Why are Purple Vegetables Good for You?
Purple vegetable have many health benefits, thanks to their high content of anthocyanins and other phytochemicals. Here are some of the reasons why you should include purple vegetable in your diet:
- They protect your cells from oxidative stress and damage. Oxidative stress is caused by free radicals, which are unstable molecules that can harm your DNA, proteins, and lipids. Free radicals are generated by various factors, such as pollution, smoking, alcohol, UV rays, inflammation, and aging. Antioxidants like anthocyanins can neutralize free radicals and prevent them from causing harm.
- They reduce inflammation and chronic diseases. Inflammation is a natural response of your immune system to fight infections and injuries. However, chronic inflammation can lead to various diseases, such as diabetes, cardiovascular disease, cancer, arthritis, and Alzheimer’s disease. Anthocyanins can modulate the production of inflammatory molecules and enzymes, such as cytokines, prostaglandins, and COX-2.
- They improve your blood circulation and lower your blood pressure. Anthocyanins can relax and dilate your blood vessels, which improves your blood flow and reduces your blood pressure. This can lower your risk of heart attack, stroke, and other cardiovascular problems. Anthocyanins can also prevent the oxidation of LDL cholesterol (the bad cholesterol), which can cause plaque buildup in your arteries.
- They enhance your brain function and memory. Anthocyanins can cross the blood-brain barrier and reach your brain cells. There, they can protect your neurons from oxidative stress and inflammation. They can also modulate the activity of neurotransmitters, such as dopamine and serotonin, which affect your mood, cognition, and behavior. Anthocyanins can also improve your learning and memory by stimulating the growth of new brain cells and synapses.
- They support your eye health and vision. Anthocyanins can protect your eyes from oxidative stress and inflammation caused by UV rays, blue light, or diabetes. They can also improve your night vision by regenerating a pigment called rhodopsin in your retina. Rhodopsin is responsible for converting light into electrical signals that are sent to your brain.
