There seem to be more opinions on optimal eating patterns than there are stars in the sky. So when a major scientific contribution to nutrition comes out, it’s important to take note.

Such a report was published in a major medical journal this week: It’s the largest study ever comparing animal protein sources (red meat, poultry, fish, eggs, and dairy) with plant-based protein sources (bread, cereals, pasta, nuts, beans, and legumes). It examined over 130,000 participants, spanned 32 years, and was authored by some of the world’s leaders in longevity and nutrition (Dr. Walter Willett of the Harvard School of Public Health and Dr. Valter Longo of the University of Southern California). In other words: Before you express any opinion on what your breakfast, lunch, and dinner should comprise, you need to pay proper attention to this study first.

Here’s what you need to know:


A group of 131,342 participants in the Nurses’ Health Study and the Physicians Health Study was followed from as early as 1980 until 2012. They completed questionnaires about their dietary intake, and the follow-up rates were an amazing 95 percent. Overall, there were 36,115 deaths with 8,851 due to cardiovascular disease (CVD), 13,159 from cancer, and 14,105 from other causes.
