Healthy diet in the context of "Omega-6 fatty acid"

The treatment and management of COVID-19 combines both supportive care, which includes treatment to relieve symptoms, fluid therapy, oxygen support as needed, and a growing list of approved medications. Highly effective vaccines have reduced mortality related to SARS-CoV-2; for those awaiting vaccination, as well as for the estimated millions of immunocompromised persons who are unlikely to respond robustly to vaccination, treatment remains important. Some people may experience persistent symptoms or disability after recovery from the infection, known as long COVID, but there is still limited information on the best management and rehabilitation for this condition.

Most cases of COVID-19 are mild. In these, supportive care includes medication such as paracetamol or NSAIDs to relieve symptoms (fever, body aches, cough), proper intake of fluids, rest, and nasal breathing. Good personal hygiene and a healthy diet are also recommended. As of April 2020 the U.S. Centers for Disease Control and Prevention (CDC) recommended that those who suspect they are carrying the virus isolate themselves at home and wear a face mask. As of November 2020 use of the glucocorticoid dexamethasone had been strongly recommended in those severe cases treated in hospital with low oxygen levels, to reduce the risk of death. Noninvasive ventilation and, ultimately, admission to an intensive care unit for mechanical ventilation may be required to support breathing. Extracorporeal membrane oxygenation (ECMO) has been used to address respiratory failure, but its benefits are still under consideration. Some of the cases of severe disease course are caused by systemic hyper-inflammation, the so-called cytokine storm.

A sustainable food system is a type of food system that provides healthy food to people and creates sustainable environmental, economic, and social systems that surround food. Sustainable food systems start with the development of sustainable agricultural practices, development of more sustainable food distribution systems, creation of sustainable diets, and reduction of food waste throughout the system. Sustainable food systems have been argued to be central to many or all 17 Sustainable Development Goals.

Moving to sustainable food systems, including via shifting consumption to sustainable diets, is an important component of addressing the causes of climate change and adapting to it. A 2020 review conducted for the European Union found that up to 37% of global greenhouse gas emissions could be attributed to the food system, including crop and livestock production, transportation, changing land use (including deforestation), and food loss and waste. A different, more recent study in 2023 aimed to estimate the land footprint associated with food loss worldwide concluded an average of 69 million hectares per year.Reduction of meat production, which accounts for ~60% of greenhouse gas emissions and ~75% of agriculturally used land, is one major component of this change.

A sugary drink tax, soda tax, or sweetened beverage tax (SBT) is a tax or surcharge (food-related fiscal policy) designed to reduce consumption of sweetened beverages by making them more expensive to purchase. Drinks covered under a soda tax often include carbonated soft drinks, sports drinks and energy drinks. Fruit juices without added sugar are usually excluded, despite similar sugar content, though there is some debate on including them.

This policy intervention is an effort to decrease obesity and the health impacts related to being overweight. The tax is a matter of public debate in many countries and beverage producers like Coca-Cola often oppose it. Advocates such as national medical associations and the World Health Organization promote the tax as an example of a Pigouvian tax, aimed to discourage unhealthy diets and offset the growing economic costs of obesity.

A health food store (or health food shop) is a type of grocery store that primarily sells healthful foods, organic foods, local produce, and often nutritional supplements. Health food stores typically offer a wider or more specialized selection of foods than conventional grocery stores for their customers, for example people with special dietary needs, such as people who are allergic to the gluten in wheat or some other substance, and for people who observe vegetarian, vegan, raw food, organic, or other alternative diets.

A whole grain is a grain of any cereal and pseudocereal that contains the endosperm, germ, and bran, in contrast to refined grains, which retain only the endosperm.

As part of a general healthy diet, consumption of whole grains is associated with lower risk of several diseases. Whole grains are a source of carbohydrates, multiple nutrients and dietary fiber.
