Making vegetables staples in your diet benefits your health — veggies help maintain skeletal health, fight cardiovascular disease and combat cancer. While vegetable juices lack the fiber found in whole vegetables, they contain all of the other beneficial minerals, vitamins and phytochemicals. Vegetable juices especially rich in a few nutrients promote proper brain function.
Juices with Potassium
Vegetables juices high in potassium promote healthy brain function. Potassium allows your brain cells to send nerve impulses composed of short electrical bursts. These impulses transmit information between your brain cells — an essential process for brain function. Potassium also maintains brain function as you age by reducing your risk of stroke, explains the Linus Pauling Institute. Juicing tomatoes and spinach helps boost your potassium intake and contributes to the recommended 4,700 milligrams of potassium you need daily, according to the Institute of Medicine.
Juices with Lycopene
Tomato juice — and vegetable juice blends made with tomato juice — promote brain function by providing lycopene. Lycopene scavenges reactive oxygen species, a type of chemical that damages your DNA, proteins and lipids. Because exposure to reactive oxygen species contributes to neurodegenerative diseases, lycopene might maintain brain function and prevent damage. One study, published in “Neurology” in 2012, found that high levels of lycopene reduced the risk of stroke. Lycopene might also affect gene activity in the brain and regulate appetite, according to an animal study published in “Neuroscience Letters” in 2013.
Juices with Vitamin K
Several vegetable juices, particularly those made with leafy greens, boost your vitamin K intake. Like lycopene, vitamin K helps fight oxidative stress, and protects your brain cells from damage, according to a study published in the “Journal of Medicinal Chemistry” in 2013. A review, from the March 2012 issue of “Advances in Nutrition” notes that vitamin K also activates proteins essential for brain function. Drink broccoli, parsley, watercress, spinach and kale juices as rich sources of vitamin K. They will help you reach your recommended daily intake of 90 micrograms for women and 125 micrograms for men, according to the Institute of Medicine.
Juices with Vitamin C
Vegetable juices provide you with vitamin C, a nutrient that promotes healthy brain function. As an antioxidant, vitamin C protects your brain cells from oxidative stress and also helps you synthesize chemicals that relay signals between your brain cells. An animal study, published in the “Pakistan Journal of Pharmaceutical Science” in 2011, found that vitamin C also prevents brain cell death after a seizure. Drink red pepper, tomato and broccoli juice to help you consume the recommended 90 or 75 milligrams daily for men and women, respectively, according to the Institute of Medicine.
