the value of good health

  Introduction Good health is often considered one of life's greatest assets. It is not merely the absence of diseases but a state of complete physical, mental, and social well-being. In today's fast-paced world, maintaining good health is paramount to leading a fulfilling and productive life. This comprehensive guide explores the various aspects and benefits of good health, providing valuable insights into its value and the steps you can take to achieve and maintain it. Physical Health Regular Exercise: Engaging in regular physical activity is essential for good health . Exercise strengthens muscles, improves cardiovascular health, enhances flexibility, and boosts overall energy levels. Aim for at least 150 minutes of restrained-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise per week, along with muscle-strengthening activities on two or more days a week. Balanced Nutrition: A well-balanced diet provides you...

energy and nutrient density of food

 

Energy and nutrient density of food

The energy and nutrient density of food is used to assess food groups in the context of a healthy diet or weight reduction. The background: The goal should be the highest possible nutrient and low energy content in our food. However, the terms are often misunderstood and misused. As a result, the interpretation and practical relevance are sometimes misleading. To make matters worse: Not every food with a high-calorie content is unsuitable per se, as it can also contain numerous essential nutrients. Conversely, it makes little sense to eat low-calorie foods that cannot meet the nutritional needs.

Energy density: assessment of energy content

The energy density describes the energy content in kilocalories per gram consumed. Foods with an energy content below 150 kcal per 100 g are generally considered low in energy. Contents between 150 and 250 kcal are energy moderate. Therefore, food with more than 250 kcal per 100 g is deemed high in power.

The energy density of food can be determined and categorized relatively easily. An interactive table showing the energy density of food can be found on page 2 of this article.

Nutrient density: Assessment of the nutrient content

The nutrient density should enable qualitative statements to be made about food choice. Several definitions are circulating in the specialist books. They all have a mutual relationship between the nutrient content and the respective food's energy content.

Since our body needs the various nutrients in entirely different amounts, it isn't easy to aggregate the nutrient content for all nutrients. Strictly speaking, to make foods comparable with one another, a nutrient density to be calculated always relates to a single nutrient.

With this definition, there are already some difficulties. If a high nutrient density per se is desirable and this always relates to a single nutrient, foods rich in sugar and high in salt are also recommended since sugar and salt are also nutrients (carbohydrates and sodium). Here, nutrients would have to be differentiated depending on the consumption recommendation.

A general classification of all foods according to nutrient density is therefore tricky. That also makes it unsuitable for practice.

Therefore, in some specialist books, nutrient density relates in the narrower sense to the average micronutrient content such as vitamins and minerals.

It would then be understandable that fresh vegetables or fresh herbs should be classified as nutrient-dense due to their small calorie and high micronutrient content, especially minerals and vitamins. On the other hand, chips, pizza, or croissants score poorly due to their very high energy content with manageable minerals and vitamins and low nutrient density.

If, on the other hand, the nutrient density relates to the content of essential nutrients, the following food classification could be formulated:

high nutrient density

Foods with a low energy content and a high nutritional content

It would then be understandable that fresh vegetables or fresh herbs should be classified as nutrient-dense due to their low calorie and height micronutrient content, especially minerals and vitamins.

If, on the other hand, the nutrient density relates to the content of essential nutrients, the following food classification could be formulated:

high nutrient density

Foods with a low energy content and a high nutritional content

moderate to high nutrient density

Medium-energy, high-nutrient foods.

low nutrient density

Foods with a high energy content and a low nutritional content

Medium-energy, high-nutrient foods

low nutrient density

Foods with a high energy content and a low nutritional content

coffee and caffeine effects on health

Coffee or caffeine has numerous effects on the human body. The following article shows the physiological effects, effects depending on the phase of life or lifestyle, interactions with nutrients and drugs, and observed results in various diseases. Physiological effects of the alkaloid caffeine General health As in most cases, whether coffee has a positive or negative effect on health depends on the dose. In excessively high doses, the alkaloid caffeine can lead to fear, restlessness, nervousness, irritability, or even insomnia. Scientific studies indicate a threshold of around 1.2 g per day. In the long term, consuming 2-5 cups of coffee a day can positively affect mortality. This was slightly reduced in studies. The combination of caffeine and alcohol has a negative effect. Cardiovascular disorders, as well as psychological and neurological complications, are documented here. Cardiovascular system Caffeine speeds up the heart, metabolism, and breathing. Blood pressure and...

what is the new definition of health?

The World Health Organization (WHO) has redefined health as a state of complete physical, mental and social well-being and not merely the absenteeism of disease or infirmity. This definition was adopted in 1948 and has been widely accepted by the global health community. The new definition of health reflects the growing understanding that health is not just about the absence of disease, but also about the attendance of positive factors that contribute to well-being. These factors include social and economic factors, as well as individual factors such as mental health and physical activity. The new definition of health has important implications for public health policy. It suggests that the focus of public health should be on promoting positive health, not just preventing disease. This means investing in factors that contribute to well-being, such as education, housing, and employment. The new definition of health is also important for individuals. It suggests that we should thin...
