If you’re tired of eating the same dishes all the time and want to switch things up, then this recipe is for you. It will make an otherwise boring day seem special, especially if you’ve never tried mussels before. 

This Keto Instant Pot Mussels dish contains special ingredients. The key one is a mussel. These cute little shellfish contain qualities that make them a superfood. It’s one of the best seafood for keto diet.

A 100-gram serving of raw mussels contains 86 calories, nearly 12 grams of protein, 2.24 grams of fat, 3.69 grams of carbs, and 20 different vitamins and minerals (1).

Mussels are a great source of omega 3 fatty acids, including EPA and DHA, and many essential amino acids. Research shows that eating mussels three times a week for two weeks as your primary protein source at lunchtime significantly improves your omega 3 index and whole blood EPA and DHA levels (2).

Omega 3 fatty acids that are derived from marine sources have been shown to reduce the risk of death from cardiovascular heart disease. It also lowers the risk of cardiovascular disease in general (3). Omega 3 fatty acids also help protect the brain against neurodegeneration (4). 

The other components in this recipe include lemon, which is a good source of vitamin C, folate and potassium, onions or shallots, which are high in protein, fiber, and micronutrients, including calcium, iron, magnesium, phosphorus, potassium, zinc, copper, folate, B vitamins, and vitamins A and C, and chili flakes, which have thermogenic properties to “heat up” your metabolism. 

You’ll also need garlic cloves, black pepper, butter, chicken broth, which has more than 19 easy-to-absorb, essential and nonessential amino acids that are needed to build protein and support digestive health and immune system support. Oh, yes, and white wine. It always couples well with seafood!
