Ingredient Spotlight: Flaky White FishHere's an impressive list of health benefits associated with eating flaky white fish like halibut or cod.
- White fish lowers your risk of cardiovascular disease .
- It's incredibly high in protein (halibut, for example, can have upwards of 40g of protein per serving) 
- It contains absolutely no carbs!
- It's loaded with B vitamins, which help give you energy, keep the mitochondria in your cells healthy, and regulate your metabolism to help you keep burning calories!
- White fish contains more than 10 essential minerals that your body needs, like magnesium, phosphorus, and iron.
- It’s a good source of selenium, which is a mineral that's been shown to reduce your risk of cancer .
Is Pineapple Keto?
The short answer is yes—but only sometimes.
The longer answer is that fruits like pineapple offer health benefits you don't want to ignore, and shouldn't necessarily always be avoided on a ketogenic diet.
After all, fresh pineapple contains liberal amounts of vitamin C, along with several key minerals your body needs, like iron, magnesium, and manganese .
However, one cup of pineapple is a bit high in carbs. 21g of carbs per serving isn't that bad (an apple has more), but that's still a little less than half the amount you should eat each day to stay in ketosis.
The saying "everything in moderation" applies perfectly here. You'll get four servings for each cup of pineapple you make with this recipe, meaning you're actually only eating about 5g of carbs with this meal.
So as long as you don't overdo it, and make sure the carbs work for your daily intake, you'll be fine.
Feel free to work pineapple into your routine from time to time—especially when the fresh stuff goes on sale.
