Lowering food density benefits primary producers and inhibits carnivores because primary producers will be more spread out spatially, and therefore carnivores have more trouble finding their prey.
Accordingly, nutrition counseling that aims to improve eating habits (i.e. increase fruit and vegetable servings, limit lower nutrient density and higher fat and calorie foods) is a critical component of a successful obesity treatment program [ 28].
Higher scores for unhealthier dietary patterns (with higher consumption of take away foods, meat, confectionary and soft drinks, higher energy density, higher percent of energy from unsaturated fatty acids, lower percent of energy from carbohydrates and lower nutrient densities of several vitamins and minerals) are observed more often among 16- to 17-years old boys and adolescents with lower SES.
The effect of the landscape heterogeneity on the encounter rate was clear in the presence of higher food density than in lower density.
It should be noted that the protein content of the HF diet was 2-fold higher because of the lower food intake (g/day) in these rats due to the higher energy density.
How does VV's fast food density compare to other cities?
Lower food intake among the elderly has been associated with lower intakes of calcium, iron, zinc, B vitamins, and vitamin E. This low energy intake or low nutrient density of the diet may increase the risk of diet-related illnesses.
Three randomized controlled weight loss trials found that lowering food-based energy density by increasing fruit and/or vegetable intake is associated with significant weight loss (de Oliveira et al., 2008; Saquib et al., 2008; Ello-Martin et al., 2007).
Indeed, consuming a diet rich in foods that are lower in nutrient density and fiber and higher in fat and calories, contributes to excessive weight gain [ 28].
Energy-dense food such as sweets or fatty snacks are often less expensive [ 30] compared to food with lower energy density such as fruit or vegetables [ 18, 31].
