Tomato helps meet our daily needs of vitamin C, as it contains 13.7 mg of vitamin C per 100g. Tomato juice and tomato paste also contain decent amounts of vitamin C. Ketchup isn’t a good dietary source, though.
How much vitamin C in a tomato?
Tomato is a good dietary source of vitamin C. It contains 13.7 mg of vitamin C per 100g, which is 15% of the Daily Value. A whole tomato provides up to 28% of the recommended daily intake:
- small tomato (2-2/5″) contains 12.5 mg of vitamin C, or 14% DV.
- medium tomato (2-3/5″) contains 17 mg of vitamin C, or 19% DV.
- large tomato (3″) contains 25 mg of vitamin C, or 28% DV.
- a cup of chopped tomatoes contains 24.7 mg of vitamin C, or 27% DV.
As fresh tomato and other tomato products are favorite foods with decent amounts of vitamin C, they’re key dietary sources of vitamin C for many people.
The amount of vitamin C in tomato depends on the ripening stage. Most tomato varieties have more vitamin C when they are ripe. Green tomatoes have less vitamin C.
What’s the vitamin C content of tomato juice?
Tomato juice and even canned tomato paste are also rich in vitamin C:
- tomato juice contains 70 mg of vitamin C per 100 mL. This amount is about 77% of the DV.
- tomato paste contains about 22 mg of vitamin C per 100g.
Tomato paste has a lower vitamin C content than tomato juice because vitamin C is pretty vulnerable to heat. After all, tomato paste is highly processed food.
However, tomato paste is good for you, as it has an extremely high lycopene and beta-carotene content. It contains 28,800 mcg of lycopene and 900 mcg of beta-carotene per 100g.
Vitamin C in ketchup
Ketchup is also highly processed food. Most vitamin C is destroyed during the processing method. Ketchup has negligible amounts of vitamin C. It contains only 4 mg of vitamin C per 100g.
But, ketchup is high in lycopene. It contains 12,062 mcg of lycopene per 100g. Lycopene isn’t vulnerable to heat and other processing methods. Actually, ketchup is the main lycopene source for many people.
Can we get enough vitamin C from diet?
The recommended daily intake of vitamin C is 90 mg for adult men and 75 mg for adult women.
We can easily get more than enough vitamin C by following a plant-based diet. Plants are the main dietary sources of vitamin C. Most healthy people don’t need high dosages of vitamin C from supplements.
