Amanda Williams, MPH:

[00:00:40] The COVID-19 pandemic changed our society and especially in regards to work, that commonly people are working remotely, so their meetings, their conversations, exchanging info and ideas is often virtual, and this is leading to spending a great deal of time on computer and smartphone screens. So people of all age groups are becoming aware of vision health and are increasingly seeking info on eye health. So many nutrients stand out when it comes to vision and eye health, and possibly chief among them is lutein. We’ll explain what that is later on and the foods that can supply lutein. So your screens, all those screens from your computer, your cell phone, your high-definition TV, your video games and of course, outside the sunlight, it depletes your eyes of lutein, but it also depletes the brain of lutein. So in healthy young people and also middle aged people, this leads to eye fatigue and even brain fatigue. But in our elderly, me included, this actually contributes to vision loss and even some memory loss. So in my opinion, the health benefits of lutein are strongly underestimated, and it is important for ophthalmologists and optometrists to inform their patients about lutein that could be derived from foods, but as you get older, it becomes increasingly important to supplement with lutein. So hi, my name is Jerry Hickey. I’m a licensed pharmacist specializing in nutrition, which I’ve studied for many, many decades. Welcome to my episode, Doctors and Supplements, Episode Two: Eye Doctors Need to Know About This Supplement.

[00:02:50] So let me get into this. It’s hard to say enough about lutein. Several decades ago, researchers at Harvard Medical School found that older people who ate a great deal of green leafy vegetables generally had better vision than their peers. Soon after, it was discovered that the most prominent nutrients in the greens were pigments called lutein and zeaxanthin. Now, lutein is a, an amber-orangish pigment, zeaxanthin is yellowish, in fact, you find it in corn. Corn is called zea maize. They named zeaxanthin after zea maize. So these are in the carotenoid family. We know of many, many, many hundreds of carotenoids. Many are very important to the human body, such as astaxanthin, which is the pink carotenoid you see in cooked shellfish and in flamingos or beta carotene that you find commonly in plants and also lutein and zeaxanthin, they’re very important… Lycopene, the red one in tomatoes and other fruits. They’re very important for human health.† [00:04:02]

ANTIOXIDANT CAROTENOIDS FOR A LONGER, HEALTHIER LIFE – INVITE HEALTH PODCAST, EPISODE 283. Listen Now>>

[00:04:04] Now, an early study was from the Moran Eye Health Center, that’s at the University of Utah. They took a pretty good sized population of elderly people, and it gave them either a placebo, which is an inactive substance, or a supplement of lutein and zeaxanthin every day for a year. And they found that eye health improved, vision was better, in the people taking the, the lutein. So why… So that’s just an example of some of the evidence behind it. But there’s many, many, many hundreds, perhaps thousands of studies on lutein at this point in our health.† [00:04:41]

[00:04:42] So why the issue with lutein and electronic screens? Electronic screens like your cell phone and your computer use LED, light emitting diode, background technology. This gives greater clarity. It enhances the colors. It’s more, more vibrant a picture. And part of that is it emits blue light. Now, blue light has a very short wavelength, so millions of rays of blue light are hitting your, your eyes when you’re on your computer or cell phone. And this creates a glare. These flashes create a glare, and lutein is meant to absorb and protect the eyes from blue light. That’s one of its outstanding benefits because blue light can really damage the eyes. So a young person on computer screens all day long, they’re using up their lutein, their eyes and their brain get fatigued and simply reestablishing lutein takes care of that. In fact, some of the younger people I’ve known in college and also a lot of IT people, I’ve recommended lutein to them who were studying, who are doing intensive studies. So what are some sources of lutein? Well, egg yolks are a good source. Green leafy vegetables like spinach and broccoli and Swiss chard. Pistachio nuts have a little. As far as supplements, the major source has been marigold flowers, and there’s a great deal of research on that. These supplements absolutely work.† [00:06:20]

https://www.invitehealth.com/podcast?epc=invitehealthpodcast

[00:06:22] So what does lutein do in the eye? There’s this protective moat in the eye, a barrier called your macular pigment, and one of its activities is absorbing blue light. See, in the back of the eye where vision takes place, there’s a lot of little vulnerable organs that could be damaged by, by blue light. So the macular pigment, this kind of catcher’s mitt, blocks the blue light from getting into the back of the eye. It’s largely made out of lutein and zeaxanthin and meso-zeaxanthin and there’s a lot of the mineral zinc in there, too. And inside the same macular pigment, there’s a little structure called a fovea, which looks like a broken egg yolk. That’s really important for core vision. When you’re looking at something, you’re really only clearly seeing something about the size of a breadbox in your vision. The rest of your vision is just kind of a little bit out of focus, right? That’s the full view. So if that gets damaged, if your macular tissue gets damaged, you develop basically a dark hole in the middle of your vision. It’s a form of blindness, in fact, it’s the most common form of blindness in elderly people. The most common form of blindness in young people, which happens in areas where there’s wars and famines is xeropthalmia, where they’re they’re lacking Vitamin A, A as is in apple. But in older people, it’s due to a lack of lutein and zeaxanthin, which are not Vitamin A, but they’re relatives of Vitamin A in their structure.† [00:07:52]

