Low-protein diet throughout pregnancy and lactation may increase risk of liver damage
The team believes that all these biomarkers indicate a risk of disease. For instance, high cholesterol levels are tied to an increased risk of cardiovascular disease. With a person’s long-term dietary habits, these can affect one’s health outcomes.
For people with high cholesterol levels, they are more likely to develop cardiovascular disease. Atherosclerosis is a condition wherein plaque builds up inside the arteries, making it harder for blood to flow. Arteries carry oxygenated blood that delivers the needed oxygen and nutrients to the different parts of the body. Plaque is mostly made of fat, calcium, cholesterol and other substances found in the blood.
When a plaque hardens and accumulates over time, it can narrow the blood vessel. If there is no enough oxygen reaching the heart and brain, it can lead to potentially fatal conditions such as heart attack and stroke. The American diet
The Food and Nutrition Board of the National Academy of Medicine recommends an average daily requirement of 15mg/kg/day. To estimate the intake of people of high-protein foods, the nutritionists collated information about the diet of the participants through 24-hour recalls. With the use of the U.S. Department of Agriculture Survey Nutrient Database, the team calculated the intake of each participant.
The team revealed that the average American consumes about two and a half times more sulfur amino acids than the average recommendations, based on their type of diet, which is more of meat and dairy products.
“Many people in the United States consume a diet rich in meat and dairy products and the estimated average requirement is only expected to meet the needs of half of the healthy individuals. Therefore, it is not surprising that many are surpassing the average requirement when considering these foods contain higher amounts of sulfur amino acids,” Xiang Gao, associate professor and director of the nutritional epidemiology lab at the Penn State University.
The team also found that the higher the sulfur amino acids, the higher the cardiovascular risk. They also recommended eating a plant-based diet like fruits and vegetables since they have lower amounts of sulfur amino acids.
Eating a plant-based diet has been linked to a lower risk of heart disease. The researchers aim to emphasize that eating a well-balanced diet is a good practice for overall health. Journal reference:
