Spinach vs Broccoli: Which is Better? A Complete Comparison


Part of being a Certified Health Coach is to inform people about healthy foods like spinach and broccoli. Many of my clients ask me which one is preferred. Let’s answer, which is better, spinach or broccoli?

Spinach is better than broccoli due to its higher percentage of B vitamins and minerals. Spinach has less calories and carbohydrates making it better for weight loss and low-carb diets. Spinach has a lower glycemic index than broccoli and can be used in more raw dishes than broccoli like sandwiches.

This article will start with a side-by-side comparison of their nutrients. In addition, I’ll examine their tastes, textures, prices, whether one can substitute for the other, glycemic indexes and health benefits.

Nutrient Resources 1 2

After examining the table above it’s obvious both vegetables are nutrient dense. Between both, which one has more nutrients?

Spinach has a higher percentage of nutrients than broccoli. Spinach provides more protein, vitamin A, beta carotene, vitamin K, B6, folate, thiamin, riboflavin, niacin, magnesium, potassium, iron, copper, calcium and zinc than broccoli. 

This isn’t to say broccoli doesn’t provide many nutrients because it does. Broccoli contains a good number of those nutrients and provides more of the following than spinach:

  • Fiber
  • Vitamin C
  • B5
  • Phosphorus

Which to Choose?

Since both vegetables are nutrient dense, the one you may want to consume more often may depend on your particular goals. Let’s examine four of the more popular goals.

Low-carb or Keto Diets

If you’re considering one of these diets, the number of carbs each food contains may make a huge difference as far as which one you eat more often. Therefore, let’s examine which one has more carbohydrates.

Broccoli has 6.64 grams of carbohydrates, and spinach has 3.63 per 100 grams. Broccoli provides 3.01 grams more of carbs. That’s 83% more per 100 grams making spinach better for low-carb diets. 

Losing Weight

If your goal is weight loss, the number of calories per serving is important. Let’s examine how many calories per serving each one contains.

Broccoli has 34 calories, and spinach has 23 calories per 100 grams. Broccoli provides 11 more calories than spinach. While this number may not seem like much, it equals 48% more calories making spinach better for losing weight.

Bodybuilding

If gaining lean muscle mass is your goal then the amount of protein and carbohydrates may matter to you.

Extra healthy carbs help to fuel energy and increase performance when exercising or lifting weights. It’s why marathon runners consume much spaghetti the day before the big race.

Any extra protein helps to repair and build new muscle after putting them through a good workout. Therefore, let’s take a closer look at which is better for bodybuilding.

Broccoli is better than spinach for bodybuilding due to its higher percentage of carbs and similar number of protein. Broccoli provides 2.82 grams of protein and spinach 2.86 grams per 100 grams. Broccoli provides 83% more carbohydrates per 100 grams. 

If you’re consuming carbohydrates through another food source then both are good options for bodybuilding.

Gluten Free

If you’re consuming a gluten free diet or have celiac disease, this can make or break your choice between the two. Between each one, which is gluten free?

Broccoli and spinach are gluten free. Therefore, if you only consume a gluten free diet, both of them are good options.

Prices

With inflation affecting the prices of just about everything lately, the cost of food certainly matters to most people. For this reason I decided to take a closer look at which food costs more.

Spinach and broccoli have a similar price. The cost for spinach averages $0.16 per ounce and broccoli averages $0.16 per ounce. 

To conduct some original research, I visited some local supermarkets and compared the prices of each one. Here are my findings.

First I checked a Walmart Supercenter:

  • Marketside bagged fresh spinach
    • 10 ounce bag for $1.98. Equals $0.20 per ounce
  • Marketside fresh broccoli florets
    • 32 ounce container for $6.18. Equals $0.19 per ounce

I then checked my local Shoprite supermarket:

  • Bowl and basket chopped spinach frozen
    • 10 ounce bag for $1.29. Equals $0.13 per ounce
  • Bowl and basket broccoli florets frozen
    • 16 ounce bag for $2.00. Equals $0.13 per ounce

Tastes and Textures

Sometimes the nutrients or price doesn’t matter much. If you don’t like the way a food tastes it will probably remain on the store shelf. Therefore, let’s take a look at how the taste of each one compares to each other.

Spinach has a mild taste when raw and becomes more bitter when cooked. Broccoli tastes slightly bitter, earthy and mildly sweet. Raw broccoli is more bitter than cooked. The texture of spinach is thinner and softer than the thicker and tougher broccoli.

