How Does Eating Too Much Sugar Really Affect Your Body?

A new study just came out on about the effect of sugar in our diets and I thought it would be interesting to see a registered dietitians thoughts on this topic. I had Senior Dietitian, Amanda Foti, from Selvera Wellness provide tips and comments on this study.

What’s your stance on the effect of sugar in our diets?

Decreasing sugar intake is not new news. In fact, most American’s at this point understand that this is important for weight management and overall health. However, in the past there have been mostly correlation studies. This study in particular offers insightful information about the direct effect sugar and not an overall lifestyle change may have on our health. It is well understood that consuming high amounts of sugar



whether it’s in one sitting or over the course of a day has negative impacts. Immediate effects include blood glucose spikes, increased insulin production putting more workload on the pancreas, increase fat storage, and energy dips. Long term effects of a high sugar diet have been associated with weight gain, uncontrolled food cravings or addictions, decrease insulin sensitivity, diabetes, non-alcoholic fatty liver and even some cancers. Overall, I agree with the recommendations of reducing added sugar intake to 10% or less of daily calories. However, I think it’s important to focus on all aspects of a healthy lifestyle including improving nutrition, increasing activity, managing stress and sleep habits. All factors have been shown to have an effect on our health.

What do you recommend to your clients as far as sugar consumption goes?

 I recommend that all my clients decrease sugar to be in line with the recommendation of 10% calories coming from added sugar. However, to be successful this must be done slowly over time. It’s important for me to assess what the clients’ current diet habits are and then personalize a plan that will be effective. Dramatically changing eating habits, especially sugar intake, doesn’t happen overnight it takes time.

What are your best tips and tricks for curing ourselves of our sugar addictions?

There has been a lot of research exploring sugar addictions, how they work and how to treat them. Brain scans have relieved that consuming sugar activates a reward sensation, a similar effect that some drugs have. Consuming high volumes of sugar intensifies this sensation overtime until simply seeing or thinking about a sugary snack can cause activation of this reward sensation. This feeling is portrayed to us as food cravings, food cravings that are not linked to any physical hunger cues. The thing with sugar is the more we have the more our brain will crave it. The less sugar we consume the less we will crave it. In my experience, I have found clients successfully overcome food additions or uncontrolled food cravings by slowly weaning off the specified food or food group over time. Having the support of an expert providing accountability and positive reinforcement can help assist this process. First start by having a list of go-to sweet snacks that contain less sugar than what you’re craving. For example, if you’re craving ice cream grab a flavored yogurt instead. Once you’ve mastered that then start to slowly decrease the frequency of giving into these cravings. For example if you have a dessert every night, try to go every other night.

    Sugar is really the main culprit in weight gain and ruining our health. One tip I applied whenever my craving kick in is to drink a bottle of water before giving in to craving. It really helps as often times we confused hunger with thirst. Sometimes after I drink a handful of water my craving stops, giving me the opportunity to reduce my indulgence in sugar.
