What I Frequently Notice During Community Nutrition Programs?

During my community health and nutrition awareness including family counseling in Odisha, I have observed that people are complaining about the bloating, irregular bowel movements, acidity, feeling heaviness after every meal.

Once, one office worker shared his experience about his frequent travel and irregular meal time that were affecting his digestion process. So, after including the curd, local fruits, homemade cooked foods, he gradually improved the eating habits and now lowered the digestive issues.

During a community nutrition discussion, one office worker shared that frequent travel and irregular meals were affecting his digestion. After gradually including curd, fruits, oats and more home-cooked meals, he noticed better eating habits and less digestive discomfort.

Many of them search the expensive digestive supplements to get remedy, but their diet lack just simple foods like curd, fruits, oats, fiber-rich vegetables.

In several situations, digestive disease is not the issue but the imbalance food choices, meal timing, proper hydration and lack of physical activity.

Such observation strikes my mind that gut health can be improved by just simple lifestyle habits not the complicated & costly alternative.

A Family Habit That Improved Digestion Naturally:

During my nutrition awareness sessions, a mother informed that her two school going children are frequently complaining about stomach pain including irregular bowel habits.

First, she thought that the issue is due to the outside fast food. But, after discussion in the mean time she realized the main cause like skipping of breakfast and giving packaged snacks.

The family gradually provided locally available fruits like banana, homemade curd, oats to their children. Within a few months of such practice the children were in a habit of good food with much less digestive issues.

This example may not be suitable for all children as they are different from each other, but simple food habits may influence the better digestion process.

These gut-supporting foods are part of functional food benefits, which provide additional health advantages beyond basic nutrition.

1. Yogurt

Yogurt contains live beneficial bacteria that support digestion and immune function. Fiber supports a healthy digestive system and could help enhance the body’s immunity. Choose regular yogurt that is not sweetened and contains active or live cultures such as those from Lactobacillus and Bifidobacterium. Use it as the liquid in your smoothies, mix it with other ingredients for sauces or eat it with fresh fruit and nuts.

2. Kefir

Kefir contains a wider variety of bacterial strains in “Kefir” rather than “Yogurt”. Yogurt is filled with useful yeasts and bacteria that settle in the gut, combat inflammation and help some people with lactose intolerance digest the milk sugar. You can consume it without additions, make a smoothie with it or pour it over granola.

3. Sauerkraut

This food is both rich in probiotics and fiber. Consequently, the stomach turns out to be a more hospitable habitat to good bacteria and a worse habitat to bad germs. Add it to your favorite sandwiches, salads or use it as a spicy side dish.

4. Kimchi

The Korean dish kimchi is a spicy vegetable that is often prepared from napa cabbage and radish. Probiotics and antioxidants may support gut health. It also helps to lower the inflammation. We may eat with rice, add to eggs or flavor your rice and grain bowls using this.

5. Bone Broth

First step is to simmer the bones & tissues of animals in water, so that it will release gelatin, collagen & amino acids. They may support the gut lining in the gut, help with inflammation and improve digestion. Dip or pour it warm, boil soups and stews with it or cook your rice and other grains in it for an extra kick of taste.

6. Garlic

It aids in boosting the development of useful bacteria found in the digestive tract of your body. It also contains properties that protect against microbes and fungi. Place garlic in your stir fries, soups, roasted vegetables or you can mince it into salad dressings.

Many gut-friendly foods also act as anti-inflammatory foods, helping reduce digestive irritation and support healing.

7. Onions

Just as garlic, onions are high in inulin which is a source of prebiotics for beneficial bacteria. One of the ingredients is quercetin, known for decreasing inflammation and improving your immunity. Saute some vegetables or try roasting, grilling or eating them raw in your favorite salad or salsa.

8. Bananas

If you consume green bananas, you get resistant starch that promotes healthy gut bacteria. Their presence improves bowel movements and is gentle for the stomach. You can eat them with pleasure so that they can be combined with some beverage, or you can use some to mix a shake, or you can add them to your cereal.

A healthy gut also supports endocrine function, and certain foods that balance hormones can further enhance overall well-being.

9. Apples

Pectin that is a form of fiber in apples acts as a prebiotic. Eating foods with pectin provides nutrients to advantageous bacteria in the gut and support good digestion. In addition, apples have polyphenols that soothe the lining of your digestive tract. 

10. Oats

The beta glucan in oats is a type of soluble fiber that contributes to the healthy growth of your gut bacteria and enhances the lining of your gut. They contribute to a reduction in cholesterol and in helping to maintain healthy blood sugar. We can prepare as oatmeal, bake with it or mix in the morning for quick overnight oats

My Observation as a Public Health Professional

I have observed from my public health career that many people focus on treatment only after the digestive concerns appear.

The simple daily habits like eating fiber rich foods, physical workout, drinking recommended quantity of water, adding fermented foods may be able to lower the digestive issues. I have learnt these from many families were are already in a such good habits.

You shouldn’t think that only one food will beneficial for gut health, but the food pattern is the key.

So, to overcome the problem, the following step can be followed:

• Eat a variety of whole, fiber-rich foods
• Include natural probiotics like yogurt or kefir
• Stay consistent with your habits

Just by choosing the right choice like adding oats in your breakfast or including garlic in your meals, associated with the improvements in gut health naturally in due time.

You are not supposed to take all the foods at a time or to maintain a complicated lifestyle, but just start with only one or two foods from the suggested list.

Because, if your gut is healthy, starting from energy to focus will improve gradually.

Improving gut health is one of the key strategies for strengthening the immune system naturally.
