What’s more synonymous with summer than fresh watermelon? As the temperatures rise and summer makes its debut, there’s nothing better to satisfy our need for extra hydration and antioxidants. I invite you to get creative with this refreshing fruit by trying this tasty salsa that pairs well with just about any protein. – Fish tacos are a hit at my house, but you can serve with grilled chicken, tofu or shrimp. I make these tacos 10-Day Detox Diet and Blood Sugar Solution friendly by substituting taco shells with lettuce leaves.

Ingredients

Instructions

  1. In a medium bowl, combine the watermelon, avocado, onion, lime juice, zest, lemon juice, jalapeno and cilantro. Toss with the 1 tablespoon olive oil and ¼ teaspoon salt and set aside.
  2. Prepare a pan or grill to cook the fish. If using the grill, preheat to high and coat the fish on both sides with the remaining oil. If using a pan, heat the remaining oil over medium heat.
  3. Sprinkle the fish with Dr. Hyman’s Special Seasoning and remaining salt. Cook the fish until opaque inside, about 5 minutes per side. When the fish reaches an internal temperature of 145 degrees, remove from heat and set aside to cool for about 5 minutes or until no longer hot, but still warm to the touch. Using a fork, break into big pieces.
  4. To serve, place two lettuce leaves on top of each other to make a sturdy base for the fish. Place about ¼ cup of fish on each lettuce wrap, top with a couple tablespoons salsa.
  5. Dr. Hyman’s Special Seasoning-
    When I’m in a hurry to cook but want a meal that will pack some flavor, I use a tablespoon of this special seasoning to impart great aroma, taste and color to a pound of fish or meat. Keep a 2-ounce jar mixed up of this and stash it in your spice cabinet for up to 6 months.

    Yields = a healthy 1/4 cup
    Prep Time = about 5 minutes
    Cook Time = 0 minutes

    Ingredients:

    1 Tablespoon Smoked Paprika
    1/2 Tablespoon Sea Salt

    Why the Revolution Starts in Your Kitchen

    The cure for what ails you isn’t just found with your doctor. You can also find it in your kitchen.

    Here, we can gather to rebuild our communities and connection, strengthen bonds with family and friends, teach life-giving skills to our children, and enrich and nourish our bodies and our souls.

    Today, our kitchens (and our taste buds) have been hijacked by the food industry. In 1900, we only ate two percent of our meals outside of the home. A century later, that number has risen to over 50 percent.

    The food-like substances proffered by the industrial food system trick our taste buds into momentary pleasure. But our biology rejects the junk forced on our genes and on our hormonal and biochemical pathways.

    Your tongue can be fooled and your brain can become addicted to the slick combinations of fat, sugar, and salt pumped into factory-made foods, but your biochemistry cannot handle these foods, and the result is the disaster we have in America today.

    According to the Centers for Disease Control and Prevention (CDC), 69 percent of American adults are overweight and 35 percent are obese. Far from simply becoming aesthetically unappealing, studies show being obese increases our risk for numerous conditions, including heart disease, stroke, type 2 diabetes, high blood pressure, and cancer.

    It can also be deadly. About 3.4 million adults die each year from being overweight or obese, and type 2 diabetes is the seventh leading cause of death among Americans.

    Our children are feeling these effects, too. In less than a decade, the rate of pre-diabetes or diabetes in teenagers has risen from 9 percent to 23 percent. In other words, almost one in four kids has pre-diabetes or type 2 diabetes.

    I could go on, but you get the very dismal point. We must take back our kitchens and our homes.

    Transforming the food industry seems like a gigantic undertaking, but it is in fact an easy fix. The power lies in our shopping carts, our refrigerators, and our cupboards—and on our dining room tables. It is the hundreds of small choices you make every day, choices that will topple the monolithic food industry.

    We need a revolution. Cooking real food is a revolutionary act.* We have lost the means to care for ourselves. We currently raise the second generation of Americans who don’t know how to cook. The average child in America doesn’t know how to identify even the most basic vegetables and fruit; our kids don’t know where their food comes from or even that it grows on a farm. Cooking means microwaving. Food “grows” in boxes, plastic bags, and cans. Reading labels is supremely unhelpful in identifying the source of most foods — the ingredients are mostly factory-made science projects with a remote and unrecognizable lineage to real food.

