Diet is one of the first things most people think about when it comes to longevity. We’ve compiled the top three scientifically proven diets for increasing your healthspan.
When it comes to developing your physical longevity, you're going to see a lot of different diets peddled towards you. Unfortunately, a lot of these diets fail to pass the snuff test in long-term research. That being said, there is one notable exception to this; that is the Mediterranean diet, a diet developed in the United States back in the 1980s to reflect the healthy nature of many Mediterranean villages in comparison to modern cities. You can learn more about the Mediterranean diet here.
Plant-rich diets lower risk of premature death. There's many reasons this could be true, but it's likely tied to the lack of processing essential molecules go through within plants as opposed to herbivores (or worse, carnivores).
There isn’t any specific diet that handles plant-based foods. Instead, try some experiments with increasing our vegetable intake; this includes "eating across the rainbow", which is seen as a good indicator of increasing the nutrient diversity for our diet. If you don’t want to go deep into a vegan diet at the start, you can try starting with other diets that are plant heavy -- such as the Mediterranean diet!
The Longevity Diet was created by Valter Longo, a professor at the University of Southern California. In 2018, a book was published detailing the specifics of the diet to the public, and the book has caught on since.
Reading a brief summary of the diet on Valter Longo’s page, we can say that the diet does in fact check out -- though it's perhaps more specific and detailed than would be helpful for a beginner diet. Because of this, we recommend The Longevity Diet as a more advanced routine for someone who wants to take their already existing diet regime to the next level.
