What is the deal with Nightshades?
What is the deal with Nightshades? When I hear the word nightshade, I immediately think of poisonous plants used by evil witches in fairy tales from long ago! Belladonna, of course, comes to mind mostly, not to be confused with the incredible album, “Belladonna”, released by the good witch, Stevie Nicks, in 1981. Anyway, nightshades aren’t exactly poisonous but can be harmful to some. They encompass a whole entire family of flowering plants and you probably eat some daily. Some of the most popular being tomatoes, potatoes and peppers. Why are nightshades ‘bad’ for you? Nightshades contain several chemical compounds that can have negative effects. The worse ones are glycoalkaloids, capsaicin, calcitriol, nicotine, and saponins. These compounds are part of an amazing self defense system protecting the plant from predators, unfortunately they can also have a negative response in our bodies resulting in inflammation and other problems. For example glycoalkaloids, have been shown to cause leaky gut and overall inflammation in the gastrointestinal system. They also block valuable enzymes resulting in overstimulation of the nervous system causing anxiety. One 2005 study showed that it took 24 hours for this compound to be eliminated from the body, so if you’re eating nightshades daily, there’s a possibility of toxic overload. Capsaicin has been linked to respiratory issues and because some measure quite high in the Scoville scale, they can irritate bodily tissues and the stomach lining. Calcitriol, when consumed in high amounts, can result in calcium deposits in soft tissue, heart and kidney. Saponins has been shown to interfere with the cellular membrane, actually creating holes in the membrane which diminishes cellular function. Lastly, all nightshades contain nicotine, which can make some foods potentially addictive. Also nicotine has been known to interfere with healing of wounds. All the medical jargon and studies aside, when we discuss elimination diets overall, it’s true, the heavy hitters are gluten, dairy, corn and eggs. Nightshades tend to be less of a problem, but if you are experiencing inflammation or digestive issues, it’s worth looking into. The best way to find out is by avoiding all nightshades for at least 3 weeks then eating them twice a day for 2 days and assessing, how do you feel? At Tao to Wellness, we offer a total detox and elimination diet program and include nightshades on that list, you can do the program anytime, but every Spring, we lead a group together and it’s super fun! Here is a complete list of nightshades Ashwagandha BBQ sauce Capsicums Cayenne pepper Chili Pepper Flakes Chili powder Chinese Five-Spice Powder Curry Powder Curry spice powder Eggplants Goji berries (also known as Wolfberries and found in Chinese herbal formulas) Gooseberries Hot Sauce Ketchup Paprika spice Peppers (including bell peppers, sweet peppers, chili peppers, jalapeños) Pimentos Potatoes (does not include sweet potatoes or yams) Red Pepper Red Pepper Flakes Sorrel Steak Seasoning Tomatillos Tomatoes Let’s end this on a good note, SWEET POTATOES and BLACK PEPPER are not nightshades, so continue to enjoy!

