How does sugar affect the immune system? A devastating path to sickness and death

Eating sugar will soon become known as a degenerative lifestyle, which contributes to ill health and disease. It will be considered similar to the smoking lifestyle because sugar changes the human body so drastically and so slowly that it’s not even considered a poison to the layperson. What sugar brings upon us and what it does to our immune systems is criminal.

Let’s say YES to a healthy vibrant lifestyle and NO to a disease filled, drug addictive future.

We all know sugar leads to tooth decay but did you know that it does much more harm? There seems to be a never ending battle with the unhealthy GMOs (genetically modified organisms) white and brown sugars, high fructose corn syrup, cane sugar, and many more sugars that are constantly being thrown in our faces by TV networks, corporate marketing and sugary offices parties.

I don’t know about you but it’s a BIG problem. Sugar is so cadaverous on the body, most people are clueless as to its side effects.

I am going to discuss how eating processed sugar is giving your body a death sentence.

After reading this article my hope is that you reconsider sugar as an addiction. Once started it’s very difficult to stop. I especially hope that you may start reading food labels or start cooking healthier foods at home.

My wish for you is to make an action plan for living without mainstream processed sugar sources and start maintaining better eating habits for yourself, your family, your friends and for generations to come after you. In this blog article I’m going to talk about how does sugar affect the immune system?

How does sugar affect the immune system?

There are three major components of how sugar affects the immune system: 1. Low immunity cell count, 2. Turning off genetic gene expression and 3. Weaker immunity by malnutrition.

1. With every bite of sugar, vitamins and mineral nutrients are being depleted. These nutrients are very important to live and are needed daily to function to become more healthy.

This is happening because sugar increases glucose in the blood and therefore tissues can’t regenerate fast enough causing low white blood cells counts to drop.

This is important because white blood cells help fight infection and are major players in immunity defense.

Monica Reinagel, MS, LD/N, CNS on the blog Quick and dirty tips Says that when eating sugar the affects on the immune system last many hours and the immune system is at a disadvantage because it’s not as strong.

When this happens she says neutrophils which are white blood cells can’t protect us like normal because they can’t gobble up or eat the invader coming into our body as quickly.

They function best by eating up the bad guys (foreign bacteria, fungi and viruses). She references a study done on this in the 1970s that proves this.

2. Scientific research has learned that eating foods will either turn “on” or turn “off” genetic gene expression according to Dr. Mercola’s blog on: Your Genes Remember A Sugar Hit. Sugar is directly responsible for putting our genes to sleep making them inactive.

Studies done on sugar have shown that sugar actually promotes ill health with specific genes that are designed to help protect us against diseases like heart disease, cancer and diabetes.

This is important because if genes are turned off by sugar consumption then the protective measures of our genes can’t help our immune system fight diseases effectively.

It’s like throwing away our internal shield that is there to protect our bodies in tandem with our immune system; by turning them off like a light switch.

We need our genes to be turned on to the power of healing defense and to be working, awake and active in their duties. They shouldn’t be asleep.

This shouldn’t be happening because we need our genes to process certain functions in our body so that we can live healthy without diseases.

These proper functions include protein synthesis which if we didn’t have then we wouldn’t be able to break down food well when we eat it.

The impact is profound because foods that have nutritional value have genetic information and this information is giving instructions to our immune system and our genes so that they can help in immunity defense.

Our body understands it and knows what to do with that kind of nutritional information of which sugar doesn’t have.

If our genes get no information to help them stay normal, stay “on” and functional by being actively on point then it’s like they’re not needed when they are so desperately needed to help out our immune system’s functions.

Sugar is showing the body it must be dormant, non responsive. The only way to reverse this is to stop eating sugar.

Isn’t it amazing that what we eat is what we become?

What we are today and how we are today is because of great nutritional foods passed down from generations before you, giving you stronger immunity.

Or your family genetic line is not so fortunate and the kiss of death with sugar which is changing our genes and how they express themselves has created sickness for generations.

