Is Zucchini Bad For You?



Short answer

Technically a fruit, but used as a vegetable, zucchini is a great way to bolster health. It is imperative that you buy organic, though, as non-organic varieties are known for having high levels of pesticide residue.



Letter Grade for Zucchini


Overall beneficial to your health. Things rated a ‘B’ may have some harmful qualities to pay attention to.

View Full Grading System

Category ‘A’


Very healthy and numerous health benefits. Side effects are rare. Things rated an ‘A+’ are typically necessary for survival (for example, water).


Very healthy and numerous health benefits. A few harmful qualities may be associated, but only under certain circumstances such as an allergic reaction.


Very healthy and numerous health benefits. Harmful qualities may be associated, but aren’t usually serious.

It is important to note that even the best things in life can become bad in immoderate amounts. So, although something may be rated an ‘A+’, overconsumption/overdoing can bring unwanted effects.

Category ‘B’


Very beneficial to your health. Things rated a ‘B+’ may have a few harmful qualities to pay attention to.


Overall beneficial to your health. Things rated a ‘B’ may have some harmful qualities to pay attention to.


More beneficial to your health than not. However, harmful qualities are most likely associated and shouldn’t be overlooked.

The main difference between category ‘A’ and category ‘B’ is the harmful qualities typically present in ‘B’ items. Serious side effects are usually uncommon, but are still possible and should be taken note of.

Category ‘C’


Both beneficial and harmful qualities associated. Things rated a ‘C+’ are typically a bit more on the beneficial side. Still, moderation is important.


A fairly even ratio of beneficial and harmful qualities. Moderation is important. Very general topics that can lean towards both sides of the spectrum will be placed here as well. Rice, for example, can be good or bad depending on the type.


More harmful than beneficial. Side effects are common, especially when consumed/done excessively. Moderation is very important.

Category ‘C’ usually denotes to both good and bad qualities. When it comes to this category, it is important to keep this word in mind: moderation.

Category ‘D’


Harmful to your health. Although benefits may be associated, the bad most likely outweighs the good. Moderation is very important.


Harmful to your health. A few benefits may be associated, but the bad outweighs the good. Moderation is extremely important.


Harmful to your health. Very few, if any, benefits are present. Things in this category should be avoided as much as possible.

Category ‘D’ is typically for things that are more harmful than beneficial. While consuming/doing something unhealthy once in a blue moon shouldn’t hurt, we definitely recommend eliminating ‘D’ items as a regular part of your routine/diet.

Category ‘F’


Category ‘F’ is for things that fail to bring anything beneficial to the table, and are very harmful to your health. We recommend completely avoiding anything in this category. Long-term side effects of ‘F’ items are usually very serious.

Category ‘N’


‘N’ stands for neutral. Things placed into this category are generally (a) neither good nor bad for you, or (b) lack the necessary evidence to reach any conclusions.


Long answer

While we may think of zucchini as a vegetable it is, like tomatoes, technically a fruit. Whether you want to call it a fruit or vegetable, the fact is eating a zucchini can benefit your health in a variety of ways. First, let’s take the water content. Zucchini is about 95% water. This is more than a watermelon (which is about 92% water) and just under that of lettuce (around 96% water). Water it is important in muscle flexion, transporting oxygen to the cells, and a host of other biological functions. Not only is eating zucchini a good way to rehydrate, it also provides natural sugars and electrolytes such as potassium that are lost during a workout.

Zucchini also contains a high amount of antioxidants, chemicals that fight damage caused by free radicals. Of these antioxidants, zucchini contains over 40% of the daily goal for lutein and zeaxanthin, carotenoids that help promote healthy eyes. Another nutrient important in the fight against free radicals is vitamin C. One cup of zucchini contains well over 20% of the daily recommended value for this immune system-boosting vitamin. Vitamin C is also essential in the production of collagen, which gives skin its elasticity and youthful look. Manganese, of which around 10% of the daily value is present in a one-cup serving of zucchini, is also essential in collagen production and as an antioxidant. Furthermore, it is involved in the production of bone tissue.

Manganese isn’t the only mineral found in zucchini that promotes healthy bones. Also gained from eating zucchini are magnesium, which is essential in bone metabolism, and phosphorus, which teams up with calcium (also found in zucchini) to strengthen bones. These bone-friendly minerals help prevent problems such as osteoporosis and osteoarthritis.

