Please put a cap or limit on how many grams of sugar that goes into our food. There is no need for 45g of sugar in anything. Not sure anything should exceed10g-15g of sugar in any serving size and that may be too much. Sugar should be limited in our food.

Excessive sugar consumption has become a major public health concern, with numerous studies indicating that it contributes to a variety of metabolic, cardiovascular, and mental health issues. While sugar itself is not inherently harmful in moderate amounts, excessive intake—especially of added sugars—can lead to long-term health complications. Below, are some of the key effects of high sugar consumption on the body, based on findings from scientific research.
- Obesity and Weight Gain
A large body of research links excessive sugar consumption to obesity. One of the primary reasons is that sugar-rich foods and beverages, such as sugary drinks and processed snacks, are calorie-dense but nutrient-poor. Studies show that consuming liquid sugar (e.g., sodas, fruit juices, and sweetened teas) does not trigger the same feeling of fullness as solid food, which can lead to overeating and weight gain (Malik et al., 2013). Moreover, fructose (a form of sugar commonly found in high-fructose corn syrup) is metabolized in the liver, where it can promote fat storage, particularly visceral fat, which is linked to metabolic diseases.
Study Example:

- Type 2 Diabetes
The relationship between excessive sugar intake and the development of Type 2 diabetes is well-established. High sugar intake leads to elevated blood glucose levels, which, over time, can cause insulin resistance, a hallmark of Type 2 diabetes. High-fructose consumption, in particular, has been shown to impair insulin sensitivity and disrupt the body’s ability to regulate blood sugar. As insulin resistance worsens, the risk of developing Type 2 diabetes increases.
Study Example:
Stanhope, K. L., et al. (2009). “Consumption of fructose and high-fructose corn syrup in beverages increases visceral adiposity and lipids and decreases insulin sensitivity in overweight/obese men and women.” The Journal of Clinical Investigation, 119(5), 1322-1334. Link to study
- Cardiovascular Disease
Excess sugar intake has also been linked to an increased risk of cardiovascular diseases, including coronary artery disease and hypertension. Consuming too much sugar can elevate triglyceride levels, increase blood pressure, and promote inflammation—all of which are risk factors for heart disease. The American Heart Association recommends limiting added sugars to no more than 6% of daily caloric intake to reduce cardiovascular risk.

- Tooth Decay and Oral Health
The link between sugar and tooth decay is well-documented. When sugar is consumed, bacteria in the mouth ferment it, producing acid that erodes tooth enamel. This leads to cavities and other dental issues. Frequent consumption of sugary foods and drinks, particularly in between meals, provides a constant supply of sugar to harmful bacteria in the mouth, increasing the risk of tooth decay.

- Mental Health and Cognitive Function
Emerging evidence suggests that excessive sugar consumption may negatively impact mental health, contributing to mood disorders like depression and anxiety. High sugar intake is thought to cause fluctuations in blood sugar levels, leading to energy crashes and mood swings. Additionally, chronic consumption of sugar can lead to inflammation in the brain, which has been linked to depression. Some studies also suggest that a high-sugar diet may impair memory and cognitive function.

- Addiction-like Effects
There is growing evidence to suggest that sugar can have addiction-like properties. Research has shown that sugar activates the brain’s reward system by triggering the release of dopamine, the neurotransmitter associated with pleasure and reward. This can lead to cravings and overeating. While not exactly the same as substance addiction, some researchers argue that the compulsive consumption of sugary foods could share similar neurobiological pathways to addiction.
Study Example:
Avena, N. M., Rada, P., & Hoebel, B. G. (2008). “Sugar and fat bingeing have notable differences in addictive-like behavior.” Journal of Nutrition, 138(5), 849-852. Link to study
Conclusion
The consumption of excessive sugar, particularly in the form of sugary beverages and processed foods, has been consistently linked to a variety of negative health outcomes, including obesity, Type 2 diabetes, cardiovascular disease, tooth decay, and mental health issues. Emerging research also suggests that sugar can act on the brain in ways similar to addictive substances, contributing to unhealthy eating behaviors. Reducing the intake of added sugars and focusing on a balanced diet with whole foods can help mitigate these risks.
As we continue to understand the long-term effects of sugar on health, it is clear that public health recommendations must emphasize the importance of limiting sugar consumption to promote overall well-being.
