Also, unlike other fast foods, they are healthy.

Egg Dishes with Nutrition Facts

While hard-boiled eggs have nutrition facts every health expert loves, you may not like to have them every day.

So, here are three other ways you can cherish eggs. But first, check their nutritional value.

  • Scrambled Egg

Creamy and soft scrambled eggs with a depth of flavor thanks to the butter make the perfect breakfast. Not only do your taste buds love it but your body finds it healthy too. 

That’s right. 

About a cup (135 grams) of scrambled eggs contain (2): 

  • 243 calories
  • 19 g fat 
  • 16 g protein 
  • 0.9 g carbohydrate (with 0.5 g sugar and 0 g of dietary fiber) 
  • 8.5 g saturated fat 
  • 487 mg cholesterol 
  • 261.90 mcg vitamin A 
  • 2.56 mcg vitamin D 
  • 2.20 mg iron
  • 72.90 mg calcium
  • 176 mg potassium

This serving of two eggs and one tablespoon of unsalted butter contains extensive amounts of electrolytes and crucial vitamins. These include potassium and vitamin A. 

Being rich in potassium makes scrambled eggs great for your blood pressure, nerve function, and muscle function, while Vitamin A helps improve vision and immunity.

Additionally, eggs, butter, or its replacement olive oil are all great keto-friendly foods. 

If you have ever tried the keto diet or are planning to, you may know the net carbs allowed on keto is less than 20g. With only 0.9 grams, scrambled eggs fit the keto diet easily. Just make sure you don’t overeat if you want to keep your body in ketosis.

  • Egg Yolk

A lot of people like to avoid the yellow part of the egg in their breakfast

But those who know that the egg yolk contains egg’s nutrients in a higher proportion like to make it a part of their regular diet. 

With small amounts of vitamins A, B-12, and D along with tryptophan, folate, and riboflavin, egg yolks are highly nourishing. 

  • Here’s the whole list of egg yolk nutrition facts in a 100-gram serving (3):
  • 322 calories
  • 26.5 g fat
  • 15.9 g protein
  • 3.59 g carbs (with 0.56 g of sugar and 0 g of dietary fiber)
  • 9.55 g total saturated fats
  • 1080 mg cholesterol
  • 129 mg calcium
  • 390 mg phosphorus
  • 109 mg potassium
  • 48 mg sodium

As you can see, egg yolk is also rich in electrolytes like calcium, phosphorus, and potassium. This makes it great for those following the keto diet as it helps avoid keto insomnia-like issues.

There’s one problem though. Egg yolk contains a high amount of cholesterol which can hamper your heart health. Make sure you don’t consume it regularly without consulting your doctor.

  • Egg Noodles

A basic recipe for egg noodles uses soya sauce, veggies, eggs, and of course, noodles. These make the Chinese dish quite healthy and delicious at the same time.

Did you know? A 100-gram serving of egg noodles contains (4): 

  • 138 calories
  • 2.07 g fat
  • 4.54 g protein
  • 25.2 g carbs (with 0.4 g of sugar and 1.2 g of dietary fiber)
  • 0.419 g total saturated fats
  • 29 mg cholesterol
  • 12 mg calcium
  • 76 mg phosphorus
  • 38 mg potassium
  • 5 mg sodium

The protein, carbs, and a good amount of electrolytes make it nourishing. This will help you prevent dehydration (due to electrolyte imbalance) and will give you energy throughout the day.

But if your body is in ketosis or you are looking to incorporate ketone drinks into your diet, egg noodles may not be a good dietary choice.

The main culprit here is the noodles. They are made of flour which significantly increases the proportion of carbohydrates in your meal. 

While these carbs may be healthy, they may throw you off ketosis if you don’t calculate the carbs right.

With quite low fat and more than 20 g of carbs, a 100-gram serving of egg noodles is not keto-friendly. If you want to have it during keto anyway, a spoon or two is what you can have at most.

Also, when compared to egg yolk or scrambled eggs, egg noodles have a low amount of electrolytes. So, they may not be as helpful against keto flu symptoms