Knowing this, if you eat nutrient dense healthy foods you are telling your cells of your body and your genes to turn on the internal superpowers to help your immune system response to be normal. Wouldn’t you want more immunity support?

It’s like an internal superpower. While eating sugar is telling your body to drop your shield defenses and allow enemies into your body, your genetic cells become compromised and dysfunctional, contributing to cancer and tumors. This is huge!

If your immune system response is already malfunctioning and you have lower immunity than eating the wrong diet can cause sickness faster and death to quicken.

Dr. Mercola talks about this in his article on sugar and gene expression. (See above link.) He talks about how a substance in broccoli called isothiocyanate activates the genes in our DNA to help ward off cancer. Isn’t that fantastic?

I don’t know about you, but I’d rather eat foods that fight for my survival, not diminish it.

What if sugar wasn’t in our diets like it is so presently today?

We’d have so many healthy vibrant people on this planet and our lifestyle values would be very different from the contrary of running into a fast food restaurant or drive through to get our quick sugar fix. Of course, we’re not in that ideal, healthy perfect world.

Avoiding sugar will definitely keep inflammation away and will keep the body from having to deal with the physical stress that it brings to our immune system and body.

It’s truly fascinating that we really are what we eat, especially when talking about foods that affects our gene expression.

3. Sugar depletes nutrients and doesn’t allow the body to absorb nutrients adequately as nature intended leaving the body malnourished and starving. In this way sugar is affecting your immune system by literally causing malnutrition by not giving the body what it needs, nutrients.

This is so extreme that it weakens the immune system and it cannot rely on the nutritional foundation one would normally get from eating healthy foods to do its job to protect your body from harmful diseases and infection.

Then to top it off we eat carbohydrate foods with it and this prevents absorption even more because sugar is too aggressive and is very overpowering.

When eating sugar with a carbohydrate such as breads and foods such as donuts or crispy creams it becomes more hostile.

Another thing happens when there’s too much sugar in the body our Vitamin C absorption is decreased.

So even if you take extra vitamin C to help your body, sugar prevents its absorption automatically.

At Health Freedom Resources their blog talks about his and how our cells need vitamin C to function and when eating sugar it’s dumbing down our cells or making them go into a comatose like state.

How does sugar affect the immune system?

Well, according to Natural Health 365 when sugar is consumed it increases the glucose levels in the body and this prevents Vitamin C from being able to get into the cells adequately enough to do its job to enhance cellular functions and this results in a weaker immune system.

Cellular tissues of the body are thus unable to regenerate in magnitudes as it normally would, proliferating to help the immune system function properly. Our cells require vitamin C to function, so this is a very big deal! He even states in his blog that Vitamin C deficiency is a big reason many people get heart disease. That’s fascinating!

Anyway, lack of nutrients in the blood stream from eating sugar is why overeating occurs because the cells of the body are still hungry. Yes, our cells eat just like that video game of Pacman.

The excessive glucose is stored as fat because the liver can’t store anymore of it so it puts it in our freezer (fatty tissues) for extra energy if needed for later.

This is why there’s concern for women getting breast cancer because the excess toxins and glucose get stored in fatty tissues.

The excessive amounts of glucose contributes to not just weight gain by storing fat on the body, it contributes to heart disease, diabetes, infections, inflammation and cancer.

Sugar is food for cancer cells allowing them to replicate faster and thrive in the body better. Cancer cells eat up the sugar and become stronger to allow multiplication to occur, increasing cancer cells throughout the body.

The vital nutrients needed for our bodies can’t be absorbed well effectively when sugar is present and therefore Vitamin C, magnesium, Vitamin D, calcium and chromium get depleted.

Sugar literally takes over and goes to the front of the line because not only does it have more glucose to feed the brain, it’s invasive in what it does in the body by pushing out the real need for our body: nutrients.

Sugar does this through an increase in enzymatic activity to synthesize Vitamin D an C faster not letting it be absorbed in our tissues leaving our immunity to be weaker than it was before.

This then allows us to become more susceptible to colds and flu. Low levels of Vitamin D and C equals lower immunity responses.

