Why we need protein!

We need protein because all the tissues and organs in our body require it. The muscles, bones, blood, nerves, skin, etc. are made of protein.

Protein was first named 175 years ago after the Greek word proteios (“of prime importance”)

Personal Nutrition 10th Edition

Recommended amounts of protein for portion control should be based on desired weight and calculated at 0.8 grams per kg of body weight. (2.2 lbs). Which really isn’t much. Balancing your meals with 1/4 of your plate protein, as shown on a portion control plate, will absolutely get you there.

Protein is essential for:

  • Growth, maintenance and repair of body tissues.
  • Building structures like skin, hair, muscle, bones, etc.
  • Regulate enzymes.
  • Send messages as hormones.
  • Fight substances as antibodies.
  • Maintain fluid balance.
  • Maintain acid base balance.
  • Transport nutrients.
  • Provide energy.

  1. I don’t know why, but I can’t just leave a recipe alone. I added 2 TBsp Chia seeds, 1/4 cup almond milk and 1/4 cup dark chocolate chips in the mix, then drizzled melted 1/4 cup dark chocolate chips on top. I cooked mine for about 20 minutes. Thankfully, my recipe builder lets me change from servings to weighted measurements for how much I ate.

  2. Hi I hope this makes sense, but I was wondering how to measure out the protein for each bar? With the protein powder

    1. Hi Jai
      You would just mix all the ingredients together for the whole recipe, and then form a big square or rectangle, and cut it into four bars equally.
      This way, each bar has 11 grams of the protein equally.

  3. Quick question: is the 142 kcal per bar or for 4 bars/balls? The bottom nutrition facts is different then what’s stated at the top for calorie count. One says the serving is 4 bars and the other one says 1 bar. Thanks for the clarification 🙂

    1. Shannon, thanks for having me revisit this. it was one of my first recipes, and actually, neither looks right now that I’m revisiting it.. but that was supposed to be Per bar! The true calories should be 121 calories per bar. I’ll fix it!
      For the full recipe it would be
      1 scoop protein powder 140 calories
      1/2 cup dry oats 150 calories
      2 tbsp peanut butter 180 calories
      2 tbsp milk 15 calories
      485 calories total or 97 per bar.
