Do you often have stomach problems? Do you struggle with problems like feeling full, gas, bloating, or constipation? Sometimes we think these are normal things. But the reason behind these discomforts is some of the foods we eat. Today, we are going to talk about a special diet that will help you identify and control such foods and give your digestive system relief.
Simply put, what are FODMAPs?
The word FODMAP may sound a bit complicated when you hear it. But it's actually quite simple. FODMAP is an acronym that stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols .
Don't think about these strange words. Simply put, these are several types of fermentable carbohydrates that are difficult for our intestines to digest easily.
Let's explain this a little more:
- Fermentable: This means that the bacteria in our large intestine take these foods and "eat" them, producing gas in the process. This is called fermentation.
- Oligosaccharides: These are often found in foods like wheat, onions, garlic, beans, and lentils. Some people may experience stomach discomfort after eating bread or lentils because of these. Some people think they have a gluten intolerance, but the real cause may be the FODMAPs found in wheat.
- Disaccharides: The main one in this group is lactose. This is the type of sugar found in milk and dairy products. Many people experience stomach problems when they drink milk because this lactose is difficult to digest.
- Monosaccharides: This refers to fructose. That is, the sugar found in fruits. But not all fruits, and some fruits contain high levels of fructose, which can cause problems.
- Polyols: These are called sugar alcohols. They are often used as artificial sweeteners. They also occur naturally in some fruits.
Why are these FODMAPs difficult to digest?
This is how it works. The food we eat is normally digested and absorbed by the body in our small intestine. However, these types of carbohydrates called FODMAPs are not broken down and absorbed that easily.
So, when they can't be absorbed, the small intestine pulls in more water to push them down more easily. Then these FODMAPs move on to the large intestine.
Imagine, this is like a party for our friendly bacteria in the large intestine. They eat these indigestible FODMAPs and start the fermentation process. HereAs a result, gas is produced.
It is when the excess water drawn from the small intestine and this gas combine that symptoms such as bloating, stomach pain, bloating, diarrhea, or sometimes constipation occur.
So are FODMAPs bad for everyone?
Not at all. In fact, FODMAPs are found in many healthy foods. For example, they are found in vegetables, fruits, and grains. They are good food for the good bacteria in our gut. That means they are necessary for a healthy digestive system.
However, some people have very sensitive digestive systems. Especially those with conditions like Irritable Bowel Syndrome (IBS) or Small Intestinal Bacterial Overgrowth (SIBO) , who cannot tolerate the amount of gas and water produced by these FODMAPs. These symptoms are more common in these people. The Low FODMAP Diet is primarily recommended for such people.
How to do the Low FODMAP Diet?
This is not something you do all at once. It's like detective work. It's an investigation to find out exactly what foods are causing you problems. There are three main stages to this.
1. Elimination Phase
This is the first and most difficult phase. During this time, you will need to completely eliminate all high-FODMAP foods. This usually takes about 2 to 6 weeks. During this time, your intestines will get a good rest and the discomfort will decrease.
2. Reintroduction Phase
Once your symptoms have significantly improved, we will start to reintroduce foods one by one, one by one. But this is done in a very planned manner. For example, one week you will try lactose (milk). The next week you will try fructose (a fruit). This way we can find out exactly which FODMAP group is causing you discomfort and how much of it you need to eat to feel uncomfortable.
3. Maintenance/Personalization Phase
Now that you know what you are sensitive to and what you are tolerant of, the next step is to create a healthy, long-term eating plan that is right for you, limiting only the foods you are sensitive to and including everything else. The goal is not to restrict foods, but to help you eat as varied a diet as possible.
What are FODMAP foods?
Here are some examples. You can get a complete list from your doctor or nutritionist.
| High-FODMAP Foods to Avoid | Low-FODMAP Foods That You Can Eat |
|---|---|
| Vegetables: Onions, garlic, beetroot, cabbage, cauliflower | Vegetables: Carrots, cucumbers, pumpkin, spinach, bean sprouts (in limited quantities) |
| Fruit: Apple, mango, watermelon, cherry, peach | Fruit: Bananas (underripe), grapes, strawberries, oranges, pineapple |
| Dairy foods: cow's milk, yogurt, ice cream, soft cheeses | Dairy foods: Lactose-free milk, hard cheeses, almond milk |
| Protein: lentils, chickpeas, beans, processed meats like sausages | Protein: Meat, fish, chicken, eggs, tofu |
| Grains: Foods made from wheat, barley, rye (bread, pasta) | Grains: Rice, Oats, Quinoa, Gluten-free bread |
Things to know before starting this diet
This is not a good thing to start alone. There are several reasons for that.
1. Seek medical advice: It is important to first determine whether your symptoms are due to a condition like IBS or another serious illness. Therefore, be sure to see your doctor. He or she can refer you to a qualified dietitian.
2. Plan: This is a bit of a painstaking task. So choose a time when you have free time and are not stressed. You cannot stop halfway through this diet. If you do, the whole experiment will fail.
3. Get ready:Before you start, eliminate high-FODMAP foods from your home, make a list of foods you can eat, and bring the necessary ingredients. This will make it easier to cook in a hurry.
The important thing is that this is not a lifelong diet. The ultimate goal is to help you eliminate unhealthy foods and reintroduce as many different foods as possible back into your diet.
This test won't work for everyone. It's possible that your symptoms aren't caused by FODMAPs. But that's not a problem. If that's the case, you can talk to your doctor and decide what to do next.