I wanted to conduct original research on the topic and get the opinion of people like yourself. So I reached out to my clients, readers and members of food groups. I asked them, which one tastes better?

  • 40% said they preferred the taste of spinach.
  • 52% said they preferred the taste of broccoli.
  • 8% said it depended on their mood.

In the battle of taste, broccoli was the winner over spinach.

Substitutions

For those times when you only have one of the two foods available, let’s find out if broccoli can be used instead of spinach.

Broccoli and spinach can substitute for each other in most dishes although the taste and texture will be different. Cooking times will be longer when substituting broccoli for spinach unless it is used raw. Broccoli is not a good substitute for spinach on sandwiches, wraps or pizza toppings.

More than a one to one ratio of spinach to broccoli will have to be used when cooking. This is so because spinach leaves break down and lessen the volume of food when cooked.

Leafy greens make a better spinach substitute like the following:

  • Arugula
  • Bok choy
  • Swiss chard
  • Butterhead lettuce
  • Collard greens
  • Green leaf lettuce
  • Romaine
  • Beet greens
  • Watercress
  • Kale

The best broccoli substitutes include the following:

  • Cauliflower
  • Brussels sprouts
  • Asparagus
  • Kale
  • Green beans
  • Green cabbage
  • Collard greens

Glycemic Index

Avoiding blood sugar spikes is an important part of consuming healthy food. This is true for diabetics or anyone worrying about their health 3. For this reason, the glycemic index of food is important.

The Glycemic Index (GI) is a scale measuring how fast a particular food raises the blood sugar in the blood 4. Blood sugar spikes can lead to health complications with the heart, nerves, kidneys and eyes 5

Foods on the GI scale are categorized as:

  • Low-GI foods: 55 or under
  • Medium-GI foods: 56-69
  • High-GI foods: 70 or over

How blood sugars levels are affected:

  • Foods with a glycemic index 70 or more cause a quicker spike in blood sugar levels.
  • Foods with a glycemic index 56 to 69 cause a moderate spike in blood sugar levels.
  • Foods with a glycemic index 55 or less cause a slow spike in blood sugar levels.

Knowing more about the glycemic index of food and how it raises blood sugar, many people wonder which one has a higher glycemic index.

Spinach has a lower glycemic index than broccoli but both are considered low GI foods and shouldn’t cause much of an increase in blood sugar.

Spinach Health Benefits

Magnesium

  • Spinach provides 276% more magnesium than broccoli per 100 grams.

Magnesium helps the body control the following:

  • Nerve function
  • Blood pressure

One reason many people supplement with magnesium in the evening is because it helps calm the whole body including blood vessels.

Magnesium helps keep blood pressure levels stable and balanced. Recent scientific research examined previous studies and concluded magnesium supplementation decreased systolic and diastolic blood pressure 7.

In the heart and muscles, magnesium competes with calcium to help the muscles relax after contracting. When the body is low in magnesium, calcium can over stimulate the heart muscle’s cells causing a rapid or irregular heartbeat 8.

B Vitamins

Spinach provides a higher percentage of five of the six B vitamins listed below.

The B vitamins provided include the following:

  1. B1 (thiamin) 
  2. B2 (riboflavin) 
  3. B3 (niacin) 
  4. B5 
  5. B6 
  6. B9 (folate) 

B vitamins help support the following:

  • Digestion.
  • Brain function.
  • Energy levels.
  • Red blood cells.
  • Nerve function.
  • Cardiovascular disease.

Vitamin A & Beta Carotene

  • Spinach provides 1,400% more vitamin A than broccoli per 100 grams.
  • Spinach provides 1,450% more beta carotene than broccoli per 100 grams.

Beta-carotene is a compound present in both foods. The body converts beta-carotene into vitamin A.

According to scientific studies, vitamin A helps the eyes when it comes to dim light vision and dry eyes 9.

Besides eye health, an increased number of vitamin A has been shown to fight and prevent cardiovascular disease, which is the leading cause of death in the United States 10.

In addition, vitamin A is a powerful antioxidant that can help reduce cellular damage by controlling the negative effects of free radicals 11.

Potassium

  • Spinach provides 76% more potassium than broccoli per 100 grams.

Potassium helps the body reduce excess fluid therefore reducing blood pressure 12.

According to Harvard Health, a number of studies have shown a connection between low potassium levels and high blood pressure 13. The more potassium, the more sodium your body will lose.
