Which of the following is a negative effect of high omega-6 consumption?

High omega-6 consumption is associated with increased inflammation in the body. Omega-6 fatty acids, particularly when consumed in excessive amounts relative to omega-3 fatty acids, can promote the production of pro-inflammatory compounds. This imbalance can contribute to various health issues, including chronic inflammatory conditions and heart disease.

In terms of the other options, they present benefits typically associated with healthier dietary choices rather than being influenced negatively by high omega-6 intake. Improved heart health, enhanced cognitive function, and reduced cholesterol levels are commonly linked with beneficial dietary patterns that include proper balances of omega-3s and omega-6s. In contrast, the overconsumption of omega-6s does not provide these advantages and can instead lead to detrimental health effects.