[00:07:53] But lutein is also important for brain power. So when you deplete lutein in the young, they develop eye fatigue and brain fatigue, but giving them a source of lutein refreshes the brain and the eyes, but… And this is true for middle aged people too. But in us elderly, when you deplete lutein consistently, it affects our memory as well as our vision. Now, here’s some interesting research on lutein and the brain. Studies, early studies from the United States showed that lutein is the prominent pigment in the brains of babies. 60% of the pigments in the brain of babies is lutein. But then people who are octogenarians and centenarians, the amount of lutein in the brain drops dramatically. In fact, it was this very interesting study done down south, I think it was done in Alabama, where they took a large population of centenarians people, 100 years or over 100 years of age, which is amazing, couldn’t have done that 20 or 30 years ago, right? Get such a good population. I think it was 100 elderly people. And when they checked their, their brain power, the ones with greater brain power had more lutein in their brain.† [00:09:18]

[00:09:20] So a systematic review is one researchers looked through evidence of something. It could be a drug, it could be a food, it could be a disease, whatever it is, something scientifically. They do a a screening of all the studies out there. And that’s easy to do today because we have all these electronic sources such as PubMed. That’s the Library of Congress website, where they collate all research on, on, on nutrients and medicine, etc. And there’s Embase and Ovid. There’s a whole bunch of these electronic websites where researchers can now go and very easily download studies on anything, basically anything to do with health, so in this case, it’s lutein, and then they do a meta analysis so they choose the study that are looking at exactly what they want. But the studies have to be high quality. They have to be well-designed, well-reported, lacking bias. That’s called a meta analysis. That’s important because when a meta analysis is done properly, it tells you of something either works or it doesn’t work. So there’s been many scientific reviews, meta analysis where they bunch these studies together and they find that lutein really does benefit older people’s eyes and also older people’s memory. In fact, throughout your age, throughout your life, your lifespan, whether you were an infant or an adult or elderly adult, lutein is important for your brain and vision.† [00:10:57]

[00:10:59] So this is the journal Nutrients, and this happens to be a meta analysis that was published May 2021. It’s the Department of Cognitive Health Sciences. That’s the University of Toshiko. It’s in their division where they also study memory, aging and cancer. And also researchers in England at the University of East Anglia in Cambridge. And they looked at nine studies in total. They found seven studies using brain scans using MRIs, functional MRIs, magnetic resonance imaging, and two studies where they used electroencephalograms of the brain. So nine studies in all, very high quality studies. They found that 10mg of lutein a day as a supplement, natural lutein… And always take lutein with food. It’s fatty-soluble. It’s absorbed better with food. It improved brain activity, but it also, well, it improved the structure of the brain, which was very exciting. And this is in healthy older adults. So it improved the function of their brain during resting or during cognitive tasks. So when the brain was challenged with a test or doing math, et cetera. But they also found that it directly affected the volume of the gray matter of the brain. So in the gray matter, which is many, many billions of cells as well different estimates, sometimes 80 billion, 100 billion, 50 billion, but it’s a lot of cells. In a gray matter, memory takes place for the most part, and it has to be rich in lutein. And they found that when they gave these people, elderly people lutein, not only did it improve the function of the brain and support memory structure and memory activities, but gray matter volume increased. It actually supported the volume of gray matter. I mean that’s some interesting… I’ve only seen two things do that. One is lutein, and the other thing is type one collagen. Apparently, the brain has a large volume of type one collagen.† [00:13:10]

