Shellfish on keto? Top reasons why.

Do you like shellfish? Then you are in luck.

Shellfish is a great food, whether you are on the keto diet or not. It is one of the most nutrient dense foods out there.

When you are doing a healthy version of the keto diet, your body needs these nutrients to function properly. Shellfish are on the top of the list.

Let’s see what makes the shellfish so important.

Top nutrients in shellfish.

Shellfish have these following nutrients:

  • Iodine
  • Iron
  • Zinc
  • Selenium
  • Copper
  • DHA
  • B12

Let’s go through on why these nutrients are important.

* Iodine: Most of your iodine is stored in your thyroid, it is also in some of your organs. It is there to make thyroid hormones. It is really important for a growing child and pregnant women. Iodine has an influence on a child I.Q. and growth.

* Iron: If you have a deficiency of iron you can have a lot of problems, such as anemia, lack of growth and development, lack of carrying oxygen through your body. But having too much iron is also unhealthy. Shellfish has the great type of iron that your body needs.

*Zinc: Zinc is vitally important for many reasons like your immune system, skin, helping with testosterone and help with preventing Viruses and bacteria. Shellfish is loaded with Zinc.

*Selenium: This is also a very important trace mineral. It also very concentrated i the thyroid. Selenium acts like an anti-oxidant. It helps to protect against oxidation that are caused by free radicals. As you may or may not know, free radicals causes damage to cells, proteins, mitochondria and DNA.

*Copper: Copper is also a trace mineral. It is very good for the adrenals. Copper is also involved with collagen, ligaments and tendons. So Copper is also a very important mineral to eat. Copper paired together with Iron enables the body to form red blood cells. Copper helps maintain healthy bones, blood vessels, nerves and immune function. It also contributes to iron absorption.

*DHA: This is key for the brain, eye and heart. DHA is an omega-3 fatty acid. DHA is very important for the growth and size of your brain. DHA is also essential for a functional nervous system which includes the brain. Studies have show that people with Alzheimer’s disease have lower levels of DHA in their brains.

*Vitamin B12: If you are deficient in B12, not only can you experience anemia but you can also experience debilitating neurological problems that can become permanent. These neurological problems include: vision problems, memory loss, pins and needles (parasthesia). 

What kinds of shellfish are there?

There are many kinds of shellfish, and I love each one of them. My wife loves crab and lobster but not the other ones. You can easily make a nice crab or lobster salad with just some mayonnaise, mustard and black pepper. Put the salad on top of a bed of lettuce and enjoy with maybe a squeeze of lemon on top.

  • Crab
  • Lobster
  • Shrimp
  • Mussels
  • Oysters
  • Clams
  • Scallops

You can also dip the Shrimp, Lobster or Crab in a melted grass butter dip to get more benefits of the healthy fats.

Which food is the best if nutrient density is compared?

  1. Shellfish would be at the top of the list.
  2. Eggs are in the second place, because eggs almost every nutrient except vitamin C.
  3. Dark leafy greens would take the number 3 spot.
  4. Fish, just remember to get wild caught to get better quality omega-3.
  5. Beef liver is also a very nutrient dense food. I have an article on the top 3 organs meats here.


There are many more great foods out there but I just anted to make an article on shellfish not only because I love shellfish, but I also wanted to know if they were OK on the ketogenic lifestyle.

As I have discovered that they have way more benefits than I would have thought.

I’d you are concerned about the high amounts of cholesterol in these foods don’t be if you are on the keto diet. I would take it easy if you are not, because as we all know by now that fats and carbs do not combine well. Your body will always burn carbohydrates as fuel before fats, leaving them unused and stored within the body.

I really hopes that this articles serves you well, and if you have any questions or concerns please leave them in the comment section. I will answer back within a few days or sooner.
