Cruciferous vegetables get their name from the Latin word cruciferae, which means “cross-bearing,” because the flowers of cruciferous plants are said to resemble a cross. You may hear these plants referred to as brassica vegetables, too.
To study the connection between food and health, researchers collected diet and lifestyle information from 134,796 healthy adults, who were 40 to 74 years old at the start of the study. The 73,360 women in the study were followed for approximately ten years, while the 61,436 men were followed for an average of four years.
After taking into consideration other factors that can affect health and risk of death, such as cigarette and alcohol use, weight, exercise habits, and a history of heart disease, stroke, high blood pressure, or diabetes, the researchers found:
In this study, the women who ate the most vegetables averaged 166 grams of cruciferous and 506 grams of total vegetables per day. The men who ate the most vegetables averaged 208 grams of cruciferous and 583 grams of total vegetables per day.
A cup of chopped broccoli weighs approximately 150 grams, which means the people eating the most vegetables overall—which includes all types of vegetables, cruciferous and others—averaged one to two servings of cruciferous vegetables and three to four servings of total vegetables each day. This is an achievable goal for most of us.
This study agrees with much of what we already suspect about nutrition and health, especially that eating more total and cruciferous vegetables, lowers risk of death due to all causes and due to heart disease in particular. Below are tips on making veggies a part of your daily eating plan.
