Nutrition: Fructose, Immunity and Vitamin D3

Everyone is focused on COVID-19, vaccines and anything that may help or hurt. Well there have been numerous studies showing how critical it is to keep vitamin D3 levels high enough. I’ve shared in my book Natural Tips for Staying Healthy, that getting adequate magnesium and vitamin K2 is important in order to be able to absorb and use vitamin D3 effectively. Well there is something else I have learned about regarding Vitamin D3 levels that actually makes perfect sense to me.

A variety of studies have demonstrated how high sugar intake (and fructose in particular – such as high fructose corn syrup) contributes not only to oxidative stress but to the inactivation of a usable form of vitamin D as well.

This is particularly important since much of the standard American diet is a high sugar, high fructose diet. Packaged, processed (junk and fast) “foods” as well as fruit juices and sodas are loaded with high fructose corn syrup (HFCS). As this study shows, high dietary fructose intake inhibits vitamin D3 levels. You may be getting sensible sun exposure and supplementing with vitamin D3 yet your levels are not improving. Could this be why?

People with diabetes and heart disease are among those who have had the worst outcomes when exposed to this virus. As I say quite often, if we begin with nutrition, it can make a big difference.

The bottom line for me is this: reducing sugar and removing high-fructose corn syrup from your diet is critical.

Could this be why your Vitamin D3 levels are not improving despite all you are doing?

    I can’t say I learned new dietetic info here, I’d heard this before, but you sure have made me pause to consider how well I’ve applied what I’ve heard. Both nutritionally and spiritually my friend. Did have a Covid-related question, and recognize you can’t dispense medical advice. Since the outset of the pandemic, I’ve been supplementing with Vitamin C and D3. As I’m not doing more each day (out of necessity for a while while a loved one heals), I’m adding Super B complex. Is there anything more I can do to boost my immune system? I’ve recently started Humira or psoriatic arthritis, and worry I’m compromising myself more.

      Oh my wonderful friend. I know your focus is your sweet wife and helping her to heal, which is as it should be. I’m so sorry you
      are dealing with psoriatic arthritis on top of it all. Those drugs are not good but sometimes we feel we have no other choice. If you are looking to add another supplement to help protect you, I would continue what you are doing and consider perhaps zinc bisglycinate and quercetin to bolster your immune system. You’re right, I can’t “prescribe” anything – but my role is to help people bolster their immune function through nutrition and strategic supplementations as well as lifelstyle changes like intermittent fasting, etc. I go into detail about all this and more in my book Natural Tips for Staying Healthy. Please always feel free not only to contact me with any questions but also to run anything by your physician so there are no problems with any medications you are on. God bless you my friend.

    Wow! I really wonder what covid would have been like it more people lived a healthy lifestyle. Such great information as always, Ann!

      I’m pretty sure it would’ve been a non-issue although some may have still tried to make is seem worse. Keeping ourselves
      as strong and healthy as possible is always the best way to approach any of the ills that may come down the road.
