The world of health has always praised oats for their various nutritional values and pleasant taste. This cereal has also garnered significant attention for its potential benefits for gut health. For instance, did you know that oats are excellent sources of both prebiotic and probiotic compounds? Let’s try and understand the positive impact of oats on the gut microbiota, the powerhouse of your digestive system (and in fact your entire body).
Nutritional profile of oats
Oats are a rich source of essential nutrients that contribute to optimal health. They are primarily composed of carbohydrates, providing a steady energy source. The macronutrient profile also includes a moderate amount of protein and healthy fats.
Beyond macronutrients, oats are packed with micronutrients and antioxidants. They contain essential vitamins such as B vitamins, iron, and magnesium, which play vital roles in various bodily functions. Oats are a good source of antioxidants, including avenanthramides, which have been linked to various health benefits.
One of the most notable aspects of oats' nutritional profile is their high fiber content: 100 gm of oats contain over 10 gm of fiber! As we all know, fiber cannot be digested, but it plays a crucial role in gut health. Oats are particularly rich in a type of soluble fiber known as beta-glucan, which has been extensively studied for its beneficial effects on the digestive system. It forms a viscous gel in the digestive tract, slowing down the absorption of glucose and providing a feeling of fullness. Beta-glucan has been found to promote the growth of beneficial bacteria, such as Bifidobacteria and Lactobacilli, which play a crucial role in maintaining gut balance.
Dietary fiber is therefore essential for maintaining a healthy gut. It acts as a prebiotic, feeding beneficial bacteria in the gut and promoting their growth, which in turn helps to create a balanced gut microbiome, which is essential for optimal digestion, nutrient absorption, and immune function.
More benefits of oats for gut health
The health train doesn’t stop there; let’s take a look at the other ways that oats are good for gut health.
- Prebiotic effects: Oats act as a prebiotic, providing a food source for beneficial gut bacteria. These beneficial bacteria, such as Bifidobacteria and Lactobacilli, play a crucial role in maintaining gut balance and promoting optimal digestion. By nourishing these beneficial microorganisms, oats help to create a thriving and healthy gut microbiome.
- Enhancement of gut microbiota: A diverse gut microbiome has been associated with improved digestion, nutrient absorption, and immune function. Oats can help to increase the diversity of gut bacteria by providing a variety of nutrients that support the growth of different microbial species. This increased diversity can contribute to a more resilient and robust gut ecosystem.
- Improvement in bowel regularity: The high fiber content of oats, particularly beta-glucan, can help to improve bowel regularity. Fiber acts as a bulk-forming agent, adding volume to stool and promoting smooth passage through the digestive tract. This can help to prevent constipation and diarrhoea, ensuring healthy bowel movements.
- Reduce inflammation: Chronic inflammation in the gut has been linked to various digestive disorders, including irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Oats may help to reduce inflammation in the gut through several mechanisms. Beta-glucan in particular has been shown to have anti-inflammatory properties, and oats may also help to modulate the immune response in the gut, reducing inflammation and improving overall digestive health.
Types of oat-based foods beneficial for gut health
If you’re fully convinced that oatmeal is great for your gut but aren’t sure how to consume it in daily life, here are some options for you!
- Oatmeal: The most popular form of consuming oats, oatmeal is a classic breakfast choice that is rich in fiber and nutrients. It is a versatile food that can be enjoyed in many different ways. You can opt for plain oatmeal and add your own toppings, such as fresh fruits, nuts, seeds, or a drizzle of honey. For a savoury twist, try adding chopped vegetables, Indian spices, and herbs instead. Oatmeal can sometimes be highly processed, so do take precautions and go through the nutrition labels on whatever oatmeal products you buy.
- Granola: Granola is a mixture of oats, nuts, seeds, and sweeteners, sometimes found in bar form as a quick pick-me-up. Granola can be a convenient and nutritious snack option that can be enjoyed on its own or with yoghurt, milk, or fruit. However, as with oatmeal, granola can sometimes be advertised as a healthy alternative but can also contain excessive sugars and fats. Look for granolas that are low in added sugars and high in fiber. Even better, consider making your own granola at home to customise the ingredients and control the sweetness.
- Oat bran: Oat bran is a type of oat that is rich in fiber and soluble fiber, which can help to improve gut health. It can be added to smoothies, yoghurt, or baked goods to increase your fiber intake. Oat bran can also be used as a topping for oatmeal or as a binder in homemade energy bars.
- Oat-based smoothies and oat milk: Smoothies are a quick and easy way to incorporate oats into your diet. You can combine oats with fruits, vegetables, and other healthy ingredients to create a nutritious and satisfying drink. For a gut-friendly smoothie, you can also try combining oats with fruits and leafy vegetables like spinach.
- Oat milk: Oat milk is also an on-the-rise beverage for those who’d like to switch to plant-based milks for their intake! It contains no dairy and is made entirely from the oats themselves, and can be used to make lactose-free tea or coffee, ensuring that you get the best of both worlds.
- Oat-based breads and snacks: Many grocery stores now carry oat-based breads and snacks. These products are a great option for those who want to increase their fiber intake while enjoying their favourite foods. Look for products that are made with whole/rolled oats and have minimal added sugars.
