On the road to longevity and health,"Eat a light diet"It has become an iron law in the lives of many middle-aged and elderly people. The logic behind this diet seems simple and straightforward: reduce your intake of salt, oil, and sugar to prevent high blood pressure, lipodystrophy, and other metabolic diseases. However, does the benefits really outweigh the disadvantages? Over time, some professionals have begun to point out that excessive dietary restrictions may not always bring the desired health effects. In fact, undernutrition can also be a threat to a group, especially for middle-aged and older people whose bodies have more specific nutritional needs.
Salt, as an indispensable condiment in daily diet, is mainly composed of sodium chloride, which plays a non-negligible role in maintaining physiological functions. Proper salt levels can help maintain electrolyte balance in the body, which is essential for heart function, muscle activity, and nerve conduction. However, in older adults, excessive salt restriction often leads to loss of appetite, which in turn affects nutrient intake, especially for individuals with pre-existing digestion and absorption problems.
In the daily diet, it is recommended to obtain the right amount of salt through the selection of natural ingredients, such as seafood, fermented foods with low salt content, etc., and avoid adding too much refined salt to reduce excessive sodium intake. In addition, the use of potassium-containing salts instead of some regular table salts can further help regulate the sodium-potassium balance in the body, which can help with blood pressure control.
Fats, especially unsaturated fatty acids, are important nutrients for the elderly to maintain good health. Not only are they important for energy**, they are also an important part of cell membranes and play a key role in the absorption of fat-soluble vitamins. Therefore, a diet that completely eliminates fat is not advisable for older people.
It's important to choose healthy fats**, such as -3 unsaturated fatty acids in deep-sea fish and -6 fatty acids in vegetable oils (e.g., olive oil, flaxseed oil), which can help reduce the risk of cardiovascular disease and are also beneficial for brain health. Moderate intake of these healthy fats can promote good health, rather than a fat-free diet.
Carbohydrates are the body's main energy**, and their proportion in the diet cannot be ignored. However, for older adults, choosing foods with a low glycemic index (GI) is even more critical, which can help avoid sharp fluctuations in blood sugar levels and reduce the risk of metabolic diseases such as diabetes. Foods such as whole grains, legumes and some root vegetables are not only carbohydrate enough to meet daily energy needs, but also to help control blood sugar.
By eating a diet that is high in fibre and high in protein in moderation, you can further optimize your plate, ensure your body's energy intake, and help delay the rise in blood sugar after a meal.
Processed foods often contain high levels of additives, preservatives and artificial colors, which can have adverse health effects when ingested over a long period of time. In contrast, fresh, unprocessed ingredients are more beneficial to health. For example, fresh vegetables and fruits, meat and fish that are not overly processed, and whole grains and legumes are natural foods that not only provide rich nutrients, but also help reduce the intake of unhealthy additives.
By increasing the choice of these natural foods, the quality of the diet can be significantly improved and good health can be promoted. In addition, it is also a good option to prepare your own food, which not only controls how well the food is processed, but also adjusts it to the individual's health needs and taste preferences.
