Salt, Sodium and Potassium

Salt, Sodium and Potassium
Salt sodium and potassium are essential minerals for maintaining fluid balance, nerve and muscle function, and controlling blood pressure. An excessive intake of sodium and inadequate intake of potassium can lead to an increased risk of heart disease and stroke.
Sodium is commonly found in the form of table salt, however, the majority of sodium consumed is derived from processed foods, such as packaged food and restaurant meals. The recommended daily consumption of salt is less than 5 grams, and the recommended daily intake of potassium should be 3.5-5 grams.

In order to maintain a healthy diet, it is important to monitor your salt, sodium and potassium intake. Many processed foods, such as canned soups, frozen dinners, and processed meats, contain high levels of sodium. Eating fresh fruits and vegetables, and reducing consumption of processed foods and sauces, such as soy sauce, can help keep sodium levels in check.

Additionally, increasing intake of potassium-rich foods, such as leafy greens, nuts, and legumes, can help reduce the risk of heart disease.


Free sugars refer to syrups and sweeteners that are added by manufacturers to certain products. These include sodas, yogurt, and cereals. Individuals may also add sugar to coffee and other items. It is suggested that the daily intake of free sugars should not exceed 10% of total energy intake.

When discussing sugars, it is important to differentiate between free sugars and naturally occurring sugars. Free sugars are those added to processed foods, such as sweetened drinks, cereal bars, and yogurts, as well as those added to food and beverages by individuals, such as sugar in coffee and tea. On the other hand, naturally occurring sugars are found in fruits, vegetables, and milk products.

It is recommended that free sugar intake should not exceed 10% of total energy intake. Consuming too much free sugar can increase the risk of developing various health problems, such as dental caries, unhealthy weight gain, and cardiovascular diseases. To lower free sugar intake, it is advised to drink water rather than sugary drinks, replace sweet snacks with fresh fruits, and to read food labels to identify added sugars.

Additionally, it is important to be aware of the amount of sugar in foods and drinks, such as soft drinks, fruit juice, grain foods, sugary drinks, and processed foods. Eating too much sugar can lead to high blood pressure, an increased risk of obesity, and high blood sugar.

Promoting Healthy Diet

Promoting Healthy Diets
Advocating for healthy diets is essential for maintaining physical and mental well-being. According to the World Health Organization (WHO), healthy diets can reduce the risk of chronic conditions, including obesity, heart disease, diabetes, and some forms of cancer. In order to promote healthy diets, it is important to understand the elements that influence dietary patterns, such as income, food prices, and cultural traditions.

Governments have a role to play in promoting a healthy food environment. This includes providing information on healthy eating, setting dietary guidelines, implementing food policies that encourage the consumption of healthier foods, and regulating the sale of unhealthy foods. Additionally, governments can provide subsidies and other incentives to promote the availability of healthy foods, such as fresh produce, lean proteins, and whole grain foods.

In addition to government involvement, other sectors, such as industry, public health, and civil society, can be involved in promoting healthier dietary habits. Industry can produce healthier food choices, public health can educate people about healthy eating, and civil society can advocate for greater access to healthier food options.


Ultimately, the key to healthy eating is finding a balanced diet that provides the body with essential nutrients while also having a low risk of chronic diseases and illnesses. A nutritious diet should comprise all five food groups, using unsaturated oils where possible, with minimal intake of free sugars, salt and sodium, while taking into consideration establishing personal goals and sustaining a balanced diet in the long-term.

By constructing dietary habits around the principles of a healthy diet, individuals can reduce their risk of heart disease, stroke and other noncommunicable diseases. To help promote healthy diets, governments, industry, public health bodies and civil society must all work collaboratively to share information about establishing dietary goals and sustainable nutrition habits. Educational campaigns and information programs are particularly important aspects for achieving this. Additionally, there is scope to create initiatives to raise awareness of the importance of healthy eating among members of the public and the media, in order to make positive impacts on people’s lifestyles.

Finally, it is important to remember that creating a healthy diet plan does not have to be time consuming or outcome focused; small improvements can lead to big benefits in terms of one’s health. The main priority should be to find a way of eating that works for you, rather than following strict guidelines, and this will enable individuals to attain better nutritional habits which will ultimately improve their overall health.
