Another aspect of nutrition that is important to mention due to its impact on food choices is nutrient density. Nutrient density refers to the amount of macro- and micronutrient(s) present in a food per calorie. For example, meat and many vegetables are dense as they contain high concentrations of energy as well as vitamins and minerals. In contrast, many packaged and processed foods containing mostly sugar, salt, and preservatives lack a similar nutrient density. While larger athletes that consume more food typically do not have an issue with nutrient density, smaller athletes that consume fewer kcals may have to pay more attention to micronutrient (vitamin and mineral) content.

There are challenges and opportunities to the “nutrient density approach to healthy eating”; Nicklas et al. (2014) note that although nutrient-dense foods are “widely recommended,” an agreed-upon definition has not yet been developed, and there is much to be done in both defining and applying the term nutrient density. The paper highlights the potential of this as a tool for the public to use of, to make it easier and clearer for the public to make healthier food choices (Nicklas et al., 2014).
Optimal Nutrition for Women

Nutrient density as described in the dietary guidelines is a:characteristic of foods and beverages that provide vitamins, minerals, and other substances that contribute to adequate nutrient intakes or may have positive health effects, with little or no solid fats and added sugars, refined starches, and sodium. Ideally, these foods and beverages also are in forms that retain naturally occurring components, such as dietary fiber.23
A modified Mediterranean dietary intervention for adults with major depression: Dietary protocol and feasibility data from the SMILES trial

By final assessment, the dietary intake of protein (as a % of EI), polyunsaturated fat (as a % of EI), dietary fibre, vitamin E, long chain (LC) omega-3 PUFAs, and α-linolenic acid had all significantly increased among the diet group (Table 5). This is consistent with improvements in intake of food groups associated with the ModiMedDiet (as noted above). Additionally, carbohydrate intake had significantly decreased by a mean value of 29.6 grams, and as a percentage of total energy (from 44.1 to 40.7%). Conversely, diet quality as measured by nutrient density deteriorated in the control group. Specifically, the intake of energy, thiamin, vitamin E, ß carotene equivalents, potassium, iron, and α-linolenic acid all statistically significantly declined from baseline to final assessment in the control condition (Table 5).
Testing of developed Food Based Dietary Guidelines for the elderly in South Africa

Micronutrient intakes among the black elderly in SA were shown as deficient in vitamins A, B2, B6, C, D, E, K, folate and biotin, as well as calcium, magnesium, copper and selenium.25 Very little recent data are available regarding the micronutrient profile of other elderly persons. The National Food Consumption Survey, however, showed that the overall diet of South Africans is poor21 in terms of micronutrients, hence the importance of sufficient consumption of a diet from all the different food groups, specifically fruit and vegetables. With ageing, nutrient density becomes even more important to sustain health. Older adults often do not include an adequate number of fruits, vegetables and milk products in their diet, affecting their nutritional status.26 Therefore, the guideline on enjoying a variety of food and consuming different coloured vegetables and fruit is important and should be supplemented with various support materials such as images and examples of healthy options.
Nutrition Provides the Essential Foundation for Optimizing Mental Health

We have reviewed several reasons why dietary change may not be sufficient for everyone. Individual differences, stress levels, medication use, and gut health, all provide plausible reasons why nutrient requirements may vary, resulting in a greater need for nutrients in some individuals than what can be obtained from diet alone. In addition, environmental factors such as depleted soil minerals, and climate change can influence the nutrient density of the food we consume. This leads to the question of whether there is evidence for treating mental health problems with supplementary nutrients, especially (but not exclusively) in children.