This is why diets don’t work. It’s because when eating sugar and food’s devoid of nutrients, genes are turning off their superpowers and they can no longer do their job to help us stay healthy and therefore we keep eating trying to fill the void of the nutrients we are lacking and in the end there’s no satiation.

in conclusion, sugary foods and sodas provide no nutritional value. They are providers of death to the cells of our bodies because they give empty celeries and tricks our digestive system, brains and immune system that it’s being fed when it isn’t.

Sugar is a lie, a lie our bodies really want to believe because it tastes so darn delicious!

Sugar gives nothing in return except for addiction and disease. High fructose corn syrup and or cane sugar are mostly made of GMOs (genetically modified organisms) but even organic cane sugar has the same effect.

It’s important to know what we are eating and how our dinner is being made.

Sugar, its like a fraudster in our body telling the brain it feels good all the while it wreaks havoc on our immune system functions.

It doesn’t allow us to absorb calcium, vitamins D and C, and magnesium along with other vitamins and minerals when consumed because it’s blocking our ability to absorb nutrients, syntheses them and thus it turns off gene expression.

This prevents our immune system response to be defensive and have a foundation of protective measures to take place inside us.

To reiterate: sugar studies have shown that when eating sugar, it actually promotes ill health by turning off specific genes that are designed to be turned on to help protect ourselves against heart disease, cancer and other diseases.

This is something so astounding to me that it truly makes me see how amazing our bodies are and how much we want to survive.

If you know that you have inflammation and pain then stay away from sugar. I know from personal experience that sugar can and it will irritate nerves and elevate the pain already there.

Chronic pain is nothing to mess with. The idea that white blood cells diminish when sugar is present tells me that sugar interrupts our normal immune functions.

If this is happening then it’s also a domino effect and then our immune system can’t identify hormones correctly when sugar is added to the mix because sugar is so invasive in what it does.

As Dr Mercola states in his article it turns off the immune system’s ability to identify or interpret hormone metabolism which means that the body can’t handle sugar very well and is unable to determine whether or not we are full making the hunger hormone increase which in turn causes the obesity epidemic.

According to the immune system plays a big roll in hormone production by making hormones, storing hormones and discharges hormones.

Since surgery foods are so powerful at disrupting normal body functions it’s advisable to eliminate it from the every day diet.

Do it and your body will thank you for it. You’ll be healthier and your immune system will be stronger for it.

May we all truly reevaluate this intense need for a sugar fix so that we can be healthy happy and vibrant in our lives.

  1. Hi this is a very comprehensive post. I always knew that too much sugar was bad for you and that it falls within that group of anything white should be cut back on. Sugar primarily feeds cancer but it also contribute to a lot problems within our body. I always wondered why we get a sugar craving. All good reading, I also checked out your post on healthy babies and natural delivery which was really interesting and filled those gaps I had in this area and germs around kids, a bit worrying now though with our current climate, but immune systems have to be strengthened so exposure is for sure the way to go. All your posts are quite thorough and informative and look forward to the next read.

    • Hi Julia,
      Yes, sugar is the body’s demise. It’s unfortunate because it tastes amazing. Thank you so much for your kind comments. I am truly enjoying the research on my topics and it’s so fascinating how our bodies work and function. I’m glad I can share in the knowledge. To abundant health! 😊

  2. In depth and detailed article about the dangers of excessive sugar! I knew sugar was bad for us but I am somewhat surprised at the amount of damage it can cause!
    This will help me to look at the ingredients in packaged foods!
    Is natural sugars in fruits okay for the body or can that be harmful as well?

