Unpacking the science of nutrition: What you need to know
The science of nutrition is constantly evolving, and it can be tough to keep up with the latest findings. But understanding the basics of good nutrition is essential to maintaining a healthy lifestyle. Here's a quick rundown of what you need to know about nutrition and your health.
Nutrition
Nutrition is the science that studies the relationship between diet and health. It is important to know what food contains and how it affects our bodies.
Nutrients are substances in food that our bodies need in order to grow and function properly. Nutrition also looks at how our diet affects our overall health and well-being.
How does nutrition affect my health?
The food we eat every day provides our bodies with the nutrients they need to function properly.
These nutrients are essential for good health and can help to protect us from chronic diseases such as heart disease, stroke, and cancer.
Good nutrition is also important for healthy growth and development in kids and teens. It can help to prevent obesity and other chronic health problems later in life.
What are the different types of nutrients?
There are seven main types of nutrients: carbohydrates, fats, proteins, vitamins, minerals, dietary fiber, and water.
Carbohydrates, fats, and proteins are macronutrients, which means that we need them in large amounts to maintain our health. Vitamins and minerals are micronutrients, which means that we only need them in small amounts.
Dietary fiber and water are also important for good health, but they are not classified as nutrients. Water is essential for all life and makes up a large part of our bodies.
Carbohydrates
Carbohydrates are one of the main types of nutrients. They are the body's main source of energy and are found in a wide variety of foods, including bread, cereals, fruits, vegetables, and milk products.
Fats
Fats are another type of nutrient. They provide the body with energy and help to absorb vitamins. Fats are found in oils, butter, margarine, meat, poultry, fish, nuts, and seeds.
Proteins
Proteins are essential for the growth and repair of all tissues in the body. They are found in meat, poultry, fish, eggs, milk products, beans, and legumes.
Vitamins
Vitamins are essential nutrients that the body needs in small amounts to function properly. They are found in a wide variety of foods, including fruits, vegetables, meat, eggs, milk products, and grains.
Minerals
Minerals are another type of essential nutrient. They are found in a variety of foods, including meats, poultry, fish, eggs, milk products, nuts, and seeds.
Water
Water is essential for all life. It makes up about 60 per cent of our bodies and is found in a variety of foods and beverages.
Recommended daily intake of nutrients
The recommended daily intake (RDI) of nutrients is the amount of each nutrient that most people need to meet their basic needs.
The RDIs are based on the latest scientific evidence and are updated every few years. They are different for each nutrient and depend on a person's age, sex, and stage of life.
For example, pregnant women need more iron than other adults, and young children need more vitamin C than adults.
Most people should be able to get all the nutrients they need by eating a healthy, balanced diet. However, some people may need to take supplements if they are not able to get enough of certain nutrients from their diet.
The average RDI for an average human is as follows:
- Carbohydrates: 300 grams
- Fats: 70 grams
- Proteins: 56 grams
- Vitamins: A, B1 (thiamine), B2 (riboflavin), B3 (niacin), B6, B12, C, D, E, and K
- Minerals: Calcium, phosphorus, iron, magnesium, zinc, copper, iodine, selenium, and molybdenum
- Water: 2.7 liters (for men), and 2.2 liters (for women) per day.
How do I know if I'm getting enough nutrients?
The best way to make sure you're getting all the nutrients you need is to eat a variety of healthy foods from all the food groups. This includes fruits, vegetables, whole grains, lean protein, low-fat dairy, and healthy fats.
It's also important to limit or avoid processed foods, sugary drinks, and excessive amounts of saturated and unhealthy fats.
If you're unsure about whether you're getting enough nutrients, you can talk to your healthcare provider or a registered dietitian. They can help you determine if you need to take supplements or make changes to your diet.
What is the difference between food and nutrition?
The term food refers to anything that people eat or drink to satisfy their hunger or thirst.
Nutrition, on the other hand, is the science that deals with the nutrients in food and how they are used by the body. In other words, nutrition is the study of how food affects our health.
