A number of fashionable trends in diet are actually very dangerous. The idea of a low fat diet and a low carbohydrate diet is very dangerous. The brain is composed in large part by fats and brain cells require glucose to function, a major source of glucose is carbohydrates. Vegetarian sources of fat are various oils such as coconut oil and olive oil. Also nuts are a source of vegetarian fat.
The way to prevent any potentially harmful affects of fat is by eating raw a raw garlic clove. Raw garlic helps to unclog the arteries. Raw garlic also is good for unclogging the colon. In ancient greek medicine there is a saying that constipation is the mother of all diseases.
Another dangerous diet fad is the notion that salt is bad. Sodium is essential to live and salt that is unrefined and natural(most table salt is refined salt) is also a source of trace minerals. Salt only becomes harmful if one does not drink water. Without salt people die. Some have alleged that salt helps people feel grounded.
Fat, salt, and carbs are healthy.
