Study finds paprika improves visual processing speed, reaction time
In a study published December 4, 2014 in the Archives of Biochemistry and Biophysics, researchers from the University of Georgia reveal new scientific evidence demonstrating that the speed at which we process information and react correlates with daily intake of Zeaxanthin, a nutrient commonly found in paprika. Top college and professional sports organizations see research as an opportunity to combat the growing stimulant trend in college and professional sports.
In a study published in the Archives of Biochemistry and Biophysics, researchers from the University of Georgia reveal new scientific evidence demonstrating that the speed at which we process information and react correlates with daily intake of Zeaxanthin, a nutrient commonly found in paprika. Top college and professional sports organizations see research as an opportunity to combat the growing stimulant trend in college and professional sports.
The research published in the Archives of Biochemistry and Biophysics reveal that consuming 20 mg of dietary zeaxanthin daily, a nutrient commonly found in bright colored fruits and vegetables, speeds up visual processing speed, or the speed at which our eyes and brain communicate, by 20% after four months.
The research, which was conducted by the University of Georgia’s Visual Sciences Laboratory, is unique because it is the first double blind, placebo controlled study to demonstrate significant improvements in reaction time in young, healthy individuals, using dietary zeaxanthin as a nutritional approach.
Dr. Billy Hammond, the study author and lead researcher at UGA Vision Sciences Laboratory, sees implications beyond just sports. “Processing speed is central to many aspects of life – from reading, to reaction time when driving to successful sports performance. The ability to actually change brain function in relatively young, healthy adults based on nutritional intake has wide implications for our ability to optimize human performance.”
Dave Ellis, a sports dietitian with over 30 years of experience in the field, sees meaningful implications for the future of sports nutrition. “A common solution to improving reaction time for young athletes is excessive caffeine consumption,” according to Ellis. “Young athletes are vulnerable to transition from caffeine to a cocktail of stimulants that show up illegally in dietary supplements in the form of active pharmaceutical ingredients.”
While stimulant use in sports continues to grow, sports dietitians and medical personnel responsible for the health and well-being of college and professional athletes continue to search for alternatives.

Get smart about your heart
From regular checkups and reducing stress to eating well – including heart-healthy snacks like grapes – and exercising regularly, these simple steps can help boost your heart health.
A crucial component of overall well-being, heart health can be a barometer for living a long, healthy and happy life. Because heart disease is the leading cause of death in the US, according to the Centers for Disease Control and Prevention, taking steps to reduce your controllable risk factors – including poor diet, stress and inactivity – can set you on the right path.
From regular checkups and reducing stress to eating well – including heart-healthy snacks like grapes – and exercising regularly, these simple steps can help boost your heart health.
Know Your Numbers
Knowing key health metrics such as blood pressure, cholesterol levels, blood sugar levels and body mass index can help you and your health care provider identify potential risks early. Schedule annual checkups and discuss any concerns you may have about your heart health. Early detection and risk factor management can reduce the likelihood of developing heart disease.
Eat More Fruits and Vegetables
Incorporating a variety of colorful fruits and vegetables into your diet can ensure you get a broad range of vitamins, minerals, fiber and antioxidants, all of which contribute to a healthy cardiovascular system. For example, leafy greens like spinach and kale are high in potassium, which helps manage blood pressure. Fresh grapes contain 7% of the daily recommended intake of potassium, are a good source of vitamin K and are also a natural source of beneficial antioxidants and other polyphenols, including flavonoids, that can help relax blood vessels and promote healthy circulation. Some studies also suggest grapes have a beneficial impact on blood lipids and more.
In fact, one study found women who consumed 1 1/4 cups of grapes every day benefited from reduced blood triglyceride levels, LDL cholesterol levels, inflammatory proteins and other markers of heart disease.
Bright, juicy and bursting with flavor, Grapes from California can be enjoyed by the handful or blended with rich bananas, tangy Greek yogurt and a hint of almond in The Great Grape-Acai Smoothie Bowl for a delicious blend of fruity flavors at breakfast, lunch or snack time – it not only tastes great, but supports a healthy heart.
Get Moving
Regular physical activity is one of the most effective ways to improve heart health. Exercise strengthens the heart muscle, improves blood circulation and helps maintain a healthy weight. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, as recommended by the American Heart Association, such as walking, jogging or swimming with strength training exercises like lifting weights or using resistance bands mixed in to help reduce the risk of heart disease and improve overall cardiovascular health.
Manage Stress
Consider your stress level: chronic stress can negatively impact heart health, increasing blood pressure and other risk factors for heart disease. Techniques such as deep breathing, meditation, yoga and regular physical activity can help manage stress levels and maintain a healthy heart. Additionally, taking time to engage in hobbies, spending time with loved ones and ensuring adequate sleep are stress-reducing activities that improve overall well-being and heart health.

Eat your greens and skip the sugar spikes
Cruciferous vegetables like broccoli and kale could help with the management of blood sugar levels, particularly for people at risk of type 2 diabetes and cardiovascular disease (CVD).
New research by Edith Cowan University (ECU) has found evidence that cruciferous vegetables like broccoli and kale could help with the management of blood sugar levels, particularly for people at risk of type 2 diabetes and cardiovascular disease (CVD).
PhD student Ms Emma Connolly investigated whether cruciferous vegetable intake improved glycaemic control (blood sugar control) compared to root and squash vegetables in non-diabetic adults with elevated blood pressure.
In a randomised, controlled, crossover trial, participants consumed four serves per day of either cruciferous vegetables (broccoli, cabbage, cauliflower, kale) or root and squash vegetables (carrot, potato, pumpkin, sweet potato) with lunch and dinner meals for two weeks.
“Our participants wore glucose monitors throughout the study, so that we were able to measure blood sugar levels continuously throughout each two-week period,” Ms Connolly said.
“We found that, when participants consumed the cruciferous vegetables, they had less variable blood sugar levels compared to when they consumed the root and squash vegetables. We also noted that these participants had a smaller spike in sugar levels after the meals. A central goal of blood sugar control, particularly for people with diabetes, is to smooth out spikes and reduce variability in blood sugar levels throughout the day. Stable blood sugar, with minimal peaks and less fluctuations is associated with better overall health and wellbeing.”
Ms Connolly said further research is essential to fully understand the underlying mechanisms driving these findings, as well as to explore the broader clinical implications.
“Continued investigation will be crucial to determine how these vegetables can be effectively incorporated into dietary recommendations for improved blood sugar regulation and overall health management,” she said.
Poor glycaemic control is estimated to occur in 541 million individuals worldwide. Ms Connolly noted that dysregulated glucose control increases the risk of type 2 diabetes and subsequent CVD and has a substantial societal impact.
The total cost attributed to type 2 diabetes with CVD is projected to exceed AUD$18.7 billion in Australia alone by 2031.
“Less than 1 in 15 Australian adults meet vegetable intake recommendations. Even more concerning is that cruciferous vegetables are among the least consumed vegetables. Adding vegetables like broccoli, kale, bok choy, gai lan, and cabbage to your meals most days could make a big difference to your health,” Dr Lauren Blekkenhorst said.
