DO YOU GET ENOUGH PROTEIN IN YOUR DIET?

Episode 137

Do you get enough protein? There are protein powders, protein shakes, and protein bars. But how much protein do you actually need? Then there are high protein diets. Are those good for you?  Are you getting enough protein in your diet? Maybe too much stay tuned to find out if you’re getting the right amount.

It seems like we’re just bombarded with this message to make sure we get enough protein and yes, you definitely need enough protein. But chances are you get plenty.  The average American diet is 16% protein. Well, that translates to 80 grams a day. If you follow the recommended 2000 kilo calorie diet. On top of that, most Americans eat protein that is packaged with fat. And that definitely has some negative health consequences. 

Today, we’ll discuss the amount of protein that’s right for you and the best sources

We do need protein if you don’t get enough protein, you can have brittle hair and nails. You can feel hungry all the time or your muscles can be weak. Your immune system can be compromised, so you get sick a lot. You can even have trouble thinking or changes in your mood, or stress fractures in your bones.  

So let’s go to mini medical school for a review course. There are three essential macro nutrients that our bodies absolutely need to function. Fat carbohydrates and protein. And gosh, when I say those three together, I think the protein hype comes in from the bad rap that fat and carbs get. Remember one gram of protein is four kilocalories.  Same for carbs and fat is nine. But you do need all three macros and like everything in lifestyle medicine, it requires balance.  And on top of the macros, there are lots of micronutrients, but here’s the deal protein is never a solo act. I mean, you can’t really just eat a protein. 

Proteins are macromolecules. Well, that just means they’re big old suckers made up of long chains of amino acids, and you may have heard them called building blocks. There are 20 different amino acids and we need every single one of them to live. but your body can make 11 of them. So nine of them are essential in your diet. A complete protein has all nine of them, Most protein in our diets are not complete. But not to worry your pretty little brain about that. We will talk about how to get a complete protein.

Amino acids are kind of like Lego’s, they fit together to make proteins, but unlike Legos, they don’t make you cuss when you step on them. And like Lego’s for mothers of little boys. Amino acids are everywhere and you can snap proteins together to make muscles, hair, enzymes, and antibodies. They break stuff down in chemical reactions in the body and they’re important for DNA replication. 

We need protein for every organ in our body to function like it’s designed the heart, the brain, the skin, the immune system. And it’s especially important for the musculoskeletal system. Adequate protein intake helps build repair and maintain muscle. And that’s not just for bodybuilders who want big ol honkin muscles because as we age. Staying strong becomes even more important. Protein may play a role in appetite control. And that’s why a lot of these diets focus on high protein for weight loss. And we’re going to talk about that in a few minutes. But not getting enough protein can lead to hair loss, skin breakouts and breakdowns, weight loss, loss of muscle mass and weakness.  This is most likely to happen in people with eating disorders or the elderly who have an inadequate caloric intake. Now let’s get to the bottom line. How much protein do you need? 

 You’re going to need to know how much you weigh in order to do the math and the simple answer is that you can multiply your body weight in pounds by 0.36 and determine the minimum number of grams of protein you need. Of course, there are situations where you need more  like how old you are, whether you’re a man or a woman. Your activity level and pregnancy.  Okay, active adults need 0.6 to 0.9.  Older adults need a little more too. They’ve got to maintain that muscle mass. So 0.8 times, your body weight in pounds. And the reason older adults are at such risk again, is because of decreased appetite, decreased calorie consumption, and the importance of staying strong. So you don’t fall, or you can open a jar and all the other things you need to get done in a day. Okay. What about athletes? Well, they do need more. 1.2 to two. So let’s look at that just a little bit different way. And for those of you who are on my email list, I’ll send this out in print because it’s so much easier to look at that way. 

Sedentary adults need 10 to 15% of their calories from protein. Active adults need 15 to 25%. And athletes should consume protein as 25 to 35% of their diet.  And with all the hawking about protein, you’d think we’re all deficient. But on average Americans get  the amount of protein they need. In general, if you’re eating enough calories. You’re probably eating enough protein. Can you get too much? 

Well, yeah, too much isn’t good either. In fact, men aged 19 to 59 typically get more than they need from chicken eggs and of course burgers and the steak.  But what about that meat eating man who pumps iron and sweats on the treadmill, you may be surprised to learn that even athletes do not need a supplement to get enough protein, they need more calories to fuel their workout. But they can get that protein in food. Isn’t that such a beautiful design.  Now I mentioned in kind of a fancy way that protein contains nitrogen. So your body needs fluids to process nitrogen and too much protein can make you dehydrated. It strains your kidneys and people who have kidney disease need to be really careful about finding that balance between not enough and too much.  And protein, especially from animal sources can upset your tummy and cause either constipation or diarrhea. 

