Ultra-processed food in the context of "Froot Loops"

Convenience food (also called tertiary processed food) is food that is commercially prepared (often through processing) for ease of consumption, and is usually ready to eat without further preparation. It may also be easily portable, have a long shelf life, or offer a combination of such convenient traits. Convenience foods include ready-to-eat dry products, frozen food such as TV dinners, shelf-stable food, prepared mixes such as cake mix, and snack food. Food scientists now consider most of these products to be ultra-processed foods and link them to poor health outcomes.

Bread, cheese, salted food and other prepared foods have been sold for thousands of years, but these typically require a much lower level of industrial processing, as reflected in systems such as the Nova classification. Other types of food were developed with improvements in food technology. Types of convenience foods can vary by country and geographic region. Some convenience foods have received criticism due to concerns about nutritional content and how their packaging may increase solid waste in landfills. Various methods are used to reduce the unhealthy aspects of commercially produced food and fight childhood obesity.

A healthy diet is a diet that maintains or improves overall health. A healthful diet provides the body with essential nutrition: water, macronutrients such as protein, micronutrients such as vitamins, and adequate fibre and food energy.

A healthy diet may contain fruits, vegetables, and whole grains, and may include little to no ultra-processed foods or sweetened beverages. The requirements for a healthy diet can be met from a variety of plant-based and animal-based foods, although additional sources of vitamin B₁₂ are needed for those following a vegan diet. Various nutrition guides are published by medical and governmental institutions to educate individuals on what they should be eating to be healthy. Not only advertising may drive preferences towards unhealthy foods. To reverse this trend, consumers should be informed, motivated and empowered to choose healthy diets. Nutrition facts labels are also mandatory in some countries to allow consumers to choose between foods based on the components relevant to health.

Lifestyle medicine (LM) is a branch of medicine focused on preventive healthcare and self-care dealing with prevention, research, education, and treatment of disorders caused by lifestyle factors and preventable causes of death such as nutrition, physical inactivity, chronic stress, and self-destructive behaviors including the consumption of tobacco products and drug or alcohol abuse. The goal of LM is to improve individuals' health and wellbeing by applying the 6 pillars of lifestyle medicine (nutrition, regular physical activity, restorative sleep, stress management, avoidance of risky substances, and positive social connection) to prevent chronic conditions such as cardiovascular diseases, diabetes, metabolic syndrome and obesity.

Lifestyle medicine focuses on educating and motivating patients to improve the quality of their lives by changing personal habits and behaviors around the use of healthier diets which minimize ultra-processed foods such as a Mediterranean diet or whole food, plant-predominant dietary patterns. Poor lifestyle choices like dietary patterns, physical inactivity, tobacco use, alcohol addiction and dependence, drug addiction and dependence, as well as psychosocial factors, e.g. chronic stress and lack of social support and community, contribute to chronic disease. In the clinic, major barriers to lifestyle counseling are that physicians feel ill-prepared and are skeptical about their patients' receptivity. However, by encouraging healthy decisions, illnesses can be prevented or better managed in the long-term.

Junk food is a term used to describe food that is high in calories from macronutrients such as sugar and fat, and often also high in sodium, making it hyperpalatable, and low in dietary fiber, protein, or micronutrients such as vitamins and minerals. It is also known as high in fat, salt and sugar food (HFSS food). The term junk food is a pejorative dating back to the 1950s.

Precise definitions vary by purpose and over time. Some high-protein foods, like meat prepared with saturated fat, may be considered junk food. Fast food and fast-food restaurants are often equated with junk food, although fast foods cannot be categorically described as junk food. Candy, soft drinks, and highly processed foods such as certain breakfast cereals, are generally included in the junk food category; much of it is ultra-processed food.

Hyperpalatable food (HPF) combines high levels of fat, sugar, sodium, or carbohydrates (excluding dietary fiber) to trigger the brain's reward system, encouraging excessive eating. The concept of hyperpalatability is foundational to ultra-processed foods, which are usually engineered to have enjoyable qualities of sweetness, saltiness, or richness. Hyperpalatable foods can stimulate the release of metabolic, stress, and appetite hormones that play a role in cravings and may interfere with the body's ability to regulate appetite and satiety.

Almond milk is a plant-based milk substitute with a watery texture and nutty flavor manufactured from almonds, although some types or brands are flavored in imitation of cow's milk. It does not contain cholesterol or lactose and is low in saturated fat. Almond milk is often consumed by those who are lactose-intolerant and others, such as vegans, who do not consume dairy products.

Commercial almond milk comes in sweetened, unsweetened, vanilla and chocolate flavors, and is usually fortified with micronutrients as a processed food.
