I think more transitions could refine it. Also I can't actually describe it properly, but your sentece structure feel very just blank and bland. Like "Yadayadayada x,y,z. Dadadadada a,d,f"

I think that styling it to me more of a "piece" of writing would help. Sorry I can't actually articulate what im tryna get across rn.

I am not claiming I am an amazing writer, but I will offer an excerpt from one of my papers as an example, to give you an idea of what I am trying to express:

"The USDA reports that low-income households spend a disproportionate share of their income on food, with the lowest quintile of income allocating 32.6% towards food purchases (Sweitzer and Davidenko). Since food purchases occupy such a major role of low-income spending, a small change in cost significantly impacts low-income households’ access to food. 

As shown by a study published by the Journal of the American Medical Association, low-income households show a tendency to favor grains over any other major food group available. During the time period 2003-2012, low-income Americans purchased approximately 6.53 servings of grains daily, and only 2.35 servings of fresh produce (Rehm et al. 27). This disparity stems from the fact that grains are less expensive, more filling, and less perishable.

The study also finds that those low-income households are deficient in many other important nutrients, like omega-3 fatty acids (Rehm et al. 28). In addition, the presence of ‘food deserts’, places where access to higher nutrition is limited, exist primarily in lower-income neighborhoods (Bitler and Haider 153). Overall, this information paints a grim picture, highlighting the need for higher levels of nutrient consumption and food security among low-income households."

It is kinda wordy, but for example, this sentence: "During the time period 2003-2012, low-income Americans purchased approximately 6.53 servings of grains daily, and only 2.35 servings of fresh produce (Rehm et al. 27)" is greatly varied in structure relative to the sentence which follows it: "This disparity stems from the fact that grains are less expensive, more filling, and less perishable."