The Caffeine Conundrum
The Caffeine Conundrum There you are: you wake up in the morning, maybe a bit groggy from the night’s slumber (yawn); where’s that coffee?! Or maybe it’s 3pm and you have two or three more hours of work – EEEEK! How will you get through? Afternoon tea, chocolate, energy drink or more coffee? Anything that possesses that magical chemical called CAFFEINE! Worldwide, we reach for caffeine to help alter our sleep/wake cycle, but how does it do that and is that the best idea in the long term? Is there another option? A lot of my patients say, “but I only have one small cup in the morning”. Some admit, “I cannot function without coffee and I drink 5 cups a day…” then add “but it doesn’t effect me”. Still others say, “It’s the ritual and the taste that I love!” Everyone has totally valid reasons to love caffeine. It tastes good, it’s a ritual, it’s a necessity, right? So, let’s break it down; what’s actually happening when you drink or eat caffeine? The Effects of Caffeine on the Body Adenosine Let’s talk about Adenosine first. Adenosine is the by-product of cellular processes, and this molecule conducts the sleep/wake cycle; and caffeine looks just like it structurally. After you drink or eat caffeine, it gets absorbed by the small intestine and dissolved into the bloodstream. And since caffeine is both water and fat soluble, that means it can penetrate the BBB (blood brain barrier) and enter the brain. While it’s in the brain, it neatly fits into the brain cells’ receptors that are available for adenosine (remember because they look alike), essentially blocking them, which creates a sense of alertness and energy for a few hours – maybe up to four! So regardless of your natural circadian rhythm, you ‘wake up’ from the caffeine. In addition to that, two other things start happening. The pleasure center in the brain gets pinged and dopamine gets released, which makes us alert, focused, motivated and happy. And secondly, since we have all this extra adenosine floating around the brain, that signals your adrenal glands to secrete adrenaline, which is yet another stimulant. It’s a triple threat! Scientists say that caffeine isn’t just a stimulant on it’s own; “a stimulant enabler, it’s a substance that lets our natural stimulants run wild”, says Stephen R. Braun, the author of Buzzed: the Science and Lore of Caffeine and Alcohol. Dopamine Basically, dopamine is released when your brain is expecting a reward or has what it perceives to be a reward. When dopamine is released we feel awake, focused and happy. Yes, caffeine or even alcohol can be a reward, but only because we have trained our brain to believe that is the truth; remember, I said “what it perceives to be a reward”. To understand the dopamine release better, let’s talk about Skinner’s Box. Back in the 1950s, a scientist named Skinner put electrodes in the feeling centers of rats’ brains and sent a little shock to the area when a rat entered a particular corner of the box; the theory was if the shock was painful enough, the rat would stay out of that corner: enough shocks and the rat’s brain would hardwire the corner as adverse. Yet when the electrode was placed in the nucleus accumbens, which is a dopamine pathway, the rats did just the opposite; hungry for more and more dopamine release, they returned to the corner again and again, up to 700 times per hour! They even chose the stimulation over food. So the thing to consider is: are we like Skinner’s rats – have we hard wired our brains to think caffeine is all that, or can we get a dopamine hit from somewhere healthier? Another interesting thing to know is that dopamine doesn’t just get released when that ‘thing’ pings that area of the brain, but that dopamine starts getting released when we are merely thinking or anticipating the reward. Meaning as soon as we start to think about having the coffee, the happy hour cocktail or smell fresh bread while walking past the bakery, our brains are already releasing dopamine; essentially tricking us, because when we get it, we are even more excited and think this is the thing that makes me happy! Which of course is not the truth. Dopamine or the dopamine reward system isn’t the problem; the problem is how we stimulate the dopamine pathway. The things that stimulate the pathway can run the gamut; caffeine, alcohol, drugs, cigarettes, falling in love, sex, Netflix, pornographic videos, shopping, gambling, yoga, meditation, healthy eating, etc. Some of these things can be viewed as ‘positive’ and others ‘negative’ if you will, but really anything in excess can be harmful. So if we can make anything light up our dopamine pathway, so why not choose the good stuff? But is Caffeine Really That Harmful? The obvious risk is because caffeine is habit forming. Over time, the brain’s chemistry and physical characteristics actually change and you are no longer accessing your body’s natural energy resources. The most notable change is that brain cells actually grow more adenosine receptors. It’s the brain’s masterful way to maintain equilibrium in the constant onslaught of caffeine. It explains why regular coffee drinkers build a tolerance over time; since it takes more caffeine to keep up with the body making more adenosine receptors, it takes more caffeine to reach the desired effect. Maybe it’s not so much of the what the harm is, as much as it is – what we are giving up by being a slave to caffeine? What Are the Symptoms of Caffeine Withdrawal? When patients decide to quit caffeine for good or temporarily, the sudden giving up of caffeine can trigger a whole slew of symptoms. The most common symptoms are fatigue and headaches, which make complete sense. Basically, your brain is used to operating in one set of conditions that depend on caffeine and now that’s gone. So, there is
