OUR IMMUNE SYSTEM IS OUR FIRST RESPONDER DEFENDING AND PROTECTING US from potentially disruptive, harmful invaders. Our overall immunity determines how we will weather any onslaught of bacteria, mold, fungus, virus, parasites, heavy metals, and chemicals. Additionally, our immunity is subject to highly inflammatory lifestyle factors, such as a diet high in processed and refined carbohydrates, a high intake of sugar and grains, stress, lack of sleep, reduced exercise, unexpected trauma, and physical challenge and change as we advance through life. While we are meant to be strong and resilient throughout life, we are more at risk for autoimmune conditions and infections when our toxic burden “runneth over” and the immune system is unable to function in the way it was designed to optimally perform.

The reason the Rules work together, much as the systems in your body, is that every day your DNA is being damaged in some way. A healthy person replaces or repairs their damaged DNA at about the same rate that it was damaged. This is why it is so critical to address our overall health as we age, so that we are advancing our healing, repair, and restoration, not relaxing into “normal” decline over the years. When your hair starts to gray, skin starts to sag, or memory starts to fade, these are signs your body is not able to do all the DNA repair it needs, and oxidative damage is accumulating. Think of these as calls to action rather than an inevitable trajectory of your life and health. Because your immune system is a full-body defense system, the information throughout Radical Longevity can have either a direct or indirect impact on your immunity. For that reason, I suggest that you begin your approach in the following way:

Invest. Your immunity fortifies you and is an important assurance in vibrant living. You’ll see suggestions and recommendations throughout this book, some dealing directly with immunity and others that affect the immune system as a result of your overall health. It is important to begin thinking about your life holistically—body, mind, spirit, and environment. All are intricately and elegantly connected, and each affects the others. Your time, money, and energy are your resources to use and rely on as you make decisions about how you will invest in your present and future well-being.

Be vigilant and take action. Don’t wait to start taking corrective steps, believing “It will get better.” That is outdated thinking—we now know that repair is our best defense and early action can greatly reduce recovery time from any challenge or injury.

Every effort counts. Be they small or large, inexpensive or more costly, your efforts count and either add to, or subtract from, vibrant health. Don’t ever think that one simple action a day won’t make a difference. Everything counts.

Upgrade and update. New science is emerging all the time that tells us more about how to enhance our health. Don’t get stuck on any one remedy; be open to trying something new or at another level.

Be your own laboratory. Notice the results as you make changes and increase effort. Keep a diary or create a checklist of desired and expected outcomes that you want to see and at what level and frequency. If you don’t actively take notice of the effects of your efforts, you’re missing a great chance to fine-tune what you need. Your health-care practitioner is reliant on your compliance with follow-through and your ability to articulate what is going on as a result. Everybody is different, so you are always going to know more about your own body and experience than anyone else.

Note that before you begin taking any supplements, you should check with your health-care provider for any issues or contraindications.


Let’s start with the basics. As most of us are already aware, vitamin D is essential to maintain strong bones and reduce the risk of fractures. It stimulates the absorption of calcium and magnesium and promotes mineralization and strengthening of the collagen matrix in bone, increasing bone density and overall health of bone tissue. This process starts in the intestine, then the signal travels to the bones and bone marrow, and once the bone marrow is involved, so is the immune system. Interestingly, a 2012 Spanish study compared vitamin D levels in blood levels drawn from three age groups. The seniors studied (ages sixty to eighty-six) showed lower vitamin D levels than the other age groups. This versatile vitamin is not just for bone health. It plays an important role in respiratory health. Through its influence in lung development and respiratory muscle strength as well as reduction of inflammation, it triggers a powerful immune response to foreign invaders. In fact, researchers have found that a deficiency in vitamin D is a risk factor for developing respiratory tract infections. It turns out that vitamin D is such a powerful immune factor for the respiratory tract that the lungs actually produce their own active form of vitamin D.

In addition to fortifying the immune system in general, vitamin D contributes to creating a stronger barrier to viruses by increasing the antimicrobial compounds in mucous membranes—our first line of defense. These membranes are found in your nose, mouth, eyes, lungs, and windpipe. Research supports that vitamin D improves viral immunity by strengthening mucous membranes.

