3 Health Benefits of This Chicken and Mushroom Soup

#1: Antioxidant-Rich

Antioxidants are an essential part of your body’s defense system. Everyday life will induce some level of oxidative damage. While this may sound threatening, it’s actually quite normal, and your body is set up to handle it.

Issues arise, however, when the natural oxidative processes in your body aren’t met with antioxidants to keep them at bay.

The best way to get antioxidants? Through diet.

Onions happen to be an excellent source of antioxidants[*]. They’re specifically rich in the flavonoid quercetin, known for its effects on inflammation and immunity. Quercetin has been studied for a wide range of beneficial effects, including anti-carcinogenic, anti-inflammatory, and antiviral[*].

#2: Supports Heart Health

There’s a lot of contradicting information and opinions out there as to how diet affects the health of your heart. In addition, there seems to be a lot of confusion as to what markers matter and which ones play a lesser role in the pathology of heart disease.

Among the confusion is the debate around cholesterol. What most people don’t understand is that LDL cholesterol on its own is not necessarily a bad thing.LDL cholesterol that’s been oxidized, however, can become dangerous.

Research shows that certain types of fat can actually protect your LDL cholesterol from oxidation. Olive oil, for instance, can modify your LDL make-up, resulting in a particle that is resistant to oxidative stress.

This creates an antiatherogenic particle. In other words, it neutralizes it from being a threat to the health of your heart[*]

#3: High Protein

Everyone knows that to build a strong physique, you need to eat enough protein. What many people don’t realize, however, is that consuming enough protein is also essential to building strong immunity.

One of the main components of your immune system is known as T cells. These immune cells need protein in order to function properly. T cells play a major role in defense against bacteria and viruses, leaving you vulnerable to opportunistic infections when protein intake is diminished[*].

In addition, individual amino acids influence your immune system in more tissue-specific ways. Arginine, for instance, is an amino acid which has been shown to enhance immune mechanisms in those with compromised immune systems[*].

Along with decreased immunity, low protein intake is also associated with muscular weakness, vascular dysfunction, and anemia[*].

Luckily, this chicken mushroom soup provides you with 33 grams of protein per serving.