So maybe you were worried about getting enough protein and maybe you’re worried about getting too much.  But let’s talk about protein powders that people add to shakes. The most common ones are whey, pea, and soy. And they’re  processed, they’re  sweetened, And they all contain a lot of other ingredients. Whey protein is made from milk protein. It has flavors in it and sweeteners and preservatives and emulsifiers like lecithin and thickeners like xanthan or guar gum. And some of them add vitamins and minerals. 

What about soy protein? Well, it’s made from soy protein concentrate. It has natural and artificial flavors, sweeteners, emulsifiers, like soy lecithin, preservatives, and thickeners, and sometimes vitamins and minerals.  What about pea protein? It’s made from yellow split peas. It also has flavors, sweeteners, emulsifiers, thickeners, preservatives, and sometimes vitamins and minerals.

You know, with all those sweeteners, flavors, emulsifiers, and thickeners, what if you just got your protein from food? Isn’t that a great concept? Now I totally get just putting powder into a shake because it’s faster. It’s easier. And it’s just so convenient. Soon I’ll have a recipe ready for a protein smoothie that tastes delicious and doesn’t have all of that extra junk in it. It’s going to be available through the healthy looks great on you lab. Right now it’s by invitation only. But if you’re interested, make sure you’re on my email list. I’ll open it up soon to everyone. 

 And here’s the deal. Variety is the secret to getting complete proteins. So we always say, eat the rainbow. That means eat food with different colors, oranges, purples, blues, greens, reds, yellows and everything in between.

I mean, who doesn’t love a colorful package?

And that brings me to a term I want to introduce you to. Protein package. Hello protein package, it’s nice to meet you.  Because remember, you can’t eat a protein by itself. So basically, a protein package refers to who the protein is hanging out with. 

Let’s make it specific and go back to that pile of chicken that was on my Korean rice bowl.  One cup of chicken breast has five grams of total fat. Which is another one of the essential macros. 1.4 grams of it is saturated and 1.7 grams is monounsaturated, and 1.1 grams is polyunsaturated.  It has a total of 43 grams of protein. Based on my weight and activity level, that’s about half of what I need in an entire day.

Chicken breast is a lean protein source, so a lot of people eat it on the Mediterranean diet. Now, edamame is made from young, green soybeans. And they are so good for you. And they’re very versatile as well. They have 188 calories. compared to 231 for a cup of chicken breast. They have 18. 4 grams of protein, which is not nearly as much as chicken.

 But I can guarantee you that I’m going to eat more than one time a day,  but here’s the real kicker.  Edamame has 8 grams of fiber. And fiber is super important if you’re trying to lose weight, or you want to maintain gut health. It’s good for your immune system, and your digestive system, and your body in general.

In  fact, edamame is a complete plant protein. Remember, I told you a complete protein has all nine amino acids. And it’s rare to get a complete protein in plants, but edamame is the package that does it. You can add it to salads, you can put it in stir fries, you can put it in soup, you can just eat it as a snack. It also has lots of vitamins and minerals in it like folate, vitamin K, and iron. And for your heart, it contains healthy fats that include omega 3s and omega 6 fatty acids. And those can actually help reduce bad cholesterol levels. And remember, cholesterol is not found in plants and fiber is not found in animal products. 

 If you get most of your protein from animal products, you’re likely getting a lot of fat with it. And we all know that too much saturated fat can increase the bad cholesterol in your bloodstream. That’s the LDL cholesterol. And that can lead to heart disease. Saturated fat also causes inflammation throughout the entire body. And that ups your risk for just about everything. On the other hand, plant based proteins, which come from things like soy or edamame, nuts and seeds and beans and grains, those are lower in saturated fat, but they’re high in the all important fiber, 

Here are some good plant-based sources that are complete as well. Besides that edamame or soy is buckwheat, hemp seed, and quinoa. Look for ways to add these to other things in your diet. I’m going to have more specific information on that in the healthy looks great on you lab coming soon.  

The bottom line is, more protein isn’t better, better protein is better. So we should focus on quality and not quantity. And, we should get our protein from food. Because all of those protein powders that people add, those are considered supplements, and it is big business.  And that’s probably why protein is being marketed to us as if we all have a shortage.  And even if we do, we should get our protein from food. Whole food is best. Now, let’s go ahead and compare plant protein to animal protein. 

