Here is the page from which the chart is from https://www.ers.usda.gov/data-products/chart-gallery/gallery...

The data in the chart is sweetener "availability" and not really consumption, though it can be assumed that if less is available per capita, then less is consumed as well (per capita). But, this data doesn't explains the increase in obesity since 1970. this might be because of data being an average. Stats like p90 sugar consumption might show a better correlation with obesity rates and hence may be more meaningful than per capita sweetener availability.
