Part 2: How fiber may help manage migraine episodes
I recently listened to an interview that mentioned increased fiber intake may lead to fewer migraine episodes. Intrigued by the idea of experiencing fewer migraine attacks, I made a note to research it. This article highlights what I discovered. I hope you find it valuable!
Migraine Reduction:
A 2023 cross-sectional study published in Frontiers found that every 10-gram-per-day increase in dietary fiber intake was associated with 11% lower prevalence of severe headache or migraine. While the strength of association varied by gender, race, and age, the overall results suggested that people who consumed more fiber reported fewer migraine attacks. 10 grams of fiber can be as simple as eating a cup of raspberries. Here's a chart of high-fiber foods. Current guidelines recommend a daily fiber intake between 25-38 grams, or 14 grams for every 1,000 calories.
Although this study doesn't prove that fiber itself reduces migraine, it adds to a growing body of research suggesting that high-fiber diets support overall health, influencing migraine. Factors other than fiber that may have played a role in this study include minerals, vitamins, and antioxidants available in fiber-rich foods, individual environment, weather changes, specific foods eaten, and medications, among others.
The Role of Diet:
What you consume matters. Several dietary patterns, such as the Mediterranean, DASH, MedDASH, MIND, and ketogenic diets, have been studied for their effects on migraine. While the evidence varies in strength, these diets emphasize nutrient-dense whole foods and have shown hope for reducing migraine frequency and/or severity in some people.
Whole foods contain fiber, water, minerals, vitamins, antioxidants, and protein that support the body. These foods are grown from the land or minimally processed. Ultra-processed foods are often higher in refined carbohydrates, added sugars, sodium, and unhealthy fats while providing less fiber and fewer nutrients than minimally processed whole foods.
Reducing processed foods lets in fewer ingredients, making it simpler to identify problem foods. Many people are aware of foods that could trigger migraine attacks, such as chocolate, alcohol, artificial sweeteners, while being unaware of foods that could reduce the frequency of migraine, such as legumes, fruit, and vegetables. Migraine varies by person, so be aware of how food makes you feel to learn your particular tolerances.
Why fiber may help:
Fiber is a prebiotic, feeding good bacteria in the microbiome and thereby influencing many body systems. A diverse, balanced gut microbiome is associated with many aspects of physical and mental health. Higher fiber intake is linked with a lower risk of conditions such as cardiovascular disease, type 2 diabetes, obesity, and depression. All that to say, fiber does a lot.
How to apply this to real life:
Learning how to support your body is important and applying it to your everyday life can be challenging. Create a plan and give yourself grace. Not every day will be perfect; it's not supposed to be. Perfection isn't real life, and we're applying this to real life. Every change counts.
Here are some ideas to start eating more fiber-rich foods:
Eat whole, natural foods often.
Reduce consumption of processed foods.
Be mindful of how you feel after different foods (track it, if necessary)
Stay hydrated
Read something nutrition-based once a week.
Add one new fiber-rich food per week.
Find recipes you enjoy
Recruit an accountability partner
Increase fiber gradually and drink plenty of water to reduce bloating and digestive discomfort while your body adjusts. Slowly evolving eating habits can also help create long-term change. All bodies are different; please speak with your physician about any medical concerns you may have.
