What Are Capers?

If you are still wondering “What is a caper?'' The answer is simple — flower buds. Capers are essentially the immature flower buds of a plant called the Capparis Spinosa. These are small bush-like plants that grow in countries like Spain, Greece, and Italy (1). They are a major part of making Mediterranean dishes. Apart from making the food super tasty and flavorful, they are packed with nutrients and may aid weight loss, and hair growth and even help manage blood sugar levels.

Handpicking delicate, cream-white flower buds in the early morning hours is standard practice. The buds are cleansed and left to wilt in the sun for a few hours after harvesting them. Post this, the buds may be placed in jars and coated with salt, brine, olive oil, or vinegar.

The size of capers may vary, some may be as big as a peppercorn while others may be as tiny as an olive. How you use them in food may depend on whether you want a strong flavor or just the aroma. If you want the aroma using small capers will do the task and if you want a peculiar flavor the big ones are recommended.

Nutritional Value of Capers

Capers are generally used in small quantities and hence each serving may contain a low amount of calories and fewer amounts of fat, proteins, and carbs. 

According to the USDA one tablespoon of canned Capers may contain the following nutrients (2): 

  • Calories - 2
  • Fiber - 0.3 grams
  • Protein - 0.2 grams
  • Carbs - 0.4 grams
  • Copper - 4% of the Daily Value (DV)
  • Sodium - 202 mg

Sodium is essential for maintaining fluid balance and blood pressure levels (3). Copper is a vital mineral involved in iron metabolism, energy production, and brain function (4). Capers also include a small amount of vitamin K, a micronutrient in your body that is responsible for blood clotting and bone health (5). 

13 Amazing Health Benefits of Capers

1. May Help with Weight Loss

While capers may add flavor to your food one of the major health benefits of capers is that they are low in calories. This makes them an excellent food to add to your weight loss diet. Explaining more about the benefits of capers, our contributor Mary Sabat, RDN, and Ace Certified Trainer, says, “Capers are not typically considered a "superfood" for weight loss, but they can be a healthy addition to a weight management diet. They are low in calories and rich in fiber, which can help with satiety and controlling appetite.” Losing weight can benefit people’s health in general as well and hence, capers can be added to your low-calorie food. You can swap your high-calorie ingredient for capers to add flavor. This may decrease your daily calorie intake, leading to effective weight loss (6).

2. May Help Fight Inflammation in the Body 

Antioxidants are compounds that help neutralize free radicals that can be harmful to the cells in your body and prevent cell damage (1), (7). According to research, capers is an excellent source of antioxidants such as quercetin and rutin (1). Some research suggests that antioxidants could also reduce inflammation. 

They can also then help protect against diseases like cancer, heart disease, and type 2 diabetes (7). Both quercetin and rutin are well-researched compounds and have been shown to alleviate inflammation, manage blood sugar levels, and enhance wound healing (8). According to a recent study, quercetin has analgesic, anti-inflammatory, antibacterial, and anti-carcinogenic activities which can help fight inflammation in the body (9).

3. May Help with Diabetes

Another health benefit of capers that may make you consider using them in your diet is that they may help with managing diabetes. There is some evidence that suggests the compounds in capers may help with maintaining blood sugar levels. Our contributor Mary Sabat, sheds some light on this topic, saying, “Eating capers may help manage diabetes due to their low glycemic index and potential to improve blood sugar control. Capers are rich in fiber and antioxidants, which can slow down carbohydrate digestion and reduce post-meal blood sugar spikes.” As per one literature review, specific components contained in capers may support improved blood sugar regulation by decreasing carbohydrate absorption, and protecting insulin-producing cells in the pancreas (10).

Another small study done on 30 diabetics also found that taking a tonic containing caper extract three times per day helped avoid rises in blood sugar and lipid levels (11). Similarly, an older study of 54 persons who had diabetes also discovered that taking caper fruit extract three times a day for two months resulted in significant improvements in long-term blood sugar management and fasting blood sugar levels when compared to those in a control group (12). 

However, more research is needed to understand how capers affect blood sugar levels when consumed in moderation as part of a healthy diet. It is also important to note that if you are already on diabetes management medication, it may be best to avoid capers as both lower blood sugar levels (13). 

4. Rich in Minerals

Capers contain a large variety of minerals like calcium, iron, and copper, that can be beneficial for the body (14). 

Iron aids in the storage and utilization of oxygen by our muscles. It is a component of numerous enzymes that aid in the digestion of food in our bodies. Calcium on the other hand aids in the formation of strong bones and teeth (15). Copper reacts with specific proteins to form enzymes that act as catalysts in a variety of biological functions.

5. Rich in Vitamins

One other health benefit of capers is that they provide you with a rich source of a variety of vitamins. Capers contain niacin, Vitamin K, Vitamin A, and riboflavin that boosts your overall health (14). Riboflavin, often known as vitamin B2, aids the body in converting food into energy. 

It is also thought to help with adrenal function. As a result, it contributes to the maintenance of a healthy nervous system (16). Vitamin A is an important nutrient as it is responsible for improving eyesight. It also helps us see things in the dark. It may also lower the risk of developing some malignancies. This necessary vitamin aids in the fight against illness and boosts the immune system. 

Vitamin K is essential for bone health. It reduces the likelihood of blood clotting. Niacin plays an integral part in protecting you from cardiovascular diseases. It may help decrease cholesterol and improve cognitive, neurological, and digestive processes (17).

6. May Help Fight Bad Enzymes 

If you are someone who consumes red meat, then capers may just be a good addition to your diet. This is because capers destroy specific by-products contained in meat and fat-rich diets. These byproducts are frequently linked to health diseases (18).

According to Dt. Deepti Lokeshappa, Senior Consultant, Nutritionist, and Dietitian, Motherhood Hospital, Bangalore “Capers are a good source of certain nutrients and compounds that may have anti-inflammatory properties, such as quercetin, rutin, and other flavonoids. These compounds have been studied for their potential to reduce inflammation in the body. It's important to note that while capers may offer some potential benefits, they are not a substitute for medical treatment or other lifestyle changes that are often recommended for managing rheumatism symptoms.” An animal study conducted in 2016 also found that caper extracts could help relieve pain related to rheumatoid arthritis (21).

9. May Help Deal with Flatulence

Capers may also be beneficial in reducing stomach aches and flatulence (22). Along with this, they may also be used to improve your appetite. 

10. May Help with Congestion 

A lot of people suffer from excessive phlegm or mucus production, which accumulates in the chest and respiratory passageways. This causes chest tightness, pain in the chest, and other symptoms. Capers help to keep the respiratory tract healthy by removing extra mucus or phlegm and relieving congestion (23). 

11. May Help Manage Dry Skin Problems

Well if you thought that the health benefits of capers were only limited to your body, you may just be wrong! They are also great for your skin. Capers can work well for you if you have dry skin (14). 

12. May Promote Hair Growth

Capers are also commonly utilized in hair care products due to their high vitamin B and iron content. Both are known to stimulate hair growth. Deficiency of vitamin B and iron is known to cause hair loss, adding capers to your diet can help you fight hair loss and get stronger tresses (24). 

13. May Help Improve Bone Health

Capers play a pivotal role in bone health. Capers include a high concentration of Vitamin K, which aids with bone density. It aids in the prevention of bone-related diseases such as osteoporosis and arthritis, which occur as a result of reduced bone density (25).