    We are brainwashed into thinking that cooking real food costs too much, is too hard, and takes too long. These seemingly inexpensive convenience foods aren’t so inexpensive or convenient when we become dependent on hundreds of dollars of medication each month, when we can’t work because we are sick and fat and sluggish, or when we feel so bad we can’t enjoy life anymore.

    The average American spends eight hours a day in front of a screen (mostly television) and spends more time watching cooking shows than actually cooking.
    Convenience is killing us.

    The truth is, real food can be inexpensive. Choosing simple ingredients, cooking from scratch, shopping at discount club stores like Thrive Market , and getting produce from community supported agriculture associations (CSAs), community gardens, or co-ops all build health and community and save money. Food is the best investment in your health.

    We need radical change to transform food. Each of us can play a part, and that change begins in the kitchen. Once you have taken back your kitchen, then you can start something really revolutionary.

    To help you with that transformation, I want to tell you about an amazing new cookbook my friends at Thrive Market have compiled with some amazing health experts.

    The Thrive Communal Table contains 60 delicious, easy-to-make, healthy recipes for breakfast, lunch, dinner, sides, and treats. With these recipes, you’ll have everything you need to take back your kitchen and win over your family. Best of all, you can get your cookbook FREE here.

    I’ve contributed several recipes to The Thrive Communal Table, including a guilt-free chocolate mousse that’s sure to get raves at your next dinner, as well as my favorite breakfast, my whole food protein shake.

    When people tell me they don’t have time for breakfast, I show them this shake recipe. It’s fast, easy, filling, and delicious. It includes wholesome ingredients like almond butter, pumpkin seeds, hemp seeds, and coconut butter. To save time and money, you can find these and other top-notch ingredients at Thrive Market (simply click the link to find that product, personally approved by me).

    Food Bites with Dr. Hyman – Crucifers and Thyroid

    Emilia A asks: Should I avoid foods like broccoli and kale if I have a thyroid issue?

    Dear Emilia:

    One of the top most misdiagnosed conditions people come to me for help with is their thyroid function, or lack thereof.  Unfortunately, many patients miss receiving proper diagnosis and care for their thyroid because the appropriate labs were never ordered.  Even more problematic, your symptoms plaguing your daily life as a thyroid patient may have been shrugged off as “normal.”  But when did unrelenting fatigue, stubborn weight loss, or depression become tolerable or normal?

    When I hear patients complain of stubborn weight loss, cravings, dry skin, acne or eczema, unexplainable fatigue, inability to focus or concentrate, problems with menstruation or fertility, or even abnormal metabolic lab results for cholesterol, iron, or blood sugar, I immediately question if their thyroid is properly functioning.

    There are many reasons why a large percentage of our population is suffering from a low functioning thyroid (and many who are under-diagnosed and are consequently suffering).  From environmental toxins like mercury which block active thyroid hormone from entering the cells through the receptor site, to low nutrient status which inhibits the conversion of the inactive thyroid hormone, T4, to its active form, T3, I use lengthy checklists and labs to assess an individual’s root cause of low thyroid.

    What I do not look for in these assessments, however, is if a person eats cruciferous vegetables and whether or not foods like broccoli, kale, collards, Brussels sprouts, radish or cabbage are the trigger for their hypothyroid or an autoimmune Hashimoto’s condition.

    Why not?

    There is a lot of chatter in the pop-nutrition culture saying that these vegetables have an ill effect on the thyroid because they contain goitrogens.  Goitrogens can block iodine from entering the thyroid and eventually cause a swollen thyroid or goiter.  Because iodine is critical for normal thyroid function, some believe that if you consume too many goitrogens, then your thyroid will not function properly, leading to an underactive thyroid.

    The active form of your thyroid hormone is called triiodothyronine – the “iodo” part of the word highlighting the significance of iodine in proper hormone function.  So you can see why people would be curious to know if foods containing substances (goitrogens) would block iodine from the thyroid and question if they should eliminate or at least eat them with caution.

