The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The energy of a fuel per unit mass is called its specific energy. The adjacent figure shows the gravimetric and volumetric energy density of some fuels and storage technologies (modified from the Gasoline article).
As foods vary by brands and stores, the figures should only be considered estimates, with more exact figures often included on product labels. For precise details about vitamins and mineral contents, the USDA source can be used. [1] To use the tables, click on "show" or "hide" at the far right for each food category.
The differing energy density of foods (fat, alcohols, carbohydrates and proteins) lies mainly in their varying proportions of carbon, hydrogen, and oxygen atoms. Carbohydrates that are not easily absorbed, such as fibre, or lactose in lactose-intolerant individuals , contribute less food energy.
Nutrient density identifies the amount of beneficial nutrients in a food product in proportion to e.g. energy content, weight or amount of perceived detrimental nutrients. Terms such as nutrient rich and micronutrient dense refer to similar properties.
“It does create personalized weight loss plans and uses a color-coded system to encourage adding more nutrient-dense whole foods and limiting more calorie-dense foods like fried foods, sugary ...
10 Energy Foods For those of us who are overstressed and sleep-deprived, there's a healthy way—10 actually—to boosts energy and fuels workouts without the pending sugar crash that comes along ...
Food composition datasets (FCDBs) or food composition tables are resources that provide detailed food composition data (FCD) on the nutritionally important components of foods. FCDBs provide values for energy and nutrients including protein , carbohydrates , fat , vitamins and minerals and for other important food components such as fibre .
