Natural and Organic Food

From a psychological perspective, a new healthy diet may be difficult to achieve for a person with poor eating habits. This may be due to tastes acquired in early adolescence and preferences for fatty foods. It may be easier for such a person to transition to a healthy diet if treats such as chocolate are allowed; sweets may act as mood stabilizers, which could help reinforce correct nutrient intake.

It is known that the experiences we have in childhood relating to consumption of food affect our perspective on food consumption in later life. From this, we are able to determine ourselves our limits of how much we will eat, as well as foods we will not eat – which can develop into eating disorders, such as anorexia or bulimia nervosa. This is also true with how we perceive the sizes of the meals or amounts of food we consume daily; people have different interpretations of small and large meals based on upbringing.

While plants, vegetables, and fruits are known to help reduce the incidence of chronic disease, the benefits on health posed by plant-based foods, as well as the percentage of which a diet needs to be plant based in order to have health benefits is unknown. Nevertheless, plant-based food diets in society and between nutritionist circles are linked to health and longevity, as well as contributing to lowering cholesterol, weight loss, and in some cases, stress reduction.

Indeed, ideas of what counts as “healthy eating” have varied in different times and places, according to scientific advances in the field of nutrition, cultural fashions, religious proscriptions, or personal considerations.

In specific individuals, ingesting foods containing natural allergens (e.g. peanuts, shellfood) or drug-induced triggers (e.g. tyramine for a person taking an MAO inhibitor) may be life-threatening.

Some foods have low nutritional value, and if consumed on a regular basis will contribute to the decline of human health. This has been demonstrated by various epidemiological studies that have determined that foods such as processed and fast foods are linked to diabetes and various heart problems.

When improperly cut or prepared, a small number of foods (such as fugu) can result in death.

The ingredient usually cited as being most crucial to good health, water, has even been known to result in death when consumed in extraordinary quantities.

Although a healthy diet is based upon nutrition, people eat foods and not nutrients; as few people know which foods supply which nutrients, allowing people to self-regulate their diets means that they run the obvious risk of deficiency. Due to past difficulties of educating people about nutrient intake, governments have opted to counsel on what foods to eat rather than on what nutrients to ingest.

Most states set guidelines for a healthy diet — these usually vary slightly from country to country based upon demographics. These guidelines do however usually share the same recommendations of eating less fried or fatty foods to reduce cholesterol. Many guidelines suggest replacing certain foods with healthier alternatives that supply an abundance of nutrients, for instance using legumes or beans within a salad or pasta.

As BMI and weight changes from person to person, the general Reference Nutrient Intakes (RNI) set by governmental institutions may be somewhat lacking for some people, despite the fact that the RNI is generally calculated as higher than the average nutrient intake. It is even thought that some people may have needs above that of the RNI, meaning even if a person achieved nutrient intake, they would still not be fulfilling the RNI. The only real way to know the RNI for many people is to implicitly monitor the intake of nutrients and amount of exercise.

Generally, a healthy diet will include:

1. Sufficient calories to maintain a person’s metabolic and activity needs, but not so excessive as to result in fat storage greater than roughly 12% of body mass;

2. Sufficient quantities of fat, including monounsaturated fat, polyunsaturated fat and saturated fat, with a balance of omega-6 and long-chain omega-3 lipids;

3. Avoidance of trans fat.

4. Sufficient essential amino acids (“complete protein”) to provide cellular replenishment and transport proteins;

5. Essential micronutrients such as vitamins and certain minerals.

6. Avoiding directly poisonous (e.g. heavy metals) and carcinogenic (e.g. benzene) substances;

7. Avoiding foods contaminated by human pathogens (e.g. e. coli, tapeworm eggs);

8. Avoiding chronic high doses of certain foods that are benign or beneficial in small or occasional doses, such as

* foods or substances with directly toxic properties at high chronic doses (e.g. ethyl alcohol);
* foods that may interfere at high doses with other body processes (e.g. table salt);
* foods that may burden or exhaust normal functions (e.g. refined carbohydrates without adequate dietary fibre).

Achieving a healthy diet is popularly misperceived as being attainable by eating ‘healthy foods’. Many people[attribution needed] falsely believe that there are ‘good’ and ‘bad’ foods; they develop bad diets because they think that abundant eating of foods they consider ‘healthy’ will create a healthy diet. However, this is far from the truth.

The consumption of nothing but substances that are deemed healthy, such as an “all-grain diet” or a diet consisting only of pasta or other health-foods, would most likely result in deficiencies because important nutrients (like protein-based foods) would be missed. Foods such as grains, fish, corn, etc. are healthy when consumed with a balanced diet, because in combination they supply us with all of the required nutrients. The most important aspect of any diet is maintaining a healthy intake and balance of foods.

The balance of micronutrients gained from meat, vegetables, and other foods is what makes diets healthy, not only consuming ‘healthy’ foods. For instance, milk, cheese, and other dairy products are known to have a relatively high fat content. Removing such dairy products from a diet may lower fat ingestion, but it will also negatively affect the intake of calcium and riboflavin that such foods offer.

Maintaining a healthy diet is the practice of making choices about what to eat with the intent of improving or maintaining good health. Usually this involves consuming necessary nutrients by eating the appropriate amounts from all of the food groups. Since human nutrition is complex a healthy diet may vary widely subject to an individual’s genetic makeup, environment, and health. For around 20% of the planet’s population, lack of food and malnutrition are the main impediments to healthy eating.
