Georgia-grown berries are full of healthy antioxidants and immune-boosting phytochemicals

By Barbara Worley

Summer means bountiful baskets of blue and red berries in fields and home gardens. Blueberries and strawberries are synonymous with backyard barbecues, vacations and pick-your-own adventures. More importantly, their high level of cancer-fighting antioxidants makes them exceptionally healthy.

Antioxidants counteract the damage caused by free radicals, or molecules created by harmful environmental effects like smoking, sunlight and chemicals that damage healthy tissue cells. Antioxidants come in many different forms, like vitamins and phytochemicals, and are often found in fruits, vegetables and whole-grain products.

Phytochemicals, or substances found in plant foods, and a number of vitamins, such as vitamin C, act as antioxidants in the body. Consuming antioxidant-rich foods decreases free-radical damage and lowers your risk of developing certain types of cancers and heart disease.

There are hundreds of different phytochemicals. Different-colored fruits and vegetables contain different phytochemicals, the pigments that give flowers and foods their unique colors. By eating different-colored fruits and vegetables, you include a wide variety of healthy phytochemicals in your diet. They don’t contribute calories to your diet, but act as antioxidants in the body.

Phytochemicals make strawberries red and blueberries blue. Anthocyanins are found in purple, deep blue and reddish-purple foods, such as blueberries, blackberries, cherries, red grapes, cranberries, bilberries and strawberries.

Some vitamins are also antioxidants. Beta carotene (a form of vitamin A) and vitamins C and E act as antioxidants in the body. Strawberries have more vitamin C than most citrus fruits. Blueberries are also a great source of vitamin C and fiber. 

Originally called “star berries,” the bottom of the blueberry forms a perfect, five-pointed star. Harvest season for blueberries in Georgia runs from mid-April through July, and strawberry season is March through July. July is also National Blueberry Month. Blueberries are one of the few fruits native to North America, and Georgia ranks second in the nation in blueberry production. 

Whether you consume them in a parfait, smoothie or straight from the farm, enjoy blueberries and know that you are eating fresh, local, in-season fruit that improves your health.

Combining data collection and analysis with plant pathology, precision agriculture and robotics, the UGA team will build a photographic library of the foliar symptoms caused by onion diseases and other physiological disorders, feed them into the AI software, and use machine learning to identify the diseases based on pattern and color recognition from the images.

UGA uses AI, robotics to improve Georgia’s Vidalia sweet onion crop 10/23/24 Jordan Powers
A multidisciplinary team of UGA researchers aims to enhance the competitiveness of Vidalia onion growers in Georgia by providing them with the ability to confidently detect onion diseases early, enabling them to make management decisions on their crop at a critical time. These abilities, researchers say, should result in increased yield and quality of marketable onions and an overall increase in efficiency and productivity.

Keep on the grass 08/29/24 Emily Cabrera, Scott Michaux
When the University of Georgia Bulldogs step between the hedges at Sanford Stadium, the grass on Dooley Field needs to look perfect. More importantly, though, it needs to help safeguard the health of athletes who compete on it. Gerald Henry plays a big role in the latter. The UGA Athletic Association’s endowed professor in environmental turfgrass leads a research team in the Department of Crop and Soil Sciences committed to creating sports fields that look good and perform well to limit the occurrence of injuries.

UGArden receives $10K from Kubota, votes can raise to $50K 08/07/24 Isabella Farris
Just a short drive from UGA’s downtown campus sits 10 acres of land known as UGArden. Rows of carrots, okra, kale, squash and much more line the fields. An average of 15,000 pounds of produce is grown on the student farm each year, and that food gets distributed to community members in need. But that capacity and those partnerships could soon grow, thanks to a $10,000 Kubota Hometown Proud Grant, which comes with a valuable additional component: a vote competition that could get UGArden an additional $40,000 and one lucky voter a Kubota mower.

Keep these toxic plants away from your pets 08/06/24 Brenda Jackson
You've heard it all: dog mom, cat dad, plant parent. However you identify, if you are working on your green thumb and have pets, you need to know which of your plants could make your dog or cat sick. Young or new pets tend to nibble and taste plants as they explore and become familiar with their environment, but some garden and house plants are toxic. Symptoms may range from a mild upset stomach to a severe toxic response that can lead to death.
