Is Squash High In Vitamin K? 🌱
Is squash high in Vitamin K? This is a question that often arises among those who are keen to balance their dietary intake, particularly when it comes to essential nutrients. In this comprehensive exploration, I’ll dive deep into the relationship between squash and Vitamin K, providing clear, factual insights.
Understanding Vitamin K and Its Importance
Vitamin K is a crucial nutrient, primarily known for its role in blood clotting and bone health. It comes in two natural forms: Vitamin K1 (phylloquinone) and Vitamin K2 (menaquinone). Vitamin K1 is primarily found in green leafy vegetables, while Vitamin K2 is more abundant in animal products and fermented foods. The body absorbs Vitamin K2 more effectively, but both forms are vital for maintaining good health.
Squash Varieties and Vitamin K Content
Squash, a versatile and popular vegetable, comes in various types. These include butternut, acorn, spaghetti, and summer squash. But how does squash fare in terms of Vitamin K content? Let’s break it down:
- Butternut squash contains about 1.1 mcg of Vitamin K per 100g serving.
- Acorn squash offers slightly less, with 0.9 mcg per 100g serving.
- Spaghetti squash has even lower levels at 0.6 mcg per 100g serving.
- Summer squash contains 2.8 mcg per 100g serving.
Clearly, squash is not a high source of Vitamin K. However, it’s interesting to note that cooking squash can slightly increase its Vitamin K content.
Squash Compared to Other Vegetables
When it comes to Vitamin K content, squash doesn’t quite match up to the levels found in other vegetables. For example, spinach boasts a significant 483 mcg of Vitamin K per 100g serving, and broccoli comes in at about 101.6 mcg.
Table 1: Vitamin K Content in Different Squash Types (per 100g)
| Type of Squash | Vitamin K Content (mcg) |
| Butternut | 1.1 |
| Acorn | 0.9 |
| Spaghetti | 0.6 |
| Summer | 2.8 |
The Role of Vitamin K in Squash Varieties
In squash, Vitamin K predominantly exists as K1. The content varies depending on factors like the squash variety, cooking method, and serving size. Winter squashes like acorn and butternut generally have more Vitamin K1 than summer varieties like zucchini and yellow squash. Also, cooking methods like steaming and boiling tend to preserve Vitamin K better than roasting or frying.
Squash in the Vitamin K Landscape
Despite containing Vitamin K, squash is not considered a “high-vitamin-K” food. This is evident when compared to leafy greens that are rich in Vitamin K1. For instance, kale contains 157 mcg of Vitamin K1 per 100g, while acorn squash has only 7 mcg.
Table 2: Vitamin K1 Content in Squash and Other Vegetables (per 100g)
| Vegetable | Vitamin K1 Content (mcg) |
| Kale | 157 |
| Collard Greens | 102 |
| Broccoli | 81 |
| Brussels Sprouts | 75 |
| Acorn Squash | 7 |
| Butternut Squash | 5 |
| Zucchini | 3 |
| Yellow Squash | 2 |
The Benefits of Squash’s Low Vitamin K Levels
Squash, while not rich in Vitamin K, still offers several advantages:
- Supporting Balanced Intake: Including squash in your diet contributes to a diverse Vitamin K intake.
- Contributing to Daily Needs: Varieties like acorn and butternut squash can contribute to the daily recommended intake of Vitamin K (90 µg for adults).
- Safe for Certain Medications: Squash’s low Vitamin K content is beneficial for individuals on blood thinners, as it minimizes potential drug interactions.
Alternatives to Squash in Low Vitamin K Diets
Looking beyond squash, other vegetables also offer low levels of Vitamin K. Sweet potatoes, onions, carrots, tomatoes, and eggplants are such examples. Squash, however, with slightly higher K1 levels, stands out as a valuable choice in the low-K1 vegetable category.

| Vegetable | Vitamin K1 Content (mcg) |
| Sweet Potato | 2 |
| Onion | 2 |
| Carrot | 3 |
| Tomato | 4 |
| Eggplant | 3 |
Vitamin K Content in Various Squash Preparations
The way squash is prepared can impact its Vitamin K content. Let’s look at the differences in Vitamin K1 content in some popular squash varieties based on their preparation methods.
Table 4: Vitamin K1 in Squash Varieties by Preparation (per 100g)
| Squash Variety | Raw | Cooked (Steamed/Boiled) | Roasted |
| Acorn | 9 | 7 | 6 |
| Butternut | 7 | 5 | 4 |
| Zucchini | 3 | 2 | 1 |
| Yellow Squash | 2 | 1 | 1 |
Squash and Daily Vitamin K Intake
While squash contributes to daily Vitamin K intake, its contribution is relatively modest, especially when compared to other vegetables like leafy greens.
Table 5: Vitamin K Content in Squash vs. Daily Recommended Intake
| Source | Vitamin K Content (mcg) |
| Adult Men (AI) | 120 mcg |
| Adult Women (AI) | 90 mcg |
| Summer Squash (1 cup) | 4 mcg |
| Spinach, cooked (1 cup) | Approx. 888 mcg |
| Kale, cooked (1 cup) | Approx. 1062 mcg |
| Broccoli, cooked (1 cup) | Approx. 220 mcg |
