3 Health of Benefits of Keto Spaghetti Sauce
Aside from its fantastic taste and easy-to-make convenience, this keto marinara sauce is loaded with nutrients and health benefits. Read on to learn about some of the benefits from the ingredients in this low-carb pasta sauce.
#1. Boosts Immunity
Supporting your immune system isn’t just for flu season.
Strong immunity is your ticket to energy and the ability to fight infection and disease as you age. Nutrition plays a huge role in the strength of your immune system.
Oxidation plays a massive role in your immune system. The stronger your antioxidant force, the more likely you are to fight off everything from the common cold to more serious diseases like cancer[*].
But antioxidants aren’t the only stars in this immunity show.
A group of phytochemicals known as carotenoids are abundant in tomatoes. Among many other health benefits, carotenoids have been studied for their potential to protect against breast cancer[*].
Statistics say that one in eight women will develop breast cancer in their lifetime. One way to help protect your body is to add more potent phytochemicals like carotenoids[*].
The bright red peel of tomato contains a flavonoid called naringenin. Naringenin has been studied for its anti-inflammatory activity and protective effect against a wide variety of diseases. Most studies to date have been done in animal models, but more research is certainly warranted[*].
The essential oil of oregano contains a compound called carvacrol. Carvacrol is an analgesic, which means it can provide pain relief similar to when you take a pain reliever[*].
Among the pain-relieving activities of carvacrol are its anti-inflammatory effects, which have been demonstrated in mouse models[*].
Oleic acid, a monounsaturated fatty acid, has also been shown to increase insulin sensitivity in animal models[*].
In addition, olive oil contains a compound called oleocanthal which works similarly to ibuprofen in your body[*].
#3. Heart Healthy
If you’ve ever heard of the doctrine of signatures, then it won’t surprise you that tomatoes are great for your heart. The doctrine of signatures states that a food or herb that resembles a part of your body is healing for that part of the body[*].
Tomatoes are red, and when you slice them in half, they contain four chambers — just like your heart.
But you don’t need to count on the doctrine of signatures.
The lycopene in tomatoes also enhances antioxidant activity in people with coronary heart disease[*].
The olive in this recipe is another big player when it comes to heart health. Not only is olive oil consumption linked with lower blood pressure, but it may also improve the integrity of your blood vessels[*].
In a review of 140,000 people, researchers found that olive oil consumption also significantly reduced the risk of stroke[*].
