We are always told to eat our vegetables, but what if some veggies actually aren’t that great for us? Although this is a list of less-healthy veggies, a vegetable from the earth is still a whole food that contains plenty of vitamins and minerals and has unique healing properties — but sometimes there are just healthier options out there.

Here, certified nutritional practitioner and co-founder of Living Kitchen, Tamara Green, shares the surprising veggies you should beware of.

Potato: more starch than vegetable

While white potatoes do have health benefits, many people consider them to be more of a starch and, when compared with their green counterparts, they don't really stand up to the nutritional punch.They're also considered one of the veggies that have the highest pesticide levels, which is harmful for our nervous system and liver, one of the hardest-working organs.These spuds are part of the nightshade family, a group of vegetables that contain alkaloids, which have an impact on nerve-muscle function, joint function and digestive function.

Corn: a genetically modified vegetable

Corn is another staple in people's diet that makes the unhealthy list. It's grilled in summer, popped into bags for movies, processed into a syrup, scooped into salsas and made into breakfast cereals. So, what could go wrong?

According to the Canadian Biotechnology Action Network, more than 80 per cent of the grain corn grown in Canada is genetically modified. GM corn can result in major sensitivities, hormonal changes and changes within the digestive tract.

In fact, it's one of the most common food allergens in North America and is still fed to cows to fatten them up and help create a marbling affect in meat.

Bell peppers: nightshades not good for joint issues

Many North Americans suffer from inflammation in their bodies, which is one of the biggest precursors to heart disease, cancer and diabetes. Although the inflammation that causes these diseases is usually from heavily processed or refined foods, stress and genetics, nightshades — such as bell peppers — may contribute.

Peppers contain the alkaloid and solanine, which can disrupt nerve function and lead to twitching, convulsing and trembling. Bell peppers also pose a problem for joint health.

This vegetable is also not recommended for people with rheumatoid arthritis, osteoarthritis or people with any joint issues.

Eggplant: contains oxalates

Eggplants are also a part of the nightshade family and have some of the highest levels of solanine among all of the nightshade vegetables. For people with chronic inflammation or serious joint problems, it's best to stay clear from these purple veggies.

Eggplant contains oxalates, a naturally occurring substance, that play a role in causing kidney stones. People who have kidney or gallbladder issues or are prone to stones should stay away.

Conventional spinach: high levels of pesticides

Conventional, meaning non-organic, spinach is also on the unhealthiest vegetable list. While spinach is loaded in vitamin A and K and has anti-cancer properties, conventional spinach has one of the highest levels of pesticides. Spinach has more than 48 pesticide residues found on it according to the USDA Pesticide Data Program. That means a big risk of carcinogens, hormone disrupting and neurotoxins.

Spinach also contains oxalates and purines, which can lead to gout and kidney stones. Again, those with kidney problems, it might be best to stay away.

Cherry tomatoes: a part of the nightshade family

Cherry tomatoes are a great snack and the lycopene within tomatoes are known to protect against prostate cancer and osteoporosis. However, they're nightshades that can increase inflammation within the body, especially within your joints. It's a good idea for anyone with arthritis or joint problems to limit their consumption of tomatoes.Tomatoes are also on the Environmental Working Group's Dirty Dozen list.

Celery: notoriously nutrition-less

Many people deem this vegetable to be close to nutrition-less, a simple vessel for dips and not much else. Although this vegetable does pack a fiberous punch and new research has shown its powerful anti-inflammatory and antioxidant properties, celery is currentlyon the Dirty Dozen list.According to the USDA, celery has been found to have a whopping 68 pesticide residues; most of these pesticides being potent hormone disruptors. It's time to jump on the organic celery bandwagon.

Cucumber: may contain synthetic wax

Cucumbers are very refreshing vegetables, yet they also have 35 pesticide residues and, similar to celery, they can be hormone disruptive. The second highest pesticide residues are neurotoxins. Conventional cucumbers can do quite a bit of harm to our bodies considering the pesticide levels.Conventional cucumbers also contain a synthetic wax that is usually made up of chemical contaminants. Opt for organic cucumber to avoid the pesticide residue and to avoid synthetic wax.

Kale: a famous superfood

Kale is one of the most nutritious vegetables out there, it's a local superfood and has many, many healing properties — however, it is on the dirty dozen plus list.

According to Shopper's Guide to Pesticides in Produce, non-organic kale is contaminated with organophosphate insecticides that are highly toxic to the nervous system. Kale is goitrogenic, meaning it can cause or contribute to goiters, but this really only affects people who have an unhealthy thyroid. For people who are healthy, the goitrogenic nature of kale should not be a problem.

Similar to spinach and eggplant, kale contains oxalates and consumption should be slightly monitored if one has an untreated kidney or gallbladder problem.

Squash: Full of minerals… and pesticides

Summer squash is chock full of great minerals, fibre and vitamins; yet, similar to kale, summer squash is contaminated with organophosphate insecticides and according to the USDA, has 41 pesticide residues, most of them being hormone disruptive and toxic to bees.In addition, it's another veggie that's on the oxalates list and can play a role in kidney stones, so those with kidney problems may want to monitor their intake.
