Health Benefits of Keto Shrimp Ceviche

Ceviche is a marinated seafood-based dish with Mexican, Caribbean, and South American variations. Famous for its acidic marinade and pops of color and flavor, ceviche recipes vary from using chunks of raw white fish to cooked shrimp and octopus.

There are hundreds of ceviche recipes, but the main components stay the same: every dish is fresh, acidic, and makes seafood the star of the dish.

If you’re not a fan of shrimp, feel free to use fresh, raw white fish or cooked octopus in the same citrus marinade. Just make sure — whatever protein you use — that it’s fresh. Now, on to some of the main health benefits of this fresh shrimp ceviche.

#1. An Immune System Boost

Avocados, lemons, and limes are high in vitamin C — a powerful antioxidant that can help keep your immune system strong and ward off illness[*].

Cucumbers, although made of almost 90% water, also contain immune-boosting nutrients like vitamin A, vitamin C, folic acid, and silica[*].

Onions are a known immune-strengthening food that include selenium, zinc, and vitamin C. Onions are also an excellent source of quercetin, a potent antioxidant and antiviral compound[*].

#2. Antioxidants Help Fight Free Radicals And Reduce Inflammation

This recipe is packed with antioxidant-rich ingredients, from the avocados to the tomatoes and onion.

The more antioxidants you consume, the more you’re battling free radical oxidation — a natural process that can damage cells, DNA, and protein molecules in your body.

And when you lower free radical damage, you’re naturally reducing inflammation — which is responsible for nearly every chronic disease[*].

Avocados are rich in carotenoids, antioxidants best known for supporting eye health[*]. Not only that — the fat in avocados actually helps your body absorb fat-soluble nutrients like vitamins A, D, E, K, and antioxidants like carotenoids from your food.

Quercetin — which you can find in onions and cilantro — may also prevent free radical damage caused reduce inflammation[*].

#3. Mood-Boosting Nutrients

There are several different ways that nutrient-dense foods may help support brain health and boost your mood.

But the biggest connection between food and mood is immunity and inflammation. Inflammation and a compromised immune system may be linked to certain types of depression[*].

So, it stands to reason that by keeping your immune system strong and inflammation down, your mood can benefit as well.

Avocados are rich in monounsaturated fatty acids (MUFAs), good fats that are linked to lower levels of inflammation, depression, and heart disease[*].

Avocados are also high in dietary fiber, which was found to be inversely related to symptoms of depression in one study[*].

Traditional ceviche sometimes contains sugary orange juice and comes with corn chips or plantain chips. You can keep this shrimp ceviche keto-friendly by subbing orange juice for a lemon or lime citrus base and using crunchy butter lettuce, cucumbers, or carrots in place of tortilla chips.

The other option, of course, is to simply eat your shrimp ceviche with a spoon. It’s that good.

Plus, total prep time and cook time are minimal — so you can even make this refreshing dish when you’re pressed for time.

  1. Um. . . . the first ingredient is 1 lb cooked, peeled, deveined, and chopped raw shrimp. Am I the only one seeing a problem right off the bat?

  2. Delish. I kept the avocado out and served the ceviche with fresh guacamole and keto tortilla chips. Perfect.

  3. Could you tell me the amount of net carbs in this recipe and also how do you figure net carbs from just carbs?

    1. This has 4 net carbs, Gabriela. You can get the net carbs by subtracting the fiber from the total carbs.

  4. This has been marinating overnight and the shrimp is still grey. It’s pink in your photo. Any idea why? I didn’t slump on the citrus – even added a little extra.

    1. The citric acid in the citrus breaks down the proteins making the shrimp pink. You may try adding lime/lemon and cover it up and refrigerate. The prepping time will depend on the size of the shrimp @Gabby

  5. In the nutrition facts it says 1 serving, What is the serving size 1 cup, or how many ounces? Or the entire recipe is 1 serving which I could eat I love ceviche thanks
