We saw similar high ADH-1 activity levels in people undergoing dietary restriction or treated with an anti-aging drug called rapamycin.

This finding suggests there may be a common mechanism underlying healthy aging across species, with ADH-1 at its core. We hypothesized that elevated ADH-1 activity promotes health in old age by decreasing harmful levels of glycerol.

Supporting this hypothesis were two critical observations. By contrast, animals genetically modified to boost levels of the glycerol-busting enzyme ADH-1 had low glycerol levels and remained lean and healthy with longer lives, even on unrestricted diets. The simple molecular structure and wealth of research on ADH-1 make it an attractive target for developing drugs that boost its activity.

Anti-aging research generates both excitement and debate. On the one hand, the benefits of healthy aging are clear. On the other hand, extending life span through healthier aging will likely introduce new societal challenges.

If life spans extending to years become the norm, social structures , including retirement ages and economic models, will need to evolve to accommodate an aging population. Legal and social frameworks regarding the elderly and family care may need revision.

During Dr. The treatment worked, effectively shrinking the tumors, but when the researchers repeated the experiments in older rodents, the drug was no longer effective. The realization that age is the root cause of many diseases prompted me to switch fields from cancer biology to aging.

Elderly people are highly prone to frailty, cardiovascular disease, cancer, arthritis, neurodegeneration and other maladies.

Exactly why age makes people more susceptible to these disorders is not yet clear, but recent research suggests that age-related diseases are often preceded by weight loss. In a new study, published recently in Science Advances , Gurkar and her team used a grain-of-sand-sized worm called Caenorhabditis elegans to show that DNA damage — a hallmark of aging — rewires metabolism, triggering breakdown of fat deposits and production of inflammatory compounds that drive age-related disorders.

But with age, our DNA repair pathways become less efficient, and damage accumulates. To understand how persistent DNA damage drives aging, Gurkar and her team used C. elegans shares many cellular features and molecular pathways with mammals, making insights potentially relevant to humans. The researchers compared normal C.

Nonetheless, research in recent years suggests that the function of our fat tissue, or adipose tissue, is central to why our bodies decay with age, and strongly linked to human diseases like diabetes 2, cancer as obesity often develop and fat cells undergo functional changes as we get older.

However, in aand men 65 years or Fts a recent study do not find difference for lean mass between 0. The an of the post-prandial protein synthesis nad due to Gut health and performance elevation qging the anabolic threshold in the elderly.

This threshold depends from the aminoacidemia particularly from the leucinemia Katsanos et al. The elevation of the threshold is due to the splanchnic sequestrations of amino acids in the liver and the intestine, leading to a lesser bioavailability of the amino acids and particularly of leucine for the protein synthesis.

The balance between protein anabolism and catabolism may also be influenced by other factors, physiological factors or not. The anabolism is altered by the insulin resistance, the reduction of anabolic hormones testosterone, growth hormone, IGF1the vitamin D deficiency, the physical inactivity, the mitochondrial dysfunction and the inflammatory process.

Catabolism may be increased by aggressions and tissue losses wounds, burns slough, ulcers, fractures, cicatrisation…or by an excess of physical activity…. So, not only quantitative intake but also qualitative aspects are important for the protein synthesis.

In order to exceed the anabolic threshold, fast proteins which increase more the aminoacidemia are specifically of interest. It is well-known that lactoserum proteins are fast proteins Boirie et al.

Energy intakes and protein metabolism are linked. It is well established that it exists a sparing nitrogen effect of carbohydrates and then of caloric intakes.

It is why in overweight elderly subjects, any energy reduction is always accompanied by a lean mass loss, in absolute or relative value, even if it is associated by exercise Weinheimer et al.

The only one interventional study with a long duration restrictive diet in human has shown a weight loss and a general health alteration Le Bourg, It must not be smaller because it is necessary to maintain recommended essential fatty acid allowances.

Saturated fatty acids particularly from dairy source intake must be sufficient in order to maintain a sufficient intake of myristic acid Jan et al. Moreover, if the saturated fatty acid intake is too low, it could facilitate alpha linolenic acid β oxidation.

In reality, it is necessary to maintain simultaneously sufficient intakes of alphalinolenic acid as a precursor of longer fatty acids because there is a decrease of the desaturases activity with age and sufficient intakes of long chain omega 3 fatty acids EPA and mainly DHA : indeed DHA is a major fatty acid for structural and functional retina Souied et al.