    The truth is, you would need to consume a large amount of these vegetables for their goitrogenic constituents to have an impact on your thyroid.  Even more important is that you would have to consume them raw.  When was the last time you ate 10 cups of raw Brussels sprouts or blended up 5 cups of raw kale in your Dr. Hyman’s Whole Foods Protein Smoothie and consumed it every day?

    Exactly.

    Because most of us steam, lightly boil, roast, sauté or bake our cruciferous vegetables, the amount of goitrogens our body actually receives is that much less due to the effect cooking these foods has on active goitrogenic level.  So, my advice is not to worry about eating moderate servings of raw or cooked cruciferous veggies and to actually make a point of consuming 1 to 2 servings of them daily because they are so fundamentally crucial to disease prevention (especially cancer), as well as normal metabolic function (such as detoxification).

    If you are still concerned about how eating these vegetables affects your thyroid then follow some of these guidelines:

    1. Know the whole story. Cruciferous vegetables are not the only foods that contain goitrogenic substances.  Cassava (yuka), sweet potato, millet, soy, and even certain medications (such as Lithium) contain goitrogens.  The goal is not to demonize individual foods, but to eat a variety of foods in moderation.  Especially when studies repeatedly show that the goitrogenic substances in food are nothing to fear in terms of how they affect your thyroid function.
    1. Focus on the proven triggers for thyroid dysfunction. If we are to single out foods that specifically do impact your thyroid function then let’s spend time examining foods like sugar, gluten, conventional dairy foods, and processed soy.  All four have been researched and shown to negatively impact your thyroid.  One of the first suggestions I give newly diagnosed thyroid patients is to go 100% gluten free.  For more on the impact of gluten on thyroid function, read this article.
    1. Concentrate on what we can have! The best way to prevent your thyroid from crashing is not to eliminate healthy foods that are sensible parts of your whole foods diet (broccoli or kale), but to abundantly consume real, whole, nutrient-dense foods that contain copious amounts of thyroid-friendly nutrients (vitamins A and D, omega-3 fatty acids, B vitamins, selenium, tyrosine, and iodine).

    Consume more of these:

    Vitamin A: orange and yellow vegetables or dark leafy greens

    Vitamin D: look for a high-quality D3 supplement

    Omega-3 Fats: fatty fish like sardines and wild salmon; walnuts; and flax, chia, or hemp seeds

    B Vitamins: wild meat, poultry, eggs, green leafy vegetables, legumes

    Selenium: seafood, eggs, Brazil nuts

    Tyrosine: poultry, grass-fed dairy, avocado

    Iodine: sea vegetables (nori, wakame, etc.), seafood, grass-fed dairy

    1. Steam or cook your cruciferous veggies to decrease the amount of goitrogenic properties. Remember, however, that the longer vegetables are cooked, the more water-soluble nutrients (including disease-fighting phytonutrients) are lost in the cooking process.  Clearly, you want to steam or cook lightly and not for too long or at too high temperatures.  The ultimate goal is a mixture of raw and cooked vegetables.

    Bottom Line:  There are just too many important health benefits from eating cruciferous vegetables to think that tossing them from your healthy, whole foods diet makes sense.  The only time I would suggest monitoring your intake of them is if you have a known iodine deficiency coupled with advanced, uncontrolled hypothyroidism.  In that extremely rare case, please work with your local Functional Medicine provider to discuss the best supplement and diet to replenish your iodine levels and replete your overall nutrition and health status.

    If you are looking to use my food as medicine approach to take back your health, successfully manage your thyroid imbalances, and lose stubborn pounds as summer starts, please consider joining my next community-supported event, The 10-Day Detox Diet Challenge.   The fun starts June 18th, and I would love to have you join us!

    Wishing you health and happiness,
    Mark Hyman, MD.

    A Comprehensive 6-Step Strategy to Heal Your Thyroid

    As I explained in last week’s blog, the thyroid system plays a critical role in your metabolism. Along with insulin and cortisol, your thyroid hormone is one of the big three hormones that control your metabolism and weight.

    The key is the right testing to confirm that a sluggish thyroid is contributing to a stalled metabolism and other problems.  Once you know this for sure there are many ways to help correct thyroid problems.

