The heavy dependence on fossil energy suggests that the US food system, whether. The use of land and energy resources devoted to an average meat- based diet. In both diets, the daily quantity of calories. The meat- based food system requires more energy, land, and water. In this limited sense, the lactoovovegetarian diet is more sustainable than the. American meat- based diet. The shortages of cropland, fresh water, and energy resources require most of the 4 billion people to. The World Health Organization recently reported that more than 3 billion people are malnourished. This is the largest number and proportion of malnourished people ever recorded in history. In large measure, the food shortage. The US population doubled in the past 6. Figure 1. The US food production system uses about 5. US land area, approximately 8. The heavy dependence on fossil energy suggests that the US food system, whether meat- based or plant- based, is not sustainable.

In the lactoovovegetarian diet, the meat and fish calories were replaced by proportionately increasing most other foods. Table 1. The total weight of food consumed was slightly. The most food calories. Difference Between Plant Based Diet And Vegetarian Protein CombinationsThis is expected because of the relatively large amount of animal products consumed in the meat- based diet (7). Less than 0. 4 ha of cropland was used to produce the food for the vegetarian- based diet, whereas about 0. This reflects the larger amount of land needed to produce the meat- based diet (Table 1. The energy inputs vary according to the crops being grown (1. When these inputs are balanced against their energy and protein content, grains and some legumes, such as soybeans, are. In the United States, the average protein yield from a grain crop such as corn is 7.

This livestock population on average outweighs the US human population by about 5 times. Some livestock, such as poultry. At present, the. US livestock population consumes more than 7 times as much grain as is consumed directly by the entire American population. The amount of grains fed to US livestock is sufficient to feed about 8. From the US livestock population, a total of about 8 million tons (metric) of animal protein is produced annually. With. an average distribution assumed, this protein is sufficient to supply about 7. American. With. the addition of about 3. United States per day (1. Note that the recommended daily allowance (RDA) for adults per day is 5. Therefore, based. American consumes about twice the RDA for protein. Americans on average are eating too much and are consuming. The protein consumed per day on the lactoovovegetarian diet is 8. This is significantly lower than the 1. RDA of 5. 6 g per day. Of the meat eaten, beef amounts to 4. Additional animal protein is. For every 1 kg of high- quality animal protein produced, livestock are. In the conversion of plant protein to animal protein, there are 2 principal inputs or costs. For example, broiler chicken production is the most efficient, with an input of 4 kcal of fossil energy for each 1 kcal. The broiler system is primarily dependent on grain. Turkey, also a grain- fed system, is next. Milk production, based on a mixture of two- thirds grain and one- third forage, is relatively. Both pork and egg production also depend on grain. Pork production has a ratio of 1. The beef system has a ratio of 4. Table 2. If these animals were fed on only good- quality pasture, the energy inputs could be reduced by about half. This energy input is more than 1. Table 4. This is for corn and assumes 9% protein in the corn. Animal protein is a complete protein based on its amino acid profile. The continued. use and productivity of the land is a growing concern because of the rapid rate of soil erosion and degradation throughout. United States and the world. Each year about 9. US cropland loses soil at a rate 1. Also, US pastures and rangelands are losing soil at an average of 6 tons/ha/y. About 6. 0% of United States pastureland is. Clearly, a farmer cannot wait for the replacement of 2. Commercial fertilizers can replace some nutrient loss. The water required to produce various foods and forage crops ranges from 5. L of water per kilogram of crop produced. If irrigation. is required, more than 1. L of water must be applied. Even with 8. 00–1. US Corn Belt. corn usually suffers from lack of water in late July, when the corn is growing the most. Livestock directly uses only 1. However, when the water required for forage and. For example, producing. This much forage and grain requires about 1. L of water to produce the 1. L for the 4 kg of grain. Animals vary in the amounts of water required for their production. In contrast to beef, 1 kg of broiler can be produced. L of water. Thus, both food systems are not sustainable in the long term based on heavy fossil energy requirements. In this limited. sense, the lactoovovegetarian diet is more sustainable than the average American meat- based diet. The US population of 2.