    • Hi Justin,
      Right! I had no idea until I started researching this topic how much information I would be gathering. I’m so astounded by the amount of information that I found online. Honestly, it was so overwhelming that I had to cut down the article by 2000 words. So, this is half of what I ended up with which was at 4000. This article is specifically talking about processed sugars. I truly believe that natural sugar from foods like fruits, vegetables and natural sugar like honey and stevia are good sugary foods because they’re not altered or adulterated in any way. Get them natural and raw. They have vitamins, minerals and nutritional information our body can breakdown and utilize. We can’t do that with regular processed sugars. However, some health doctors and health practitioners believe otherwise because it’s about excessive fructose that is in very high amounts that can be dangerous. I definitely feel better eating the whole fruit while say juicing an apple has a higher sugar content. Getting the natural fiber with the fruit is best. Experiment with your body and see how it goes. It does take two weeks or up to 14 days to detox from sugar and I will be talking about that in my next blog. Great question! Thank you for such nice comments. To your abundant health! 😊✨

  3. Hey Lili, Thanks for this great article. It is really scary to see what sugar does to you.
    I have one question actually. Do you know any natural foods which can counter the effect of sugar?
    I am not a sweet stuff fan but do eat a little almost everyday.

    • Hi Rajith,
      Yes I do! That’s a great question. I will be talking about this in my next blog. If you eat bitter foods it reduces the sugar cravings by slowing down sugar absorption. We absorb sugar very fast and thus eating bitter foods will help control blood sugar. Thanks! 🤠❤️

  4. Hi,

    Thanks very much for an article that highlights a Public Health problem that millions of people are not aware of, and that governments don’t seem to wish to tackle decisively.
    Sugar is dangerous and harms the world’s economy.
    Sadly, it’s so easy to adjust when one start cutting down on sugar intake – just days and one gets used to the new “dose”! So, everyone can slowly cut down until they are taking zero or near-zero sugar!

    Thanks very much for sharing.

    • Hello Teboho,
      Thank you for your comment. It is such a big problem. It’s bigger than we all realize. Children start eating processed sugar at such a young age. It doesn’t seem to end. It’s very sad what sugar does short term and long term to our bodies. 😊

  5. Agree with everything you said. We should not introduce sweets to our child at a very young age. Isn’t sugar more addictive than cocaine?

  6. What a nice post you wrote Lili! I really enjoyed reading it and could not be silent about your post so I decided to leave my comment here and say Thank You for sharing this quality post. Actually I was looking for information about the effects of sugar on immune system and when I landed on your website and read this post, it answered all my questions in details and it was exactly what I wanted to know.
    I’m happy that you’ve decided to write about this topic and share it with others. It’s very useful post in my opinion and can definitely be used as a great source for everyone who is interested to know about this topic.

    I will definitely come back to your site again to read more posts. Keep up quality articles! 🙂


    • Ali,
      Thank you! 🙏🏻 I truly appreciate your feedback. I’ve been thinking about sugar for a long time now and about how badly it makes me feel. All I have to do now is think about how it makes my immune system weaker and I avoid it like a plague! What it does to our immune system is just like what Kryptonite does to Superman. It’s Kryptonite for the immune system! lol 😆 Anyway, thanks for your pure encouraging words. Blessings for amazing health. 😊💫

  7. You did a great job Lili! I believe that this is the information that can’t be find on the web easily and you decided to share it with others for free, that’s really great!
    I didn’t know much about affect of sugar on immune system but I’ve been always interested to know more about this and your in-deep post helped me a lot. I don’t know if you wrote this post 100% by yourself or got help from other sources as well, anyway, it has really brilliant information which convinced me to share it with my friends on social networks.
    I think, the Internet needs more quality posts like yours these days, especially when we see a lot of crappy ads and scams about this topic. You can’t read a post easily on a website without seeing tons popups but your site and post is an ideal example of a quality article which is not covered by annoying ads, has very useful information and lets readers enjoy reading every piece of it.

    Thank you again and I wish you continue providing such that quality information in the future which turn the Internet and blogs into a better place to surf!


    • Hi Ali,
      Thank you for such thoughtful words. I appreciate your comments. I too couldn’t agree with you more about all those ads that clutter the blog posts. They get in the way of what I want to read. It’s one of my many pet peeves in this world. Ha-ha! Thanks for noticing! I am the original writer for all my blogs. It does take time to write but I highly enjoy it. Have a fabulous day. 😊💫