The best form of vitamin D is sunshine. Opt for at least fifteen to twenty minutes at midday in direct sunlight. You want as much of your skin exposed to natural sunlight as possible, with particular attention to legs and arms (be mindful not to burn). And no, sitting by a window is not enough. You need to physically be in the sunlight. This becomes increasingly important in the winter months when we stay indoors and typically have less exposure to sunlight. Natural vitamin D becomes even more critical as the cold and flu season takes hold.

Vitamin D is fat-soluble, so it will typically be found in fatty foods. Sources include beef liver, cheese, egg yolks, fatty fish and fish oil, and even mushrooms, which seem to be the only nonfat food source rich in this vitamin. Like magnesium, vitamin D supports calcium absorption, helping to create strong bones.

As it stands, the RDI (Recommended Daily Intake) for vitamin D is 600 IU (international units) per day. However, in 2014, research from the University of Alberta showed that the official RDI of vitamin D from the National Academy of Medicine is significantly lower than needed to maintain a healthy body. According to the researchers’ statistical analysis, the RDI should actually sit at 8,895 IU per day to ensure that the vast majority of the population has adequate vitamin D in their system. The researchers do note that this dose is higher than any previously studied dose, and caution should be taken when interpreting this number. I recommend a daily vitamin D intake of 2,000 to 5,000 IU of the D3 fat-soluble version of the vitamin, which is more bioactive than D2. Ask your health-care practitioner to ascertain your vitamin D level in a blood test and strive for levels of 50 to 80 ng/ml. Ideally, vitamin D should be taken along with vitamin K2 to be sure that the increased level of calcium that is being absorbed is directed to your bones and not your arteries.


Of course, most of us know the wonders of vitamin C, yet still, many of us don’t think to take it until we begin to feel a little under the weather. Vitamin C is essential to our immunity. It can help prevent respiratory infections as well as help treat and heal infections. Note that our body does not store vitamin C, so you need daily intake. Period. Exclamation point! I recommend a time-release vitamin C, with a recommended daily dosage of 2 to 5 g daily.


If vitamin D is the body’s #1 immunity vitamin, then zinc is the body’s number one immunity mineral (and there’s another connection between the two: vitamin D has been linked to improved zinc absorption). Necessary for over three hundred enzyme-dependent processes, zinc’s importance to your immune system starts with its ability to control many of the reactions to harmful invaders. In fact, a zinc-dependent enzyme is crucial for daily DNA repair; zinc is also critical to the white blood cell’s ability to attack invading bacteria and viruses and eliminate them. Without adequate levels of zinc, the immune system can be erratic, resulting in massive inflammation. Any zinc deficiency can impair immune system function; our immunity often declines as we age in direct relation to declining levels of zinc. Zinc deficiency has been linked to pneumonia and other respiratory infections in seniors.

Good dietary sources of zinc include beets, seafood, eggs, and pumpkin seeds. Although I typically recommend anywhere from 15 to 45 mg of zinc daily, many people over the age of fifty are highly deficient and need to take more. Just keep in mind that the greater your zinc intake, the more likely it is to lower other mineral levels, including copper, manganese, molybdenum, chromium, and the insulin mimic vanadium. Zinc needs to be balanced with copper in an 8:1 ratio of zinc to copper. It is important to test your zinc levels with the most accurate testing, which is RBC Zinc, rather than a plasma or serum blood test. Ideally, your zinc level should be in the upper half of normal. Ask your doctor to order this.


Quercetin is an antioxidant-rich anti-inflammatory that inhibits histamine release, making quercetin-rich foods natural antihistamines. Also valued for its antiviral effect, it has been known to diminish the ability of a virus to infect cells and impede replication of infected cells. This powerful ability to block viral activity, along with its antihistamine effects, has made it an ideal contributor to respiratory health.

Foods rich in quercetin include capers, quinoa, asparagus, cranberries, apples, kale, okra, spinach, elderberries, and red grapes.

Quercetin supplementation is recommended at 500 mg, two or three times a day.


