Can low-carb or fat diets prolong life in middle-aged?
A healthy low-fat diet has been shown to reduce the risk of cancer, cardiovascular disease, and early death in middle-aged and older persons, according to research.
A healthy low-carbohydrate diet, according to experts, may marginally reduce the risk of early mortality in that age group.
According to experts, as you get older, weight and diet become more crucial, therefore choosing a healthy eating strategy is essential.
A recent study found that the health of middle-aged and older persons can be improved by diets reduced in fat and carbohydrates.
Low-carbohydrate and low-fat diets have been found to be healthy choices for weight loss and heart health in short-term research trials.
The most recent research, which was released in the Journal of Internal Medicine, looks at how such diets affect mortality in middle-aged and older persons.
The study examined 371 159 individuals between the ages of 50 and 71. 165,698 of the participants passed away over the study’s 23-year duration.
According to the researchers, low-saturated-fat diets that are high in plant protein and high-quality carbs are linked to lower risks of death from all causes, including cancer and cardiovascular disease.
A general low-carb diet and a bad low-carb diet, however, were linked to considerably greater rates of overall, cardiovascular, and cancer death. However, a low-carb, healthful diet was linked to somewhat decreased death rates.
“Our results support the importance of maintaining a healthy [low-fat diet] with less saturated fat in preventing all-cause and cause-specific mortality among middle-aged and older people,” the study’s authors said.
Fats and carbohydrates as you get older
The consensus among experts is that as people age, low-carb diets are typically the healthiest option.
However, when it comes to fat, experts advise limiting only the dangerous types of fat and carbohydrates rather than all of them.
It’s critical to distinguish between a healthy carbohydrate or healthy fat and an unhealthy one, according to Kailey Proctor, a dietitian at the City of Hope Orange County Lennar Foundation Cancer Centre in California who specialises in cancer nutrition.
Many people are unaware of the distinctions between basic and complex carbs, as well as saturated and unsaturated fats, according to Proctor, who observes cancer patients daily. “Complex carbs, such those found in whole wheat bread, quinoa, brown rice, and sweet potatoes, can be healthy to consume“. Compared to simple carbs, which have absolutely little nutritional value, including white bread, breakfast cereals, and pastries, these foods are all high in fiber, antioxidants, and micronutrients.
Low-carb, low-fat diets explained
Both diets have been proven to be beneficial for middle-aged people’s health, according to Trista Best, a certified dietitian at Balance One Supplements.
For instance, several low-carb diets encourage the consumption of protein and healthy fats. Not all carbohydrates are created equal, and some healthy carbohydrates like fruits, vegetables, and whole grains can be a crucial component of a balanced diet, according to Best.
She continued, “Low-fat diets have also been found to offer health benefits, including improving cholesterol levels and lowering the risk of heart disease. Low-fat diets typically restrict fat intake and emphasize carbs and protein. But it’s crucial to pick good fats, such as those in nuts, seeds, avocados, and fatty fish.“
Registered dietitian Robert Lafelice works for the fitness brand Set For Set. He claimed that understanding a healthy diet is made simple by seeing it through the perspective of evolution.
All adults should follow a low-carb diet, according to the overwhelming body of research, Lafelice said. “Humans developed over hundreds of thousands of years on a diet high in protein and fat, not carbohydrates. The government’s proposal that we obtain more than half of our energy from carbohydrates is in direct opposition to the original human diet.”
According to Lafelice, a high-carb diet has been linked to everything from diabetes to cancer to dementia. He added that low-fat diets by themselves may not be healthful.
There are needed proteins and fatty acids, but no essential dietary carbohydrates, he claimed. “Eating low fat and high carb is particularly harmful and unhealthy for older folks. We naturally grow more insulin resistance as we get older. Therefore, eating a lot of carbs will only make things worse.”
Middle age diet
Dietician and author Heather Dyc told us that she is a “big fan of low carb, but not low fat, diets for the middle-aged.”
When it comes to aging, “good fats, or omegas, have so many health benefits, it might do more harm than good to cut these out of your diet,” the expert advised. For instance, they enhance mood, reduce cognitive decline, and maybe prevent metabolic disease. Healthy fats like those found in nuts, seeds, seafood, and olive oil are also very satisfying, causing you to consume fewer calories overall. Middle-aged people frequently have more belly fat than their younger counterparts, thus this is advantageous.
Dyc advised being selective about the sources of carbohydrates around middle age.
Our metabolism slows down and hormone production decreases in our 40s and 50s, she explained. “We have more aches and pains than usual, and weight gain is simpler. Fruits and vegetables that are high in nutrients have fibre, antioxidants, vitamins, and minerals that promote healthy ageing.
The licensed dietician and nutrition adviser for the weight-loss app Lasta, Barbara Kovalenko, told us that as individuals become older, they need to make educated decisions about their health.
Both low-fat and low-carb diets, according to Kovalenko, may be able to improve the health of middle-aged and older persons, however, the precise advantages may vary.
In the end, Kovalenko claimed that there is no universally effective diet; what works best for one individual might not work for another. “However, this new research offers insightful information about how making straightforward dietary changes can have favorable effects on overall health outcomes.”
What food experts have to say
According to Lon Ben-Asher MS, RD, a nutritionist, and instructor at Pritikin Longevity Centre, the quality of food consumed as part of a person’s diet has the greatest impact on whether or not that person develops a disease or increases their chance of developing one.
For instance, he claims that the majority of evidence-based research supports adopting an eating pattern that is consistent with a low-carbohydrate or low-fat diet that is centered around high-quality carbohydrates and plant protein sources that are rich in vitamins, minerals, phytonutrients, and dietary fiber as a means of preventing or reducing the risk of chronic diseases like:
- a cardiovascular condition
As examples of foods higher in fiber, he lists the following: peas, potatoes, beans, lentils, and other legumes; muesli; whole grains; and foods low in saturated fats and dietary cholesterol.
According to him, “This way of eating supports good bacteria in the gut microbiome, reducing inflammation throughout the body.” Ben-Asher continues by saying that this is advantageous for maintaining a healthy weight as well as for the brain.
According to a nutritionist and author of “Skinny Liver,” Kristin Kirkpatrick, MS, RDN, while she has many patients who have successfully managed their non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes by following moderate- and low-carb dietary patterns, the most crucial aspect of any dietary pattern is making sure it contains lots of vegetables, protein, and low-glycemic foods.
She adds that it’s crucial to make sure your diet includes good fats like olive oil and nuts because they frequently form the basis of studies on healthy diets.
