What vegetable is highest in fat? The surprising truth

4 min read

While most people consider avocados and olives the highest fat 'vegetables', they are botanically classified as fruits. In reality, many true vegetables contain almost no fat, leaving a surprising legume at the top of the list for highest fat content among non-fruit produce.

Quick Summary

Uncover the highest fat vegetables, differentiating between culinary and botanical definitions. Explore the high fat content of avocados and olives, and learn which true vegetables, like soybeans, contain notable amounts of beneficial fats.

Key Points

  • Avocado and Olives: The highest fat produce commonly called 'vegetables' are botanically fruits, packed with healthy monounsaturated fats.

  • Soybeans are the Highest True Vegetable: Among genuine vegetables, cooked soybeans (or legumes like edamame) have the most significant fat content, around 9 grams per 100g.

  • Fat is Important for Nutrient Absorption: Healthy fats are essential for absorbing fat-soluble vitamins (A, D, E, K), which are plentiful in many vegetables.

  • High-Fat Plant Foods are Healthy: The fats in avocados and olives are beneficial for heart health and can help reduce bad cholesterol.

  • Culinary vs. Botanical Definitions Matter: The confusion stems from the different ways botanists and cooks classify fruits and vegetables, based on their biology versus their culinary use.

  • Corn Contains Moderate Fat: Another true vegetable, corn, contains a moderate amount of fat (around 1.5g per 100g) compared to other vegetables.

The Botanical vs. Culinary Divide: An Important Distinction

When asking 'what vegetable is highest in fat?', the answer depends on whether you're using a culinary or botanical definition. Botanically, a fruit develops from the flower's ovary and contains seeds, while vegetables consist of other plant parts like stems, leaves, and roots. This crucial distinction is the reason why the most commonly cited high-fat produce items, avocados and olives, are not technically vegetables at all. From a culinary standpoint, their savory flavors and use in main courses lead them to be treated as vegetables.

The Top Contenders: Avocado and Olives (Botanical Fruits)

Both avocados and olives are renowned for their high, heart-healthy fat content, but they are botanically classified as fruits.

Avocado: The Creamy Powerhouse

Often called a 'butter fruit' for its texture, the avocado (technically a single-seeded berry) is exceptionally high in healthy fats.

  • Fat Content: A 100-gram serving of avocado contains approximately 15.4 grams of fat.
  • Fat Type: The fat in avocados is predominantly monounsaturated, specifically oleic acid, the same type found in olive oil. This type of fat is known to help lower bad (LDL) cholesterol levels when consumed in place of saturated fats.
  • Nutritional Benefits: Beyond its rich fat profile, avocado is a great source of fiber, potassium, and vitamins K, C, and E. These nutrients work together to support heart health and reduce inflammation.

Olives: A Mediterranean Staple

Olives, like avocados, are drupes (stone fruits) used widely in savory dishes.

  • Fat Content: A 100-gram serving of olives contains about 10.7 grams of fat.
  • Fat Type: Olives are another excellent source of monounsaturated fats, which are a cornerstone of the heart-healthy Mediterranean diet.
  • Health Benefits: Olives also provide a significant amount of vitamin E, iron, copper, and antioxidants, which help protect the body from oxidative stress.

Highest-Fat True Vegetables

Ignoring the botanical anomaly of avocados and olives, a few legitimate vegetables stand out for having a higher fat content than their counterparts, though the amounts are modest in comparison.

Soybeans and Edamame

  • Soybeans: Cooked soybeans are a legume with one of the highest fat concentrations for a true vegetable. A 100-gram serving typically contains around 9 grams of fat, with a healthy balance of polyunsaturated and monounsaturated fatty acids.
  • Edamame: These immature soybeans, often served in the pod, contain less fat per serving than mature soybeans but are still a notable source for a vegetable, with about 5 grams of fat per cup.

Corn

Often enjoyed as a starchy side dish, corn is another vegetable with a slightly elevated fat content.

  • Fat Content: A 100-gram serving of cooked yellow corn contains approximately 1.5 grams of fat.
  • Fat Composition: This is higher than most other cooked vegetables, though still quite low overall. Corn oil, extracted from the germ of the kernel, is another well-known culinary product derived from its fat content.

Comparison of High-Fat Plant Foods

To put these numbers into perspective, here is a comparison of fat content per 100-gram serving for several plant-based foods, including the botanical fruits often mistaken for vegetables.

Food Type Botanical Classification Fat (g) per 100g
Avocado Fruit ~15.4
Olives Fruit ~10.7
Soybeans (cooked) True Vegetable (Legume) ~9.0
Corn (cooked) True Vegetable ~1.5
Broccoli True Vegetable ~0.4

Why Fat is Important in Your Diet

While low-fat diets were once popular, it's now widely understood that not all fats are created equal. The healthy, unsaturated fats found in foods like avocados and olives are essential for overall health.

  • Nutrient Absorption: Fats are crucial for the absorption of fat-soluble vitamins (A, D, E, and K), meaning you need to consume some fat to properly utilize the vitamins in other vegetables.
  • Cell Function: Healthy fats are vital components of every cell membrane in the body and are essential for proper brain and nerve function.
  • Satiety: Adding healthy fats to meals can help you feel full and satisfied for longer, which can be beneficial for weight management.

Conclusion

In summary, the highest fat 'vegetables' are actually the fruits, avocado and olives, which are packed with beneficial monounsaturated fats. Among true vegetables, soybeans and corn contain the most fat, though in much smaller amounts. Embracing these high-fat plant-based foods as part of a balanced diet can provide a wide range of vitamins, minerals, and healthy fats that are crucial for overall well-being. The distinction between a culinary and botanical vegetable is important, but what matters most is incorporating nutritious foods into your diet in a way that is both healthy and enjoyable.

Frequently Asked Questions

Avocado is botanically a fruit, specifically a single-seeded berry, because it develops from the flower of the avocado tree. It is used culinarily as a vegetable due to its savory flavor.

Olives are botanically classified as fruits, specifically drupes or stone fruits. Like avocados, their savory flavor and use in cooking lead them to be treated as vegetables in a culinary context.

If you exclude botanical fruits like avocado and olives, soybeans (a legume) contain the highest fat content among common vegetables, with about 9 grams of fat per 100-gram serving.

The common confusion arises from culinary traditions, where sweet items are typically fruits and savory items are vegetables. Since avocados and olives are used in savory dishes like salads and main courses, they are often mistakenly considered vegetables.

Yes, the fat found in avocados and olives is predominantly monounsaturated fat, which is considered heart-healthy. This type of fat can help lower bad cholesterol levels and reduce the risk of heart disease.

While most vegetables are low in fat, incorporating fat-rich items like avocados, olives, soybeans, and nuts can help ensure you get sufficient healthy fats on a vegetarian diet. Nuts, seeds, and oils are other important plant-based fat sources.

Besides soybeans, other true vegetables with more fat than average include corn (around 1.5g per 100g) and edamame (immature soybeans), though the amounts are still modest compared to fruits like avocado and olives.
