For millions of Nigerians, gari is more than food. It is breakfast, lunch, a student’s budget meal and a late-night comfort. Soaked with groundnut and sugar, or turned into eba and eaten with a rich soup, it is hard to imagine our tables without it.
But what does gari mean for your eyes? You may have heard that it “spoils your eyesight,” or that it is perfectly harmless. As with many food stories, the truth sits somewhere in between.
Does Gari Damage Your Eyesight?
Properly prepared gari does not damage your eyes. Gari is made from cassava, and raw cassava naturally contains compounds that release cyanide. The traditional processing steps, which include grating, pressing, fermenting and roasting, are what remove most of it.
The concern is not gari itself. It is poorly processed cassava eaten in large amounts, over a long period. Health researchers have linked long-term cyanide exposure from badly processed cassava to nerve damage, including a condition that can affect the optic nerves and impair vision. This has been seen mainly in communities where cassava is eaten daily without proper detoxification.
What this means for you:
- Buy gari from trusted sources that follow proper fermentation and frying methods
- Avoid gari that smells unusually sour or “raw”, or looks under-processed
- Don’t rely on cassava alone as your main food, day after day
What Gari Does and Does Not Give Your Eyes
Gari is mostly carbohydrate. It gives you quick energy, but on its own it contributes very little of the nutrients your eyes depend on, such as vitamin A, vitamin C, vitamin E, zinc and omega-3 fatty acids.
Plain white gari is not a source of vitamin A. If a diet is built mainly on gari, with little else, the eyes can miss out on important protective nutrients.
Vitamin A deficiency is a well-known cause of poor vision, night blindness and dry eyes, which is why a balanced plate matters.
Yellow Gari: A Better Choice for Vitamin A
Gari that is yellow because it contains red palm oil carries some of the natural vitamin A found in the oil. Researchers are also looking at gari made from biofortified yellow cassava, and at fortified gari, as practical ways to deliver more vitamin A in a food people already love.
Be careful, though. Some yellow gari is simply coloured, and not all of it is rich in vitamin A. The colour is a good clue, not a guarantee.
Making Your Gari Meal Eye-Friendly
You don’t have to give up gari. Build a better plate around it:
- Add leafy green vegetables such as ugu, efo riro or ewedu, which are rich in vitamin A precursors and antioxidants
- Include protein, such as fish, eggs, beans or groundnuts, for zinc and other nutrients the eyes need
- Add colourful vegetables and fruits such as carrots, tomatoes, oranges and pawpaw
- Use red palm oil in moderation where appropriate
- Watch your portions. Gari is calorie-dense, and an oversized serving of eba can crowd out the other foods on your plate
A Special Note for People with Diabetes
Gari has a high glycaemic impact, which means it can raise blood sugar quickly. For people living with diabetes, poorly controlled blood sugar increases the risk of diabetic retinopathy, a leading cause of vision loss. If you have diabetes, speak with your doctor or a dietitian about portion sizes, and make sure you have your eyes examined at least once a year.
Good nutrition supports healthy eyes, but it cannot replace professional eye care. Many eye conditions, including glaucoma and diabetic eye disease, develop silently. A regular eye examination catches problems early, when they are easiest to manage.
Enjoy your gari, balance your plate, and keep your eye appointments.
