A number of studies have found that vegetarian diets are associated with a modestly reduced risk of developing cancer compared with diets that include meat.

For example, a major analysis of nearly 80,000 adults found about a 12 percent lower overall risk of cancer among vegetarians, and even greater reductions for specific cancers like stomach (up to 45 percent lower) and lymphoma (about 25 percent lower).

While no diet guarantees cancer prevention, these findings suggest that regularly choosing plant-based meals may offer important long-term health benefits.

Here are four delicious vegetarian recipes you can enjoy this weekend:
