Shellfish
All shellfish contain a high number of vitamins and minerals like copper and zinc and like all seafood, shellfish contain a large amount of omega 3. But for a keto dieter, you must be cautious as some shellfish may contain higher carb than expected. For 100 gm serving of shellfish, mussels contain higher net carb (7 gm), while shrimps and crabs contain no carbs. Frequent fish intake maintains mental health and helps in the prevention of some diseases like Alzheimer’s.
