Vitamin A, vitamin D, vitamin E, zinc, omega-3 fatty acids, and omega-6 fatty acids are among the most-studied nutrients active in the immune response, though many other nutrients play integral parts in the optimal function of the immune system. Prolonged inflammation contributes to the progression of many chronic diseases, such as types 1 and 2 diabetes mellitus, cardiovascular disease, Alzheimer’s, psoriasis, lupus, and more. Modifiable lifestyle factors including diet, smoking, and exercise have profound impacts on these levels of inflammation. While acute inflammation is necessary for healing, chronic, low levels of inflammation appear to be major players in chronic disease etiology. Immune dysregulation and oxidative stress are closely related to inflammation in the body, with common etiology and positive feedback loops, compounding the detrimental impacts. For many, this inflammation may go undetected for years, leading it to be termed the “silent killer” by scientific and media reports. Regardless of a symptom manifestation, chronic inflammation poses a damaging impact, increasing risk of chronic disease and mortality. Western lifestyle behaviors such as poor diet, inactivity, and smoking are often underlying root causes of this inflammation. Relationships are a major part of an individual’s health and well-being. Often, a community or intimate relationships can have a direct influence on diet choices. Positive relationships can allow for easier implementation of nutritional interventions, particularly in the case of caregiver support. Spouses committed to health changes can promote reciprocal behavior in their partners; stressed relationships can also prevent adequate nourishment and be a burden to one’s health. Even beyond diet choices, induced stress, potentially from a relational cause, can alter digestive, lipid, glycemic, and inflammatory responses to meals. Physical activity is an integral part of an individual’s nutritional status. Physical activity has a long-established role in body composition and nutrient metabolism. One of the most-studied nutrients involved in mitochondrial function is coenzyme Q10 (CoQ10). CoQ10 is required for ATP production via the electron transport chain and also has a powerful antioxidant function. Deficiencies in CoQ10 caused by metabolic disorders or statin medications can result in mitochondrial dysfunction and reactive oxygen species.
