Knowledge: a foundation for healthier choices
Knowledge helps us make sense of the world and the choices available to us. When it comes to health, having clear, reliable information can help people feel more confident about looking after themselves and seeking support when they need it.
Understanding health is more than knowing the facts
Health information is most useful when it is understandable, relevant and put into context. Advice about food, physical activity, sleep and wellbeing can support healthier habits, but there is no single approach that works for everyone. A person’s health is shaped by many factors, including their circumstances, environment, access to services and individual needs.
This is especially important when learning about obesity. It is a complex health issue, influenced by a range of biological, social, psychological and environmental factors. Reducing it to personal choices alone can overlook these influences and contribute to unfair judgement. A more informed understanding encourages thoughtful conversations and compassionate support.
Finding information you can trust
Health claims can be found everywhere, from social media posts to advertisements and personal stories. Before acting on advice, consider where it comes from, whether it is supported by credible evidence and whether it is appropriate for your own circumstances. Be cautious of claims that promise quick results or present one product, diet or treatment as a solution for everyone.
For personal health concerns, a GP or another qualified healthcare professional can help explain the options available. They can take individual circumstances into account and help identify support that is safe and suitable.
Knowledge can encourage positive change
Learning does not need to lead to dramatic changes all at once. Understanding a topic can help people ask questions, recognise when they need support and consider manageable steps towards better wellbeing. It can also help families, schools, workplaces and communities create environments where healthier choices are easier to make.
Knowledge is not about blame or perfection. It is a tool for understanding, making informed decisions and treating ourselves and others with respect. By sharing accurate information and staying open to learning, we can build a more supportive and health-conscious society.

What is knowledge?
Knowledge is the understanding, information and skills gained through learning, experience and observation. It helps us make sense of the world, form informed opinions and decide how to act. Knowledge can come from many sources, including education, research, practical experience and conversations with others, and it continues to develop as we learn and encounter new ideas.
How is knowledge different from information?
Information consists of facts, figures or details, while knowledge is the understanding we develop by interpreting and connecting that information. For example, reading guidance about healthy eating gives you information; understanding how it applies to your needs and using it to make informed choices is knowledge.
What are the main types of knowledge?
The main types of knowledge are often described as explicit, implicit and tacit. Explicit knowledge is recorded and easy to share, such as information in books, guides or databases. Implicit knowledge is practical understanding gained by applying information, while tacit knowledge comes from personal experience and can be difficult to put into words—for example, knowing how to respond to a situation through judgement developed over time. These types often work together: facts provide a foundation, while practice and experience help people use them effectively.
How do people acquire knowledge?
People acquire knowledge in many ways, including through education, reading, observation, discussion and hands-on experience. Asking questions, reflecting on what has been learned and checking information against reliable sources can deepen understanding. Knowledge also develops over time as people encounter new evidence, consider different perspectives and connect new ideas with what they already know.
Why is knowledge important?
Knowledge is important because it helps us understand the world, make informed decisions and respond to challenges with greater confidence. It can guide everyday choices, support personal growth and help us recognise when to seek advice or support. When knowledge is accurate and shared accessibly, it can also reduce misunderstanding, encourage empathy and help communities make positive changes.
How can knowledge be measured or assessed?
Knowledge can be assessed in several ways, depending on what someone needs to understand or do. Tests and quizzes can check recall and comprehension, while discussions, written work and practical tasks can show how well a person can explain, apply and evaluate information. Assessment may also consider problem-solving, the ability to make connections and whether someone can distinguish reliable evidence from misinformation. No single measure captures everything a person knows, so using a range of methods usually gives a fuller picture.
Can knowledge change over time?
Yes, knowledge can change over time as new evidence emerges, better research methods become available and our understanding develops. Ideas once thought to be certain may be revised or replaced, so it is helpful to consider when information was published and whether it comes from a reliable, up-to-date source. Staying open to new evidence allows us to learn and make better-informed decisions.
