Overview

Persimmon, a unique seasonal fruit, also known as sharon fruit, is definitely one to try. With its vibrant orange colour, smooth edible skin and succulent flesh, persimmon is sure to entice your palate with its sweet fruity taste. It is rich in several nutrients, some of which are beneficial for your vision. Read on to find out more about persimmons and learn how they can be of benefit for your eyes.

What is a persimmon?

Persimmons, from the botanical family known as Diospyros, are vibrant and flavorful fruits that come in different varieties, with two common varieties being Fuyu and Hachiya.¹ Originally native to China (which is the top producer worldwide), persimmons are now cultivated in many parts of the world including East Asia, Spain, and even North America, due to their delicious taste and nutritional benefits.¹ They are usually ready for harvest at the start of autumn, in the month of October and a mature tree is able to produce up to 200kg of fruit each year.²

Apart from being a delightful addition to your fruit basket, persimmons offer notable health advantages, particularly for vision. These benefits are attributed to the fruit's rich nutritional content. Persimmons are excellent sources of Vitamin A, a crucial nutrient known for its role in maintaining healthy eyes and preventing vision-related issues.¹

Additionally, their high Vitamin C content contributes to the overall well-being of the eyes by acting as an antioxidant, protecting them from oxidative stress. Including persimmons in your diet may thus contribute to supporting and maintaining good vision.

Types of persimmons (Fuyu, Hachiya)

There are various known varieties of the persimmon fruit and as highlighted previously, the most common types are Fuyu and Hachiya. Other varieties include Mopan, Fuyu Hana (pomelo), Maekawa Jiro, Izu, which are further classified as either astringent or non astringent persimmon.²

The astringent variety needs to be ripe enough before eating otherwise it gives an unpleasant taste in the mouth. An example of this type is the common Hachiya persimmon. On the other hand, non astringent varieties are sweet and can be eaten before they are completely ripe, like the Fuyu variety.²

Nutrients and vision

Persimmon fruit is not only delicious, it is also packed with several nutrients that have a number of health benefits in the human body. This fruit is a source of nutrients such as vitamins (Vitamins C, B6, B12, D & A), minerals (iron, potassium, calcium), dietary fibre and other substances referred to as bioactive compounds (flavonoids, carotenoid & polyphenols).³

Amongst all the nutrients present in the persimmon fruit, some have particular benefits for the human eye. The amount of vitamin A and vitamin C in one whole fruit is approximately 15% and 14% of their respective Recommended Dietary Allowance. Let's explore more about these nutrients and their impact on health.

Vitamin A: Essential for vision, Vitamin A supports the functioning of the retina and is crucial for low-light and colour vision. Its deficiency can lead to night blindness as well as other visual impairments. 

Vitamin C: As a powerful antioxidant, Vitamin C helps protect the eyes from oxidative stress, reducing the risk of age-related macular degeneration (AMD) and other vision disorders.

Fibre: Beyond its digestive benefits, dietary fibre can positively impact eye health. It helps regulate blood sugar levels, reducing the risk of diabetic retinopathy, a condition that can lead to vision loss.⁴

Bioactive compounds: Lutein and Zeaxanthin are Carotenoids that are present in the pulp and skin of the persimmon fruit.¹ They have been found to exhibit antioxidant properties, protecting the retina from degeneration due to oxidative stress. They also help prevent damage to the nerve of the eye (optic nerve), thereby maintaining good vision.³

Ways to enjoy persimmons

The best time to find persimmon in the UK is during the winter months, although they may be seen earlier in the autumn season as well. 

Before we explore ways to enjoy them, it is important to note that the astringent variety of persimmons, such as the common Hachiya, require ripening before they can be enjoyed. To achieve this, allow the fruits to sit at room temperature until they become soft. For the non-astringent variety like Fuyu, they can be enjoyed before they are completely ripe.

Incorporating persimmons into your diet can be both delicious and easy. They can be enjoyed on their own as a snack or used in other kinds of dishes. Here are a few simple recipes as an inspiration:

• Persimmon smoothie: Blend ripe persimmons with yoghurt, a banana, and a splash of your favourite milk for a creamy and nutritious smoothie. Add a touch of honey if more sweetness is desired
• Persimmon salad: Combine sliced persimmons with mixed greens, goat cheese, and a balsamic vinaigrette for a refreshing and flavorful salad. Top with nuts or seeds for added crunch
• Persimmon salsa: Dice persimmons and mix them with tomatoes, onions, cilantro, and lime juice to create a unique and tasty salsa. This can be used as a topping for grilled chicken or fish

FAQs

Are persimmons good for your eyes?

Yes, persimmons are good for your eyes. They are a rich source of Vitamin A, which is a crucial nutrient for maintaining optimal eye health. Vitamin A plays a key role in supporting the function of the retina and contributes to low-light and colour vision.

Including persimmons in your diet can provide your body with this essential vitamin, contributing to the overall well-being of your eyes. Additionally, persimmons contain other beneficial nutrients such as Vitamin C and dietary fibre, further promoting eye health and overall nutritional balance.

What are the side effects of persimmons?

While persimmons are generally safe for most people, excessive consumption or certain conditions may lead to side effects. Here are some considerations:

Oxalates: Persimmons contain oxalates, which can contribute to the formation of kidney stones. Individuals with a history of kidney stones may want to moderate their persimmon intake and consult with a dietician.

Allergies: While rare, some individuals may be allergic to persimmons. Allergic reactions can include itching, swelling, or difficulty breathing. If you suspect an allergy, please seek medical attention immediately.

Digestive sensitivity: The tannins in unripe persimmons may cause digestive discomfort or sensitivity in some individuals. Opting for ripe persimmons and moderating intake can help mitigate this effect.

As with any food, moderation is key. If you have specific health concerns or conditions, it's advisable to consult with a dietitian before making significant changes to your diet.

Is persimmon healthier than apple?

Both fruits offer unique benefits, and the choice between them may depend on individual dietary needs and preferences. Here's a general comparison:

Persimmons are notably high in Vitamin A, which is essential for eye health and immune function. They also provide Vitamin C, an antioxidant important for immune support and skin health. Apples are rich in soluble fibre, specifically pectin, which can help regulate blood sugar levels and support heart health.

Both persimmons and apples have their own nutritional strengths, and including a variety of fruits in your diet is beneficial. The choice may depend on personal taste preferences and specific nutritional goals. 

Is it okay to eat persimmon every day?

Yes, it is generally okay to eat persimmons every day as part of a balanced diet. However, moderation is key. Like many fruits, persimmons contain natural sugars, so it's important to be mindful of your overall sugar intake. If you have specific health concerns or conditions, it's advisable to consult with a dietician to ensure persimmons align with your dietary needs.