    There are so many reasons for low thyroid function, yet I see many patients whose doctors have ignored this problem. One young female patient had more than 30 percent body fat and was unable to change her body, no matter how hard she worked. She ate perfectly, exercised with a trainer every day, yet her body wouldn’t budge. She also had a slightly depressed mood and other vague symptoms.

    I treated her with a low dose of Armour® thyroid, a natural thyroid replacement.

    What happened?

    Well, she lost 20 pounds and improved her body composition and mood. And all of her other symptoms went away.

    How did I know she and other patients had low thyroid function? I ask about symptoms, perform a physical exam, and consider potential causes of thyroid problems. Then I do the right tests.

    Most doctors just check something called thyroid-stimulating hormone (TSH), which doesn’t give a full picture of the thyroid. In fact, even the interpretation of this test is incorrect most of the time.

    The newer guidelines of the American College of Endocrinology consider anybody with a TSH level over 3.0 as hypothyroid. (1) Most doctors think that only anything over 5 or 10 is worth treating. Unfortunately, this leaves millions suffering unnecessarily.

    Besides TSH, Functional Medicine practitioners perform other essential tests including free T3, free T4, and thyroid antibodies. We also look for associated problems such as gluten intolerance, food allergies, and heavy metals, as well as deficiencies of vitamin D, selenium, vitamin A, zinc, and omega-3 fats.

    Last week I provided some strategies to address underlying causes of hypothyroidism. Here, I want to dive a little deeper to address some strategies to heal your thyroid.

    Correcting these problems requires an integrative approach. It involves more than simply taking a thyroid pill. As you’ll see, it involves nutritional support, exercise, stress reduction, supplements, reducing inflammation, and sometimes eliminating certain foods and detoxification from heavy metals (such as mercury and lead) and petrochemical toxins (such as pesticides and PCBs).

    To integrate all of these elements and create a successful set of techniques to cope with your thyroid problems, I recommend these six strategies.

    Strategy 1: Eliminate the causes of thyroid problems.

    Carefully consider things that may interfere with your thyroid function and eliminate them. As you will see, there are a good many things that can impede optimal thyroid function.

    Diet is a good place to begin. Certain foods have developed a reputation for playing a role in thyroid dysfunction, but this reputation isn’t necessarily connected to the latest scientific evidence.

    For instance, soy foods and the broccoli family (broccoli, cabbage, kale, Brussels sprouts, and collard greens) have all been said to cause thyroid dysfunction, but they also have many other health benefits. Research on these foods to date has been less than conclusive. In one study, rats fed high concentrations of soy had problems with their thyroid.

    The take-home message: If you are a rat, stay away from tofu. Human studies have shown no significant effect when soy is consumed in normal quantities. (2)

    On the other hand, there are food groups where substantive evidence supports a link to an autoimmune disease of the thyroid that slows down your metabolism.

    Gluten is one of them. (3) If you think you are having a thyroid problem, you need to do a blood test to identify any hidden reaction to gluten found in wheat, barley, rye, oats, kamut, and spelt. Gluten sensitivity or allergy can cause many different types of symptoms, from migraines to fatigue to weight gain.

    Besides doing the blood test, you can simply eliminate gluten from your diet for three weeks. If your symptoms go away, you have a clue that your system might not like this food. If you want to take this self-test a step further, reintroduce gluten into your diet and see if your symptoms recur. If they do, that is another major clue.

    There are other food allergies besides gluten that can stall thyroid function. You might want to work with a medical practitioner to pinpoint and eliminate these food allergies. A good place to begin is my book The Blood Sugar Solution 10-Day Detox Diet.

    Besides certain foods and food allergies, toxins can slow down your thyroid. Testing yourself for mercury and getting it out of your system and your environment becomes crucial. (4) You also want to avoid fluoride, which has been linked to thyroid problems, (5) and chlorinated water.

    Checking for pesticides is more difficult, but supporting your body’s detoxification system by eating organic foods, filtering your water, and eating detoxifying foods can be very helpful to heal your thyroid.

    Stress also affects your thyroid function negatively. Military cadets in training who were subjected to intense stress had higher levels of cortisol, higher inflammation levels, reduced testosterone, higher TSH, and very low T3. Treating the thyroid without dealing with chronic stress can precipitate more problems.

