Concerns about consumer health in relation to COVID-19 have led to a rise in the popularity of healthier products, particularly among older adults who are anxious about their heart and digestive well-being. While there is a notable interest in foods that promote overall health, research indicates that food choices often do not align with this intention. A recent study from New York University revealed that the consumption of highly processed foods—characterized by high levels of refined carbohydrates and saturated fats, along with a lack of fiber—rose by 3.5 percentage points across all age demographics over the 18-year study period. Concurrently, the intake of whole foods declined. This increase in highly processed food consumption does not contribute positively to the rates of obesity or life expectancy in Americans, although the cognitive impacts may not become evident until later in life. The study also highlighted that older adults (aged 60 and above) saw the most significant rise in the consumption of ultra-processed foods. Research from Ohio State University indicated that a diet high in processed foods could lead to memory impairment within just four weeks.
Food manufacturers are becoming increasingly aware of the links between ultra-processed foods and health issues, prompting some to reformulate their products for a healthier profile. Brands are specifically catering to health-conscious consumers by incorporating omega-3 into their products, given its association with mental health benefits and improved learning abilities. For instance, Horizon Milk and Costco’s Kirkland brand enhance their omega-3 content with DHA, while omega-3-fortified eggs are commonly found in grocery stores. Nestlé has enriched its Juicy Juice with omega-3s, Pinnacle Foods offers an omega-3 fortified Smart Balance peanut butter, and Conagra’s Earth Balance features an omega-3 butter spread. However, despite the popularity of omega-3, many supplements are derived from fish and algae, which can impart a distinctly oceanic flavor to products.
In response to this, agricultural seed producer Nuseed, a subsidiary of Australia’s Nufarm, Ltd., is collaborating with ingredients giant ADM to crush its proprietary omega-3 canola, aiming to create a sustainable, land-based source of omega-3 that minimizes any fishy taste. Access to such a sustainable omega-3 source could enhance the appeal of these nutrients even further. Nevertheless, consumers need to exercise caution when considering the addition of DHA supplements, such as those found in Citracal Plus tablets, to processed foods to counteract the adverse health effects of processed food consumption. Research from Ohio State University indicates that even processed foods enriched with omega-3 can still pose risks of weight gain, heart disease, cancer, diabetes, and increased mortality. Ultimately, as the market evolves, the challenge will be to balance health benefits with the consumption of highly processed products.
