Spices are known for imparting flavor, but they are also an integral part of maintaining health and preventing disease! The medicinal value of spices has been recognized for thousands of years by the ancient Indian medical system known as Ayurveda.1 Since many diseases are a result of weak immune systems or chronic inflammation, preventing these two states can make a big difference in your health.
The immune response is a built-in defense system, protecting the body from foreign invaders and infection by communicating between cells and their chemical signals. While our skin is the outer shield of our bodies, our gut mucosa serves as the internal barrier. What we eat (especially nutrients, alcohol, coffee, spices, and salted food) affects this barrier, which is the starting point of most immune responses. It’s true that a healthy immune system can ward off infection from cold-causing germs. However, our immune systems are also activated by the longer-term stimuli of physical stress, psychosocial stress or malnutrition.2
Chronic low-grade inflammation is a prolonged and abnormal immune response of altered cell communication that does not resolve itself, leading to ill health and a variety of life-threatening conditions.2,3 This “silent inflammation” is connected to several diseases of advanced age such as heart disease, diabetes, arthritis, Alzheimer’s and certain cancers.4 Persistent inflammation is also involved in the development of obesity (and associated metabolic complications), inflammatory bowel disease, asthma, and rheumatoid arthritis.2,3,5 Inflammation of the nervous system plays a key part in neurodegenerative diseases, mood disorders (including depression and anxiety), and pain.2
Beneficial Spices
Spices come from the roots, bark, and seeds of the plant, while herbs* are the leaves. Essentially, any part of the plant that is not a leaf and can be used for seasoning may be considered a spice.
Spices and other medicinal plants have many bio-active compounds. Some have antibiotic properties (boosting our innate immunity against infections) and others are anti-inflammatory agents.5,6,7 Nutraceuticals present in several spices have shown potential to inhibit or reverse inflammatory responses and help prevent many chronic diseases related to sustained inflammation:
