A Healthy Diet Contains Life Sustaining Nutrients
Maintaining a healthy diet is the practice of making choices about what to eat with the intent of improving or maintaining good health. It involves consuming the necessary nutrients by eating the appropriate amounts from all of the food groups, including an adequate amount of water.
Since human nutrition is complex a proper diet may vary widely subject to an individual's genetic makeup, environment, and health.
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 on what nutrients to ingest.
Make sure that you eat five different types of fruit and vegetables every day. Every day also make sure that you eat at least one thing from each of the different food groups: Carbohydrates, Fruits and vegetables, Protein, Dairy, and Fats.
Remember to eat more fruit and vegetables and less fats
Too much salt gives you high blood pressure and a high fat diet will give you hard and narrow arteries that could lead to heart attacks and strokes, possibly even death.
Fruit and vegetables contain antioxidants which will keep you healthy as long as you team them up with regular daily exercise. Your efforts to eat healthy will go to waste if you do not take part in regular daily exercise.
Fiber in your diet will keep your digestive system going strong.
Some foods like processed 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.
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.
Generally, a healthy diet is said to include:
- Sufficient calories to maintain a person's metabolic and activity needs, but not so excessive as to result in fat storage greater than roughly 30% of body mass.
- Sufficient quantities of fat, including monounsaturated fat, polyunsaturated fat and saturated fat, with a balance of omega-6 and long-chain omega-3 lipids.
- Maintenance of a good ratio between carbohydrates and lipids (4:): four grams of carbohydrates to one gram lipids.
- Avoidance of saturated fat (although the "evidence" for this claim is forever in debate after the testimony of results provided by the Framingham Heart Study of 1948-1998).
- Avoidance of trans fat.
- Sufficient essential amino acids ("complete protein") to provide cellular replenishment and transport proteins.
- Essential micronutrients such as vitamins and certain minerals.
- Avoiding directly poisonous (e.g. heavy metals) and carcinogenic (e.g. benzene) substances.
- Avoiding foods contaminated by human pathogens (e.g.e. coli, tapeworm eggs).
- Avoiding chronic high doses of certain foods that are benign or beneficial in small or occasional doses, such as; foods or substances with direct toxic properties at high chronic doses (e.g. ethyl alcohol) or foods that may interfere at high doses with other body processes (e.g. refined table salt).
A healthy diet is a well rounded diet composed of all the food groups in the appropriate proportions allowing for the proper amount of nutrients for our bodily functions at the cellular level.
