Lectins are large proteins that serve as a crucial weapon that plants use to defend themselves. The lectins in most plants bind to carbohydrates as we consume the plant. They also bind to sugar molecules found in the gut, in the brain, between nerve endings, in joints and in all bodily fluids. According to Dr. Steven Gundry, these sticky proteins can interrupt messaging between cells and cause toxic and inflammatory reactions. Brain fog is just one result of lectins interrupting communication between nerves. An upset stomach is another common symptom of lectin overload. Dr. Gundry lists a wide range of other health problems including aching joints, dementia, headaches and infertility that have been resolved in his patients once they eliminated lectins from their diets. Dr. Paul Saladino writes that the hypothesis that lectins are involved in Parkinson's disease is also gaining support, with animal studies showing that ‘lectins, once eaten, may be damaging the gut and travelling to the brain, where they appear to be toxic to dopaminergic neurons'

Technology changes how individuals and societies understand the concept of privacy. The fact that someone has a new ability to access information or watch the actions of another does not justify doing so. Rather, advances in technology require citizens and policy makers to consider how privacy protections should be expanded. For example, when cameras first became available for commercial and private use, nations and citizens struggled over whether new laws should be enacted to protect individuals from being photographed without their permission. The reconsideration of privacy brought about by this new technology re-affirmed a distinction between private and public spaces. It was determined by most cultures that people automatically gave consent to being seen ― and thus recorded ―once they voluntarily stepped into a public space. Although some people might be uncomfortable with the spread of surveillance cameras, citizens in most cultures have adjusted to the fact that giving up the right not to be observed in these circumstances causes less harm to the community than failing to have surveillance.