Let’s start with animal based proteins. This includes chicken, turkey, beef, pork, fish, eggs, dairy products like milk, cheese, and yogurt. All of those contain protein.  The most complete proteins come from animal sources. And they’re actually more likely to contain complete proteins because animal proteins have all nine of those essential acids. So that’s a good thing, right?

It is.  And they often have other nutrients like vitamin B12, which isn’t found in plants, as well as iron, which you need to maintain a good red blood cell count and keep from being anemic. As well as omega 3 fatty acids, especially in fatty fish, like salmon. 

Now, the more processed a meat is, the less healthy it is for you.    Red meat is worse than poultry. And all animal protein is packaged with its good old buddy fat, which we already talked about.  Now, comparing that to plant based proteins,

that’s better for your heart. They’re rich in fiber, which we talked about, but what we didn’t mention before was antioxidants. Plant protein sources are excellent sources of antioxidants, and those are the cleanup crew in the body that get rid of cells that can cause damage and disease. They can even lower your risk for heart disease, stroke, as well as cancer.

Now, the problem is, there aren’t too many complete proteins in the plant world. But, I gave you the secret earlier, do you remember what it is? You don’t even have to go to mini medical school, you learned about this one in elementary school.  The rainbow. Eat the rainbow. If you eat a variety of plants, You’ll get all the amino acids that your body needs. 

So, don’t just eat one kind of plant, don’t just eat spinach all day long. I mean, Popeye did have big muscles, but,  you should also eat grains, and beans, and legumes, and nuts, and seeds. 

If you’re eating a completely plant based diet, you  need a B12 supplement, and you do need to be more mindful of your protein intake. Because it’s definitely more of a challenge, especially if you’re active, and I sure hope you’re active.

Before we wrap up, I want to mention one more thing, and that’s timing.  It’s really better for your body to get protein spread throughout the day, ,  instead of eating a big steak for your evening meal, and getting it all at once. Our bodies don’t really store protein. Like they do fat. So you only need as much as you need for one day. 

Generally speaking, you should get about 15 to 30 grams of protein  per meal and spread it out throughout the day. There are some studies that show if you eat more protein in the morning, it decreases hunger and cravings throughout the day and that can help with weight management.

While I’m on the subject, I want to mention high protein diets for weight loss. Studies show that they are effective in the short term. So, think of them as a kickstarter, not a way to live, because in the long run, they’re not good for your cholesterol, and they’re not good for your heart.

If you missed the episode comparing the different diets, I’ll put a link in the show notes to which diet is healthiest, or you can go to my website and search for it.  

The most important thing is, don’t buy into the marketing schemes.   Just make sure you’re getting enough. And remember, if you’re using a protein powder, it’s got a lot of other junk in it, and it’s really considered to be a protein supplement. You probably don’t need it. You need to eat more protein in your food. So let’s look at the top plant foods that contain protein.  One of the highest sources of protein in the plant world is one of my favorites.  Did you say edamame? No, that was a trick question. It’s lentils. Remember, I love lentils. And one cup of red lentils has 18 grams of protein.  In addition to all that fiber and phytonutrients and vitamins and minerals.  And remember, no cholesterol.

Now, edamame is second on the list at 17 grams of protein, and another favorite of mine, black beans, comes in at 15 grams of protein. Moving on down to some nuts, almonds contain about 6 grams, peas are 5 grams, and even a baked potato has 5 grams of protein.  You know what I do?

I put black beans on top of a sweet potato. It’s delicious. I’ll share my recipe with you sometime. Spinach has five grams of protein as well so don’t forget those leafy greens.  Now how does that compare to animal protein? Well, we already talked about chicken and we talked about a cup. But even just three ounces of steak has 25 grams and it has all that cholesterol, saturated fat, and no fiber in it.

Salmon has 20 grams of protein for just a 3 ounce serving, and it’s better than red meat. And an egg has 6 grams, so you can have a cup of spinach, a cup of peas, and get nearly the same amount.  Now, since protein is being marketed to us as if we all have a shortage, let’s talk a little bit more about a comparison of plant protein to animal protein.

There was a study published in 2020 in the Journal of the American Medical Association Internal Medicine Edition that suggests that where you get your protein really does matter. In fact, they looked at almost half a million people over the age of 50 who got their protein from either plants, red meat, or eggs. And they watched them for 16 years and guess what? People who ate mostly plant protein instead of red meat protein had a 13 to  24 percent lower risk of dying from all causes.  That’s impressive. In this particular study, the effect was even more pronounced on men. For every 10 grams of plant protein they ate per 1, 000 calories in their diet, they had a 12 percent reduction in their risk of death. And if they ate more, likely that number would go up even higher.  

 Remember, better protein is better. Plant protein is healthy.

 And healthy looks great on you.
