Design: The study was a cross-sectional study. Methodology: A structured validated questionnaire was used to obtain demographics. A 3-day 24-hour dietary recall and usual food intake questionnaire were used to obtain information on food intakes and dietary pattern of the respondents. Food models, household measures and photos of common dishes as well as household cups and measures were used in order to obtain accurate information regarding the types and quantities of foods and beverages consumed. Subjects: Convenient sampling was used to select bank branches while simple random sampling by ballot without replacement was used to select 119 bank employees who consented to participate in the study. Outcome measures: Data were analysed using Statistical Package for the Social Sciences software. Esha FPro software was used to analyse food nutrients. The nutrient intakes were compared with a standard dietary guideline for adults. Results: Findings showed significant (p < 0.05) differences in mean energy intake between males and females. Also, the bank employees were consuming more fat (32%) compared with the recommended intake. The average intake of dietary sodium and cholesterol was within the recommended intake levels. All the participants in the study had a mean intake of dietary potassium, fibre, fruits and vegetables below the recommended levels. The major cooking oils used in meal preparation were vegetable and palm oil (46%), followed by vegetable oil (31.9%) and palm oil (21.8%). Conclusions: The study evaluated the dietary intake of bank employees, which is an important risk factor for chronic diseases. There is a need to develop plans to provide nutrition education and counselling for adequate nutrient intake and prevention of chronic diseases among bank employees. Layman’s summary: Obtaining an adequate diet and avoiding overconsumption of food helps to maintain health. Intake of foods containing high energy and fats without corresponding energy expenditure through physical activity could result in obesity, heart diseases, diabetes and other health challenges. Inadequate intake of micronutrients as well could result in deficiency diseases, and depresses the immune system and health of individuals. Bank employees and all other individuals need to pay attention to what they eat to live a healthy and longer life. Regular physical activity, following the dietary approaches to avoid hypertension and regular medical check-up are essential for cardiovascular health. Strong lay message: Inadequate or overconsumption of nutrients can cause chronic heart diseases.

Generally, the mean Dietary intake as a cardiovascular risk factor 5 Hypertension is one of the most common CVDs in Ghana.14 It could precipitate other cardiovascular diseases as well as renal disease.12 Consumption of dietary iron among the respondents was signifi- cantly higher in males than in females. However, both genders’ intake of iron was higher than the recommended dietary intake but did not exceed the upper adult tolerable level of 45 mg/day.12 This could be attributed to the consumption of meat, fish and poultry, which are rich in iron.12 Adequate dietary iron intake will ensure prevention of anaemia and boosts the immune system.12 Micronutrients such as excess intake of sodium and low potassium intake are strongly related to the risk of developing CVD.12 Findings of the study showed that the mean intake of dietary sodium (773 mg) of all the bank employees was within the recommended intake (< 2 400 mg). Dietary sodium has long been labelled as a dietary factor in the pathogenesis of high blood pressure.21 Sodium is positively associated with blood pressure, therefore the mean intake found in this study is favourable for health.12 However, these results should be interpreted with caution since the dietary assessment method of estimating sodium intake is less reliable as it may be associated with misreporting and some people cook with different levels of salt.

All the participants in the study had a dietary potassium intake (841 mg) below the recommended intake of 4 700 mg of dietary potassium per day. This may partly be due to the low intake of fruits and vegetables among the bank employees. Fruits and vegetables affect cardiovascular risk through their high potassium levels that serve to modulate blood pressure.23 Potassium has a negative association with blood pressure.24,25 Therefore low intakes of dietary potassium may predispose to the high prevalence of hypertension. The majority of the bank employees had a daily intake of fruits and vegetables below the daily recommended intakes of 4–5 servings a day for each, respectively, in the dietary approaches to stop hypertension.4,12 The recommendation for fruits and Figure 2: Most common type of oil used. vegetables was for individuals to eat at least three servings of fruit and at least four servings of vegetables each day for intakes were within the recommended daily intake of adults.26 Making a choice from fresh, frozen, dried or canned < 300 mg a day.4,5 The effect of diet on serum lipids and lipo- forms and a variety of colours and kinds is encouraged.
