Animal-products in the Human Diet

My apologies to any non-meat eaters in the class, but I have uncovered evidence of animal-products being beneficial to health.  Having animal-products in the diet requires a delicate balance.  Overconsumption of animal-products is detrimental to human health. Animal-source foods are an excellent source of energy, essential micronutrients, and protein.  These foods provide the nutrients necessary for physiological functioning, development, and overall good health. Smith et al. give the example of food security as when everyone in the population has adequate, nutritious, and safe food at all times (2013).  Food security places an emphasis on food quantity.  Nutrition security is the focus of the quality of food.  Livestock is a direct contribution to nutrition security and is one of the best sources for quality protein.  Because of this, animal-source food can enhance food and nutrition security.  Additionally, livestock can provide an income for people and increase chances for education.  This can ultimately improve a community by providing education to children in poverty and make these children into healthy and well-educated adults (Smith et al., 2013).
Animal-products can also have a negative impact.  Keeping livestock decreases the food supply for humans because livestock consume a large portion of the world’s production of grains.  Smith et al. reported ½ of the world’s production of grains being consumed by monogastrics (2013).  Another factor against animal-source foods is that they are expensive.  People in poverty tend to sell the animal products they make instead of consuming them.  It is estimated that animal production is contributing a large and essential part of income for more than one billion people in Asia and Africa (Smith et al., 2013).
Livestock agriculture currently supports the livelihoods of approximately 675 million of the rural poor, who can depend on livestock for part or all of their income/food (Steinfeld, 2003).  Raising livestock can supply a stable source of food and income.  This provides the opportunity to raise a farm’s whole productivity.  Livestock is sometimes the only viable option for the landless in developing countries.  Availability of land will limit expansion in some regions. Increased productivity will come from more adoption of current and new production and marketing technologies (Steinfeld, 2003).

  1. Excellent post Erin!! And also there is evidence that increased livestock/ animal product consumption contributes to climate change. So, what steps do you advise we should take to not create further imbalances in the already complex situation in global health?

    1. In respect to climate change, one of the suggested solutions is to move meat consumption towards less beef. Beef production is always blamed for the overabundance of methane in the environment. Fish and broiler production are less likely to be as problematic, so encouraging the human diet towards these types of meat is not only healthy for the human, but also the environment.
