Essential Nutrients for Fighting the Cold and Flu

Strengthen your own immune system and give your body the natural ability to fight any bacteria, virus, or microbe. 


You see the signs at every pharmacy, and the doctor asks every time you check in: “Have you had your flu shot?” Though November and December are prime months for flu season, you can really catch the flu at any time, so better be prepared, right? Well, there are a number of reasons why one should reconsider getting a flu shot.
 
Flu shots contain mercury. Mercury is one of the most hazardous neurotoxins because it destroys brain tissue. Easily destroys brain tissue. A common urban myth is that the mercury has been taken out of vaccines. This is not true. Several of the flu vaccines contain a neurotoxic ingredient called thimerosal. This is a fancy term for mercury.
 
The purpose of the flu shot is to assist the body’s ability to fight specific strains of flu. However, the problem here is that every year, the influenza viruses in the seasonal flu vaccine are selected through calculations about what flu viruses are most likely to cause illness in the coming season. The FDA, acting in concert with the CDC, decides which influenza vaccine strains should be sold in the U.S. Do you know how the flu strain is picked to put into the vaccine every year? The “experts” guess.
 
Instead of getting a flu shot, which is both ambiguous and dangerous in what it has to offer, why not strengthen your own immune system and give your body the natural ability to fight any bacteria, virus, or microbe?

Most folks who contract the flu already have a subclinical deficiency of a nutrient, which means that the body cannot function at optimal performance. Add emotional stress, weather changes, and/or daylight changes to the borderline deficiency and we have the recipe for a body functioning at a lower performance level. The result is that bacteria and viruses gain temporary control--we call that the cold or the flu.
 
Two major nutrient deficiencies that I test for in my clinic are zinc and vitamin D because both of these nutrients play a critical role in warding off colds and flus.
 
Zinc is crucial for a healthy immune system and is a co-factor in over 200 enzyme systems. We need zinc to make proper amounts of hydrochloric acid HCL (see my blog Got Heartburn?). Zinc is also necessary for so many other functions:

  • Improves of cardiovascular function
  • Supports female and male reproductive health
  • Increases wound healing
  • Produces healthy skin cells
  • Stimulates GI cell repair
  • Reduces inflammation
  • Creates healthy cell membranes
  • Metabolizes essential fatty acids (Omega 3/6)
  • Produces white blood cells
 
Zinc has a direct link to our body’s T-cells. If the body has a proper level of zinc, helper T-cells orchestrate an immune response and play important roles in all arms of immunity. Killer T-cells hunt down and destroy cells that are infected with germs or cells that have become cancerous. However, low zinc produces a direct and rapid decline in T-cell function in both helper and killer. Four out of five people I test in my office for zinc deficiency have suboptimal levels. Unfortunately, our soil and water is devoid of minerals and, therefore, so are we.
 
Vitamin D is another crucial nutrient that aids in building a healthy immune system, and almost everyone is deficient in it. Vitamin D, which is more like a hormone than a vitamin, is responsible for the regulation of over 2,000 genes in our body. Like zinc, Vitamin D has many roles in the body:
  • Maintains blood sugar
  • Supports a healthy gut
  • Reduces inflammation
  • Activates the immune system against microbes
  • Alkalizes pH
  • Maintains healthy bone mass
 
Vitamin D is a fat soluble vitamin along with Vitamins A, E, and K. Vitamin D should be taken with fat at your largest meal of the day.
 
Studies show that Vitamin D helps the body make more glutathione in both the liver and the brain. Glutathione is the body’s master antioxidant and without it we are not able to detox metals, toxins, or chemicals. In scientific studies, when subjects were given Vitamin D, glutathione production was increased, however, those who had a zinc deficiency had the lowest increase [1]. Glutathione, the master antioxidant, outweighs the importance of any antioxidant you can take by mouth. It affects every system in the body, especially the immune system, the nervous system, the GI system and the lungs. Glutathione cannot be taken as a supplement; it must be made in the body.
 
Another vitamin worth mentioning when talking about the flu is vitamin C. Most people know that vitamin C is great for combating the common cold, unfortunately many people lack the enzyme that is required for the last step of Vitamin C synthesis. The body will make-do by recycling the oxidized version of vitamin C, but in order to complete synthesis, glutathione must be present.
 
Additionally, most people get their vitamin C from fruit or juice (i.e. consume more sugar), which places the uptake of vitamin C in direct competition with the uptake of sugar by the cell. This is due to what is known as the Glucose Ascorbate Antagonism (GAA) theory. The GAA was aptly named in the 1970’s when Dr. John Ely discovered that glucose and vitamin C (ascorbate) have a very similar chemical makeup. When glucose levels are elevated, they compete with, and effectively restrict, vitamin C from entering the cells. Blood glucose levels become elevated by eating sugar, or if the body is insulin resistant and diabetic. Both glucose and vitamin C depend upon the pancreatic hormone insulin and its signaling effects in order to get into the cells. This means that the greater the amount of circulating blood sugar, the less vitamin C will enter the cells. This is one of the many ways that sugar dampens our immune system and why we face more colds and flu during the highest sugar-consumption season of the year: Halloween through Valentine’s Day.
 
The most effective way to combat disease and illness is not necessarily through a flu shot. You need to develop a wellness program that includes a whole food diet and a professional grade supplement regime year round to help support optimum nutrition. Exercise, even moderate, is also key--get and keeps everything moving! Make your body its own best defense, without pumping a bunch of “guesswork” vaccines into it.

