Simple carbohydrates are basic sugars that provide quick energy. They are found in foods like fruits, milk, and sweeteners such as sugar and honey. These carbohydrates are easily digested and absorbed by the body, leading to a rapid increase in blood sugar levels. While simple carbohydrates can be beneficial when consumed in moderation, excessive intake, especially from processed sources like candies and soft drinks, can lead to health issues such as weight gain and diabetes. It's important to balance simple carbohydrates with more complex carbohydrates, which provide longer-lasting energy.
