My interview with Marty Kendall inspired me to talk about this and I think it is something everybody should think about when deciding on which proteins to use in your meals.Quality meat and seafood contain more protein per calorie and per gram especially when you consider bioavailability than any other foods.One of the main issues with plant protein is to get enough protein (to promote satiety, build muscle or avoid sarcopenia) without supplementing with processed protein powders. If you are following an exclusively plant-based diet, it will be much harder to absorb the protein you require without consuming excess calories and/or a massive volume of food! While you can get enough protein from broccoli, you will need to eat nearly 13 pounds of it to get 2000 calories to fuel you for the day!  If you can’t imagine yourself consuming that much broccoli, you could go for 1.3 pounds of cod with 630 calories and get the same amount of protein as the 13 lbs - 2000 calories worth of broccoli.  Focusing on leaner and more bioavailable protein sources will give you a much better chance of building and maintaining plenty of lean muscle mass. While there can be some benefits in consuming nutrient-dense plant-based foods, relying on them as your primary source of protein may be problematic if you don’t want to have to consume too many calories or don’t have the appetite to eat so much.The amino acid profile also differs between plant and animal-based foods.  Why is that important?  Amino acids play a role in almost every system throughout your body, including: Assisting in the creation and growth of muscles, connective tissue, and skin. Assisting in maintaining muscle tone and tissue strength. Healing and repair.Lysine is an amino acid that is plentiful in fish (e.g. halibut, haddock, shrimp and prawns) and meat (e.g. beef, chicken and turkey). It is an essential building block for all the other proteins in your body and plays a significant role in calcium absorption. Lysine is critical for muscle growth and is used to form carnitine, which helps you use fats for energy.  Inadequate lysine is associated with anemia, fatigue, poor concentration, loss of bone calcium, tiredness and infertility.  Proteins from animal sources (i.e. eggs, raw milk, meat, fish and poultry) provide the highest quality rating of food sources. This is primarily due to the ‘completeness’ of proteins from these sources.Not all proteins are created equal so be thoughtful when making a decision which ones you decide to eat your meals with.Thanks for listening and have a great day!Links:Watch Get Lean Eat Clean podcast video episodes on YouTube!https://www.21dayfastingchallenge.com/X3 Bar: Variable Resistance Technology allows for a full body workout in only 10 minutes! Use discount code "Save50" for $50 off your purchase!| Listen to the Get Lean Eat Clean Podcast |►iTunes | https://podcasts.apple.com/us/podcast/get-lean-eat-clean/id1540391210►Spotify | https://open.spotify.com/show/0QmJzYZsdV6tUNbDxaPJjS| Connect with Brian |►Website | https://www.briangryn.com►Instagram | https://www.instagram.com/bdgryn►Facebook | https://www.facebook.com/getleanandeatclean►Twitter | https://twitter.com/grynnerwinner