The body’s number one antioxidant hormone, melatonin bolsters your immune system in an amazing way. It increases the antioxidant activity of two powerful chemicals, superoxide dismutase (SOD) and glutathione perioxidase. SOD is an anti-inflammatory that helps repair cells, specifically the damage they incur from the most common free radical in the body—superoxide. Much like SOD, glutathione is a powerful antioxidant and detoxifier. Like a resident handyman, it can repair free radical damage on the spot as well as clean up any toxins and the injury they cause. Melatonin keeps both of these in the fight. Recommended dosage is 1 to 3 mg, preferably in a time-release form.


Getting enough sleep is essential for healthy bone marrow, which is where stem cells are made. These stem cells are essential for repairing everything from your immune system to your brain to your bones, and so much more. Stanford researchers have found that a sleep deficit of just four hours is enough to cut the activity of these stem cells in half. For stem cells to travel to where they’re needed in your body, you first need to get a full night’s sleep. Your investment in getting more high-quality sleep is one of the best you can make.


A nice hot soak can help build immunity by raising your body’s pH to an optimal level between 7.30 and 7.45, which makes it a less hospitable “terrain” for bacteria and viruses. Apple cider vinegar is especially good for relieving aches and pains as well as helping to eliminate uric acid deposits and carbon-based pollution through the skin. I recommend the following soak twice per week during the cold and flu season and once per week at other times of the year.

Run a tub of the hottest water you can manage. Test the water to prevent any scalding. Pour in 2 cups of organic apple cider vinegar.

While immersed, sip a glass of warm water mixed with 1 teaspoon of organic apple cider vinegar.

Get out of the bath when the water is cool. Don’t shower for at least four hours afterward.


A 2019 Harvard University study analyzed hundreds of virus risk factors, including such contributors as age, hand washing, contact with larger numbers of people, adequate sleep, and flu shots. Its findings concluded that the biggest risk factor in determining whether someone developed a respiratory infection was related to the dryness of the air they were breathing. Those studied who were breathing drier air were found to be far more likely to develop an infection. Dry air enables a virus to travel farther and survive longer. Researchers also explained that dry air harms our natural immune barriers—our mucous membranes, whereby they become thinner and less protective.

The answer: a humidifier with an optimal range of humidity from 40 to 60 percent. I suggest prioritizing adding a humidifier in the room where you sleep, since many immune functions and repair are taking place during sleep, as well as having a somewhat controlled environment for a prolonged period of time. However, if possible, you might want to add personal humidifiers to your office, kitchen, and other areas where you spend significant amounts of time.


Much of 2020 was dominated by the mandate to wash our hands. We all know to do it and that it saves lives as well as greatly protects against illness through reducing exposure to bacteria and viruses as well as mold and parasites. What you may not know is that it is the preferred protector because hand washing with soap gives two levels of protection, whereas hand sanitizer provides only one. Since most viruses have a fatty outer layer, soap binds with the fat layer at a molecular level and both kills and eliminates viruses—hand sanitizer simply kills the virus but can leave remnants of it on your hands. Therefore, some virus remnants may not be completely neutralized, leaving you with less protection.

If you wash your hands whenever soap and water are available, using the twenty-second approach and covering all areas of both hands (including tops of your hands, thumbs, and in between your fingers), it is the much better choice. For times when soap and water are not available and hand sanitizer is your best option, be sure it contains at least 60 percent alcohol. Any lower concentration may not kill viruses. I personally use a waterless soap called EssentiaClenz, made with natural plant oils, including thyme, which according to the EPA has been found to contain virus-killing thymol.

Proactively supporting your immune system with key nutrients and lifestyle habits clears a path for your body to be able to age more gracefully. Now, let’s turn to minimizing toxins to further reduce the toxic load that weighs so heavily on modern-day immunity.



OUR EFFORTS TO HAVE VITALITY AS WELL AS A LONG LIFE, IN LARGE PART, RELY ON our ability to rid ourselves of toxins. We are the first generation to have been exposed to a constant sea of chemicals. As unbelievable as it may sound, we are now more likely to get sick from the indoor air in our home or office than from the air outside. According to the EPA, indoor air pollution is one of the leading health risks. In fact, some chemicals may be nearly one hundred times more concentrated indoors than outdoors.

