Avocados are rich in healthy fats, fiber, and nutrients, but for some people, mixing them with certain foods or medications can lead to unwanted interactions.
Here’s what you should know to stay safe and balanced.

Vitamin K and blood-thinning medications

Avocados contain moderate amounts of vitamin K, which can interfere with the effects of blood thinners such as warfarin.
Maintaining a consistent vitamin K intake is essential for safe and effective treatment.
Combining avocados with other vitamin K-rich foods

If you take warfarin, avoid eating avocados along with high–vitamin K vegetables such as spinach, kale, collard greens, and turnip greens.
This combination may alter your medication’s effectiveness.

Tyramine in overripe avocados

Overripe avocados contain tyramine, a compound that can trigger dangerous spikes in blood pressure in people taking MAO inhibitors or certain antibiotics such as linezolid.
High-tyramine foods to avoid with avocados

When eating avocados, avoid combining them with other tyramine-rich foods such as aged cheeses, red wine, coffee, fermented products, and smoked meats.
Too much potassium can be risky

Each avocado contains roughly 700 milligrams of potassium.
For individuals with kidney disease or those taking blood pressure medications such as ACE inhibitors or angiotensin II receptor blockers, excessive potassium can pose health risks.

High-potassium foods to watch

Foods like potatoes with skin, bananas, spinach, lentils, and fish such as salmon and trout are also high in potassium and should be eaten in moderation when combined with avocados.
Avocados and supplements

Pairing avocados with supplements that contain vitamin K or potassium can amplify their effects and disrupt balance.
Always talk to your healthcare provider before adjusting your diet.
Refined grains

While not harmful, eating avocados with refined grains such as white bread, white rice, or pasta offers less nutritional benefit.

Replace refined grains with whole options like oats, buckwheat, brown rice, or rye to make the most of the avocado’s healthy nutrients.