    A common form of chronic stress – adrenal gland exhaustion or burnout – particularly becomes dangerous for hypothyroidism. Adrenal gland exhaustion occurs when your adrenal glands are unable to keep up with the physiological needs created by stress.

    To remedy this chronic stress, incorporate what I call active relaxation. You might also consider my UltraCalm CD to melt away stress and anxiety.

    Strategy 2: Regular Exercise and Saunas

    Exercise stimulates thyroid gland secretion and increases tissue sensitivity to thyroid hormones throughout the body. Ideally, you will want to sweat, and the exercise should be vigorous. Regardless of your current fitness level, you will find a helpful, easy-to-implement workout plan here.

    Besides being an excellent way to relax your muscles and your mind, saunas or steam baths are a good way to flush your system of pesticides that could be contributing to your thyroid problem.

    Saunas are an important aid to weight loss and thyroid repair because as you lose weight, fat tissue releases stored toxins such as PCBs and pesticides (organochlorines). (6) These toxins lower your T3 levels, consequently slowing your resting metabolic rate and inhibiting your fat-burning ability. (7)

    Detoxifying becomes an important part of improving your thyroid function. If you don’t detoxify, your ability to lose weight decreases as you lose weight because of the released toxins’ detrimental impact on thyroid function.

    Strategy 3: Eat Foods That Provide Nutritional Support for Your Thyroid, and Avoid Those That Don’t

    Every step on your road to healing and weight loss depends on proper nutrition and using food to communicate the right information to your genes. (8) Treating your thyroid is no exception.

    Choose foods that offer nutritional support for your thyroid.  The production of thyroid hormones requires iodine and omega-3 fatty acids; converting the inactive T4 to the active T3 requires selenium; and both the binding of T3 to the receptor on the nucleus and switching it on require vitamins A and D, as well as zinc. You will find these nutrients in a whole-food, clean, organic diet. To get therapeutic levels of these nutrients, please use the supplement protocol in strategy 4.

    Thyroid-boosting foods include seaweed and sea vegetables, which contain iodine. Fish (especially sardines and salmon) contains iodine, omega-3 fats, and vitamin D. Dandelion, mustard, and other dark leafy greens contain vitamin A. Smelt, herring, scallops, and Brazil nuts contain selenium.

    You want to avoid foods that can interfere with thyroid function. These include the aforementioned gluten. Also, choose clean sources of soy protein in moderation and avoid processed soy products.

    Strategy 4: Use Supplements That Support Your Thyroid

    Key nutrients for healthy thyroid function are included in my basic supplement recommendations, including a multivitamin and mineral supplement that contains selenium, iodine, zinc, vitamins A and D, and omega 3 fats (fish oil). You will find all these nutrients at my store, as well as a thyroid support kit.

    One warning is that if your adrenal glands are burned out from long-term stress, treating the thyroid without supporting the adrenal glands through relaxation and adaptogenic herbs (such as ginseng, rhodiola, or Siberian ginseng) can actually make you feel worse.

    I also recommend working with an experienced practitioner who can address individual nutrient needs for your thyroid and, if necessary, also your adrenal glands.

    Strategy 5: Have Your Thyroid Tested

    There is no one perfect way, no one symptom nor test result, that will properly diagnose low thyroid function or hypothyroidism. The key is to look at the whole picture – your symptoms and your blood tests – and then decide.

    Doctors typically diagnose thyroid problems by testing your TSH levels and sometimes your free T4 level. But some doctors and clinicians have brought the “normal” levels of those tests into question.

    The diagnosis of “subclinical” hypothyroidism that I discussed last week depends on having a TSH level higher than 5 m IU/ml and lower than 10 m IU/ml. As I mentioned above, new guidelines suggest anything over 3 is abnormal. While an improvement, practitioners following these guidelines may still miss many people who have normal test results and a malfunctioning thyroid system.