Estimates suggest that each of us stockpiles about seven hundred different types of pollutants in our body. Researchers are now finding that babies are born with over two hundred chemicals in their bloodstream; there’s rocket fuel in breast milk, lead in drinking water, and the list goes on. This early and constant bombardment of toxins takes its toll on our ability to detox and ultimately can cost us our health. Adding insult to injury, many of the very medicines that are supposed to benefit us often come with an alarming number of unwanted additives with detrimental side effects, making them villains in our aging process. While we must make an ongoing effort to rid our body of toxins as we age, we also have to address our toxic overload that has accumulated during our years of living. Detox, repair, and rejuvenate are our primary tasks at this stage of life.

You can live to one hundred—and beyond—in nearly perfect health, as many people around the world are doing. It’s not as hard as you may think. However, to do that, you need to understand what’s going on inside your body and why you’re accumulating toxins faster than you can eliminate them. For the first time in a century, American life spans are getting shorter because of the rise in such preventable diseases as heart disease, cancer, diabetes, and Alzheimer’s. To recalibrate our biological clock and restore optimal health, we must look at the effects of toxic overload in the body as a major contributor to the underlying causes of premature and accelerated aging.


It’s difficult to vanquish the foe you don’t know, so identifying the toxins you’ve been exposed to is the first step to freeing yourself from this unwelcome burden. Once you know who your toxic invaders are, you can take targeted steps to eliminate them from your body and reenergize and restore health to your cells.


Living in today’s world has made our body a lifetime stockpile of way too many toxins. Aluminum, lead, mercury, and copper are so pervasive in twenty-first-century life that it is difficult to figure out which metal is to blame for one’s ill health; each can be devastatingly damaging. Emerging evidence now suggests that many of these and other metals suppress the immune system by producing free radicals that, in turn, help accelerate the aging process as well as degenerative disease.

The metals discussed in this chapter are all in everyday use. Although some are actually therapeutic and beneficial in small amounts (copper, iron, and manganese, for example), they can be toxic in greater quantities. Others, such as mercury, aluminum, and lead, can be toxic to certain individuals no matter how small the amount.

I consider the removal and avoidance of toxic metals to be as essential to my Radical Longevity Program as breathing is to life. Even though efforts toward prevention are well advised and to be applauded, without a systematic and deliberate effort to rid your body of accumulated toxins, your longevity and quality of life will be compromised. After introducing you to the toxic metal sources all around us, I will explain how to eliminate their toxic effects. Let’s first understand why and how they accumulate in the first place.


Part of the wondrous mystery of the body is the ongoing need to compensate for something it determines as lacking. It turns out that when you are deficient in one element, your body will use another element in that group to fill its place. The only problem is the new element is quite often toxic and can’t perform the functions for which the deficient one is meant.

Take, for example, the case of iodine. It is an essential building block of your thyroid hormones, T3 (tri-iodo-thyronine; hyphens added so you can see how important the iodine is) and T4 (thyroxine). Your thyroid takes the iodine from your food and converts it into these hormones. But when iodine is deficient, your body substitutes another element.

Iodine is in the group known as halogens, which also contains fluoride, bromide, and chloride. Chloride is already in such abundant use in the body, it can’t be pulled away to perform thyroid functions. This leaves fluoride—found primarily in drinking water, tea, and toothpaste—and bromide—found mainly in processed white flour and flame retardants on furniture and clothing (more on these later in the chapter).

When the body makes thyroid hormones with bromide or fluoride, they aren’t as biologically active as hormones made properly with iodine—but they still show up on a blood test in the same way. This means you’ll feel all the symptoms of hypothyroidism, an underactive thyroid, but you will appear to have normal thyroid hormone levels on blood tests.

This is similar to how your body uses mercury or cadmium when zinc is deficient. And once these impostors bind to the target receptor sites, they stick like glue and are very challenging to unseat. First, you have to supplement to restore your zinc or iodine stores; then you have to keep supplementing to flood these receptor sites, so you can outcompete the attached toxic metals. Keep in mind that part of the attack plan underlying each of these toxic accumulations of heavy metals is to address the deficiency first. Otherwise, the undesirable metal will keep being substituted, making your efforts that much harder and prolonged.


