Rethinking Our Relationship with Sugar: The Science and Why Moderation is Key


*Please note that this blog is not for people with diabetes, epilepsy, or other conditions where carbohydrates play a critical role.


Sugar, without a doubt, is one of the most demonized and debatable ingredients in the world. I am at my wit's end with the constant inundation of "sugar detox" plans on magazine covers and the persistent advice from so-called "experts" who base their opinions on personal health benefits they have experienced after reducing their own sugar intake. It's becoming exhausting, and I'm starting to feel like a straight jacket might be necessary to keep me sane.


Just a quick side note: if you personally feel better without any sugar in your diet, that's totally fine! However, I urge you to please refrain from telling others that all forms of sugar - whether naturally occurring or added - are unequivocally terrible for their health. It's just not accurate or fair to make such a blanket statement.


It may seem like a basic concept, but it's worth noting that all carbohydrates - 100% of them - are ultimately broken down during digestion into simple sugars like glucose, fructose, and galactose. That sweet potato you enjoyed for dinner? It breaks down into glucose. The carrots and tomatoes in your salad? Also glucose through digestion. Whether you're munching on low-carb wraps, apple slices or a hearty serving of pasta, all of them will eventually be converted into glucose - which is the simplest type of sugar molecule.


Now here is why that is important:

Glucose is an absolutely essential metabolic fuel for the brain's optimal functioning. Brain activities such as thinking, learning, and memory are intricately connected to glucose levels in the body and how effectively the brain can utilize this vital energy source. It's important to note that unlike other organs and muscles, the brain cannot store glucose. Additionally, brain cells require twice the amount of energy as the cells in the rest of our body.


Now, if we turn our attention to those who follow a low-carb diet or are generally cautious of "sugar-laden" foods like pasta (ha!), what's happening in their brains? Well, this is where things get interesting (prepare to nerd out!). As we've established, the brain needs glucose as its primary source of energy. However, when carbohydrate intake is limited, the body has a pretty ingenious trick up its sleeve: a process called gluconeogenesis (pronounced glu-co-neo-gen-e-sis). Essentially, this process enables the body to create glucose from non-carbohydrate sources, such as lipids and amino acids - ultimately providing sufficient fuel for the brain to function effectively.


It's worth noting that many individuals who follow a low-carb diet often experience headaches and brain fog as they initiate this new nutrition plan. This is typically due to their brain cells yearning for glucose - the essential energy source we've been discussing. It's like the brain's way of saying "hey, I need some glucose over here!"


It's important to remember that removing all carbohydrates from your diet, including the healthy ones, can eliminate a significant source of essential nutrients these foods provide. For instance, fruits like bananas, apples, figs, pineapple, and mango - often viewed as high-carb foods - are rich in potassium, vitamins A and C, and fiber, which can help alleviate inflammation and promote regularity. Whole-grain pasta and bread are also excellent sources of fiber, iron, magnesium, and zinc - and have higher protein content than their more processed white counterparts.


Ultimately, it's all about finding a balance - extremes are rarely the answer. Consuming a diet that prioritizes nutrient-dense foods will make you feel fuller and more satisfied. It's worth noting that when nutritionists talk about "limiting sugar," we usually refer to highly processed sugary treats like candies and cakes.


It's important to remember that pasta you had for dinner, the sweet potato you had at lunch, and that breakfast tortilla - while not necessarily containing added sugar - ultimately break down into glucose, which is once again THE primary fuel source for both your brain and body to perform at their best. So for the love of all things holy, stop vilifying the simple glucose molecule!
