What Happens if You Don’t Eat Vegetables?

Will it really be that bad if you don’t eat your broccoli? (It could be, yes.)

In all likelihood, you spent your childhood being told — in no uncertain terms — to eat your broccoli and spinach. Whether you grew up hating them or just don’t feel like you have enough time to work them into your diet as an adult, you may not be in the habit of getting greens on your plate.

Especially if you’re a strength athlete and like to focus on your protein intake, it’s all too easy to skip the veggies and go right to the heart of the meal. But a lot happens to your body when you don’t eat enough vegetables. Here, you’ll learn about the risks of not eating vegetables and how to get enough veggies in your diet.

Risks of Not Eating Enough Vegetables

There are many complex factors related to access to affordable vegetables. Individuals and communities who live in food deserts — areas without affordable, readily-available access to fresh food — are also likely to be exposed to economic and environmental stressors that can contribute to poor health outcomes. (1)(2)(3)(4)(5

In addition to regional inequity in fresh vegetable availability in the United States, nationwide vegetable supply across the globe is often lower than what is required to meet the recommended intake for adults. (6)

Because of these complexities, it can be hard to tell which factors are responsible for which health outcomes. (3)(7) Still, research does suggest that there are direct, negative health impacts of not getting enough veggies in your diet. (7)

Higher Risk of Diseases

It’s not just about clearing your plate because your parents are telling you to. Eating enough vegetables daily can help reduce your risk of getting non-communicable diseases — that is, diseases that aren’t contagious, like heart disease and cancer. (7) Inadequate vegetable intake has been linked to a greater risk of asthma, hypertension, strokes, pancreatic diseases, cardiovascular diseases, anemia, and colon, liver, lung, and rectal cancer. (7)(8)(9)(10)(11)(12)(13)

Increased Mortality Rate

Given the extensive list of diseases that one is at risk for when they don’t eat enough vegetables, it perhaps isn’t surprising that all-cause mortality rates go up as vegetable intake goes down. (14)(15)(16)(17)

Eating more fruits and vegetables is associated with lower all-cause mortality rates, especially cardiovascular-related mortality. (14)(15)(16)(17)

Reduced Mental Health

Depression has been associated with inadequate vegetable intake. (7)(18) Research suggests that an increase of 100 grams of vegetable intake per day may reduce the risk of depression by three percent. (19) There has also been some research linking less than four daily servings of vegetables to the experiences of people with psychosis. (20)

Benefits of Eating Vegetables

They might not always be the part of the meal you’re most looking forward to, but getting your vegetables can be quite a delicious experience. It’s also one of the best things you can do for your health. Here’s why.

Lower Risk of Disease

Diets that include five servings per day of cruciferous vegetables (think: broccoli, cauliflower, cabbage, and Brussels sprouts) and dark-green leafy vegetables (like collards and kale) have been linked to significantly lower rates of cardiovascular disease. (21)

Eating enough vegetables seems to have a protective effect against chronic diseases like diabetes, different cancers, cardiovascular diseases, and even Alzheimer’s disease. (22) Similarly, it stands to reason that since low vegetable intake is associated with higher disease rates across the board, eating more vegetables can have a positive impact on your overall health and lower the risk of disease. (7)(8)(9)(10)(11)(12)(13)

Improved Mental Health

Eating your greens may not just be good for your body. It can also be good for your mind. Research suggests that eating enough vegetables — especially green leafy vegetables — is associated with lower rates of depression and psychological distress. (18)(20)(19)(7)

There isn’t a cut-and-dry case of cause and effect between mental health and vegetable consumption. However, there does seem to be a clear correlation between eating five servings of vegetables each day and improved mental health. (18)(20)

How Many Servings of Vegetables Do You Need Per Day?

