Protein Quality: Plant vs Animal -Is One Better? - #HP-EVOO - Blog #84
Hi Everyone! Welcome back to another Friday blog! Today I wanted to take a look at protein. If you look at the nutrition content on a food label, you'll see the amount of total protein. This tells you very little about whether or not you are getting the essential amino acids required for optimal nutrition. There is a growing demand to require the list of amino acids content of foods to be on the label. Another consideration is the quality of protein - did it come from plants or animals? Was it wild-caught, grass-fed, regeneratively produced - or did it come from a standard feed lot? Is one better than the other? Let's delve in.
First, what is protein? Protein is the collective term we use for all the AAs (amino acids) - the building blocks of life. There are 20 human proteinogenic (geneticlly encoded) amino acids - and 2 additional amino acids (selenocysteine and pyrrolysine) that are "co-translationally" inserted into proteins. Nine of these are essential amino acids (EAAs) - with 1 EAA-dependent - Cysteine can only be synthesized from methionine. This means we MUST get these specific EAAs from our diet. Currently, no nutrition labels contain this information for us. How do you know if you are getting enough of each one. Do we need the same amount of each EAA, or are some more important?
- isoleucine - BCAA (branched chain amino acid)
- leucine - BCAA
- valine - BCAA
Did you know that roughly 80% of the plant-based protein in the U.S. and world comes from wheat?😮 Global production as of 2020 is roughly 763 million tons. Wheat is deficient in isoleucine, leucine, threonine, tryptophan and lysine. Corn is also lacking in EAAs, with lysine being the lowest or close to non-existent in both wheat and corn. This relates to so many things in the body - Structural protein deficiencies, aberrant metabolic signaling, poor brain function with low serotonin and tryptophan. Think of it this way - you need to build a 20-story building, but you don't have concrete for the foundation or any rebar for support. You are not going to have a sturdy building that can withstand rain, wind, elements... Our body is the same - we don't have the appropriate building blocks, we don't have a functioning, resilient body.
AAs are the building blocks for ALL your enzymes - they have jobs to perform - these are your working tools. They transport materials, attach things together and prevent things from going where they are not supposed to go. They are the structural proteins that build our tissues, antibodies, bones, teeth, hair, etc. If you want a strong and resilient body, you need to be paying attention to your EAAs! If your diet is lacking in tryptophan, for example, you can't make serotonin! It is also the precursor to melatonin - one of the 2 antioxidants used by your mitochondria. Being deficient in just this one AA can easily set you up for depression, sleep disturbances, low energy, mitochondrial dysfunction!
On top of this, as a nation we are meeting the bare minimum daily requirement for protein. Coupled with dietary protein that is deficient in EAAs, we have a nation of structurally and metabolically deficient humans. "For synthesis of new muscle protein, all the EAAs, along with the eleven non-essential amino acids (NEAAs) that can be produced in the body, must be present in adequate amounts. The branched-chain amino acids leucine, isoleucine and valine are three of the nine EAAs. Leucine is not only a precursor for muscle protein synthesis, but also may play a role as a regulator of intracellular signaling pathways that are involved in the process of protein synthesis." In this abstract, they report BCAAs alone are not enough to stimulate protein synthesis, so the claim by supplement manufacturers that taking BCAAs stimulate muscle synthesis is not valid. They also highlight the fact that new muscle synthesis can only happen postprandial (after eating) and ALL the AAs must be present - otherwise, AAs are stolen from existing muscle = no net gain in muscle tissue.
We now know that longevity is closely related to muscle mass. It is also clear that if you don’t develop your muscle mass early, it can “predestine” you to store fat on your organs - you become “skinny-fat” with VAT (visceral adipose tissue) later in life. Further, as we age, we can’t build new muscle tissue as readily as we could when we were 20. It takes MORE quality protein (that includes ALL the AAs) to make new muscle tissue. The current recommendation if you are >60 yo is 1.5-1.9g/Kg body weight - to prevent sarcopenia (muscle wasting/loss). This can be a challenge, particularly for elderly who are not eating as much. The smaller amount you eat, the higher the quality needs to be - just to meet the basic requirements. So, choosing high-quality complete protein that contains high levels of EAAs is key!
If you are vegetarian or vegan, it can be very difficult to do. A completely plant-based diet is exceptionally hard to do properly without losing precious muscle mass. Most vegans, especially, need to supplement - just to be able to get B12 - not to mention Further, you must consider the source of the protein and how it is processed. If you are talking powders, is it pea or whey protein powder? There is 8g protein in 1 C peas - roughly 15g per serving of pea protein powder. What about whey protein powder? Definitely more protein at 20-27g per serving. According to a warning from Harvard: “Protein powders are powdered forms of protein that come from plants (soybeans, peas, rice, potatoes, or hemp), eggs, or milk (casein or whey protein). The powders may include other ingredients such as added sugars, artificial flavoring, thickeners, vitamins, and minerals. The amount of protein per scoop can vary from 10 to 30 grams. Supplements used for building muscle contain relatively more protein, and supplements used for weight loss contain relatively less.”
It is not easy - even if you consume animal products. The animal must have eaten the right food - grasses and wild weeds - not grains!! This is another reason to choose grass-fed, sustainably raised beef, pastured chickens and eggs and wild-caught fish. These animals ate the right foods - so, their products are high in phytochemicals and polyphenols that have profound health promoting benefits - you know...the circle of life.
