While most people are familiar with celery stalks as a crunchy vegetable, celery seeds often remain overlooked despite their remarkable nutritional profile and health-promoting properties.
These tiny, light-brown seeds carry a warm, slightly bitter flavor and an earthy aroma that makes them a popular spice in many cuisines. Beyond their culinary applications, celery seeds have been valued in traditional medicine systems for centuries, used to address various health concerns ranging from respiratory issues to inflammatory conditions.
Today, celery seeds are available both as a cooking spice and in concentrated forms such as supplements, extracts, and capsules. Despite their small size, these seeds deliver substantial nutritional value and offer numerous science-backed health benefits.
Let’s explore six remarkable benefits of celery seeds and how you can incorporate them into your wellness routine.
1. Packed with Essential Nutrients
Celery seeds may be small, but they deliver an impressive array of essential nutrients that support overall health.
These seeds are particularly notable for their mineral content, including calcium, manganese, iron, magnesium, and phosphorus. They also provide a balanced combination of macronutrients.
A single tablespoon (approximately 6.5 grams) of celery seeds contains:
- Calories: 25
- Carbohydrates: 2 grams
- Protein: 1 gram
- Fat: 2 grams
- Dietary Fiber: 1 gram
- Calcium: 12% of the Daily Value (DV)
- Manganese: 27% of the DV
- Iron: 17% of the DV
- Magnesium: 9% of the DV
- Zinc: 6% of the DV
- Phosphorus: 5% of the DV
The low-calorie nature of celery seeds combined with their nutrient density makes them an excellent addition to a balanced diet. The relatively equal distribution of carbohydrates, protein, and fat provides a well-rounded nutritional profile.
2. Strengthen and Support Bone Health
Strong, healthy bones depend on adequate intake of specific vitamins and minerals throughout life. Celery seeds contain several key nutrients that contribute to bone health and may help prevent bone-related diseases.
Calcium is perhaps the most recognized mineral for bone health. With 12% of the daily value in just one tablespoon, celery seeds provide a plant-based source of this critical mineral. When dietary calcium is insufficient over extended periods, the body draws calcium from bones, potentially reducing bone mineral density and increasing fracture risk, particularly in older adults.
Manganese is another standout nutrient in celery seeds, with one tablespoon providing 27% of the daily value. This trace mineral activates enzymes responsible for producing proteins necessary for bone tissue and cartilage formation, thereby supporting bone structure and strength.
Magnesium and phosphorus are also present in celery seeds. These minerals work together to support osteoblasts, the specialized cells responsible for building new bone tissue. Deficiencies in either nutrient have been linked to increased risk of osteoporosis and other chronic bone conditions.
Research suggests that maintaining adequate intake of these bone-supporting minerals may help preserve bone density and reduce fracture risk as we age.
3. Support Healthy Red Blood Cell Production
Iron plays an indispensable role in producing red blood cells, which transport oxygen from the lungs throughout the body. Without sufficient iron, the body cannot manufacture adequate red blood cells, potentially leading to iron-deficiency anemia.
Celery seeds serve as an excellent plant-based iron source. One tablespoon provides approximately 17% of the daily value for women and 38% for men, making them particularly valuable for those following plant-based diets.
Iron deficiency represents the most common micronutrient deficiency globally. Including iron-rich foods like celery seeds in your regular diet can help prevent deficiency and reduce the risk of anemia.
It’s important to note that celery seeds contain non-heme iron, the form found in plant foods, which is absorbed at a lower rate than the heme iron found in animal products. To maximize absorption of non-heme iron, consider pairing celery seeds with vitamin C-rich foods such as citrus fruits, berries, tomatoes, or bell peppers. Vitamin C significantly enhances the body’s ability to absorb plant-based iron.
4. Help Regulate Blood Sugar Levels
Maintaining healthy blood sugar levels is crucial for preventing type 2 diabetes and reducing cardiovascular disease risk. Celery seeds contain magnesium, a mineral that plays a vital role in blood sugar regulation.
With one tablespoon providing 9% of the daily value for magnesium, celery seeds can contribute to your magnesium intake. This mineral enhances cellular response to insulin, the hormone responsible for regulating blood sugar levels.
Research has consistently shown that diets rich in magnesium are associated with better blood sugar control. Large-scale studies have found that people who consume magnesium-rich diets have up to 14% lower risk of developing type 2 diabetes compared to those with lower magnesium intake.
While celery seeds alone won’t prevent diabetes, incorporating them as part of a balanced, nutrient-rich diet may support healthy blood sugar metabolism and contribute to overall metabolic health.
5. Possess Natural Antibacterial Properties
Emerging research suggests that celery seed extract may exhibit antibacterial properties against certain harmful microorganisms.
Test-tube studies have demonstrated that celery seed extract can combat Helicobacter pylori (H. pylori), bacteria found in the digestive tract that can cause stomach ulcers in some individuals. Additionally, research has shown antibacterial activity against various other bacteria, yeasts, and mold strains.
These antimicrobial properties have led researchers to investigate celery seed extract’s potential as a natural food preservative, offering an alternative to synthetic preservatives.
However, it’s important to note that most research on celery seeds’ antibacterial effects has been conducted in laboratory settings. More human studies are needed to confirm these benefits and determine effective dosages for therapeutic use.
6. Provide Powerful Antioxidant Protection
Celery seed extract appears to possess significant antioxidant properties, which may help protect cells from damage caused by free radicals.
Free radicals are unstable molecules that can damage cells, proteins, and DNA. While some free radical production is normal, excessive amounts can contribute to chronic diseases. Antioxidants neutralize free radicals, helping maintain the delicate balance necessary for optimal health.
Research conducted in test tubes and animal studies has shown that celery seed extract demonstrates antioxidant activity. This is likely due to the presence of polyphenols, beneficial plant compounds found in celery seeds.
Polyphenol-rich diets have been associated with lower rates of cancer, heart disease, diabetes, and other chronic conditions in large population studies. While celery seeds contain these beneficial compounds, more human research is needed to fully understand their antioxidant effects when consumed as part of a regular diet.
How to Incorporate Celery Seeds Into Your Diet
Celery seeds are remarkably versatile and easy to add to your daily meals. They’re available in several forms:
- Whole seeds: Can be used as-is or toasted for enhanced flavor
