All foods have health benefits; however some foods when paired with certain medications can have interactions. These food-drug interactions that can affect bodily functions, e.g., spike blood pressure, dull one’s motor skills, etc.

Here are a few foods which may have interactions when consumed in combination with certain medicines:

1. Grape Fruit

Furanocoumarins a compound that is a natural part of plant’s defense mechanism – deactivates drugs and other foreign chemicals. This interacts with several classes of drugs and increases their availability leading to overdose, as these drugs can end up circulating in an active state for much longer. Some compounds present in grape fruit juice can block a drug from getting into the cells or keep it from getting out. – This may result in excessive or insufficient circulation in one’s bloodstream.

2. Kale

Kale is filled with vitamin K that is required for normal healing through blood clots. In cases of heart attacks, arterial blockage, heartbeat irregularities where prescribed usage of blood thinner like Warfarin is common, one has to be careful not to overdo it with Kale and cruciferous veggies like brussel-sprouts and broccoli. Warfarin’s job gets much harder with excess of vitamin K. Also compounds such as flavonoid that is found in berries can block detoxifying enzymes just like grapefruit furanocoumarins.

3. Bananas

Banana is high in potassium, an essential element for heartbeats and neurotransmitter movement. For people with high blood pressure especially who are on a class of drugs known as ACE inhibitors that is known to block the conversion of in-active molecules to one that powerfully constricts blood vessels. One of the side effects is buildup of potassium. Banana and Kale being rich in potassium worsen the situation. Excess potassium can harm heart functions as opposed to a little build up.

4. Cheese

Dairy products can interact with the absorption of many drugs. Some people are found to be allergic to dairy products too. If one is taking drugs like monoamineoxidase inhibitors, aged cheese should be totally avoided. Most often fermented, cured and aged cheese is packed in tyramine, a chemical that would cause blood vessels to narrow.
There are a few food items loaded with vitamins and healthy nutrients that interact complementarily with some medications too. One needs to be careful about the food intake and medications and see to that those medicines are not washed down with the wrong kind of foods.