What you should know about heavy metal detox if you have an autoimmune disease.

When it comes to autoimmune conditions, many of my clients are eager to find answers about the foods that could be triggering their symptoms. They often think, "If I just avoid certain foods, I’ll feel better." But, what they might not realize is that food combinations can play a huge role in causing autoimmune flare-ups, even when the individual ingredients don’t show antibodies on their own. It’s a tricky and often frustrating area of functional medicine, but understanding it is key to healing. Here's what you need to know. Understanding Food Protein Reactions Let’s start with the basics. In a perfect world, food sensitivities and allergies are pretty straightforward. You eat a food, your body reacts, and you know exactly what caused the problem. Unfortunately, with autoimmune disease, the story is more complex. As a functional medicine practitioner trained under Dr. Datis Kharrazian, I don’t just look at individual foods—I look at immune response. And food proteins can behave very differently when combined. You may have a test that shows no antibodies for specific foods, think chicken, potatoes, or broccoli. But when those foods are cooked together in a meal, something changes. The proteins in those foods could combine in a way that causes your immune system to recognize them as a threat, triggering an autoimmune flare-up. The reason for this is cross-reactivity, where similar amino acid sequences in different food proteins can cause your immune system to confuse one food for another. This phenomenon is real, and it's something I see often in my practice. Just because a food doesn’t show a reaction on its own doesn’t mean it won’t cause issues when combined with others. The Role of Cross-Reactivity Cross-reactivity happens when your immune system mistakes one protein for another because they share a similar amino acid sequence. For example, if you react to salmon, you might also react to other types of fish due to similarities in their protein structures. This concept is why combining foods like certain grains, dairy, and legumes might trigger reactions in some individuals, even if they’ve tested negative for antibodies to those foods. Let’s look at a real-world example. Imagine eating a gluten-free Kung Pao chicken that’s free of contamination. You’d think that meal would be perfectly fine, right? But if that combination of chicken, spices, and vegetables triggers a reaction, it could be because of how the proteins in those foods interact once combined. Why You Should Pay Attention to Food Combinations In the context of autoimmune disease, where your immune system is already overactive, food reactions can be subtle and unpredictable. So, the next time you’re tempted to dismiss a food intolerance because a test didn’t flag it, think again. It’s not just about the individual foods—it’s about how they interact in your body. You need to pay close attention to how different food combinations make you feel. It’s easy to get caught up in thinking that food sensitivities only apply to the big culprits: gluten, dairy, or soy. But as an autoimmune patient, it’s essential to understand that your body might be reacting to the interaction of multiple foods. So while a test might show that chicken and broccoli are “safe” on their own, eating them together in a casserole could trigger symptoms. The N=1 Approach to Autoimmunity and Food Sensitivities Here’s the bottom line: There is no one-size-fits-all approach when it comes to food and autoimmunity. As I always tell my clients, you are the expert on your own body. Testing can give us a great starting point, but it’s your unique experience that helps us narrow in on what’s truly causing your flare-ups. This is why food sensitivity testing—while helpful—is just one part of the puzzle. You have to be keenly aware of your body’s reactions and the foods you’re combining, even if the individual ingredients test negative for antibodies. Don’t ignore what your body is telling you. If something doesn’t feel right after a meal, listen to it, and make adjustments accordingly. The Takeaway If you're struggling with autoimmune symptoms and haven't been paying attention to food combinations, it’s time to start. While food testing is an invaluable tool, it doesn’t give us the full picture. You may need to do some trial and error with food combinations to uncover what’s really triggering your symptoms. It’s also important to remember that autoimmune healing is complex and individualized. You are an N=1, which means your treatment plan should be tailored to you. Don’t be afraid to advocate for your health, and work with a functional medicine practitioner who can help guide you through the nuances of food reactions and autoimmune management.

For many of us, our experience with food comes with some sort of baggage. Maybe you eat to cope with stress, anxiety or depression. Maybe you’ve grown up with value-words placed on food such as “junk” and “healthy,” and told you couldn’t eat the “good stuff” (brownies and ice cream) until you finished the “yucky stuff” (broccoli and lettuce). Or, even more serious, maybe you or a loved one has struggled or is struggling with an eating disorder. Food is amazing and life-giving. It can be used as a means to celebrate, socialize, or simply just provide fuel for the body. Our relationship with food shouldn’t be a difficult one, it should be an enjoyable one. A way to get to that healthy place in your relationship is to practice mindful eating. Mindfulness is a Buddhist concept of mediation that can help you recognize emotions and physical sensations present. Through mindful eating, you can learn to truly pay attention to your experiences, cravings and physical cues. The basics of mindful eating are: Eat slowly, without distraction. If you are eating with others, take a least five minutes at the start of the meal to enjoy the food on your plate before engaging in discussion. Pay attention to your body--are you still hungry, or are you getting full? Learn to distinguish between cravings and true hunger. Use all your senses when you sit down to a meal. Make an effort to notice how the food looks, smells, tastes, feels in your mouth, and sounds when you chew. Appreciate your food, who has prepared it (even if it’s you--what an accomplishment!), and where it comes from.  Being mindful of your experience will help you slow down while eating. This can prevent overindulgence by making the act of eating intentional instead of automatic. It will also help you become aware of triggers that make you want to eat (are you truly hungry at 9pm every night when you sit down to watch that Netflix show, or do you just pour yourself a bowl of Chex Mix because that’s what you always do?). Knowing your triggers can give you time to process what’s truly going on and the ability to react properly.
