What Colour apple is the healthiest?

Apples come in a wide variety of colors, ranging from the familiar red and green to more unique shades like yellow, pink and purple. But does the color actually make a difference when it comes to health benefits? Let’s take a look at what the research says about the nutritional content of different colored apples.

Red Apples

The quintessential red apple is likely the first kind that comes to mind. Red apples get their vibrant color from antioxidants called flavonoids, particularly anthocyanin, which gives red apples their ruby hue. Studies have linked anthocyanins to a variety of health benefits:

  • Lower risk of heart disease
  • Anti-inflammatory effects
  • Cancer prevention
  • Better brain health

In addition to anthocyanins, red apples contain other polyphenol antioxidants like quercetin, catechin, phloridzin and chlorogenic acid. These compounds provide antioxidant, anti-allergy and anti-cancer benefits.

Some popular varieties of red apples include Red Delicious, Fuji, Gala, Jonathan, McIntosh and Honeycrisp.

Green Apples

Green apples get their color primarily from chlorophyll rather than anthocyanins. Some of the most antioxidant-rich green varieties include Granny Smith, Jazz, Honeycrisp and Pippin apples. Here are some of the key nutrients found in green apples:

  • Quercetin – A flavonoid that may help reduce inflammation and lower risk of cancer and heart disease.
  • Vitamin C – Green apples are an excellent source of immune-boosting vitamin C.
  • Fiber – The crisp texture of green apples lends to their high fiber content.
  • Vitamin K – Important for bone health and wound healing.

While green apples have different phytonutrient content compared to red varieties, they still provide a significant amount of polyphenol antioxidants.

Yellow Apples

Yellow apples are lower in anthocyanins than red varieties, accounting for their brighter, golden color. Some of the most common yellow apple types are Golden Delicious, Jonagold and Mutsu. Here’s what you’ll find in yellow apples:

  • Vitamin C – Like green apples, yellow apples are high in immune-strengthening vitamin C.
  • Beta-Carotene – Yellow pigments called carotenoids like beta-carotene are found in yellow fruits and vegetables. Beta-carotene functions as an antioxidant and is converted to vitamin A in the body.
  • Phenolic Acids – Yellow apples contain high amounts of phenolic acids like chlorogenic acid and caffeic acid, which have antibacterial and anti-inflammatory activities.

So while yellow apples may have different phytochemicals than their red and green counterparts, they still supply beneficial plant compounds.

Mixed Color Apples

Many apple varieties feature a mix of hues like red, yellow, green and golden. Examples include Pink Lady, Jazz, Piñata and RubyFrost apples. The blended color results in a diverse spectrum of polyphenols.

For instance, Piñata apples are predominantly yellow with red striping. This cross of colors provides flavonoids from both the red anthocyanins and yellow carotenoids. Basically, mixed color apples offer a wider range of antioxidants and phytonutrients.

Purple and Blue Apples

It’s rare to find apples in shades of purple or blue, but some specialty farmers are growing unique colored varieties. The pigments providing the lavender, indigo and violet hues are anthocyanins, the same antioxidants that give red apples their classic color.

Some blue and purple apple varieties include:

  • Purple Pinot
  • Azure Blue
  • Pazazz
  • Cosmic Crisp

These unique apples provide the same anthocyanin antioxidants as red apples. Early research suggests the blue anthocyanins may have enhanced health effects compared to red pigments.

Comparing the Antioxidant Content by Color

Several studies have attempted to tally and compare the total antioxidant contents across colored apple varieties. The findings show that while different colors provide varying phytochemicals, all apples are health-promoting fruits:

  • A 2012 study measured polyphenol content across several apple strains, reporting the highest antioxidants in red-fleshed apples and lowest in yellow varieties. But all types showed beneficial activity.
  • A 2005 analysis also found antioxidant activity was higher in red apples compared to green and yellow. However, yellow Golden Delicious apples still had high total phenolics.
  • Research in 2004 compared Red Delicious, Golden Delicious, Granny Smith and Fuji apples. The red and green apples had the highest flavonoids, with Yellow Delicious apples containing the most carotenoids.

So while red apples appear to lead in certain studies, ultimately all apples provide significant phytochemicals and antioxidant content. The subtle differences in nutritional profiles are less important than eating apples regularly as part of a healthy diet.

Phytochemical Content of Apples by Color

This table summarizes the key phytochemicals provided by different colored apples:

Apple Color Phytochemicals
Red Anthocyanins like cyanidin and quercetin
Green Chlorophyll, vitamin C, quercetin
Yellow Beta-carotene, vitamin C, chlorogenic acid
Mixed Diverse spectrum of phytochemicals
Purple/Blue Anthocyanins like cyanidin

Health Benefits of Apples

Given their stellar nutrient and phytochemical content, it’s no surprise apples have been linked to a host of health benefits:

  • Heart health – Studies show apples reduce cholesterol, lower inflammation and improve artery function to protect your cardiovascular system.
  • Cancer prevention – The antioxidant and anti-inflammatory compounds in apples may help deter cancer cell growth.
  • Brain health – Rat studies found apple extracts enhanced neurotransmitter function and reduced Alzheimer’s disease markers.
  • Blood sugar control – The fiber and polyphenols in apples help slow digestion and regulate blood glucose levels.
  • Gut health – The polyphenols act as prebiotics to nourish beneficial gut bacteria.
  • Lung function – Evidence links apple intake with reduced asthma symptoms and improved lung function.

While most of the research has focused on Red Delicious apples, these benefits likely extend across all varieties, regardless of color.

Which Color Apple is Healthiest?

Based on the nutritional profiles and health research, it appears all apples offer antioxidant, anti-inflammatory and disease-fighting properties. While subtle variances exist between colors in phytochemical content, there is no clear winner when determining the single healthiest apple color.

For the most well-rounded nutritional intake, eating a mix of red, green and yellow apples is recommended. The varying phytochemicals and nutrients complement each other to provide the widest range of health benefits. Additionally, don’t be afraid to try unique colored apples like purple or blue when you find them.

At the end of the day, the healthiest apple is the one you eat regularly as part of an overall healthy and balanced diet. Focus on incorporating whole, fresh apples of any color into your daily routine. Enjoy them as snacks, in salads, baked into desserts or sliced onto whole grain oatmeal or yogurt. Your body will thank you.

The Bottom Line

Research shows apples provide a number of important nutrients and antioxidants that offer significant health benefits. While different colored apples contain varying phytochemicals, there is no conclusive evidence showing one color is healthier than the rest.

For the best results, eat a variety of apples in an array of colors. And remember, a fresh apple a day really does help keep the doctor away regardless of whether it’s red, green, yellow or something in between!