The World Health Organization (WHO) and the Food and Agricultural Organization (FAO) recommend eating a minimum of 400 grams of fruits and vegetables per day — that totals about five servings (two and a half to three cups) each day. (23)

However, once you hit your recommendation, you don’t have to eat even more. Research suggests that the benefits taper off around five servings per day. (14) So while you should aim for five servings of vegetables each day, eating more than that won’t necessarily give you added benefits. (14)(21)

But if steamed broccoli or raw carrot sticks aren’t your things, don’t despair. Even 100-percent vegetable juice and processed veggies “count” toward your recommended daily intake. (23) And in case you were wondering — you definitely were — potatoes also contribute to the mission of getting enough veggies.

How to Eat More Vegetables

You might be busy bustling between kids, personal time, and your job — or you just haven’t liked veggies in the past and don’t see a way forward. Either way, it can feel like a chore to get to that benchmark of five servings per day. Here’s how to make it easier to eat more vegetables.

Buy Frozen or Canned Veggies

Accessing and affording fresh veggies can be tough. Opt for bags of frozen vegetables or canned veggies (preferably without additives) to keep in the freezer or pantry. Frozen veggies are relatively easy to cook in a pan — just slap on the pan’s lid and cook them at medium heat, stirring occasionally. You can also roast them, put them in a slow cooker, or even pop them in an air fryer.

Frozen and canned veggies go in pretty much anything, from stir fries and casseroles to quiches and pasta. Nutritionally, frozen and canned vegetables tend to have just as many nutrients as their fresh counterparts. (24) They’re also typically much more cost-effective than buying fresh produce, too. (24)

Prioritize Your Plate

Check out your plate every time you make a meal for yourself. Is it 50 percent vegetables? If not, you may be missing out on your vegetable needs.

When you’re putting your meal together, put vegetables on the plate first. Then, try to fill it with 50 percent veggies. If it’s a meal like breakfast where veggies don’t always feel like the intuitive star of the show, try integrating some into your eggs or morning soup. 

Stacking your plate with veggies first will help make portioning easier and ensure that you’re getting enough greens. If you find yourself still hungry, feel free to go back for seconds.

Eat Vegetables First

Eating your vegetables first with each meal may help you get a higher veggie intake total each day. (25) The study in question was conducted with pre-schoolers, suggesting that kids who ate the vegetables on their plate before eating anything else were the ones who overall got more veggies each day. (25)

It might be tempting to dismiss this kids-oriented study as not applying to grown-ups with jobs and 500-pound deadlifts. But research suggests that people’s attitude about vegetables is influenced by what they learned and felt about veggies growing up. (26)(27) So take a lesson from the kiddos in the study and eat your vegetables first.

Find the Veggies You Like

Contrary to what you might have thought as a child, vegetables don’t have to be bland or taste bad. That said, not everyone has to like every food. So it’s important to find out what vegetables you like and how to prepare them in a way that tastes good to you

Research shows that people who find vegetables boring or don’t like the taste are less likely to eat them. (28) To conquer this barrier, take some time to figure out which vegetables you don’t like and which ones you do. 

Experiment with different ways of preparing veggies to make them taste good to you. You might hate spinach in salads, but love it when it’s cooked with a little sriracha.

You can also get veggies through 100-percent vegetable juices and other processed sources like dried veggies and vegetables in powdered form. (23)(29) So if you need to supplement your intake with 100 percent carrot juice and some greens powder, have at it.

Get Social Support

Accessing fresh vegetables can be tough enough. Learning to prepare them in a way you like can also be a journey. Make it easier on yourself by recruiting social support to help you stay on track with your vegetable goals. Research suggests that a lack of social support can contribute to inadequate vegetable intake. (30

Set yourself up for success by treating your nutrition like your strength training sessions. Get yourself the equivalent of a gym buddy to help keep both of you accountable to your veggie-intake goals.

Have That Broccoli

If vegetables are the bane of your nutritional existence, it’s not just you. Adults all around the world have trouble getting their recommended daily intake of five servings, even when veggies are readily available. But that doesn’t mean all is lost.

Ward off the negative health impacts of inadequate vegetable intake by finding which veggies you like, making them tasty, and having at least two and a half to three cups each day.
