What impact can excess sugar in the diet have on health?

Excess sugar in the diet can lead to weight gain and contribute to "sugar crashes." When an individual consumes high amounts of sugar, particularly from refined sources like candies, sodas, and desserts, it causes rapid spikes in blood glucose levels. This spike can lead to a temporary boost in energy; however, it is often followed by a sharp decline in blood sugar levels, commonly referred to as a "sugar crash." This crash results in feelings of fatigue, irritability, and increased hunger, potentially leading to the consumption of more sugar to regain energy, thus creating a cycle of overconsumption.

Additionally, consuming excess sugar over time is linked to various health issues, including obesity, type 2 diabetes, and heart disease. By understanding the negative consequences of excessive sugar intake, individuals can make informed dietary choices that support better overall health.
