3 Health Benefits of Lasagna Soup

#1: Skin Protective

Before you slather on another coat of SPF you may want to check in with your diet — food has a significant impact on the health of your skin.

And when it comes to skin-loving foods, tomatoes are one of the most impactful.

When you consume foods that are high in antioxidant compounds like carotenoids and flavonoids, they travel to the tissues in your body that are most exposed to light. Here they protect your tissues from UV damage.

Tomatoes are rich in the plant compound lycopene, which is a type of carotenoid. Studies show that ingestion of lycopene, or tomato derived products that are rich in lycopene, can have a significant effect on skin health.

In fact, after 10-12 weeks of intervention, lycopene appears to decrease sensitivity towards UV light-induced sun damage. In this way, it acts as an internal sunscreen[*].

#2: Supports Heart Health

The health benefits of garlic could be a post all its own. However, one of the most well-studied benefits of consuming garlic is its impact on cardiovascular health.

It should come as no surprise that the quality of your diet impacts this essential and delicate organ. Consuming foods that are anti-inflammatory and high in antioxidants is an integral part of your overall health — particularly your heart health.

Consuming garlic regularly has a cholesterol-lowering effect, and also decreases serum triglycerides. While cholesterol on its own is not necessarily a cause for alarm, when cholesterol becomes oxidized, it can lead to complications like atherosclerotic plaques.

One study found that consuming garlic for two months led to an 8% reduction in total serum cholesterol. The researchers reported that this number is associated with a 38% reduction in the risk of coronary events for people 50 years of age and older[*].

#3: Balances Blood Sugar

When following a keto diet, one of your primary goals is to keep your blood sugar low, so you can keep your ketones high. The way to manage this? Through food.

Onions are a great source of the antioxidant and anti-inflammatory compound quercetin. Quercetin is a powerful compound that’s well known for its protective effects against diabetes, cancer, neurodegenerative diseases, and heart disease.

As an anti-diabetes agent, quercetin may lower blood glucose by inhibiting glucose absorption in the small intestine. It also seems to assist in the release of insulin and improves the utilization of glucose by peripheral tissues. In other words, it helps your cells take in glucose to be used as fuel instead of just hanging out in your blood[*].