    To get a complete picture, I recommend looking at a wider range of functions:

    • Thyroid-stimulating hormone (TSH), the ideal range is between 1 and 2 m IU/ ml
    • Free T4 and free T3 (the inactive and the active hormone)
    • Thyroid antibodies (TPO), looking for an autoimmune reaction that commonly goes undiagnosed if the other tests are normal, as doctors don’t routinely check this
    • Thyroid-releasing hormone (TRH) stimulation test
    • A 24-hour urine test for free T3, which can be helpful in hard-to-diagnose cases

    A physician experienced in ordering these tests and interpreting the results can provide a more comprehensive picture of how your thyroid is functioning.

    If you think you have an undiagnosed thyroid problem, insist that your doctor perform these tests or find a doctor who will. They are essential to fill in the pieces of the puzzle standard tests don’t provide.

    Strategy 6: Choose the Right Thyroid Hormone Replacement

    Ultimately, to properly balance a thyroid that is severely out of balance, you will need to go on some type of thyroid hormone replacement therapy.

    Altering your diet and your lifestyle will certainly help tremendously, but if your thyroid isn’t functioning properly, you may need to take some additional thyroid hormones to supplement its output. Knowing what’s available and what to ask about can empower you to make better decisions about your health.

    When I went to medical school and did my residency, I learned about only one treatment for low thyroid function: Synthroid®, a synthetic form of T4 that wasn’t FDA-approved until recently.

    Why do doctors prescribe it? Because that is all they learn to prescribe. But that doesn’t make it the best treatment for everyone. Some people benefit from Synthroid, but in some cases the symptoms don’t seem to go away using only T4, even if their tests return to normal. So what is the right treatment?

    The answer is, it depends.

    Part of the beauty (and the headache) of Functional Medicine is that no one treatment works for everyone. A combination of experience, testing, and trial and error becomes necessary to get any treatment just right.

    At the same time, I’ve discovered the majority of my patients benefit from a combination hormone treatment including both T4 and T3. Synthroid is just T4, the inactive hormone. Most doctors assume that the body will convert it to T3 and all will be well.

    Unfortunately, pesticides, stress, mercury, infections, allergies, and selenium deficiencies can block that process. Since 100 percent of us have pesticides stored in our bodies, we will all likely have some problem with Synthroid.

    The most common treatment I use is Armour thyroid, (9) a prescription drug made from desiccated (dried) porcine thyroid. It contains the full spectrum of thyroid hormones, including T4, T3, and T2 (10). That last one – T2 – is a little-known product of thyroid metabolism that actually may be very important. The right dose ranges from 15 to 180 milligrams, depending on the person.

    Many doctors still hold the outdated belief that the preparation is unstable and the dosage difficult to monitor. That was true with the old preparation of Armour, not the new one. (See http://ift.tt/1MJdKpW for more information.)

    Sometimes the only way to find out if you have a thyroid problem is a short trial of something like Armour thyroid for three months. If you feel better, your symptoms disappear, and you lose weight, it’s the right choice. Once started, you needn’t take it for life.

    Sometimes, once all the factors that disturbed your thyroid function have been corrected, you may be able to reduce or discontinue the dose. As with any treatment, always work with a physician experienced in using medications to treat your thyroid.

    Careful monitoring is essential. Taking too much thyroid hormone or taking it if you don’t need it can lead to undesirable side effects, including anxiety, insomnia, palpitations, and, over the long term, bone loss.

    Conclusion 

    Over my several decades working as a Functional Medicine doctor, I can assure you that even in the toughest cases, you can heal your thyroid. With some patients, I can do this through the dietary, nutrient, and lifestyle factors I’ve discussed here. For others, that healing requires trial and error using several medications and working closely with a physician.

    The bottom line is that you should never lose hope. Taking a proactive approach and working with a trained practitioner can correct many thyroid issues.

    Tethys the Target


    Like most moons in the solar system, Tethys is covered by impact craters. Some craters bear witness to incredibly violent events, such as the crater Odysseus (seen here at the right of the image). The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 11, 2015.

    Fresh Crater Near Sirenum Fossae Region of Mars


    The HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter acquired this closeup image of a “fresh” (on a geological scale, though quite old on a human scale) impact crater in the Sirenum Fossae region of Mars on March 30, 2015. This impact crater appears relatively recent as it has a sharp rim and well-preserved ejecta.
