Why do I keep getting sick? Part 1

The winter time is unlike any time throughout the year.  We have extra stressors around us all the time including the holidays which include shopping, changes in weather including less sunlight, and increased consumption of sugar and processed foods from all the desserts and holiday goodies.

I am going to try to keep things simple so after reading this post you’ll have some excellent action items (AI) you can then use to apply to your health and for those interested some additional information on your immune system so you can understand how things work better.

Your immune system has two branches, you can think of it like a seesaw, as one goes up one goes down.  Understanding the basics will help you understand how these changes are affecting your body.    If this is too much info, just skip down to the action items for the meat and potatoes.

Immune system:  To keep things simple, you have two sides of your immune, TH1 & TH2

TH1:  This side is provides the front-line military defense for bacteria, virus and other pathogens trying to gain access to our bodies.

TH2:  This side is primarily responsible for making antibodies (soldiers that are specific to whatever is making us sick) to the various bacteria, virus and pathogens that have already invaded our body.  In other words, this provides the back-up defense for our body when we have already been compromised.  Vaccines work on this branch, more on this on a separate post!

It usually takes about 1 week for our TH2 side to get ramped up or i.e.  It takes about 1 week for the back-up soldiers to get called into action to help us out.  That’s why the average cold lasts about 1 week.   In summary the Th1 side is the wall that prevent things from coming in and TH2 side are the backup soldiers there to help in-case the bad guy break through the wall

Alright so after learning a little bit more about your immune system, the suggestions I am making below should now make a little more sense to you.  I am going to break up my recommendations into two categories, diet & lifestyle, and supplementation.  The first post will be on diet and lifestyle!

Diet & Lifestyle:  Actions Items

1.  Sleep:  Sleep is the primary time where your immune system recharges.  Our bodies are naturally on a light and dark cycle, so the prime time to tap into natural repair is right around 10pm.  At this time our body is making human growth hormone (which helps repair our body) and is going through a process known as cellular autophagy which is repairing our immune system.  Sleep deprivation is considered by the WHO as the only non-substance carcinogen in the same league as cigarettes and asbestos.  AI:  Sleep before 10pm and make sure it’s  in a dark environment.

2.  Vitamin D:  With less sunlight our body has less ability to make vitamin-d on our own.  So if you live in a warmer climate in the winter time get some healthy sun exposure without burning.  For the rest it will be a necessity to rely on a vitamin D3 supplement, stay tuned to the supplement post coming later!

3.  Avoid sugar:  According to John Briffa MD and Paul Chek 1 tsp. of sugar will inhibit your immune system for up to 4 hours.  So do yourself a favor and avoid sugar, which includes grains, starches alcohol and wine.  in the end all of these items are broken down by your body into sugar.  PS:  There are 10 tsp’s of sugar in 1 can of coke which can potentially decrease your immune function for almost 2 days!   Diet coke is not a good alternative either.   AI:  Healthy organic meats and vegetables especially cooked in a crock pot can be really helpful, chicken soup (minus the noodles), grandmas everywhere would be so proud!

4.  Listen to your body:  Your body will tell you when it’s starting to get sick.   Your energy will start to decline; you may start to feel a slight twinge in the back of your throat as well.  “If you can listen to your bodies’ whispers, you won’t have to endure its cries…”

This isn’t a time to be tough and power through it.  Your immune system takes a lot of energy when it ramps up the TH1 side to  fight an infection.  Instead of fighting your immune system, try a more gentle approach like a lite yoga session, a walk, or even take an off day and try to get some extra rest.

5.  Sauna session:  Your body will naturally try to increase its body temperature to increase the effectiveness of the TH1 side of the immune system .  This is why a fever can be a very beneficial thing, as long as the fever isn’t going >105 F there really is no need to worry. AI: You can mimic this state naturally with a sauna session which can help get your immune system ready to go!

6.  Hydration:  I recommend increasing your water consumption during these sick times.  ½ your body weight in ounces is a good baseline, so even a little more can helpful.  Teas can be good to, just avoid the ones with caffeine.  AI: Drink up “The solution to pollution is dilution!”

7.  Manage stress:  Stress comes in many shapes and sizes, emotional, physical, and chemical.  The above suggestions already address the chemical and physical but the emotional is not something we have dealt with yet.   Research has shown that after a fight with a spouse your immune system can be weakened for up to 2 days (1).   AI:  Avoid unnecessary stress-full conflict with your signifcant other when feeling under the weather.

