of complex substances, making it easier for the body to absorb nutrients. Probiotics also assist in regulating bowel movements and preventing common digestive issues such as constipation and diarrhoea. By supporting a healthy gut environment, probiotics can improve overall digestion and promote better nutrient absorption.
Strengthening of the immune system
The immune system plays a crucial role in protecting our bodies from harmful pathogens. Probiotics have been found to have a positive impact on immune function. They stimulate the production of immune cells and enhance the activity of these cells, thus strengthening our immune response. Regular consumption of probiotics can help reduce the risk of infections and may even alleviate symptoms of allergies by improving immune function.
Prevention of gastrointestinal infections
Probiotics have been shown to have a protective effect against gastrointestinal infections. They work by inhibiting the growth and activity of harmful bacteria in the gut. Probiotics produce substances that create an unfavourable environment for pathogens, preventing them from adhering to the gut lining and causing infections. In particular, probiotics have been found to be effective in preventing traveller’s diarrhoea, a common condition experienced during trips to foreign countries.
Reduced symptoms of gastrointestinal disorders
For individuals with gastrointestinal disorders such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD), probiotics can offer relief from symptoms. Probiotics have been shown to regulate gut motility and reduce inflammation, both of which are key factors in these disorders. By restoring balance to the gut microbiota, probiotics can help alleviate symptoms such as abdominal pain, bloating, and irregular bowel movements.
Improvement of digestion
How probiotics aid in digestion
Probiotics contribute to improved digestion through various mechanisms. One key mechanism is their ability to break down complex carbohydrates and fibre, which are often difficult for the body to digest on its own. Probiotics produce enzymes that break down these substances into simpler forms, making them easier for the body to absorb. Additionally, probiotics promote the production of short-chain fatty acids (SCFAs) in the gut. SCFAs provide a source of energy for the cells lining the intestine, thus supporting their overall health and function.
Probiotics and absorption of nutrients
Probiotics play a crucial role in the absorption of nutrients from our diet. They help break down proteins, fats, and carbohydrates, making them more accessible for absorption in the small intestine. Furthermore, probiotics improve the integrity of the intestinal barrier, preventing the leakage of undigested food particles and harmful substances into the bloodstream. By enhancing nutrient absorption and maintaining gut barrier function, probiotics contribute to better overall digestion and nutrient utilization.
Strengthening of the immune system
Role of probiotics in immune function
Probiotics have a significant impact on immune function. They interact with immune cells in the gut, stimulating the production of cytokines, which are molecules that regulate immune responses. Probiotics also enhance the activity of natural killer cells, which play a vital role in fighting infections. By modulating immune responses, probiotics help improve our body’s ability to defend against pathogens and reduce the risk of infections.
Probiotics and prevention of allergies
Allergies occur when the immune system overreacts to harmless substances, such as pollen or certain foods. Probiotics have been found to have a preventive effect on allergies, especially in children. They help regulate immune responses, reducing the likelihood of developing allergies. Probiotics also promote the development of a healthy gut microbiota, which has been linked to a lower risk of allergic conditions. Regular consumption of probiotics, particularly during early childhood, may help prevent allergies and promote a healthier immune system.
Prevention of gastrointestinal infections
Mechanism of action against pathogens
Probiotics exert their protective effects against gastrointestinal infections through various mechanisms. One way they work is by producing antimicrobial substances that inhibit the growth of harmful bacteria. Probiotics also compete with pathogens for nutrients and adhesion sites in the gut, making it more challenging for pathogens to establish themselves and cause infections. Additionally, probiotics stimulate the production of mucus in the gut, creating a physical barrier that prevents pathogens from adhering to the gut lining. By employing these defence mechanisms, probiotics help prevent gastrointestinal infections.
Probiotics and prevention of traveller’s diarrhoea
Traveller’s diarrhoea is a common condition experienced by individuals traveling to foreign countries, often caused by consuming contaminated food or water. Probiotics have been found to be effective in preventing traveller’s diarrhoea. They help maintain a balanced gut microbiota and enhance the body’s ability to fight off pathogens. By taking probiotics before and during travel, individuals can reduce the risk of developing traveller’s diarrhoea and enjoy a healthier gut during their journey.
Reduced symptoms of gastrointestinal disorders
Probiotics and IBS
Irritable bowel syndrome (IBS) is a common gastrointestinal disorder characterized by symptoms such as abdominal pain, bloating, and changes in bowel movements. Probiotics have shown promising results in alleviating symptoms of IBS. They help regulate gut motility, reducing episodes of diarrhoea and constipation. Probiotics also have anti-inflammatory effects, which can help reduce gut inflammation commonly seen in individuals with IBS. Regular consumption of probiotics has been associated with symptom improvement and a better quality of life for individuals with IBS.
Probiotics and inflammatory bowel disease
Inflammatory bowel disease (IBD), which includes conditions like Crohn’s disease and ulcerative colitis, involves chronic inflammation of the digestive tract. Probiotics can play a beneficial role in managing symptoms and potentially reducing disease activity in individuals with IBD. They modulate the immune response, reducing inflammation in the gut. Probiotics also help restore the balance of the gut microbiota, which is often disrupted in individuals with IBD. By promoting a healthy gut environment, probiotics can help alleviate symptoms and improve the overall well-being of individuals with IBD.
