Are Tomatoes High In Nickel?

Nickel is an element naturally present in plants, food, and water, and its content can be increased by human pollution. The majority of people don’t have a problem with consuming foods containing nickel. However, others may have a nickel allergy or sensitivity that reveals itself in the form of rashes or gastrointestinal problems.

As a result, some people may need to limit their intake of foods high in nickel. So, it’s important to know which foods are safe to consume. For example, are tomatoes high in nickel?

Tomatoes are considered to be low in nickel, allowing people with a nickel allergy and sensitivity to consume them. However, their nickel content can differ depending on the way they’ve been grown, prepared, and stored.

So it’s best to ensure you check the content of the specific tomatoes before you’re consuming them.

How much nickel do tomatoes have?

A medium-sized tomato contains, on average, 2-3 μg (micrograms) of nickel in 100g. However, this value can vary from less than 1μg up to 17μg, depending on the soil the tomatoes are grown in, what they are watered with, cooked, etc. On average, though, tomatoes are considered a low-nickel food, so they’re safe to consume by people struggling with a nickel allergy.

Nevertheless, as with any food, even a low amount of nickel might trigger a reaction in susceptible people. As a result, make sure to check how your body’s reacting to eating tomatoes, and if you see any allergic reaction, stop consuming them.

Are tomatoes healthy?

Tomatoes are loaded with nutrients, vitamins, and micronutrients that are essential for good health. For instance, tomatoes can provide you with about 40% of your daily recommended value for vitamin C. This micronutrient is essential in boosting immunity, protecting your skin, and wound healing.

It’s also a water-soluble vitamin, so you should consume it each day to make sure that you have enough of it in your body.

On top of that, tomatoes are rich in antioxidants that help protect your heart and the cardiovascular system. For example, they contain lycopene, which improves the health of your heart muscles, preventing heart attacks and high blood pressure.

Eating tomatoes can also decrease your risk of stroke and diabetes. This is because tomatoes have a low glycemic index which means they don’t cause spikes in your blood sugar levels.

Additionally, tomatoes are a good source of fiber. This carbohydrate helps you feel full and feed the good bacteria residing in your gut. As a result, your metabolism rises, and you’re less likely to overeat. Consuming a diet rich in fiber also soaks up excess stomach acid, preventing acid reflux.

However, consuming too many cooked or canned tomatoes may not be a good idea for people dealing with GERD as they are rather acidic.

Some studies have also indicated that eating tomatoes in all their forms — raw, paste, sauce, soup, salsa, and juice — helps protect you from ovarian, lung, prostate, and stomach cancers. This health benefit is connected to the lycopene, and tomatoes are one of the best sources of this antioxidant.

In addition, it helps to flush out free radicals from your body, stopping the development of many age-related diseases and cell degradation.

Do canned tomatoes have more nickel than fresh tomatoes?

Nickel can leach from containers and cans into the food. As a result, canned tomatoes are way higher in nickel, averaging at around 18μg per can. Moreover, in order to prepare tomatoes for canning, they need to be cooked for a long period of time.

This is often done in a stainless steel pot, which can leach nickel into the tomatoes, further increasing their nickel content.

As a result, people who are particularly sensitive to nickel and those struggling with a nickel allergy shouldn’t consume canned tomatoes, even in small quantities. If they do, they might develop stomach problems, rashes, and painful indigestion. Hence, it’s best to stay clear from them.

Does tomato juice have more nickel than fresh tomatoes?

Tomato juice is higher in nickel than fresh tomatoes; in fact, they contain around 14μg of nickel. This increased value has a lot to do with the preparation method, so if you choose to make tomato juice on your own, you might decrease the amount of nickel.

Store-bought tomato juice can be cooked and stored in metal or steel containers, causing the nickel to leach into the juice. Still, most people won’t have a problem with this, but those with a nickel allergy should stay clear from store-bought tomato juice. If you want to include tomato juice in your diet, you may want to make it yourself at home.

In the same way, tomato marinade and soup have a high nickel content. From the preparation method to storing, nickel can leach into these liquids, increasing the value. However, there are other soups and marinades made from low-nickel foods, such as peppers, that can be used as replacements. Hence, you don’t have to give up your favorite foods completely.

Does tomato sauce have more nickel than tomatoes?

Just as with tomato juice and canned tomatoes, tomato sauce is slightly higher in nickel. Averaging at around 6μg per 60g (a small can). It’s less than tomato juice and canned tomatoes, but for people with a nickel allergy, it might still be too much, causing uncomfortable symptoms. Hence, it’s best if you avoid tomato sauce on a low-nickel diet.

Many people who love sauces choose to replace the tomato sauce with a roasted bell pepper sauce. That way, you can still enjoy your favorite foods with the sauce without increasing your intake of nickel. Plus, roasted bell peppers are incredibly flavorful and low on nickel, so they’re a great substitute for tomato paste.

Most people can safely consume foods containing nickel. However, some experience discomfort after eating such foods, so they may need to avoid them. Fresh tomatoes are low in nickel, making them a good, healthy choice for a low-nickel but balanced diet.

However, tomato paste and juice are a little higher in nickel, so it might be best to avoid them, especially in large quantities.