8.  Wash your hands:  This is the main vehical in which viruses and other bad guys are transferred.  Washing your hands throughout the day can decrease the spread of these pathogens.

9.  Introduce fermented foods into your diet.  A real easy way to do this is start consuming sauerkraut or kimchi from your local health food store.  The fermentation processes, the way in which these foods are prepared produce beneficial bacteria (pro-biotics) which have an important role in your gut health.  70% of your immune cells are located in you gut (MALT & GALT), the healthier your gut, tthe healthier you immune system.  Anti-biotics can destroy the beneficial bacteria that we get from probiotics and fermeneted food, that’s why anti-biotics should be a last resort.

Important point, antibiotics do not  make your immune system stronger they just kill the bad guys that are making you sick.  All of the suggestions mentioned in this blog post will increase your immune function thus helping your immune system to kill off all of these bad bugs on your own.  A little help from supplements can’t hurt either!   More on pro-biotics in part 2!

New study says red meat is linked to cancer and heart disease? Fact or fiction???

According to a new Harvard study, red meat is linked to cancer and cardiovascualar disease.  Every day we see studies saying one thing and then saying the other things a few months later.  After a while the public doesn’t know what to believe…  Why is this?  I will break down the research and show you why this study isn’t all it’s cracked up to be, and what to look for to know if a study holds true merit.

Here are some simple items that need to be looked at first.  Once observed it is easy view the short coming of this study linking meat to cancer and cardiovascular disease.

1. This study is an observational study.  In the study they gave questionnaires to individuals every 4 years and looked back to see who got cancer and heart disease and what they were eating. The problem with this type of study is there can be other confounding variables like… The person ate processed hot dogs as well as the gluten/sugar rich bun.  Or the person ate sausage and meatballs… on top of a pizza that was loaded with gluten/sugar. I think you are seeing a pattern, that when a lot of processed meats are eaten usually there is a bunch of sugar going down with it.

The variable of gluten/sugar combined with the meats are whats called a confounding variable, it is an important factor in the study that could be causing the factors in question “heart disease and or cancer”.
We need to do specific studies that actually isolate the meat from the bun/sugar to to control for these confounding variables.

2. To actually prove cause and effect we need to conduct a clinical trial.  A clinical trial is where you isolate different groups where you can control for the diet and also have a placebo group to compare.  An epidemiological study  (like this one) can only conclude correlation…  correlation and causation are two different things.   Gray hair is correlated with aging…  it doesn’t mean gray hair causes you to age…   Just an association…  I think you get the picture.

The study I am referring to may look like this:

group 1:  Fed organic pastue fed meats with no process sugar or grains allowed.

group 2: Fed conventional meet.

group 3: Fed conventional meat with grains and sugar.

group 4: Placebo control group, ate what ever they wanted.

Going one step further we can make the study blinded or double blinded where the patients don’t know what group they are in (very difficult), and the scientist don’t know what each patient is eating (easier).  This then controls for any pre-existing bias the scientist and or patients might have.

These people would then live in a metabolic ward for lets say a few months or so where they were actually fed the foods in questions.  As you can see studies like this are incredibly expensive there fore they aren’t done.  So we use less expensive epidemiological studies using surveys and then we extrapolate the information to the public like it’s a matter of truth.

Epidemiological studies like this one only help you to produce a hypothesis i.e. “I think meat causes cancer and cardiovascular disease.” From there we can now conduct a double blind placebo controlled study to test this hypothesis. It’s irresponsible to extrapolate that information and put it in the media and scare everyone (which is done here) before the clinical trial has been completed.

3. These studies never control for the quality of meat as mentioned above. Organic pasture fed vs free change vs anti-biotic vs hormone free vs conventional factory farmed etc.  It controls for processed vs non processed, but you can still eat bacon (which is considered processed) and it could be bacon from organic pasture fed sources of pork. The quality of the animal meat matters, but research conveniently ignores this.

Personally I do believe that conventional meat is bad for you and causes the issues sited above. But not because of the meat in general; but because of the quality of the meat and the hormones, antibiotics and the poor quality of food the animals were fed before it ended up on your table.  In other words, animals that are treated well and fed well have the potential to provide wellness to the person that consumes them.  Animals that are treat badly, fed like crap and injected with drugs don’t have the ability to convey health to the person that consumes them.

I hope the information presented in this article will help you sniff out studies that aren’t quite what they’re cracked up to be
