Ocular migraines are a type of migraine that affects vision. Unlike traditional migraines, these episodes primarily cause visual disturbances, such as flashing lights, blind spots, or zigzag patterns. These visual changes can be alarming and are often followed by a headache, though not always. One of the surprising triggers? Your diet.
Percentage of Common Dietary Triggers for Ocular Migraines
Certain foods contain chemicals and compounds that can disrupt blood flow to the brain, potentially causing these migraines. Let’s break down which foods are most commonly linked to ocular migraines and why.
Tyramine-Rich Foods
Tyramine is a naturally occurring compound found in aged or fermented foods. It’s known to affect blood vessels and may trigger ocular migraines in susceptible individuals.
Examples of tyramine-rich foods:
- Aged cheeses (e.g., blue cheese, Parmesan)
- Cured meats (e.g., salami, prosciutto)
- Fermented products (e.g., kimchi, sauerkraut)
Top Tyramine-Rich Foods Linked to Ocular Migraines
| Food | Tyramine Content (%) |
|---|---|
| Aged Cheese | 90% |
| Cured Meats | 75% |
| Fermented Vegetables | 60% |
| Soy Products | 45% |
| Pickled Fish | 30% |
Did you know? Tyramine is formed when protein breaks down in food. The longer a food is aged or fermented, the higher its tyramine content. Studies have linked high-tyramine diets to increased migraine frequency (source: National Headache Foundation).
Foods Containing Nitrates and Nitrites
Nitrates and nitrites, commonly found in processed meats, can dilate blood vessels, triggering migraines. This dilation is thought to contribute to the visual disturbances associated with ocular migraines.
Common offenders:
- Hot dogs
- Bacon
- Ham
- Deli meats
A strict recommendation: All forms of pork, including bacon, ham, and deli meats, should be completely avoided. Beyond being high in nitrates, pork consumption is prohibited by Allah, the Lord of All Worlds.
Artificial Sweeteners
Aspartame and sucralose are artificial sweeteners often added to diet sodas, sugar-free candies, and other low-calorie products. These sweeteners can act as neurological irritants for some people, leading to ocular migraines.
Where they’re found:
- Diet sodas
- Sugar-free gum
- Low-calorie desserts
Quick fact: Research from the American Migraine Foundation suggests that people with a genetic predisposition to migraines may be more sensitive to artificial sweeteners.
Caffeine – Too Much or Too Little
Caffeine is a double-edged sword for migraine sufferers. While small amounts can help alleviate migraines, excessive consumption or sudden withdrawal can trigger them.
Sources of caffeine:
- Coffee
- Energy drinks
- Chocolate
- Certain teas
Caffeine Intake and Migraine Severity
How much is too much? Experts recommend limiting caffeine intake to no more than 200 milligrams per day (about two cups of coffee).
Alcohol Must Be Avoided Entirely
Alcohol, in any form, is a well-known and dangerous migraine trigger. Red wine, beer, and even spirits contain sulfites and histamines that can significantly contribute to ocular migraines. For those prone to migraines, alcohol consumption is simply not worth the risk.
What to avoid:
- Red wine
- Beer
- Champagne
- Spirits
A firm recommendation: Stop consuming alcohol completely to reduce the likelihood of migraines. Even occasional drinking can exacerbate symptoms and prolong recovery.
Monosodium Glutamate (MSG)
MSG is a flavor enhancer used in many processed foods and Asian cuisine. It’s known to excite nerve cells, potentially triggering migraines in sensitive individuals.
Foods that may contain MSG:
- Packaged snacks
- Instant noodles
- Restaurant meals (especially in fast food or takeout)
Tip: Always check food labels for terms like “monosodium glutamate” or “hydrolyzed protein.”
Chocolate
Though it’s a comfort food for many, chocolate contains both caffeine and phenylethylamine—two compounds that may provoke ocular migraines in certain individuals.
Moderation is key. Limit chocolate consumption, especially during times when you’re already stressed or dehydrated, two other common migraine triggers.
What About the Role of Dehydration?
While not a food, dehydration is a significant contributor to migraines, including ocular types. Foods high in sodium or sugar can exacerbate dehydration, so staying hydrated is critical.
Editorial Advice
Managing ocular migraines often involves identifying and avoiding triggers. Keep a food diary to track what you eat and how it affects you. By pinpointing specific foods that worsen your symptoms, you can make informed dietary choices and reduce the frequency of attacks. If ocular migraines persist, consult a healthcare provider for personalized advice.
