Things to watch for

Depending on how they are prepared and stored, capers can be a major source of sodium. This is the reason why you should consume them in limited quantities as a source of flavor for nutritious meals.

Benefits of capers

Capers enhance flavor and are an excellent option for people looking to cut calories but still enjoy tasty meals.

Beyond these capers provide a variety of health benefits such as:

May stabilize blood sugar

One of the major benefits of cappers is that they are rich in fiber. Adding capers to your diet is a great way to bump up fiber intake. Fiber helps slow the absorption of sugar in the bloodstream to keep blood sugar levels stable in the long term and promote glycemic control.

A 100 grams of canned capers provide about 3.2 grams of fiber which is a great amount (total dietary fiber intake should be 25 to 30 grams a day from food).

Furthermore, some research has found that certain components of the caper plant may have anti-diabetic properties as well. A study from 2013 published in Complementary Therapies in Medicine found that caper fruit extract was effective at lowering blood sugar in people with diabetes.

This study is promising but was conducted by using caper fruit extract. So, more research is needed on how capers can affect blood sugar in the amounts found in food. This promising research shows that capers could be a beneficial addition to a diabetic diet plan.

Antioxidant powers

Free radicals can build up in the body to damage DNA, proteins, and important fatty molecules. Antioxidant compounds present in capers can prevent this.

The most abundant antioxidant molecules of capers are:

  • rutin
  • quercetin
  • kaempferol
  • pronathocyanidins
  • carotenoids
  • Vitamin E and C

Capers are one of the plant sources of flavonoid compounds rutin and quercetin. They are the largest source of rutin, 100 grams contain 332 mg of this compound.

Rutin helps in the smooth circulation of blood and it can be very helpful in treating strained blood vessels.

Also, capers are very rich in quercetin second only to tea leaf. Quercetin has analgesic, anti-inflammatory, and antibacterial properties.

Good source of vitamin K

Another benefit of consuming capers is their high vitamin K content. Adults need approximately 1 microgram a day of vitamin K for each kilogram of their body weight. For example, a person who weighs 75 kg would need 75 micrograms a day.

A single ounce (28g) of capers provides about 9% of the daily recommended intake. Vitamin K is especially important when it comes to blood clotting.

This vitamin is necessary for the function of several proteins involved in the process of coagulation. It is vital for preventing excess bleeding to promote recovery and healing.

In addition to this when paired with other vitamin K foods such as leafy greens, Brussel sprouts, adding capers to your daily diet may help maintain bone health.

A 2013 study published in the American Journal of Clinical Nutrition showed that a low intake of vitamin K in the diet was associated with low bone mineral density.

Rich in minerals

Capers are rich in minerals like copper, iron, calcium, and high levels of sodium. The high sodium level is mainly due to the addition of sea salt in the brine.

  • Copper combines with certain proteins to produce enzymes that act as catalysts to help a number of body functions.
  • Calcium helps in building stronger teeth and bones.
  • Iron helps our muscle to store and use oxygen. it’s part of many enzymes that help our body to digest food.

Potential risks and side effects of capers

Capers are rich in sodium and eating too much can easily put you over your daily limit. A common sign of eating excess capers is extreme thirst. So try to consume it in moderate amounts.

If you suffer from high blood pressure you should avoid eating capers. Excess sodium increases blood volume since it retains water.

To decrease the amount of sodium in each serving of capers it is good to soak them from 3 to 5 minutes and then rinse them thoroughly. This helps remove excess salt and reduce sodium intake. It also helps bring out their unique flavor and aroma.

Allergy: Another possible side effect of capers is that they contain a chemical that is also found in mustard oil. If you are allergic to mustard oil be cautious when trying capers.

Pregnancy and breastfeeding: There isn’t enough information to know if capers are safe to use when pregnant or breastfeeding. It is better to avoid them when pregnant or breastfeeding.

Difference between capers and “non-pareil” capers

Capers are sold by size. The smallest caper will have the most delicate texture and better flavor. A larger caper is more acidic.

The smaller the caper the more delicate in texture and flavor it is. The smallest variety of capers is about 1/4-inch or 7 mm in diameter. It is from the south of France. Called French non-pareil, they are the most prized and come with an equally noticeable price tag.

Non-pareil capers are the best in flavor and texture. If the jar does not say “non-pareil” your capers will be a little tougher, larger, and not as delicate.
