With fall just over a month away, apple picking season is almost here as well.
But exactly how healthy are apples? And is one type or color of apple more nutritious than another?
Two nutritionists helped get to the bottom of these nutritional questions, while also addressing whether an apple a day really does keep the doctor away.
“In terms of color, apples can range from green (like granny smith) to yellow (like golden delicious), to red (like empire and gala), and often a mixture of colors (like honeycrisp),” Kelley Springer of the New York Apple Association told Fox News Digital via email.
Springer is a registered dietitian and certified dietitian.
Apples come in many varieties and colors, but “when it comes to nutrition, the difference between apple varieties is generally minimal,” she said.
“However, apples with redder or purple skins, such as the delicious red apple, often have higher levels of antioxidants compared to those with lighter-colored skins,” Springer said.
Although the nutritional content can “vary a bit” depending on the type of apple and the environment it’s grown in, Springer said that “in general, apples are an excellent source of dietary fiber, vitamins and antioxidants.”
There is actually some truth behind the saying “an apple a day keeps the doctor away,” Diane Lindsay-Adler of Boston Children’s Health Doctors told Fox News Digital via email.
“Apples can help protect against serious diseases, including heart disease, diabetes, cancer and more,” said Lindsay-Adler, a registered dietitian.
Red apples, she said, are that color because they contain something called anthocyanins, which are “powerful antioxidants.”
They “help reduce inflammation in the body,” she said.
Green apples get their color from chlorophyll, another antioxidant, she said.
Chlorophyll “is being studied and may have protective effects against cancerous tumors.”
And finally, yellow apples have carotenoids, Lindsay-Adler said.
These “reduce the risk of some cancers and eye diseases.”
While there isn’t much dramatic variation in apples in regards to their color, different varieties of apples can address different nutritional needs.
Green apples are “lower in sugar and high in fiber,” Lindsay-Adler said, meaning they’re “a good choice for those watching their sugar intake.”
Meanwhile, fresh apples are “known for their high water content” and overall balanced nutrient profile, she said.
They are a “hydrating and nourishing option,” added Lindsay-Adler.
But regardless of the type of apple one chooses to eat, there are “a plethora of specific health benefits,” Springer said.
“The flavonoids and antioxidants in apples are beneficial for maintaining healthy blood sugar,” she said.
One study found that “women who ate one or more apples a day had a 28% lower risk of type 2 diabetes compared to those who ate none,” she said.
Apples are also great for gut and heart health, Springer said.
“The pectin in apples is a prebiotic, providing food for friendly gut bacteria,” she said.
“Pectin can contribute to the use of gut bacteria for growth, which is good food for your microbiota.”
The nutritional content of apples also helps keep blood pressure at healthy levels, Springer said.
Plus, “potassium helps relax blood vessels, which can reduce the risk of cardiovascular complications associated with high blood pressure.”
