Refined starch, added sugar
Many familiar snacks such as cookies, french fries, candies... contain very high levels of added sugar and refined carbohydrates. This group of substances is directly related to a series of chronic health problems such as diabetes, obesity and insulin resistance.
A diet high in refined starch and sugar causes blood sugar levels to continuously spike. This increases oxidative stress and mild inflammatory reactions - 2 main factors that accelerate the aging process and lead to negative consequences for health.
In particular, insulin sensitivity tends to gradually decrease with age. In older adults, blood sugar levels after meals often spike higher and take longer to recover to a balanced level.
When the aging body is already ineffective in self-regulating blood sugar, sugary snacks are even more likely to be harmful. Therefore, cutting down on processed snacks is a key starting point to control blood sugar in old age.
Deficiency of essential nutrients
Processed snacks are low in fiber, protein, and micronutrients. This creates major obstacles for the elderly - a group that requires optimal nutrition to maintain physical condition.
For example, getting enough protein is a mandatory requirement to prevent muscle atrophy due to age. Supplementing enough fiber in each main meal and snack is the key to maintaining digestive health.
High sodium content
Some types of french fries, crackers, processed meat, and packaged fast food contain very high levels of sodium. This is a cause of increased risk of high blood pressure, heart disease, stroke, and kidney failure.
Excess salt from processed foods not only increases blood pressure but also directly damages the endothelium lining inside the arteries. Over time, this impact promotes vascular stiffness, exacerbating chronic diseases common in old age such as cardiovascular disease, kidney dysfunction and cognitive decline.
