Insulin – King of the Hormones

There is a single important chemical in the body which manages a variety of processes and levels in the blood and the entire body.  This single master control – the king in your hand – is called Insulin, and controlling your Insulin is the key to your health.
When I was 75 pounds heavier, I was not in control of my Insulin levels. I was significantly heavier. I always feeling tired and run down. I was snoring and even stopped breathing at multiple times during the night (a condition called Sleep Apnea). I felt like I needed high calorie, high sugar and caffeinated foods to give me an energy boost at every meal and even between meals. I was not in control of my Insulin, and this was messing with the rest of my bodily functions.

Hormones are chemical messengers produced by certain organs and cells in our body. They are stimulated and secreted in order to maintain a balance of many factors related to metabolism, stress and energy production. This balance is called “Homeostasis”.

Insulin is considered the “master hormone” of the body. It is a chemical messenger which is produced and secreted by cells of the Pancreas (Beta-cells) in response to eating food, but most notably, in response to carbohydrates. Insulin facilitates the movement of all macronutrients (protein, fat and carbohydrates) out of the bloodstream and into our cells for use either immediately, or in the future.

When we eat a meal high in carbohydrates (sugar, cereal, pasta, breads, rice), our body responds to the elevated level of sugar in our blood by releasing a wave of Insulin in the bloodstream, telling the cells to remove all this sugar from the blood and take it into the cells for energy production and/or storage. If this happens occasionally in the body, the response will occur properly. When we are eating high carb meals multiple times per day, our blood sugar levels remain chronically high and insulin needs to be produced constantly in order to keep levels within the normal range. When our insulin levels are constantly high, the constant knocking at the door by Insulin annoys our cells.

If a friend rings your doorbell or knocks on your door asking for a favour, you generally have no problem and will help them out. Now imagine that same friend constantly knocking at your door, 3-4 times per day, asking you to help them with this or that. Initially you would get annoyed. Soon, you may not even answer the knock at the door because this friend is asking for too much and is being incredibly annoying, and so you become less friendly and the favour doesn’t get completed.
The same thing happens in our cells when Insulin is constantly knocking at the door, asking for our cells to do them a favour by taking in some sugar from the bloodstream. Our cells eventually stop answering the knock at the door (Insulin Resistance). This can eventually lead to chronically high blood sugar levels (hyperglycaemia), which is harmful to our long-term health. The pancreas eventually stops producing insulin because our body stops reacting to it. We have lost our master hormone so our body’s hormone system. Our body reacts by many other hormones going out of balance including Glucagon, Cortisol, Thyroid, Testosterone, Progesterone, Estrogen and Leptin as well as their controlling hormones.

Chronically high blood sugar is a major cause of health conditions, including obesity, diabetes, heart disease, stroke, brain and memory conditions (read the book “Grain Brain”), Polycystic Ovarian Syndrome, and low sex drive.

Overcome these issues by eating meals higher in natural sources of carbohydrate and other micronutrients like dark, leafy green vegetables, carrots, tomatoes, and mushrooms. Your diet should also be higher in good quality protein like free-run eggs, chicken and wild-caught fish as well as good quality fats like avocado, nuts and seeds. Cook in coconut oil, ghee or butter and avoid low quality industrial oils. Feel free to sprinkle your salads with Olive Oil and Balsamic Vinegar as well rather than packaged dressings.

Stack your deck by treating the King of the Hormones well. Keep insulin working correctly and cells responding to that friendly neighbour. If you treat it will, your outlook will improve immensely as health will no longer limit you.

The Dark Side Of Kale (And How To Eat Around It)

The Dark Side Of Kale (And How To Eat Around It)

 Rachel Zimmerman

The headline in The New York Times made my heart sink: “Kale? Juicing? Trouble Ahead.”

Confession: I’m one of those Vitamix-loving, green-smoothie worshipping, kale bandwagoners. I brim with holier-than-thou pride when my kids eat raw kale (no dressing, even!) and thick kale-laden shakes while other children snack on sugary GoGURT squeezes and suck on juice boxes.

I am not alone. Presidents and stars are kale-lovers too.

Kale, in case you haven’t noticed, is health-conscious America’s “it” vegetable. Raw, blended, sauteed or in chip or “crunch” form, it appears to be the manna of celebrities: Gwyneth and Jennifer devour it while Kevin Bacon recently declared [it's] “the age of kale.” In an astutely reported feature called “Stars Who Love Kale,” US Weekly quotes Bette Midler saying: “Kale is burning up the veggisphere.”

Even the Obamas dined on kale salad at their Thanksgiving feast, notes The Washington Post.

But apparently there’s trouble in cruciferous paradise.