NOT ALL COLLAGEN TYPES ARE THE SAME – INVITE HEALTH PODCAST, EPISODE 370. Listen Now>>

[00:13:13] So my recommendation? For young people, you can easily absorb lutein from food, and these foods are good for the heart, they’re good for the eyes, the brain. Obviously, they’re good for your, your circulatory system. They have anti-cancer effects. There’s a lot of benefits from these green leafy vegetables. But older people have more difficulty absorbing lutein from their food for some reason. So they really should supplement their diet with a good lutein supplement. There is one called Lutein 2020, and that also has zeaxanthin and other forms of zeaxanthin that are good for vision. Now other nutrients that are good for the eye? I mean, obviously the eye is complex, just like the brain. And interestingly, the supplements that have value for the eyes have value for the brain. So why should that be? For the supplements, for nutrients to get to your eyeball, they have to go through the brain first, and the brain grabs all the nutrients it needs, and whatever’s left over, it gets to the eyes. So if you’re not absorbing enough from your food, not enough is going to be there possibly for the brain, but certainly not for the eyes. So fish oils, omega-3 fatty acids, which are longer chain omega-3 fatty acids and shorter chain ones from like vegetables like flaxseeds. A little bit of omega-6 fatty acids, which are found in vegetable oils. They’re also found in evening primrose oil. You don’t want to overdo the omega-6 fatty acids because that can lead to inflammation. But omega-6 fatty acids are needed by the eyes. In fact, they found that dry eye disease and dry eye syndrome you can really help treat it with omega-3 like fish oils and omega-6 vegetable fat helps with dry eyes caused by things like contact lenses. Zinc is very important for the eyes, and it’s very important for the brain. We’ve done a number of podcast episodes on zinc for the immune system, for vision, etc. Very important element. And zinc is another nutrient that you absorb less with age. So older people really should consider taking a zinc supplement, especially since it’s so important for the immune system. Vitamin C, you could get that, of course, from fruits and vegetables. A Vitamin E, natural Vitamin E is very important for the eyes. They protect your eyes just like lutein and zeaxanthin shield the eyes, so do Vitamin C and Vitamin E and zinc. They work as anti-inflammatory antioxidant nutrients in the eyes. Beta carotene found in vegetables, very important for the eyes. Really should be natural beta carotene, synthetic beta carotene doesn’t work well. Just like Vitamin E should be natural. The synthetic Vitamin E doesn’t work very well. Beta carotene is converted to a form of Vitamin A that creates rhodopsin. So you could see clearly and you could see well at night, etc. B-vitamins are important for energy for the eye. A B2 directly works in the eyes. You know it’s called riboflavin. Magnesium and taurine are important for the eyes. Magnesium’s an amazing supplement. In fact, I did a podcast episode last week looking at magnesium for cardiologists. Taurine, on the other hand, is a sulfydryl amino acid. It’s kind of like in a class of its own. It’s very important for the brain, is very important for the, for the gallbladder and the kidneys. It’s very important for the heart’s circulation. It’s also very important for your vision. You could get taurine from fish.† [00:16:39]

Amanda Williams, MPH:

[00:00:40] You’ve probably heard that vitamins and minerals are pretty important in our body. Today, I want to focus in on a particular micro mineral that’s incredibly important for our cellular health and has been linked to so many different cancers. So when we have low levels of this particular mineral, this can certainly be problematic. So I want to talk about the importance of it, the science behind it, how it’s working in the human body, all of its many different functions and what you can be doing to support your selenium levels. So I’m Amanda Williams, M.D., M.P.H., and let’s get right to it.† [00:01:16]

[00:01:16] Let’s talk about selenium. We certainly understand that selenium is a trace mineral, meaning that the body generally only needs a small amount. It’s found naturally in foods. The problem is is that there are pockets within the United States where the soil content of selenium is actually quite low. Now, does this drive up a true deficiency in many Americans? No, not necessarily and part of this is because of, you know, food traveling across the country from areas that are rich in selenium and making them, their way over to to places that are maybe lacking in that selenium content. But we certainly know that places such as Connecticut and Indiana, Illinois, Massachusetts, New York, Ohio, Oregon, Pennsylvania, Rhode Island are all states, and Delaware, I don’t want to forget Delaware, are all states where the soil itself is lacking adequate selenium. So we know that selenium supplementation is often incredibly advantageous, especially in those areas.† [00:02:21]

[00:02:21] As I mentioned, to have a true deficiency, yeah, that’s not always going to be the case, but the likelihood that you have an insufficiency or just low levels, which can certainly be problematic, is something that we certainly don’t want to, to overlook and seeing all of the different ways to which selenium is playing a role in our immune system and many other functions. And so I want to talk about this. So we know that it’s essential for our health, this little tiny, little micro mineral. It’s a trace mineral, as we call it, and we certainly can recognize it when it was discovered all the way back in the 1800s that it plays a really significant role in human health. So what is it actually doing? What’s its function in the body? Well, we can look at how it works inside of the cell to repair our DNA. So if you have damage done to that main motherboard within your cell, that’s a big problem. And so this is where that cancer connection comes in because we understand that cellular DNA damage is what drives cancer. So if we’re lacking selenium, we can now see that our cell is struggling to repair itself and fix that DNA. It’s kind of like if your computer crashes and you’re at a loss, you don’t know how to fix it. That’s a problem. So this is where the selenium comes into play. We know that it’s integrally involved in thyroid function. We can certainly look at its impact when it comes to cardiovascular health. There have been studies looking at low levels of selenium and the correlation with heart disease.† [00:04:04]

