Benefits of Spices and Herbs in Nutrition

As dietitian nutritionists, we are often asked about macronutrients (carbohydrates, proteins and fats) and micronutrients (vitamins and minerals). However, there are other ingredients that impact one’s health in a powerful way. These ingredients are called herbs and spices. They play an integral role in the flavor of one’s food and provide valuable nutrition for the body. Keep in mind the difference between spices and herbs. Herbs are the fresh leafy parts of the plants, whereas spices are derived from the dried root, bark and seeds of the plant.

Spices and Herbs in Cooking

Now you know which herbs and spices are associated with different cuisines. This can be helpful when you’re preparing your favorite dishes whether it be Pad Thai or tacos. You might also notice that there is overlap between these ingredients and different cultures. Here’s a look at the most used herbs and spices with a focus on their food pairings. I also specify the benefits of these spices and herbs.

A bunch of the fresh herb, basil


This herb is most often used in salad dressings, sauces and marinades. It pairs well with eggplant, potatoes, tomatoes, zucchini and bell peppers. You can add it to chicken, fish or pork and serve it with cheese.

Benefits: Basil is loaded with antioxidants which serve to protect your cells from damage. Animal studies indicate benefits in cognitive function, cancer prevention and cardiovascular health. (1-5) Basil is loaded with various vitamins and minerals including magnesium.

Emily’s Favorite Use of Basil: I use this spice to prepare my homemade tomato-less tomato pasta sauce. This sauce is made primarily of carrots and onions with a hint of beet to create a red color.

Four rolls of cinnamon sticks are piled next to a small mound of the ground up spice


This spice is a sweet yet earthy blend that pairs itself well with fruit, starchy vegetables such as sweet potatoes and squash, as well as proteins like chicken and lamb.

Benefits: Cinnamon has been used for centuries due to its medicinal characteristics. This single ingredient is loaded with antioxidants and has anti-inflammatory benefits. (6-10) Studies have shown that cinnamon can impact cardiovascular health, control blood sugar and may impact cognitive function. (11-16) There are two types of cinnamon, but the preferred source is Ceylon cinnamon as it is more pure compared to its counterparts.

Emily’s Favorite Use of Cinnamon: It’s hard to say no to a cinnamon roll! A healthier use of this spice is with cooked apples. Cooked apples can be used in a variety of ways. You can eat them by themselves or they can be used as a topping for ice cream, oatmeal, or vanilla yogurt. I prefer to eat them with roasted pork.

Five bulbs of garlic are set in a cloth and basket


You might be surprised to learn that garlic is considered a vegetable but is often used as a spice in the form of a powder. Due to its savory nature it is best used with mushrooms, beans, animal protein, soups, sauces, and marinades.

Benefits: This spice is a nutritional powerhouse. It includes a variety of vitamins and minerals as well as antioxidants. Evidence shows it protects against cardiovascular disease, cognitive dysfunction and cancer. (17-22) Some advocates claim it is vital to immune support. (23)

Emily’s Favorite Use of Garlic Powder: If I’m not using fresh garlic then I’m using garlic powder. Garlic is used in almost every dish in my house. You might be surprised to know that I use it to flavor butter, guacamole, hamburger sauce and chutney. Yum!

Multiple pieces of ginger root are set upon a cutting board along with bits of ground up spice


This spice provides a sweet and comforting flavor profile to food. It works well with all animal protein and soy, but it can also be used with starches like rice and sweet fruits and vegetables including carrots, beets, citrus and squash.

Benefits: Most people use ginger to ease an upset stomach or reduce nausea. (24) This is due to its main compound called gingerol. However, gingerol can also reduce inflammation. By reducing inflammation, an individual may experience improved digestion, heart health, blood sugar control, brain function and weight management. (25,26)

Emily’s Favorite Use of Ginger: My go-to use for powdered ginger is in an Asian marinade for flank steak. I like to mix it with soy sauce or coconut aminos (soy free soy sauce substitute), honey, Worcestershire sauce, Dijon mustard, garlic and salt and pepper. It’s a hit every time.

A fresh herb plant of oregano grows outside


This earthy herb is used by many different cultures. It deepens the flavor of mushrooms, potatoes, bell peppers, tomatoes, artichokes, beans, and animal protein. You can’t go wrong by adding oregano to most dishes.

Benefits: Oregano is often used by integrative and functional practitioners to fight infections and bacteria. (27) It is another rich source of antioxidants which are key in protecting the human body from cell degradation and disease. (28-30)

Emily’s Favorite Use of Oregano: This spice is used in most of my broth-based soup recipes. It adds extra earthiness to a simple combination of ingredients taking soup from ordinary to extraordinary. I have also found that the extra oregano in my garden is a nice addition to any floral bouquet.
