“The manufacturers of pureed vegetables for babies used to put large amounts of salt, sugar, and monosodium glutamate into their products, because the added chemicals served as instinctual signals that made the material somewhat acceptable to the babies. There was no scientific basis for providing these vegetables to babies in a form that they would accept, but it was a profitable practice that was compatible with the social pressure against prolonged breast feeding.” -Ray Peat
“Katherina Dalton observed that her patients who suffered from PMS (and were benefitted by progesterone treatment) were likely to develop “toxemia” when they became pregnant, and to have problems at the time of menopause. In these women, it is common for “menstruation” to continue on the normal cycle during the first several months of pregnancy. This cyclic bleeding seems to represent times of an increased ratio of estrogen to progesterone, and during such periods of cyclic bleeding the risk of miscarriage is high. Researchers found that a single injection of progesterone could sometimes eliminate the signs of toxemia for the remainder of the pregnancy. Katherina Dalton, who continued to give her patients progesterone throughout pregnancy, later learned that the babies treated in this way were remarkably healthy and bright, while the average baby delivered after a “toxemic” pregnancy has an IQ of only 85.
Marian Diamond’s work with rats clearly showed that increased exposure to estrogen during pregnancy reduced the size of the cerebral cortex and the animals’ ability to learn, while progesterone increased the brain size and intelligence. Zamenhof’s studies suggested that these hormones probably have their effects largely through their actions on glucose, though they also affect the availability of oxygen in the same way, and have a variety of direct effects on brain cells that would operate toward the same end.
If Katherina Dalton’s patients’ IQs averaged 130, instead of the expected 85, the potential social effects of proper health care during pregnancy are enormous.
But there is evidence that healthy gestation affects more than just the IQ. Strength of character, ability to reason abstractly, and the absence of physical defects, for example, are strongly associated with weight at birth.
Government studies and Social Security statistics suggest the size of the problem. The National Institute of Neurological Diseases and Stroke found that birth weight was directly related to IQ at age four, and that up to half of all children who were underweight at birth have an IQ under 70.(Chase.) According to standard definitions, about 8% of babies in the U.S. have low birth weight.” -Ray Peat
“Even in rich cultures, protein deficiency, inappropriate exercise, and emotional tension will contribute to premature aging of the individual, and damage to the offspring.” -Ray Peat
“Polyunsaturated fats are another clearly identified cause of cancer, especially breast cancer. These fats synergize with estrogen, and sensitize to radiation. Their effects on the mother can be seen in the offspring, as an increased tendency to develop breast or prostate cancer.” Dr. Ray Peat, PhD
“Carrageenan has been found to cause colitis and anaphylaxis in humans, but it is often present in baby “formulas” and a wide range of milk products, with the result that many people have come to believe that it was the milk-product that was responsible for their allergic symptoms. Because the regulators claim that it is a safe natural substance, it is very likely that it sometimes appears in foods that don’t list it on the label, for example when it is part of another ingredient.” -Ray Peat
“Since the custom of giving large iron supplements to pregnant women has been established, there has been an increase in jaundice of the newborn. It has been observed that women who didn’t take iron supplements during pregnancy have healthy babies that don’t develop jaundice. I have suggested that this could be because they haven’t been poisoned by iron. Those supplements could also be a factor in the increased incidence of childhood cancer.” -Ray Peat
“There have been a series of claims that babies’ brains or eyes develop better when their diets are supplemented with certain unsaturated oils, based on the idea that diets may be deficient in certain types of oil, Some experimenters claim that the supplements have improved the mental development of babies, but other researchers find that the supplemented babies have poorer mental development. But the oils that are added to the babies’ diets are derived from fish or algae, and contain a great variety of substances (such as vitamins) other than the unsaturated fatty acids, and the researchers consistently fail to control for the effects of such substances.
It has shown that it is probably impossible to experience a detectable deficiency of linoleic acid outside of the laboratory setting,[69] but the real issue is probably whether the amount in the normal diet is harmful to development. Until the research with animals has produced a better understanding of the effects of unsaturated oils, experimenting on human babies seems hard to justify.” -Ray Peat“Some researchers are concerned that the iron added to cereals is contributing to the incidence of leukemia and cancers of the lymphatic tissues in children. [Goodfield, 1984.] During the time of rapid growth, children are less likely than adults to store too much iron. At birth, they have a large amount of stored iron, and this decreases as they “grow into it.” It is after puberty, when growth slows and the sex hormones are high, that the storage of iron increases. [Blood, Sept., 1976.] In a study of the “malnourished” children of migrant fruit pickers in California, these children who were “seriously anemic” were actually more resistant to infectious diseases than were the “well nourished” middle class children in the same region.”- Ray Peat
“Some studies have suggested that trace amounts of nutrients could be passed on for a few generations, but the evidence now indicates that these transgenerational effects are caused by phenomena such as “imprinting.” But the hereditary effects of nutrients are so complex that their recognition would force nutrition to be recognized as one of the most complex sciences, interwoven with the complexities of growth and development.” -Ray Peat
“The idea that poor nutrition stunts growth has led to the idea that good nutrition can be defined in terms of the rate of growth and the size ultimately reached. In medicine, it is common to refer to an obese specimen as “well nourished,” as if quantity of food and quantity of tissue were necessarily good things. But poisons can stimulate growth (“hormesis”), and food restriction can extend longevity. We still have to determine basic things such as the optimal rate of growth, and the optimal size.” -Ray Peat
