Fresh rosemary makes a beautiful decoration, so if you’re headed to the grocery store be sure to pick up a few sprigs to finish off the meal.

The Health Benefits of this Pork Loin Roast

#1. Boosts Cancer Defenses

As you probably already know, garlic is a miracle ingredient for heart health and inflammation. Research has uncovered many health benefits of garlic, but perhaps most impressive of all is its potential effect on cancer cells.

In one study, researchers examined the effect that garlic had on lung cancer cells and found that a compound in garlic was able to induce cell death in the cancerous cells[*].

This is just one of many studies calling out garlic as a potential anti-cancer agent[*][*][*].

#2. Supports Muscle and Skeletal Health

Eating enough protein is essential for your muscle and skeletal health, and this recipe naturally provides a boost in protein with pork being the main ingredient.

Protein is vital for physical strength and mobility. It helps build new muscle mass, can help repair damaged muscles after physical activity, and is essential for bone strength[*][*].

#3. Promotes Mental Health and Brain Function

Rosemary has been widely researched for its ability to improve brain health, as well as memory and recall[*][*].

Antioxidants and anti-inflammatory compounds in rosemary may even benefit people suffering from Alzheimer’s disease. These compounds seem to inhibit the death of brain cells, which give them neuroprotective properties[*].
