Nutrients - Importance and Health benefits


Nutrients are essential chemicals that our bodies need to function properly. We get these nutrients from eating a balanced diet. There are six main types of nutrients that are important for our health: carbohydrates, fats, proteins, vitamins, minerals, and water.

1. Carbohydrates, fats, and proteins: These are called macronutrients. They provide energy for our bodies.

2. Water: We need a lot of it, but it doesn't provide energy.

3. Vitamins and minerals: These are called micronutrients. They help with various processes in our bodies but don't provide energy.

Vitamins can be either water-soluble or fat-soluble:

  1. Water-soluble vitamins: These include vitamins B1, B2, B3, B5, B6, B7, B9, B12, and C.
  2. Fat-soluble vitamins: These include vitamins A, D, E, and K.

Minerals can be divided into two groups:

  1. Macrominerals: We need these in larger amounts. They include calcium, phosphorus, magnesium, sodium, potassium, and chloride.
  2. Microminerals: We need these in smaller amounts. They include iron, copper, zinc, selenium, and iodine. Sodium, potassium, and chloride are also known as electrolytes, which help with fluid balance in our bodies.

The biochemical aspects of these nutrients involve understanding their basic properties, how they function at the cellular and molecular levels, how they can be tested in the body, and their importance in clinical settings.

Importance of nutrition

Nutrients and their by-products do more than just build cellular structures and provide energy. They also directly influence how proteins work, act as powerful signaling molecules, and can turn genes on or off. Keeping a balance of nutrients in our cells is crucial for staying healthy and avoiding diseases caused by too few or too many nutrients. Both not getting enough nutrients (undernutrition) and getting too many (over-nutrition) disturb this balance and cause cellular stress. To cope, cells activate mechanisms like the unfolded protein response to manage the stress.

Traditionally, nutrients have been seen as just food for growth and energy. However, it is clear now that they also play active roles in facilitating, regulating, and coordinating many cellular processes. So, Eating foods that are low in calories but rich in various nutrients is a smart way to reduce stress on your cells and keep them healthy.

Effects of nutrition on health

Good nutrition relies on the entire food supply, including plant and animal foods and their different parts. These foods are essential for nourishing people. Nutrition is important not just for the growth and development of humans and animals, but also for preventing and treating diseases. It is key to maintaining good health and proper body function. Therefore, nutrition is a crucial part of solving many of the world's social, environmental, and economic problems.

Nutrition plays a crucial role in our health, affecting conditions like heart disease, cancer, and diabetes. To reduce the risk of these diseases, it's advised to cut down on fats, be mindful of calories, and eat more fruits and vegetables. These changes also help manage weight, which is important as excess weight can worsen other health issues. Calcium is also important, especially in younger years, as it helps build strong bones and can prevent osteoporosis later in life. Studies show that following these guidelines can greatly improve our health.

Maintaining good nutrition is essential for keeping our bodies working properly and preventing problems caused by various factors. When we don't get enough of the right nutrients, our bodies can struggle to function well. On the other hand, eating the recommended amounts of nutrients helps our bodies work better. More and more studies show that what we eat affects not only our physical health and body shape but also our mood and mental well-being.

Food, nutrition, diet, and health

Nutrition and food science have improved our ability to create a plentiful, nutritious, and safe food supply. A healthy diet should include all necessary nutrients and enough calories to balance energy use, support growth, and maintain health throughout life.

Different life stages have specific nutritional needs. Infants, children, and teenagers need nutrients for growth and brain development. During pregnancy, both the mother and baby have special nutritional requirements. Adult nutrition focuses on maintaining tissues, meeting energy and nutrient needs, and preventing diseases. As the number of elderly people grows, their nutrition needs must be met to reduce disease risk and ensure a good quality of life.

Common nutrient deficiencies

Nutrients are vital for good health, and nutrient deficiency happens when the body doesn’t get enough essential vitamins and other nutrients. This can upset the balance needed for our well-being and normal body functions. Here’s what can happen if one don’t get enough nutrients:

  • Feeling tired and weak
  • Developing anemia
  • Having a weaker immune system
  • Facing bone health problems
  • Experiencing hormonal imbalances
  • Having a higher risk of chronic diseases

Common nutrient deficiencies include -

  1. Vitamin D deficiency
  2. Iron deficiency
  3. Calcium deficiency
  4. Vitamin B12 deficiency
  5. Vitamin A deficiency
  6. Magnesium deficiency

Not getting enough nutrients can harm our health, but eating a balanced diet with lots of nutrient-rich foods can usually prevent this. If we have symptoms or risks of nutrient deficiencies, it's best to get tested early so we can find out the problem and do something about it. To stay healthy, it's important to eat a variety of foods every day that are rich in nutrients. This helps prevent nutrient deficiencies and keeps our body functioning well.

Steatotic liver disease - Causes & Treatment

Image
  Steatotic liver disease refers to disorders characterized by abnormal lipid accumulation in the liver (liver or hepatic steatosis). Steatotic liver disease includes what was previously known as non-alcoholic fatty liver disease (NAFLD), but is now referred to as metabolic dysfunction-associated steatotic liver disease. Steatotic liver disease also includes alcohol-related liver disease (ALD), MetALD, a new categorization for the overlap between MASLD and ALD, as well as unusual causes of liver steatosis. Steatotic liver disease affects around 30% of the global population and is mostly caused by obesity, type 2 diabetes, and alcohol consumption; however, only a small fraction of those with steatotic liver disease develop cirrhosis. The presence and advancement of liver fibrosis caused by hepatic inflammation is the most reliable predictor of liver death across the whole range of steatotic liver disorders. A combination of recent advances in widely available biomarkers ...

What Doctors Won’t Tell Us About Nutrition: A Simple and Honest Look at Food and Health

Image
  We've been given a lot of food advice throughout our lives, most of which we've never questioned. We've been told that meat provides protein, and eggs are a complete health food. But what if the majority of this information was incorrect or incomplete? In this article, I'll address some of the misunderstandings that are providing us incorrect information about our plant-based diet. The Conventional Medical Paradigm Let's start with a shocking fact: most medical practitioners have little nutrition training. In medical colleges, only a few hours—sometimes a single lecture—are dedicated to what should be a key component of illness prevention. Most modern medicine focuses on treating symptoms rather than determining the causes of sickness. We are given prescriptions, scheduled for procedures, or urged to monitor our conditions—but no one actually helps us prevent or reverse them through lifestyle and food. This leaves a space that we must fill by taking ow...

Fibre

Image
  Dietary Fibres Dietary fiber is the amount of food that comes from plant cells and is indigestible and unabsorbed to humans due to the lack of basic enzymes. Chemically, it is a polysaccharide. Fibre is present in grains, fruits, and vegetables, boosts general wellbeing, aids in preventing constipation, and improves digestive health. It contributes to a balanced and healthful eating pattern by giving the diet more volume without adding calories. Types of Fibre Fibre is classified into two types: Soluble fibre Insoluble fibre Soluble Fibre Soluble fibre is a type of dietary fiber that dissolves in water and forms a gel-like substance in the digestive tract. Unlike insoluble fibre, which remains unchanged as it passes through the digestive system, soluble fibre undergoes a transformation, creating a viscous solution that plays a crucial role in various aspects of human health. This type of fibre is found in foods such as oats, barley, beans, fruits, and vege...
