Chew on this … the top six
I’m a geek, so as always, let’s begin with a quick chemistry review. Simple sugars, also known as monosaccharaides, are glucose, fructose and galactose. When two monosaccharides get together, they make disaccharides (di= two); these are maltose, sucrose and lactose. To better illustrate this, consider the following: When we eat table sugar (sucrose), our bodies break it down to fructose and glucose. In basic metabolism, anytime we eat and digest a food containing carbohydrates, our bodies break that food back down into monosaccharaides—the most prevalent being glucose. The glucose that is needed by the body is then carried into the cells, with the help of insulin. Any extra glucose floating around in there (sayyy after you go a little too crazy at the pizza buffet) will be stored in the liver or muscles as glycogen, or converted to fat for storage in adipose cells. When our bodies are lacking glucose (during periods of intense exercise or starvation), that glycogen is then re-released back into the bloodstream to be used as energy. Onward.
Foods are made up up macronutrients: carbohydrates, fat and protein. Sugar belongs to the carbohydrate family and contributes 4 calories per gram. Carbohydrates made up of naturally occurring sugars, like fresh fruit, starchy vegetables, whole grains and quality dairy sources are both nutritious and splendid components of a healthy diet when consumed in moderation. These are generally non-offenders if thoughtfully selected to avoid any wacky preservatives or additives. For the sake of this blog post, I will be tackling the dangers of added sugars—these are just like they sound, sugars that are added back into foods through manufacturing. This is done for any number of reasons, one being to enhance flavor. These sneaky added sugars are getting us into a lot of trouble. So how much is too much?
Dietitians, physicians and other medical professionals have really honed in and adjusted our recommendations on sugar over the past 5-10 years. Why, you ask? Well, it seems that sugar may be the culprit to more health issues than once thought, particularly in the form of high fructose corn syrup (HFCS). One study published by the
Insulin resistance occurs when our blood cells become less sensitive to the presence of glucose in the bloodstream, causing cells to utilize glucose less efficiently. It’s kind of like an awful pair of high heels—horrifically uncomfortable at first, but the more you wear them, you kind of get used to the pain, so it becomes your new norm. Thing is, these stupid heels are so bad for your feet. Insulin resistance is kind of the same, and we can thank our highly processed western diet for the increased incidences of this. You see, insulin resistance is a slippery slope and the stepping-stone to the development of serious chronic diseases like heart disease, obesity, metabolic syndrome and type 2 diabetes. It’s no wonder our recommendations have shifted, with an emphasis on limiting the sweet stuff.
Sugar is sneaky. And food manufacturers aren’t necessarily helping when it comes to transparency. Besides adding sweetness to foods, sugar also works as a preservative, texture modifier, fermentation substrate, flavoring and bulking agent. Even more, sugar has about a million different alibis. It is kind of the Jekyll and Hyde of food, if you will. Sugar has many different makeups and names. You’ve got your “plain” sugar (white, refined, high fructose corn syrup), big-word sugars (dextrose, fructose, disaccharides) and natural sugars (honey, molasses, coconut sugar). But let it be known, at the end of the day, no matter if it’s brown, white, crystal, organic or refined … they are all sugar. Yes, natural sugars do offer some benefits (we’ll discuss soon), but our bodies ultimately metabolize them the same, storing excess as fat. Too much of a good thing is still, not good.

So if we’re aiming to consume no more than 5-10% of our calories from added sugars, where can we start? Here’s my list of top recommendations:
- Avoid sugary beverages, including juice. Have you ever made fresh-squeezed orange juice? Think about how many oranges you have to juice to get 6-8 ounces of juice, at least 6-8 oranges. How often do you sit down to eat 6-8 oranges? My guess is probably never because … yuck and hello heartburn. Too much of a good thing isn’t good. Instead, try eating an orange and satisfy that itch for a juice with a fruit infused water.
- Avoid as many pre-packaged and processed foods as possible. Chances are they’re no good and laden with excessive amounts of sugar, salt and other preservatives.
- Plan your groceries ahead and cook at home as much as possible.
- When using or cooking with sugar, try to use natural forms like honey, pure maple syrup or molasses. Not only are these sweeter and more flavorful than your refined sugars (making it easier to not overeat) but you will get bonus points for trace minerals + antioxidants.
- Read labels when you can. “Added sugars,” in grams and as percent Daily Value (%DV), will be included on the label, so it’s really right there at your fingertips. Just remember, the label will reflect a 2,000-calorie diet, so you may need to adjust the %DV based off your personal calorie needs.
