Love Your Guts: Prebiotics and Probiotics – A Two-Part Series, Part 1: Prebiotics

-

 

Your gut is home to about 100 trillion microorganisms, primarily bacteria. Keeping the balance between good and bad bacteria is essential, and prebiotics can help ensure that the good bacteria have the nourishment they need to survive.

When it comes to gut health, I’m sure most of us have heard of probiotics—the helpful bacteria that does wonders for our digestive system. But have you ever stopped to think about prebiotics and why they matter too? These small, but mighty little microbes play a crucial role in supporting our gut health. They have the ability to enhance your gut microbiome, support digestion, and promote overall health. 

What Are Prebiotics? Breaking Down the Science 

Prebiotics are non-digestible food ingredients that nourish the good bacteria in your gut. Unlike probiotics, which are live microorganisms, prebiotics are found in certain foods and help the beneficial bacteria thrive and enhance the growth of your gut’s microbiome. Think of them as the food that keeps your gut's good guys strong and healthy.

The Role of Prebiotics in Gut Health

Prebiotics play a critical role in maintaining a balanced gut microbiota. By feeding good bacteria, they help to inhibit the growth of harmful microorganisms, creating a healthier environment in your gastrointestinal tract.

When prebiotics undergo fermentation in the gut, they stimulate the proliferation of beneficial bacteria, such as Bifidobacterium and Lactobacillus. This fermentation process also leads to the production of short-chain fatty acids (SCFAs), which are vital for the proper functioning of the intestines.

Why Prebiotics Matter

So, why should you care about prebiotics? Here’s why:

• Fuel for Good Bacteria: Prebiotics act as food for beneficial gut bacteria, helping them flourish while keeping harmful bacteria in check. This balance is essential for a healthy digestive system.

• Fermentation Benefits: When prebiotics are fermented in your gut, they stimulate the growth of friendly bacteria like Bifidobacterium and Lactobacillus. This process also produces short-chain fatty acids (SCFAs), which are vital for maintaining intestinal health.

Incorporating prebiotics into your diet can offer a range of health benefits:

1. Better Gut Health: Regularly eating prebiotics can improve the diversity and balance of your gut microbiome.

2. Nutrient Boost: They enhance the absorption of important nutrients, like calcium, which is crucial for bone health.

3. Blood Sugar Regulation: Prebiotics can help keep your blood sugar levels stable, making them a great addition to a balanced diet.

4. Immune Support: By strengthening your gut microbiome, prebiotics can bolster your immune system, helping you fend off infections.

5. Potential Cancer Protection: Some research suggests that prebiotics may reduce the risk of colorectal cancer—definitely a reason to include them in your meals!

Ways to Incorporate Prebiotics into Daily Diet

Boosting your prebiotic intake is very simple. Here’s how you can add them into your daily diet:

• Garlic: Add minced garlic to sautéed vegetables, soups, or marinades for an extra flavor kick.

• Onions: Use onions as a base for stir-fries, salads, or as a flavorful addition to sandwiches and wraps.

• Bananas: Enjoy bananas as a quick snack, blend them into smoothies, or add slices to your morning oatmeal or yogurt.

• Asparagus: Roast asparagus with olive oil and herbs as a side dish or toss it into salads and grain bowls.

• Artichokes: Steam artichokes as a snack or dip, or add artichoke hearts to salads and pasta dishes.

• Whole Grains: Incorporate whole grains like oats, quinoa, and whole wheat bread into your meals. Try oatmeal for breakfast, whole grain sandwiches for lunch, or a hearty grain bowl for dinner.

With these easy additions to your meals, you can enjoy the benefits of prebiotics making your diet its own super food. 



Prebiotics may not get as much attention as probiotics, but they are essential for a healthy gut. By adding prebiotic-rich foods to your diet, you can support your gut microbiome and enjoy a health benefits, including better digestive health. Stay tuned for part two coming soon, about probiotics, and discover how simple dietary choices can lead to huge changes in your overall well-being!

Do you struggle with pre and post exercise nutrition?

What should i eat before and after a workout? First things first…carbohydrates, proteins and fats are important for the body before  and after exercise. Exercising muscle preferentially uses carbohydrates from stored glycogen, but fats are also an important fuel source for energy production during exercise. Fats and carbohydrates are the two major fuel sources during exercise. Fats must be translocated and broken down from their storage form before they are used. Typically there is enough carbohydrate stored as muscle glycogen for exercise but as muscle glycogen stores decline, the skeletal muscle will then use some amino acids (basic components of all protein). More specifically, the amino acid leucine is used for energy.              It is important to consume an adequate amount of carbohydrates exercise to delay fatigue and minimize gastrointestinal distress. It is also important to consume enough fluids to prev...

Child Malnutrition

New approach to childhood malnutrition may reduce relapses, deaths http://www.sciencedaily.com/releases/2015/02/150211124024.htm               Moderate acute malnutrition is experienced by 35 million children worldwide. A new study led by researchers from Washington University School of Medicine in St. Louis has suggested that feeding children until they have met target measures of arm circumference and weight may be more important than a set 12 week feeding time. However, researchers have found that the current targets, set by the World Health Organization (WHO) may not be sufficient and raising these targets slightly could significantly reduce the risk of relapse in malnourished children; a condition that has a 37% relapse rate. The study took place in rural Malawi and was comprised of 2,349 moderately malnourished children aged 6 months to 5 years old. Children were evaluated 12 months after treatment; 1,967 rec...