One risk associated with consuming zucchini is that it contains oxalates. While oxalates are produced naturally in the body, excessive amounts can crystallize, leading to kidney stones. Therefore, it is not generally recommended to eat too much zucchini in one sitting. Another potential problem related to zucchini is that of pesticide residue. Zucchinis are known to contain high amounts of residue, which have been linked to a wide range of side effects including ADHD and CNS damage. To avoid this, we recommend buying organic and making sure to thoroughly wash the zucchini before use. Soaking your produce in a 10% / 90% vinegar-water solution is a surefire way to wash away most of the residue.

Possible short-term side effects

  • when consumed in excessive amounts, oxalates can crystallize, leading to an increased risk of kidney stones

Possible long-term side effects

  • pesticide residue:
  • cancer
  • adhd (in children)
  • colon problems
  • alzheimer’s disease
  • nervous system damage

Ingredients to be aware of

  • oxalates
  • pesticide residue


  • help rehydrate
  • promotes eye health
  • promotes bone health
  • promotes skin help
  • fights free radicals
  • reduces the risk of cancer
  • reduces risk of osteoporosis and osteoarthritis

Toxic Squash Syndrome: Here’s What To Know And How To Avoid It

You may not have heard the word Cucurbitaceae before, but chances are you’ve eaten some before. Cucurbits are a gourd family of flowering plants that include cucumbers, melons, squash and pumpkins, which can be delicious, healthful foods to enjoy in your diet. However, they could also make you quite ill if you’re not careful.

Squash can contain a toxic compound called cucurbitacin E., which can cause cucurbit poisoning, also known as toxic squash syndrome (not to be confused with toxic shock syndrome) in people who ingest it.

A March 2018 report published in the Journal of the American Medical Association tells of two French women who became quite ill and experienced massive hair loss following unrelated cases of cucurbit poisoning.

There’s no need to rid your kitchen of every zucchini or cucumber. Although it can be quite serious, cucurbit poisoning is also very rare. Learning how it occurs, how to avoid it and what to do if you should ever contract toxic squash syndrome can help you protect yourself and your family.

How Squash Becomes ‘Toxic’

Plants in the Cucurbitaceae family produce the toxin cucurbitacin as a natural defense against insects. While wild squash, cucumbers and other cucurbits can contain substantial amounts of cucurbitacin, the cultured varieties typically contain such a small amount that it doesn’t affect humans.

“Wild cucumbers contain relatively large concentrations of cucurbitacin and are highly bitter,” said Oregon State University vegetable breeder Jim Myers. “While their domestic cousins we grow in the garden and buy in the store, tend to have less but varying amounts of the bitter compound.”

Cross-pollination with wild plants as well as some type of stress during growth, such as lack of adequate water or poor fertilization, are some of the factors believed to cause increased cucurbitacin in squash and other produce.

Avoiding Toxic Squash Syndrome

You’ll likely know a bad vegetable when you taste it, as plants with a high concentration of cucurbitacin are extremely and unpleasantly bitter. If you bite into squash and experience a nasty flavor, spit it out and stop eating. Eating even a few pieces can cause you to become violently ill and endure terrible side effects.

Since cross-pollination is a contributing factor to large concentrations of cucurbitacin, do not eat squash that you are unfamiliar with, either. For instance, if your garden produces “volunteer” zucchini or acorn squash that you did not plant, or you also grow ornamental pumpkins and gourds alongside squash, avoid eating them.

Symptoms of Toxic Squash Syndrome

If you have eaten even just a few bites of exceedingly bitter squash, pumpkin, cucumber or another member of the cucurbit family, watch for these symptoms:

  • Abdominal Pain
  • Diarrhea
  • Nausea
  • Vomiting
  • Dizziness while standing

In addition, substantial hair loss can occur several weeks after curcurbitacin poisoning. The two women noted in the JAMA report experienced hair loss from their scalps and bodies that took several months to regrow. However, researches stated that these are the first known cases of hair loss caused by cucurbit poisoning.

Cucurbit Poisoning Treatment

In most cases, cucurbit poisoning will run its unpleasant course much like other instances of food poisoning. However, in 2015 a German man died and his wife was hospitalized after eating a significant amount of toxic zucchini in a stew.

Seek medical attention if you become dehydrated, have excessive pain or dizziness, experience ongoing stomach issues or believe you have consumed more than a bite or two of food containing high amounts of cucurbitacin.