Writing for The Times, Jennifer Berman reports on the dark side of kale, and how the health-infused, veggie Eden she’d carefully built over years began to crumble:

Imagine my shock, then, at my last physical, when my doctor told me I had hypothyroidism, common in women over 40. When I got home I looked up the condition on the Internet and found a list of foods to avoid. Kale, which I juiced every morning, tops the list, followed by broccoli, cauliflower, cabbage, Brussels sprouts and collard greens — the cruciferous vegetables I consumed in large quantities because they are thought to prevent cancer, which runs in my family. And flax — as in the seeds — high in omega 3’s, that I sprinkled on cereal and blended in strawberry almond milk smoothies. Also forbidden: almonds and strawberries, not to mention soy, peaches, peanuts, corn, radishes, rutabaga and spinach.

My first reaction: Berman must be misguided, mistaken. Can kale possibly be bad?

Well, yes, possibly. Here’s the science-y lowdown on the kale-thyroid connection from the Oregon State University Micronutrient Information site:

Very high intakes of cruciferous vegetables…have been found to cause hypothyroidism (insufficient thyroid hormone) in animals (68). There has been one case report of an 88-year-old woman developing severe hypothyroidism and coma following consumption of an estimated 1.0 to 1.5 kg/day of raw bok choy for several months. Two mechanisms have been identified to explain this effect. The hydrolysis of some glucosinolates found in cruciferous vegetables (e.g., progoitrin) may yield a compound known as goitrin, which has been found to interfere with thyroid hormone synthesis. The hydrolysis of another class of glucosinolates, known as indole glucosinolates, results in the release of thiocyanate ions, which can compete with iodine for uptake by the thyroid gland. Increased exposure to thiocyanate ions from cruciferous vegetable consumption or, more commonly, from cigarette smoking, does not appear to increase the risk of hypothyroidism unless accompanied by iodine deficiency. One study in humans found that the consumption of 150 g/day (5 oz/day) of cooked Brussels sprouts for four weeks had no adverse effects on thyroid function.

(For an updated reality check on kale consumption and the thyroid, see our Q and A with endocrinologist and thyroid expert Dr. Jeffrey Garber here. Bottom line: in the U.S, where we don’t have a big problem with iodine deficiency, it’s probably OK.)

Teresa Fung, Sc.D., M.S.. an adjunct professor of nutrition at the Harvard School of Public Health and a professor at Simmons College in Boston, confirms the kale-thyroid link. But, she says, “normal, reasonable amounts of eating should not be a problem. A regular person [with no thyroid issues] who eats several servings of cruciferous vegetables a week should not have problems.”

Fung adds: “It’s the dose that makes a poison. If people have hypothyroidism or they’re taking thyroid medication, then they should check with their doctor. But even in this case, reasonable amounts shouldn’t be a problem. Now, if people have a tall glass of kale juice every single day, then it gets into the unknown territory.”

So, what are still-anxious kale-lovers to do? I asked Somerville, Mass. health coach and psychology of eating coach Nina Manolson to offer some guidance. (She’s not a doctor, but she knows a lot about food, so keep that in mind and always check with a professional if you make major changes in your diet.)

Nina reiterated that kale is a goitrogenic food, meaning that it can contribute to an enlarged thyroid — a goiter. A goiter indicates that the thyroid gland is not functioning optimally. But, she says, there are ways to have our kale and eat it too. Here, lightly edited, are her suggestions:

1. Cook Your Kale

The goitrogenic properties of kale become dramatically lessened when kale — or any other cruciferous vegetable — is cooked. (Other veggies in this category include: broccoli, brussel sprouts, cabbage, cauliflower, collard greens, kohlrabi, mustard, rutabaga, turnips, bok choy and Chinese cabbage. Arugula, horseradish, radish, wasabi and watercress are also cruciferous vegetables.)

2. Eat Seaweed

Kale on its own does not increase the risk of thyroid problems. It’s a combination of factors; including potential iodine deficiency. (One of the most common causes of goiters is iodine deficiency.) Adding seaweed or another iodine rich food to your diet may, in some cases, help you get adequate iodine.

3. Throw A Brazil Nut Into Your Smoothie

Selenium can support normal iodine levels which in turn may support a healthy thyroid. A Brazil nut or two in your daily smoothie or as a topping to any dish might help keep selenium levels strong.

4. Switch Up Your Greens

Vary your greens. If you’re going to eat kale one day choose a non-cruciferous, non-goitrogenic veggie dish the next, like a simple cucumber and tomato salad, or beets. There are many highly nutritious vegetables that aren’t goitrogenic, including celery, parsley, zucchini, carrots and more. Our bodies need many nutrients and by eating a variety of vegetables you’ll ensure that you don’t overload on one and skip another.

Nina adds:

If you don’t have a thyroid issue, kale can and should be a delicious and healthy part of your diet because it is, indeed, a nutritional superstar with excellent credentials:

•It supports strong bones because of its high calcium content.

•It’s a potential immune booster, rich in Vitamin C.

•It may protect us against cancer because it’s packed with antioxidants and as mentioned, it’s a cruciferous vegetable.

•It’s high in iron which can support blood and energy levels.

•And of course, it’s packed with fiber so it’s great for digestion.

All of this leaves me wishing that eating were just, well, simpler. With no arsenic in the rice and no flip-flopping guidance on milk, soy, whatever, from the experts.
