Anemia Good Quotes

Over the past fifteen years, the iconoclastic mathematician Irakli Loladze has isolated a dramatic effect of carbon dioxide on human nutrition unanticipated by plant physiologists: it can make plants bigger, but those bigger plants are less nutritious. “Every leaf and every grass blade on earth makes more and more sugars as CO2 levels keep rising,” Loladze told Politico, in a story about his work headlined “The Great Nutrient Collapse.” “We are witnessing the greatest injection of carbohydrates into the biosphere in human history—[an] injection that dilutes other nutrients in our food supply.” Since 1950, much of the good stuff in the plants we grow—protein, calcium, iron, vitamin C, to name just four—has declined by as much as one-third, a landmark 2004 study showed. Everything is becoming more like junk food. Even the protein content of bee pollen has dropped by a third. The problem has gotten worse as carbon concentrations have gotten worse. Recently, researchers estimated that by 2050 as many as 150 million people in the developing world will be at risk of protein deficiency as the result of nutrient collapse, since so many of the world’s poor depend on crops, rather than animal meat, for protein; 138 million could suffer from a deficiency of zinc, essential to healthy pregnancies; and 1.4 billion could face a dramatic decline in dietary iron—pointing to a possible epidemic of anemia. In 2018, a team led by Chunwu Zhu looked at the protein content of eighteen different strains of rice, the staple crop for more than 2 billion people, and found that more carbon dioxide in the air produced nutritional declines across the board—drops in protein content, as well as in iron, zinc, and vitamins B1, B2, B5, and B9. Really everything but vitamin E. Overall, the researchers found that, acting just through that single crop, rice, carbon emissions could imperil the health of 600 million people. In previous centuries, empires were built on that crop. Climate change promises another, an empire of hunger, erected among the world’s poor.

We now know that selenium makes two vital enzymes, deficiency in which has been linked to hypertension, arthritis, anemia, some cancers, and even, possibly, reduced sperm counts. So, clearly it is a good idea to get some selenium inside you (it is found particularly in nuts, whole wheat bread, and fish), but at the same time if you take in too much you can irremediably poison your liver.

The scariest thing is that nobody seems to be considering the impact on those wild fish of fish farming on the scale that is now being proposed on the coast of Norway or in the open ocean off the United States. Fish farming, even with conventional techniques, changes fish within a few generations from an animal like a wild buffalo or a wildebeest to the equivalent of a domestic cow. Domesticated salmon, after several generations, are fat, listless things that are good at putting on weight, not swimming up fast-moving rivers. When they get into a river and breed with wild fish, they can damage the wild fish's prospects of surviving to reproduce. When domesticated fish breed with wild fish, studies indicate the breeding success initially goes up, then slumps as the genetically different offspring are far less successful at returning to the river. Many of the salmon in Norwegian rivers, which used to have fine runs of unusually large fish, are now of farmed origin. Domesticated salmon are also prone to potentially lethal diseases, such as infectious salmon anemia, which has meant many thousands have had to be quarantined or killed. They are also prone to the parasite Gyrodactylus salaris, which has meant that whole river systems in Norway have had to be poisoned with the insecticide rotenone and restocked.

More food is good, but agricultural diets can provoke mismatch diseases. One of the biggest problems is a loss of nutritional variety and quality. Hunter-gatherers survive because they eat just about anything and everything that is edible. Hunter-gatherers therefore necessarily consume an extremely diverse diet, typically including many dozens of plant species in any given season.26 In contrast, farmers sacrifice quality and diversity for quantity by focusing their efforts on just a few staple crops with high yields. It is likely that more than 50 percent of the calories you consume today derived from rice, corn, wheat, or potatoes. Other crops that have sometimes served as staples for farmers include grains like millet, barley, and rye and starchy roots such as taro and cassava. Staple crops can be grown easily in massive quantities, they are rich in calories, and they can be stored for long periods of time after harvest. One of their chief drawbacks, however, is that they tend to be much less rich in vitamins and minerals than most of the wild plants consumed by hunter-gatherers and other primates.27 Farmers who rely too much on staple crops without supplemental foods such as meat, fruits, and other vegetables (especially legumes) risk nutritional deficiencies. Unlike hunter-gatherers, farmers are susceptible to diseases such as scurvy (from insufficient vitamin C), pellagra (from insufficient vitamin B3), beriberi (from insufficient vitamin B1), goiter (from insufficient iodine), and anemia (from insufficient iron).28 Relying heavily on a few crops—sometimes just one crop—has other serious disadvantages, the biggest being the potential for periodic food shortages and famine. Humans,

DNA will be stored by the clinic or government. Why not screen the baby before it’s born? Advances in genetic technology allow embryos to be screened for hundreds of genetic risk factors, including Down syndrome, breast cancer, and sickle-cell anemia, using nothing but a blood sample from the mother. Parents who desire the ideal baby, and nothing less, will go for that. Already companies are offering services from pre-implantation diagnoses to direct-to-consumer genetic testing. Genetic technology will impact our emotions and values. Some parents see genetic optimization as a great possibility and a basic right; others are morally appalled by the thought of designer babies. One thing we can be sure of is that genetic screening will lead to more abortions. Moreover, if parents decide

the preamble of the National Sickle Cell Anemia Control Act, enacted in 1972 to foster sickle-cell research, screening, counseling, and education, is untrue: “Two million Americans suffer from sickle cell disease.” Actually, 2 million people were healthy carriers22 and fewer than 100,000 Americans suffered from sickle-cell anemia. The erroneous claim coupled with its constantly reinforced perception of sickle-cell disease as a black disorder left Americans with the mistaken impression that a good portion—one in twelve—of African Americans suffered from sickle-cell anemia.

Gluten, a major component of wheat, barley, and rye, is a composite of two different proteins, gliadin and glutelin. Gluten is what gives bread its stretchiness and elasticity, qualities most folks enjoy. But gluten also makes some people seriously ill. It is estimated that about 1 percent of the population is gluten intolerant, though most are unaware of it. If gluten-intolerant individuals eat gluten grains, they develop what’s known as celiac disease. Celiac disease is an autoimmune condition in which the gliadin protein in gluten grains generates an antibody-mediated immune-system attack against the intestines, leading to chronic diarrhea, fatigue, stunting of growth, vitamin and mineral deficiencies, anemia, nerve damage, and osteoporosis. Furthermore, those with celiac disease have higher rates of cancer, schizophrenia, and a whole host of autoimmune illnesses (Jackson et al. 2012; Rubio-Tapia and Murray 2010), suggesting that the body’s response to gluten affects more than just the intestines. And, on the flip side, almost every chronic autoimmune disease we know of is associated with a significantly increased risk of celiac disease (Cosnes et al. 2008; Rousset 2004; Rodrigo et al. 2011; Song and Choi 2004).
