How Advice on Eating Habits has Changed Over the Years

The way we approach nutrition has totally changed over the years, and there is a huge amount of information out there to help us make educated decisions about what we consume. The more time passes, the more reliable advice on eating habits emerges. We’re here to delve into how this can help us make healthier choices today.

Which key areas of nutrition have experienced significant changes and developments over the years?

Fat intake

For several decades, low-fat diets were recommended as the best way to prevent heart disease and lose weight. However, more recent research has shown that not all fats are created equal and that healthy fats like those found in nuts, seeds, and olive oil, can actually be beneficial for our health.


The role of carbohydrates in the diet has been a source of controversy over the years. Initially, high-carb diets were recommended, but more recently, low-carb diets have gained popularity for weight loss and blood sugar control. However, the latest nutrition guidance emphasizes the importance of choosing high-quality, nutrient-dense carbohydrates, such as whole grains and fruits, rather than limiting carbs altogether.


In the past, cholesterol was believed to be a major contributor to heart disease, and foods high in cholesterol, such as eggs, were discouraged. However, more recent research has shown that dietary cholesterol has only a small impact on blood cholesterol levels and that other factors, such as the type and amount of fat in the diet, have a greater impact on heart health.

Added sugars 

In recent years, there has been increasing concern about the negative health effects of consuming too much added sugar. The latest nutrition guidance recommends limiting added sugars, which are often found in processed foods and drinks, to help reduce the risk of chronic diseases such as obesity, type 2 diabetes, and heart disease.

5 key trends in nutrition guidance in the 21st century:

  1. Increased focus on whole foods: There has been a growing emphasis on the importance of consuming whole, minimally processed foods rather than relying on highly processed, packaged foods. This has been driven by a recognition of the huge health benefits of a diet rich in fruit, veggies, whole grains, and lean proteins.
  1. Personalisation: Nutrition guidance has become increasingly more personalised in recent years, taking into account individual factors such as age, gender, weight, physical activity level, and medical conditions. This means that people are encouraged to develop an eating pattern that works best for their individual needs rather than following a one-size-fits-all approach. We’re all unique, so our nutrition should be too!
  1. Environmental sustainability and accountability: Nutrition guidance in the 21st century has also begun to take into account the impact of food systems on the environment. There is a growing recognition of the need for diets that are both healthy for individuals and sustainable for the planet. 
  1. Emphasis on nutrient-dense foods: While the focus on whole foods has remained important over the years, there has also been an increased emphasis on nutrient-dense foods, such as leafy greens, nuts, and seeds, which are high in vitamins, minerals, and other important nutrients.
  1. Understanding of the gut microbiome: In recent years, there has been a growing (and very interesting) body of research on the role of the gut microbiome in health and disease. This has led to a greater understanding of the importance of fermented foods, prebiotics, and probiotics in maintaining a healthy gut microbiome and overall health.
