FRUCTOSE

Fructose, a type of sugar, can have several effects on the body, including liver damage, increased triglycerides, and potential contributions to metabolic disorders like obesity and type 2 diabetes. Excess fructose consumption can lead to the conversion of fructose into fat in the liver, contributing to non-alcoholic fatty liver disease. Additionally, high fructose intake has been linked to insulin resistance and increased cardiovascular risk. The liver metabolizes fructose, and excessive intake can lead to an overload, resulting in fat accumulation and potential liver damage, including non-alcoholic fatty liver disease (NAFLD) hepatic fat. Increased Triglycerides: Fructose can increase the production of triglycerides, a type of fat, in the blood, which can contribute to the growth of plaque in arteries and increase the risk of heart disease. Insulin Resistance: High fructose intake has been associated with insulin resistance, a condition where the body doesn't respond properly to insulin, a key hormone for regulating blood sugar, and a precursor to type 2 diabetes. Obesity and Weight Gain: While not directly proven to cause weight gain, high fructose intake, especially when combined with a high-calorie diet, can contribute to weight gain and increased body fat. Metabolic Syndrome: Fructose consumption has been linked to an increased risk of metabolic syndrome, a cluster of conditions including high blood pressure, high blood sugar, abnormal cholesterol levels, and excess abdominal fat, all of which increase the risk of heart disease, stroke, and type 2 diabetes.  Other Potential Effects: Gout: Some studies have linked high fructose intake to an increased risk of gout, a painful form of arthritis. Kidney Stones: High fructose intake has also been associated with a higher risk of kidney stones. Digestive Issues: In some individuals, fructose can cause digestive issues like bloating, gas, and diarrhea due to fructose intolerance. Hereditary Fructose Intolerance: A rare genetic condition called hereditary fructose intolerance can cause severe health problems when fructose is consumed, including liver and kidney damage, hypoglycemia, and even organ failure. Natural vs. Added Fructose: The fructose found naturally in fruits and vegetables in moderate amounts is generally not a cause for concern. However, excessive consumption of added fructose, particularly from sources like high-fructose corn syrup and sugar-sweetened beverages, can have negative health consequences. Yes, fructose, a type of sugar found naturally in fruits and also added to many processed foods, can contribute to blurry vision. This is because high blood sugar levels, including those caused by fructose consumption, can lead to swelling of the lens in the eye, affecting its ability to focus properly, resulting in temporary blurry vision.