- Surround yourself with a positive support group, as this will make it easier to be healthy when eating out or cooking in. Please, do not ditch your friends who drink big gulps on the reg, they’re probably really awesome people. Just try to set a positive example and keep your eyes on the prize.
This journey towards health, happiness and fitness is just that, a journey. Give yourself grace and forgive yourself if you slip up. We’re not all at the same point when it comes to wellness and that’s okay. Heck, I’m no angel. My diet is a mess some days—especially when it comes to sugar. What counts is that you’re trying and taking baby steps towards a healthier lifestyle.
A quick note from Lindsey:
Nice work, Sarah! I thought I might touch a little more on food addiction; It’s a topic that I’ve started covering in one of my classes, so I’ve recently been reading more about it. In college, you and I were taught that certain foods can be addictive and we simply accepted that at face value. However, in my recent research, I’ve learned that there’s a bit of contention as to whether food addiction exists or not.
What does seem to be the case is hyper-palatable or calorie-dense foods, similar to addictive drugs, stimulate dopamine release in our brains. (1.) Dopamine is involved in our brain’s reward and pleasure centers and we are wired to seek out those things that stimulate it. (1.) It probably comes as no surprise that high sugar foods are one of those hyper-palatable foods that spark this response and make us feel all warm and fuzzy after we eat it. This leads us to want to reach for high sugar foods again and again. Many believe this response happens because our genes are adapted to an environment where food was scarce (2.) (think 12,000 plus years ago), so gorging on these foods when they were around, increased our survival. Unfortunately, what that means in modern times is that we are physiologically geared to crave that piece of cake at work for what’s-his-name’s birthday. Whether or not these behaviors qualify as true addiction or addictive-like behavior, we know sugar has a tricky way of finding its way into our bodies. Something that may be helpful is to, first, simply be aware of the potential for high sugar foods to create addictive-like behaviors. Second, I would suggest having a plan for when situations arise that are likely to have tempting foods. This might be keeping a bag of nuts in your purse, bringing a healthy dish to a potluck, or keeping fruit at your desk. Planning ahead may be a big step on our way to kicking our cave-like cake cravings.
Q: Since we are only supposed to allow 5-10% of our daily diet to be composed of added sugars, can we skip sugar/carbohydrates for a few days and then go crazy?
A: The answer is no, but nice try What we’re shooting for here is moderation, which will lead to permanent lifestyle changes. There are no “rollover” minutes when it comes to a healthy, balanced diet. Not only will this lead to burnout and imbalance, worst of all, this will only foster unhealthy relationships with food. Again, we are talking specifically about added sugars. So if you’re trying to keep it under 10% a day, start small; swap your flavored yogurt (usually 10-13 grams added sugar) to plain Greek yogurt sweetened with 1/2 tsp. of honey and fresh fruit (this will net you about 3 grams of added sugar coming ONLY from the honey—we don’t count the sugar in fresh fruit as “added”). Educate yourself but try not to obsess too much about numbers and grams, as this can become exhausting and disheartening. If you want to cut back, I usually advise my patients to retrospectively look back on their diet for three days. Assess about how much added sugar you consumed, then start by making 1-2 small changes. This will eventually lead to big, wonderful changes over time!
Q: I’ve noticed that some people really seem to have a ‘sweet tooth’ while others don’t. For example, my husband couldn’t care less about eating sugary treats while I feel like if I didn’t try to moderate my sugar intake I’d be baking cookies every night. Is there any way to change those cravings? Or is there any science you know of behind why some people may struggle with this more than others?
A: The struggle is real! I, too, have a HUGE sweet tooth. In my experience, it seems you’ve either got your sweet, salty or savory folks; when I’m blue, I reach for chocolate while my co-worker grabs the potato chips. I have a few thoughts on this: It seems there could be a genetic component towards these sweet cravings; one study published in the journal of
All this to say, there are many different theories, but no doubt, change is possible. If you want to make a change, I’m a believer in small, simple adjustments to your everyday routine as opposed to cutting something out cold turkey. Start reading labels and go back to the basics. Some examples are choosing fresh fruit over canned, adding one less spoonful of sugar in your coffee or selecting fresh breads. My absolute favorite bread is Ezekiel sprouted grain loaf (found in the freezer aisle) which has 0 g of sugar. Bread as it should be! Other more “processed” breads will often contain a few grams of sugar, usually coming from high fructose corn syrup.
