Despite the growing popularity of diets low and high in carbohydrates, research published in&nbsp;The Lancet&nbsp;found that both are linked to increased mortality.&nbsp;One arm of the long-term, multi-cohort study&nbsp;&ndash; the Atherosclerosis Risk in Communities (ARIC) study &ndash;&nbsp;used data from 15,428 male and female United States adults aged between 45 and 64 years. These participants&nbsp;all reported a non-extreme daily caloric intake (men: &lt;600 kcal or &gt;4,200 kcal per day, women: &lt;500 kcal or &gt;3,600 kcal per day).&nbsp;At a median follow-up of 25 years, 6,283 ARIC participants had died. Data from the ARIC cohort found that those with a 50-55% carbohydrate intake had the lowest rates of mortality. Analyzing data across the entire study, which contained 432,179 participants, low and high carbohydrate intake (&lt;40% and &gt;70%, respectively) were both associated with increased mortality when compared with moderate carbohydrate intake (low carbohydrate consumption hazard ratio [hr] 1.20, high carbohydrate&nbsp;hr&nbsp;1.23).&nbsp;<blockquote class="twitter-tweet" data-width="500" data-dnt="true">

</blockquote><script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>Researchers found that not all nutrients are created equal, though. When carbohydrates were&nbsp;replaced&nbsp;by protein&nbsp;and fat&nbsp;from animal sources, mortality increased (hr&nbsp;1.18), and it decreased&nbsp;when plant-based alternatives were chosen (hr&nbsp;0.82).&nbsp;Macronutrient ratios impacted life expectancy as well. A 50-year-old with moderate carbohydrate intake could expect to live for an additional 33.1 years. For low- and high-carbohydrate dieters, life expectancy was 29.1 and 32 years, respectively.&nbsp;<blockquote class="twitter-tweet" data-width="500" data-dnt="true">