All About Zucchini
Zucchini is a summer squash, much like pumpkins and eggplant. Zucchini are similar to cucumbers in appearance, but have a very different texture. They range from light green to very dark green (almost black) in color and can even have stripes. Zucchini can grow to be over a foot, but are harvested at different sizes around the world. In the United States, zucchini is typically harvested when it is between 5 and 8 inches long (approximately 2 to 7 days after flowering), but in South Africa the fruit is harvested when it is still very small (about the size of your finger) and is called ‘baby marrows’.
Squash is separated into two categories: summer squash and winter squash. Summer squash has a high water content and thin edible skin. Zucchini is the most popular of summer squashes and is “in season” from May until August, but can be found in the grocery store all year long. Smaller, younger zucchini have more flavor, so pick one that is firm with a glossy, unblemished skin. You can store your zucchini for up to five days in the refrigerator.
Fruit or Vegetable?
Although zucchini is typically treated as a vegetable, when it comes to culinary situations, it is technically a fruit. The zucchini itself is actually the swollen ovary of the zucchini flower. Zucchini was first introduced in the Americas, but the zucchini that we know and love today was developed in Italy many generations after they were originally introduced. Unlike many other fruits, zucchini does not have a large amount of natural sugar, but it does have a high water content and is low in calories. It is also a good source of folic acid, potassium, and vitamins A and C.
Just like every other fruit, there are many varieties of zucchini ranging in color, size, length of time to produce and texture. White squash, or summer squash, is sometimes seen as a mutation of the zucchini and is even found on the same plant as its’ green relatives. Originally, zucchini was only grown in its traditional long cylindrical version, but newer varieties have surfaced more recently to meet the ever growing demand of cooks near and far. Golden zucchini and globe zucchini are the newest varieties of zucchini that have been grown for commercial purposes. Golden zucchini is the same shape as traditional green zucchini, but has a lighter color and a lighter flavor. Globe zucchini, on the other hand, is green in color but is spherical, more similar to a pumpkin. These globe zucchinis are about 3 inches in diameter on average and are perfect for stuffing.
Zucchini Flowers
Zucchini flowers are one of a select few edible flowers. The flowers, also called courgette flowers, can be eaten raw or cooked. I typically think of myself as someone who has tried plenty of exotic or out of the ordinary foods, but zucchini flowers are something I had never even thought of eating. This recipe from The Picky Eater for Baked Zucchini Flowers with a Creamy Ricotta Filling definitely changes my mind about that. I’ll be gathering a few flowers from the garden right after I finish writing this!
Zucchini is a vegetable that is delicious by itself but I can also be used for a variety of meals anywhere from breakfast to dessert after dinner. Because its flavor isn’t exceptionally strong, zucchini can be added or baked into traditional recipes to give it a hint of flavor and some added health benefits. Chilled zucchini soup during the summer is a refreshing way to try something new.
How to Cook it
Because its currently summer, I love to throw some zukes on the grill. A little butter or olive oil and seasoning are all you need. If grilling isn’t your forte, or maybe its winter, you can cook your zucchini a few other ways. Zucchini can be baked in the oven with other vegetables or by itself with olive oil and spices. It can also be sautéed on the stove to make a delicious vegetable side for any meal. Deep fried zucchini fritters are a delicious snack and are slightly healthier than French fries.
The Best Seasonings for Zucchini
When you think of seasoning fruits and vegetables, typically salt and pepper come to mind instantly, but there are a few other ways to spice up your zucchini and they are even salt free. Basil and oregano go incredibly well with zucchini and so do some of our seasoning blends. Our Roasted Garlic Pepper is fantastic for garlic lovers and our Habanero Garlic Pepper is made especially for cooks who are always looking for an added kick.
Any way you slice it, zucchini is a great addition to so many dishes and even great on it’s own with a few seasonings. The next time you see them at a roadside stand or farmers market make sure to pick up a few and try out a healthy new recipe. It might surprise you how versatile zucchini can be!

I planted green zucchini. The plant is huge and has lots of zucchini on it,…

Hello and thank you for using Ask an Expert. Well this might come as a surprise, but

Yellow zucchini develops a golden color as it grows.

Yellow zucchini is a variety of summer squash, just like regular zucchini. The main difference between green and yellow zucchini is the color of the skin. The golden color develops as the fruit grows. This warm season annual needs frost-free weather to grow properly. Growing yellow zucchini provides the home gardener an inexpensive source of summer squash.

I wouldn’t let the squash get large and I would remove the larger yellow ones now. If you want to eat them you can. It would be better if you picked the squash when it is smaller and not wait for it to turn green. I really don’t have an answer for your question. Other than getting the wrong seeds have you fertilized the plants? Good luck and enjoy.
