Cayenne pepper is a staple of spicy dishes but in addition to sprucing up certain meals, it has also has been shown to provide protective benefits.

Research shows that capsaicin, the active ingredient in cayenne pepper, reduces appetite, and increases fat burning.

Obesity is linked to a number of life-threatening developments, such as heart disease and some types of cancer so it is vital to keep it at bay.

One study found that adding one gram of red pepper to meals reduced appetite and increased fat burning in people who did not regularly eat peppers.

Some animal studies have also found capsaicin to combat certain forms of cancer, including lung, liver, and prostate cancer.

Turmeric spice that is derived from the ginger family has been shown to offer some protection against a number of health threats.

The magic ingredient is a bioactive compound found in turmeric called curcumin, which is thought to help maintain brain, heart, and lung function, as well as protect against cancers and age-related diseases.

Curcumin is also linked to an increased lifespan in both insects and mice.

Cinnamon is often used to give an added oomph to many dishes but a compound found in the spice called cinnamaldehyde is responsible for its medicinal benefits.

Cinnamon has potent antioxidant activity, helps fight inflammation, and has been shown to lower cholesterol and triglycerides in the blood.

Cholesterol and triglycerides are types of fat found in your blood that can clog up your arteries and raise your risk of heart disease.

Cinnamon’s protective benefits are most pronounced in its effects on blood sugar levels, however.

Cinnamon can lower blood sugar by several mechanisms, including by slowing the breakdown of carbs in the digestive tract and improving insulin sensitivity.

Studies have shown that cinnamon can lower fasting blood sugars by 10-29 percent in diabetic patients, which is a significant amount.

Why Is It Important To Lower Blood Sugar Levels?

Consistently high blood sugar levels raise your risk of developing type 2 diabetes, a chronic condition that can lead to heart disease.

If you are already diagnosed with type 2 diabetes, consuming cinnamon is also a great way to keep your blood sugar levels in check, staving off the risk of deadly complications.

Research suggests the effective dose is typically 0.5-2 teaspoons of cinnamon per day or one to six grams.
