146 Reasons to Avoid Sugar


Nancy Appleton, Ph.D. Headshot

By: Nancy Appleton, Ph.D.

Nancy Appleton Ph.D. started writing and lecturing about health in the late 1970s as a reaction to her own poor health. Her discoveries about sugar and other common diet mistakes led to her first book Lick the Sugar Habit, a bestseller, with six more books to follow. Her findings on sugar still hold true today, if not even more so.

Hammer Nutrition's prefatory comments: We are grateful to Dr. Appleton for granting us permission to reprint this most recent version of her eye-opening article. For as long as we have been in business, we at Hammer Nutrition have unwaveringly and zealously advocated minimizing-to-eliminating sugar consumption, both in the diet and during exercise. When you read the following list of science-referenced, health-compromising consequences that are associated with sugar consumption, we are hopeful that it will have a profound impact on you. Remember, what you put in your body determines what you get out of it performance-wise. That's true not only when you're training and racing, but more importantly for everyday living.

About the author (courtesy of www.nancyappleton.com)

Dr. Nancy Appleton has told this story many times, but she is a sugarholic. Years of sneaking sugary snacks only to work it off on the tennis courts led to sickness and allergy as her constant companions. Despite everything the doctors tried she didn't get better, until...

...she asked the question, "What am I doing to make myself sick?"

Thus began an odyssey of research, lecturing and writing in an attempt to bring her discoveries of homeostasis and mineral relationships based on the works of Walter B. Cannon, MD and Melvin Page, DDS to everyone who is sick and needs help. Naturally, this meant that her BS in Health and Nutrition from UCLA wasn't enough of a degree to be believed. This led to a PhD in Health Services from Walden University.

Dr. Appleton has written 5 books: Lick the Sugar Habit, The Curse of Louis Pasteur, Healthy Bones, Lick the Sugar Habit Sugar Counter and Stopping Inflammation. She is also the creator of the Body Monitor Test Kit, an easy at-home tool for testing for homeostasis.

Hello, thank you for your comments and question. The level of scientific evidence and peer reviewed research is overwhelming, but not too popular. You can find a lot of articles, with references in our endurance library and back issues of ENW and Endurance News. Other than when I am eating an apple or a handful of blueberries, I absolutely try to avoid refined sugars. I fall of the wagon from time to time and this is the best place to practice sustainable moderation. Sugary beverages are usually the hidden source of sugar in a lot of people’s diets – fruit juices being #1. Do let us know if we can be of further assistance. BDF

I agree with Beth. BDF is not incorrect on how much a problem sugar is, but I don’t find this article to be constructive or capturing the whole picture. There’s 146 negative reasons and no discussion about when sugar is okay. BDF, you stated safe levels is 1-2 ounces per day but this article does not discuss that and most people think in grams not ounces. You also called sugar toxic, even though it is a naturally occuring part of our diets. The ambiguity and lack of nuance is deceitful, should I not eat a banana every now and then because sugar is toxic and can do 146 bad things? BDF I hope this clarifies the point Beth was making because I feel like you talked past it.

Hi Jan, Thank you for your comment and adding to the conversation, whether attempting to clarify another readers comments or not. That being said, it seems to me that it may be some readers are reading more into this article than was there. It did not say, nor have I ever advocated zero intake of all types of sugar. Dr. Appletons’s list and what we are talking about are “added”, highly refined, processed sugars – not bananas. Dr Appleton is the author of Suicide by Sugar and Lick the Sugar Habit – both excellent and comprehensively documented – I encourage everyone add these to their library. These refined sugars, led by high fructose corn syrup in even small amounts are toxic, it’s a fact with mountains of data to prove it. It also appears that this article is being considered in a vacuum or standing alone, as opposed to the recent articles on keto’ish diets and intermittent fasting – hopefully you’ve read all of those and their comments as well. I’m really not sure what to make about your comment regarding ounces and grams – In the USA, SAE is still the national units of measure and I live in the USA, but go back and forth with units of measure depending on what country I am in or communicating. There are 28.32 grams per ounce. I merely converted, and rounded the 50 grams per day maximum daily intake of “added”, “refined” sugars. Brian David Frank.

here are 28.32 grams per ounce

I would love to see a list like this of all/most of the names that manufacturers use to hide the different sugars used today. Whether real/natural or lab manufactured.

Hi Eric, Thank you for your comment and suggestion. We’ll get to work on that list! BDF

Eric Schroeder

Great list and many I didn’t know. I cut out sugar about 4 years ago due to a nasty yeast infection of a rare type that was difficult to eradicate (I had to use an experimental pharmaceutical compound to treat it) and I still don’t know if I’m clear of it. Nice side effects: my eczema went away and I dropped 6 pounds. It was the reason I found your products, as I was looking for a sugar free electrolyte drink mix and found Fizz. Discovering all your products are sugar free made me so happy.
