People have been searching for ways to extend their lifespan. This may be possible. All they need is to make small changes in their diets. This simple adjustment may reduce mortality from heart disease and cancer and may even add adds 10 to 13 years to their lives.
Large dietary studies have somewhat been useless. The larger they become, the more impossible it will be for them to replicate real-life scenarios and more importantly, represent the genetics of people they’ve been looking into.
However, there’s also a large meta-analysis that discovered how a 20 year-old woman removed refined grains from her meals and replaced them with legumes and whole grains. She also increased her fish and nuts consumption. The researchers saw that this may possibly add as much as 10 years of life expectancy because the food trains her body to fight heart disease and cancer. The same case will be even more beneficial for a 20 year-old man. They say that this could add as much as 13 years more.
These results they came up with are based on research that didn’t delve deeper into nutritional requirements. Instead, they just looked at the caloric intake. This means that they may have excluded the well-established belief that energy restriction often is tantamount to longevity once the nutrient specific needs of the person are met.
However, this has been worth studying because there is perhaps a decade extra of protection from the most common causes of death. As they studied the data on food consumption, the researchers found that most Americans consume closer to the optimal amounts of fruits and vegetables than they did for the ideal amounts of whole grains, legumes, and nuts. Findings somewhat lead to the fact that increasing the intake of these foods and decreasing the intake of processed grains and grain-based processed foods, is the best way to up the life-expectancy.
The findings have a lot of interesting facts about nuts, legumes, and whole grains. The details have been worth the attention. The many sources of complex carbs are rich in fiber, which is another nutrient of concern in the U.S. because these have significant impacts on the person’s health and the risk for cancer risks in the years that passed.
Aside from replacing rice and pasta out with more beans or lentils as the carbohydrate at night, there’s actually an easy rule of thumb to follow when you opt for grains to eat for breakfast and lunch as well. Under a food’s “Total Carbs” is a stated amount that is equal to both of the fiber and simple carbohydrates. The percentage of both of these need to be as high as possible.
Refined grains are also worthy of note because this means they don’t contain the bran, germ, casing, and other aspects of the grain that are not as easily digested. The food doesn’t stay as a whole long enough to get to the colon and large intestines, where bacterial species found there ferment it and produce short-chain fatty acids such as butyrate. This process extremely important to the health of the GI-tract, the immune system, and considering the impact of gut microbes on the person’s mental capacity via the activity that takes place in the vagus nerve, the neural health will benefit from it as well.
However, the topic of most concern is the need to reduce the consumption of red and processed meats that most people do enjoy. However, very much similar this 2019 meta-analysis of randomized controlled trials warns, observational studies are oftentimes open to bias. Hence, it’s difficult to control for all the astounding factors that come in infinitely-variable numbers. In fact, the researchers at the Cochrane Centers in Spain and Poland found that of all the randomized, placebo-controlled trials that looked into red and processed meat consumption, there’s no health benefit if you limit them during your meals.
One could look into the pervasiveness of nutritional deficiencies of vitamin B12, choline, and iron the U.S. The nutrients found in large amounts in red meat, and that since the findings of the new longevity study didn’t create a control for nutrient deficiencies, red meat consumption can be continued so long as the person also engages in more active pursuits.
The studies may have used control for exercise, but it’s still unclear if the degree of exercise needs to be counted or how much is needed. It’s also unclear how the hours spent sitting in a day, which is sometimes just as important than exercising, can be vital. Thus, they came up with the conclusion that like most of the big dietary studies that have been done, the findings should still be open for interpretation.
