The table illustrates data about seven types of calories consumed by U.S. residents daily during three distinct periods from 1970 to 2010.
Overall, it can be seen that the total intake exhibited an upward trend over the given period. Specifically, all types of calories increased, with the exception of vegetables and dairy foods.
Turning to details, meats, eggs, and nuts comprised 465. While the leader for the first year experienced a notable decline to 455 in 1990, by 2010, it saw a modest increase of 15 units. Grains and added fats significantly rose throughout the period, by 195 and 230, respectively. Additionally, they dominated for approximately the last two decades. In 1970, sugar made up 400 units, then soared and reached 460 in the final year. Fruit showed an increase of 5 units every 20 years, from its initial 70 to 85 units.
Similarly, starting at 265, the consumption of dairy gradually decreased to 255 units. And vegetables showed an almost identical pattern of change, from 125 to 120.