Aluminum is able to cross the blood-brain barrier, and its toxicity is believed to be associated with neurodegenerative diseases, including Parkinson’s, dementia, and Alzheimer’s. It is also commonly found in vaccines.

Symptoms of aluminum toxicity include mental confusion and memory loss, muscle weakness, heartburn, colic, flatulence, ulcers, spasms of the esophagus, appendicitis, dry skin and mucous membranes, constipation, and immune problems, among others. Due to its astringent quality, aluminum can irritate the mucous membranes in your gastrointestinal tract and destroy the protein-digestive enzyme pepsin in your stomach. Aluminum also hampers your body’s utilization of calcium, magnesium, phosphorus, and vitamin A, increasing your risk for osteoporosis.

Aluminum is present in a wide variety of kitchenware, from aluminum foil to pots and pans. If it’s in your kitchen and made of metal, it potentially contains aluminum. The problem is, when your food encounters aluminum, small particles can make their way into and accumulate over time in your body.


We are most likely to be exposed to cadmium from cigarette smoking or secondhand smoke, as well as many e-cigarettes and vaping products. Surprisingly, it can be found in chocolate of all varieties and also in some seaweeds, including nori (which is used in sushi and as a dried snack). Other common sources include metal containers, cookware with a cadmium-containing glaze, electroplated ice cube trays, and antiseptics.

Cadmium has been linked to lung and prostate cancer, chromosome damage, and reduced birth weight. Loss of smell, runny nose, shortness of breath, coughing, weight loss, irritability, and fatigue result from long-term exposure to cadmium fumes, accompanied by yellow rings on the teeth, bone pain, and kidney damage.


Fluoride, the substance said to strengthen tooth enamel, is another savior-turned-disabler that is added to our water as a dental aid. It is also becoming prevalent in our food supply due, for example, to such pesticides as cryolite, commonly used as a filler in commercially prepared animal feed. Fluoride is a potent factor in aging. It is a primary culprit in the calcification of the pineal gland, and along with aluminum is known to weaken the immune system and cause heart disease, birth defects, and genetic damage. More than 150 studies now show fluoride’s neurotoxicity and links to bone and brain diseases, diabetes, cancer, and digestive disorders.


As you’ve undoubtedly heard in the news, lead in drinking water from corroded lead pipes is a huge concern today. Besides being a common contaminant in chocolate and in many imported products (including glazed pottery), vintage dishware, and glassware, recent testing identified lead as a contaminant in a host of dietary supplements, particularly those with inferior manufacturing standards. Purchasing your supplements from a reputable company with strict sourcing and production standards is money well spent.

No level of lead exposure is considered safe. Lead is distributed to your brain, liver, and kidneys and accumulates in your teeth and bones over time. Once stored in the bone, lead will remain there for twenty-five to thirty years. Even low levels of lead may cause osteoporosis, cognitive problems, and hearing loss. Chronic exposure to low levels of lead has also been shown to cause hypertension and cardiovascular disease.

Most lead dust we inhale gets absorbed into the lower respiratory tract. The liver can’t metabolize inorganic lead, so it must be bound by bile in the intestines and excreted or it will be absorbed into our tissues.


Mercury, a potent neurotoxin, is at the root of a wide variety of disorders. There is no known “safe” level of mercury exposure. We are exposed to mercury mainly through dental amalgams, fish and seafood (especially larger fish, such as tuna, swordfish, mackerel, and sea bass), medications, personal care products, agricultural chemical residues, and high-fructose corn syrup.

Mercury causes demyelination of nerve fibers (damage to the nerves’ protective myelin sheath) and slowing of the nerve conduction velocity. Mercury can also cause tinnitus and hearing loss, among other commonly recognized age-related illnesses.

Although many (not all) dentists now use safer composites, those of us who received a mouthful of silver amalgam mercury fillings during our younger years often still have them. And these fillings have slowly been leaking one of the most poisonous substances on the planet—mercury—into our body ever since, representing 50 percent or more of an adult’s mercury exposure. If you still have amalgam fillings, it’s imperative that you seek the advice of a biological dentist trained in safe mercury removal.
