I have heard many times growing up that if your eyelid is twitching, it means you need more potassium in your diet, and therefore should eat more bananas.
A quick search online finds a variety of recommendations for treating a twitchy eyelid, including eating bananas. Many of these recommendations appear to originate from proponents of alternative medicine.

An example claim:
A nutrient found in potent amounts in bananas, potassium is an effective treatment for muscle spasms and other disorders. Potassium is considered an electrolyte that promotes the effective functioning of the cells, tissues and organs. Eating bananas regularly and taking a potassium supplement can help prevent and treat spasms of the eyes and other muscles.
Is there scientific, medical basis for any of the following claims:
- Insufficient Potassium in your diet can cause your eyelids to twitch.
- Insufficient Potassium in your diet can cause muscle spasms.
- Eating bananas provides your body with Potassium.
- Eating bananas will keep your eyelids from twitching (i.e. for any other reason than dietary Potassium).
- Eating bananas will prevent (or reduce) muscle spasms (i.e. for any other reason than dietary Potassium).