THE BASICS OF INVITE HEALTH’S GENETIC TESTING – INVITE HEALTH PODCAST, EPISODE 340. Listen Now>>

[00:04:04] Now, when it comes to our immune system, both the innate and the adaptive, that’s your immediate and delayed immune system response, we know that selenium is critical to this. So if we have inadequate selenium coming from our diet and we are not taking supplementation, then we’re kind of setting ourselves up for immune problems. We want to make sure our immune system is nice and strong so we can fend off any of the little bugs and creepy crawlies that come our way. Now we can also see how it’s important when it comes to our exposure to heavy metals. So when we think about things like lead and mercury and arsenic, we know that selenium is important when we think about the body’s ability to remove those heavy metals. We don’t want those heavy metals to find a home in our body and hang out. We know it works integrally with Vitamin E, which we know is one of our most important antioxidants in the body, but we can see how selenium partners up with Vitamin E to really heighten this level of antioxidant, free radical fighting capabilities that Vitamin E already has.† [00:05:21]

https://www.invitehealth.com/podcast?epc=invitehealthpodcast

[00:05:22] So when you look at people who potentially have inadequate selenium in the body, we can look at problems such as just feeling weak and fatigued. Because remember, your cellular DNA can’t repair itself. We can look at folks who maybe have recurrent infections because it’s impacting your immune system. We can certainly look at it in reproductive health. We’ve seen that males who have low selenium levels will often have a low sperm count. We can see that it can impact our hair and actually create a situation where we’re losing pigmentation in our hair. It’s actually even been linked with vision health and cataracts, the development of cataracts. So this is an area that we definitely don’t want to overlook.† [00:06:09]

[00:06:10] Now you don’t need too much selenium. You know, too much of one thing isn’t always a good thing. We certainly see this to be the case when it comes to selenium. So we know it’s helping our DNA. We know it’s helping us eliminate toxins. We know it’s bolstering up our immune defenses. It’s helping to support our metabolism and our thyroid function. And certainly, we know that when it comes to heart health, when it comes to making sure our cells aren’t becoming problematic where we then develop cancer, this is why we need to not ignore the importance of selenium. And one of the things that science and the research has shown is the fact that selenium, this little tiny trace mineral, has all of these functions to, you know, keep the body safe from oxidative stress, to allow our thyroid to function every single day, to keep our immune system strong, to promote the health of our brain, our eyes, healthy cell division, promote the health of our heart. These are integral, and when we take selenium along with Vitamin E, this really allows our cellular health to be much stronger.† [00:07:32]

[00:07:33] So where do we get exposure to selenium when we look at different foods? Certainly, it’s a wide spectrum so we can look at certain seeds and nuts. We can look at certain fish like cod, for example, shrimp. But some people don’t eat fish. Some people don’t eat seafood. We can look at garlic. We can look at lentils as a source. We can certainly look at things like carrots and cabbage, almonds, pecans. I had mentioned the nuts. So we know that there are many ways to which we can incorporate selenium into our diet. The problem is, is that many people may not be getting a high enough exposure to those good, healthy foods. If you’re following a Standard American Diet, the likelihood that you may still be lacking in your selenium exposure each day is pretty high. And this can be problematic, especially if you’re in one of those states where we already know that the locally grown foods are going to be lacking selenium. So this is why we want to make sure, because for people who have insufficient levels, you know, maybe you have headaches, you know, chronic headaches, and you don’t know why that is. And maybe it’s because of just this insufficient intake of selenium. There’s many ways to which selenium insufficiencies can present itself. And then scientifically speaking, when you start to look at how important it is when it comes to that cellular division and the compounds contained within this micro mineral are so incredibly important in terms of that cellular division. And this is why they’ve been able to to look at epidemiological studies indicating that in areas where the population has low selenium levels, they are at a much greater risk for developing many different types of cancers. So in particular, they, they’ve zeroed in on things such as lung cancer, liver cancer, stomach cancer, bladder cancers. Now that’s not saying that there’s not the correlation between prostate cancer and breast cancer. Certainly there is, but we know that when it comes to promoting our longevity and helping to support our cellular health and that very important motherboard that DNA, we have to have selenium.† [00:10:02]

[00:10:03] So getting that exposure can come in different ways. My advice is always use our Core Multivitamin. That’s an excellent way to get a good exposure to selenium. You’re getting the comprehensive Vitamin E. Remember those to partner up to help to support your health. But you can also use our Women’s Multivitamin, our Men’s Multi, our Performance Multivitamin. They’re all going to give you a good amount of selenium to make sure that your body can go through all of these different things that it needs selenium for each and every single day. For the immune system, for your heart, for your brain, for your eyeballs. And this is certainly important. It’s one of those minerals that we don’t talk about enough, but its impact in our body can be life changing. So do make sure that at a minimum, you are taking a comprehensive multivitamin, multimineral formulation, such as the InViteⓇ Core Multi.† [00:10:58]