There are several benefits to consuming quality meat: optimal ω 6:3 ratio, higher in BCAA metabolites - signifying higher muscle protein content - higher in B vitamins as well as fat-soluble vitamins like retinol (active vitamin A) and vitamin E, minerals and up to 4x higher levels of CLA (conjugated linoleic acid) that promotes muscle gain as well as being anti-cancer and anti-obesity. Let’s compare grass-fed/finished beef to conventional feed-lot grain-finished beef:
Grass-fed/finished beef - particularly when allowed to roam and forage for wild plants - is sustainable and regenerative - has very little impact on global warming - high in ω 3s, full of vitamins, minerals, amazing antioxidants, anti-inflammatory phytochemicals and polyphenols that act as growth factors for beneficial bacteria - selectively inhibiting pathogens - enhancing absorption and stability of essential nutrients. It is lower in homocysteine, triglycerides and AGEs (advanced glycation end products).This helps to prevent chronic diseases such as cancer, CVD (cardiovascular disease), T2D (type 2 diabetes), HTN (hypertension), inflammation, infections, dementias and Alzheimer’s, Parkinson’s and other neurological diseases.
Grain-fed/finished beef is high in ω 6s - pro inflammatory, negatively affects glucose metabolism, increased collagen metabolites as well as markers of protein breakdown and increased homocysteine levels that increase risk of CVD. This "feedlot" red meat is the reason red meat got a bad rap. These animals are not "healthy" because they are not eating the right foods. Many are sick and given antibiotics. In fact, animals account for the majority of antibiotic usage. Further, it is NOT sustainable - NOT regenerative - VOID of essential nutrients - contributes to global warming primarily due to the grains, ground up animal parts and even skittles they are fed. However, fossil fuels and glyphosate are the biggest contributors.
So, how can we make sure we are getting what we need?
- Demand EAAs with levels be listed on food labels
- Increase your knowledge about whole protein sources
- Eat a variety of protein sources - due to different AA compositions and phytonutrient levels - choose high-quality plant and animal for optimal nutrition!
- Pastured organic eggs contain all 20 AAs, including the EAAs, all the fat-soluble vitamins, tons of polyphenols and phytonutrients, have an ideal 3:1 ω 6:3 ratio of DHA and EPA.
- Spirulina -(50-70% protein) a cyanobacterium (blue-green algae) - also contains all 9 EAAs, an ideal 1.5:1 ω 6:3 ratio with high EPA and ALA, minerals, vitamins C, E, B vitamins -except B12- and reduced glutathione (very important antioxidant for mitochondria), polyphenols, pigments and flavonoids.
- Chlorella - (50-60% protein) another cyanobacterium comparable to spirulina containing all 9 EAAs, vitamins - including D and B12, higher in folate and iron, minerals - except copper, DOES contain B12 - an ideal 1.5:1 ω 6:3 ratio including DHA, EPA and ALA.
- Calculate how much YOU need for your body. If you are running low, add a soft-boiled egg to your salad - I make around 8 at a time and keep in the fridge to grab and go - make a smoothie with chorella and spirulina - add some Greek yogurt to anything.
- Move your body! Muscles can only synthesize new muscle postprandial if ALL amino acids are present in enough quantity to not steel from other muscle tissue.
- HP-EVOO - add high polyphenol extra virgin olive oil to your foods to enhance absorption of fat-soluble vitamins, minerals and utilization of nutrients, feed microbiome and mitochondria, inhibit oxidative stress and so much more. The polyphenols in EVOO “maintain genomic stability by protecting DNA (nuclear and mitochondrial) and cellular organelles (especially mitochondria) against oxidative stress and by stimulating endogenous antioxidant defenses. Therefore, they are involved in delaying cellular senescence through the modulation of age-related chronic inflammation…In older, obese subjects, EVOO administration during energy intake restriction stimulates protein synthesis and delays the loss of skeletal muscle mass and strength with an improvement in physical performance and quality of life.”
So, until next time my friends…Drink, Drizzle, Digest HP-EVOO 2-4T raw daily, - use more for cooking and drizzling onto your food - eat the rainbow of organic or wild-sourced veggies (7-9 C) and low-glycemic fruits (to get the rainbow of gut microbes!) Eat wild-caught, pasture-raised, grass-fed, get plenty of sunshine + supplement magnesium, zinc, vitamin D3 + K2, get your trace minerals and electrolytes with good sea salt *Himalayan was formed before plastics, eat foods high in lutein, drink your body weight in oz of water, get a good pre/probiotic (if you have wiped out your gut microbes with antibiotics), consume digestible and indigestible fiber for your gut microbes, fermented foods for the post-biotics, adaptogens (such as mushrooms) and methylation donors (kale, beets, spinach, cruciferous, lion’s mane…), marjoram, rosemary, oregano, parsley and other herbs to detox, enhance overall health and reverse aging and disease, exercise your body and mind, add a few minutes of mindful meditation to your day to combat stress, take a hot epsom salt bath and follow with a cold shower/ice plunge, remove EMF (electromagnetic frequency) devices and blue light, use IR (infrared) from incandescent lighting, non-toxic candle or light a fire to enhance sleep and...turn off the light!! #HP-EVOO
