After analyzing over 5,800 foods, researchers have found that eating a hot dog could cost you 36 minutes of healthy life, while opting for a serving of nuts instead could gain you up to 26 minutes.
The resulting data will no doubt prove useful for anyone who's keen to figure out how to eat healthily.
In addition to frankfurters, the list of foods that can shorten your life included other processed meats such as corned beef (71 minutes lost), fried foods such as a portion of three chicken wings (3.3 minutes lost) and vegetable pizza (1.4 minutes lost).
Meanwhile, foods identified as actively lengthening life included fish high in omega-3, such as baked salmon (15 minutes gained) and sardines in a tomato-based sauce (82 minutes gained). Perhaps somewhat surprisingly, peanut butter and jelly sandwiches also made the list (up to 33 minutes gained), thanks to their high nut content.
The study, conducted by the University of Michigan, made use of the Health Nutritional Index (HENI), a new database developed to make the health and nutritional data more accessible. Using HENI, you can calculate the impact on your health associated with a serving of various foods, measured in minutes.
The index was created by adapting the Global Burden of Disease, a data tool designed for policymakers and healthcare providers, and combining it with food profiles taken from the What We Eat in America database.
Each food was assigned a score, with positive values adding healthy minutes and negative scores considered as having a detrimental impact on your health. Whilst this is interesting in its own right, but the researchers also linked the foods to their environmental impact.
This included how the item was produced, processed, distributed, and cooked. By combining the health and environmental analysis, the team categorized the foods into traffic light-style categories.
To improve your health and protect the planet, the advice is to up your servings of green zone foods. Foods in the red zone are best avoided due to their negative impact on the environment and your health. Examples of both are listed below.
Green zone foods
- Field-grown vegetables
- Whole grains
- Sustainably-sourced seafood
Red zone foods
- Processed meats
Despite tackling the analysis from a different angle, the researchers found what many others before them have; for our health and the sake of the planet, we should be reducing our intake of red and processed meats and switching to a primarily plant-based diet.
Helpfully, changing your diet is good for your wallet too, as vegan meals are 40% cheaper than meat dishes. So, if you've been thinking about making the switch and need some inspiration, consider getting yourself some of the best vegan cookbooks to get started.
