Yes, Purple Tomatoes Are Safe to Eat
For many, the sight of a dark purple or black tomato can be unfamiliar and raise questions about its edibility. However, purple tomatoes are not only safe to eat but also offer several health advantages. The deep color comes from anthocyanins, a class of antioxidants also present in fruits like blueberries and blackberries. There are two primary types of purple tomatoes available on the market today: heirloom varieties and bioengineered varieties.
Heirloom purple tomatoes, such as the 'Cherokee Purple' or 'Black Krim', have been cultivated for generations through conventional breeding. These varieties are the result of natural genetic mutations and selective propagation. Bioengineered (or GMO) purple tomatoes, like 'The Purple Tomato' from Norfolk Healthy Produce, have been specifically modified to increase their anthocyanin content significantly. Both types have been deemed safe for consumption by regulatory bodies, including the USDA and FDA in the United States, confirming they pose no greater health risk than conventional tomatoes.
The Health Benefits of Anthocyanins
Anthocyanins are powerful plant compounds with notable health-promoting properties. Their benefits include:
- Antioxidant Effects: Anthocyanins neutralize free radicals in the body, which helps reduce oxidative stress and damage to cells, a process linked to aging and many chronic diseases.
- Anti-inflammatory Properties: Research indicates that anthocyanins can help reduce inflammation, which is a key factor in conditions like heart disease, cancer, and age-related decline.
- Cardiovascular Health: Regular consumption of anthocyanin-rich foods is linked to a lower risk of cardiovascular disease.
- Other Potential Benefits: Studies suggest they may also offer anti-cancerous, anti-microbial, and neuroprotective effects, potentially helping with conditions such as obesity and chronic diseases.
Purple Tomatoes vs. Red Tomatoes: A Nutritional Showdown
While all tomatoes are a healthy addition to your diet, purple tomatoes offer a unique nutritional edge due to their high anthocyanin content. Here's how they compare:
| Feature | Purple Tomatoes (e.g., Norfolk Healthy Produce) | Red Tomatoes (Conventional) | 
|---|---|---|
| Key Antioxidants | High in anthocyanins, plus lycopene and carotenoids | High in lycopene and carotenoids | 
| Color Source | Anthocyanin pigments (from snapdragon genes or natural breeding) | Lycopene pigment | 
| Flavor Profile | Often rich, smoky, earthy, and savory, with lower acidity | Classic tomato flavor, often more acidic | 
| Cooking Suitability | Best raw in salads and fresh dishes to preserve color | Excellent for cooking, sauces, and canning | 
| Shelf Life | Bioengineered varieties often have an extended shelf life | Standard shelf life varies by type and freshness | 
The Diverse World of Purple Tomato Varieties
Beyond a single type, a wide array of purple tomatoes exists, each with its own characteristics. Some popular varieties include:
- Cherokee Purple: A famous heirloom beefsteak tomato with a dusky rose-purple skin and a rich, smoky flavor. Its flesh is dense and juicy, making it perfect for slicing.

How to Enjoy Purple Tomatoes in Your Kitchen
