Poor diet is a leading cause of disease and death worldwide. Research has shown that 11 million deaths annually are linked to diet-related diseases, such as diabetes, heart disease, and cancer. High sodium intake, low fruit intake, and low whole grain intake are among the top dietary risk factors contributing to these deaths. In the United States, nearly half of all deaths caused by cardiometabolic diseases in 2012 were associated with unhealthy eating habits, including excessive consumption of processed meats, sugar-sweetened beverages, and sodium. Ultra-processed foods, in particular, have been linked to various health issues, including inflammation, heart disease, Alzheimer's, and cancer. These findings highlight the urgent need for improving diets and implementing policies to address malnutrition and non-communicable diseases globally.

What You'll Learn
High sodium intake
The short-term effects of high sodium intake include bloating, as it causes the body to retain water, resulting in extra fluid buildup. The long-term effects are much more serious and include an enlarged heart muscle, headaches, heart failure, high blood pressure, kidney disease, kidney stones, osteoporosis, stomach cancer, and stroke. High sodium intake can also increase an individual's risk of dying from heart disease, as it can lead to high blood pressure, which is one of the most common causes of heart disease.
To reduce sodium intake, it is important to be aware of how much sodium is being consumed and to prioritize low-sodium foods while limiting high-sodium ones. This can be achieved by choosing fresh meats instead of packaged ones, opting for \"fresh frozen\" frozen vegetables, and avoiding those with added seasoning or sauces. Reading labels and checking the sodium content of foods is crucial, as is choosing spices and seasonings that do not contain sodium. When dining out, it is also possible to request that your dish be prepared without salt.

Low fruit and vegetable intake
Diet is a leading risk factor for deaths worldwide, with about 11 million deaths annually linked to diet-related diseases. A study found that nearly half of all deaths in the United States in 2012 caused by cardiometabolic diseases were associated with poor eating habits. Low fruit and vegetable intake is a significant contributor to this issue.
Fruits and vegetables are important components of a healthy diet. They are rich sources of vitamins, minerals, dietary fiber, and beneficial non-nutrient substances such as antioxidants. A diet that includes adequate amounts of fruits and vegetables can provide numerous health benefits, including lower blood pressure, a reduced risk of heart disease, stroke, and certain types of cancer, as well as improved digestive health.
The World Health Organization (WHO) suggests consuming more than 400 grams of fruits and vegetables per day as part of a healthy diet low in fat, sugars, and salt/sodium to improve overall health and reduce the risk of non-communicable diseases (NCDs). However, many individuals do not meet these recommendations. In low- and middle-income countries (LMICs), for example, 67.2% of individuals had inadequate fruit and vegetable consumption.
The consequences of low fruit and vegetable intake can be dire. Research suggests that this dietary habit may be a major factor in the high number of cardiovascular deaths worldwide. Specifically, low fruit consumption has been linked to more than 1 million deaths from stroke and over 500,000 deaths from heart disease annually, while low vegetable intake is associated with approximately 200,000 stroke deaths and more than 800,000 heart disease deaths each year. Inadequate fruit and vegetable intake has also been independently associated with a higher risk of chronic lung disease, diabetes, hearing problems, and visual impairment.
To address this issue, population-based efforts are needed to increase fruit and vegetable consumption globally. This may include promoting the consumption of at least two servings of fruits and three servings of vegetables per day, especially in regions with low average intake, such as South Asia, East Asia, and Sub-Saharan Africa. By making small changes to our diets and incorporating more fruits and vegetables, we can significantly improve our health and reduce the risk of diet-related diseases.

Low whole grain intake
Whole grains are an essential part of a healthy diet and offer a "complete package" of health benefits. Whole grains are a good source of B vitamins, vitamin E, fiber, and other health-promoting components such as phytochemicals.
The 2015-2020 Dietary Guidelines for Americans recommend eating 6 ounces of grain foods daily, with at least half of that intake coming from 100% whole grains. Unfortunately, many people do not consume enough whole grains, which can have negative health consequences. According to a study by the National Institutes of Health, low whole grain intake was associated with a 5.9% increased risk of cardiometabolic disease-related death.
Cardiometabolic diseases include heart disease, stroke, and type 2 diabetes, which are some of the leading causes of death worldwide. Poor diet, in general, is a significant risk factor for these diseases, and ultra-processed foods, in particular, have been linked to inflammation and various health issues, including heart disease, Alzheimer's, and cancer.
Overall, increasing whole grain intake is an important part of maintaining a healthy diet and reducing the risk of various diseases, including cardiometabolic diseases and certain types of cancer.

High processed meat consumption
Diet is a leading risk factor for deaths worldwide, with about 11 million deaths annually linked to diet-related diseases. Unhealthy diets can increase the risk of dying from heart disease, stroke, and Type 2 diabetes.
Furthermore, high processed meat consumption has been linked to a higher risk of diabetes. The same University of Oxford study found that for every 70 grams higher intake of processed meat, there was a 30% higher risk of diabetes.
Overall, the evidence suggests that high processed meat consumption is detrimental to health and can increase the risk of various diseases, including cancer, heart disease, and diabetes. It is advisable to limit or avoid processed meat consumption to reduce these health risks.

High sugar intake
Excess sugar consumption can also contribute to weight gain, as it tricks the body into turning off its appetite-control system, making it easier to add more calories to one's diet. This can lead to a higher risk of developing heart disease and coronary complications compared to those who consume less sugar. Additionally, high sugar intake has been associated with an increased risk of stroke and atherosclerosis, a disease characterized by fatty, artery-clogging deposits.
The liver is also affected by high sugar intake. Fructose, a common type of sugar, is almost exclusively broken down by the liver and can lead to non-alcoholic fatty liver disease (NAFLD) when consumed in excess. This is because the liver can only store a certain amount of glycogen before excess amounts are turned into fat. Over time, this can lead to a greater accumulation of fat, which may turn into fatty liver disease, a contributor to diabetes and an increased risk of heart disease.
High-sugar diets have also been linked to an increased risk of dementia, Alzheimer's disease, and cognitive decline. Research suggests that sugar overconsumption can affect mood, causing compulsivity and impulsive behaviour, which are predictors of substance use disorder (SUD). Additionally, epidemiological data showed increases in depressive and anxiety behaviours in patients with histories of high-sugar diets and drug use.
It is important to note that sugar is not a necessary nutrient in the diet, and reducing sugar intake can be beneficial for overall health. Monitoring sugar intake by reading food labels and tracking added sugars can help individuals make more informed dietary choices and potentially reduce their risk of developing diseases associated with high sugar intake.