There are no specific requirements for carbohydrates in comparison with younger adults. Their consumption is fundamental for the nitrogen balance. The restrictive diets are negative for maintaining the lean mass. The quality of the carbohydrate intakes is also important to take into account.

A recent prospective study has shown that a high glycemic index diet and a high glycemic load are associated to a higher risk of osteoporotic fractures García-Gavilán et al.

Another study has found an association between free sugars and frailty Laclaustra et al. Calcium and vitamin D intakes are of great importance. Many studies show that a small calcium or a small intake of dairy products is associated with a higher risk of osteopenia and fractures Prentice, ; Fung et al.

For instance in the Melbourne Collaborative Cohort Study Khan et al. Although previous studies have demonstrated the efficacy of a vitamin D and calcium supplementation on the fracture incidence in home resident elderly subjects Chapuy et al. The issue of the dose is raised in that paper since there is probably no benefit to high and spaced doses of vitamin D.

Moreover, supplementation should be given to vitamin D deficient patients, who have a reduced muscle function and walk speed. It is well-known that this last parameter is a good survival marker in the elderly Studenski et al.

All these data show that the continuation of a physical activity is the best way for maintaining sufficient energy intake in order to allow the achievement and the coverage of the non-energetic requirements micronutrients mainly if the nutritional density is not so high.

Moreover, this allows to keep a stable weight and a good lean body mass. Many studies have shown that in the elderly a moderate overweight is associated with a lesser mortality Stevens et al.

Other studies have shown a higher post-surgery mortality for a small body mass index BMI compared to a higher BMI Koster et al. A prospective study has demonstrated that a weight loss in elderly subjects with metabolic abnormalities was associated with an increase of mortality Dong et al.

Similarly, a low muscle strength increases mortality, whatever the weight confirming the major role of the muscle mass. The negative role of sarcopenia in obesity has been proven on mortality as soon as Prado et al.

Obesity with sarcopenia is the most insidious form of sarcopenia with its negative consequences on physical incapacity Baumgartner, and on functional disability Baumgartner et al. So it is fundamental to maintain stable weight in older subjects with normal weight and to obtain sufficient protein and energy intakes and then to maintain a regular physical activity.

In case of obesity in the elderly, it is necessary to screen and prevent sarcopenia. Behind the nutrient intakes, a global or holistic approach is essential. The dietary patterns reflect the dietary complexity.

It includes both the matrix effect Thorning et al. So, for example, it has been shown that a better diet quality with high intake of vegetables, fruits, whole grains, legumes, nuts, dairy products, fish and low intake of sugar-containing beverages is related to larger brain tissue volumes gray matter, white matter, hippocampal volumes Croll et al.

Similarly, the Mediterranean diet is not only associated to a lesser prevalence of the age-related cognitive decline, but it has been shown in randomized controlled trials with a Mediterranean diet a lower risk of low-plasma brain derived neurotrophic factor BDNF which promotes connectivity between neurons Radd-Vagenas et al.

Eat has not only nutritive functions, and nutrient requirements are not the only one dietary needs. Non-nutritive needs are in interaction with the previous. These are hedonic and psychological functions with the eating pleasure and social and relational functions.

They greatly contribute to sufficient dietary intakes and to the coverage of the nutrient requirements. They must be taken into account for an optimized diet. The nutritional requirements during ageing are not so far different from those of younger adults. However, some cautions must be taken, particularly to avoid non-sufficient intakes in proteins and in energy.

Indeed, there is a decrease of the lean mass due to the decrease of the post-prandial protein synthesis, so the protein needs must be increase in order to compensate that.

Moreover, there is a potential vicious circle for the energy balance due to the decrease of the resting metabolism and of the physical activity. Since carbohydrate energy source may improve the protein balance by a nitrogen sparing, it must be also preserve.

Finally, the fatty acids variety is also of consequence for health, mainly the essential fatty acids. A focus must be done on non-energetic nutrients, whose intakes depend on the diet variety and the nutritional density. No food groups must be removed, particularly fish, meat and dairy products for omega 3 fatty acids, proteins, iron, and calcium.

DZNE > Fats influence the speed of aging

The U. Department of Agriculture provides nutrition information for older adults to promote healthy eating and reduce disease risk and tips to manage changes that affect appetite and eating with age. A healthier eating pattern can be achieved and suggestions include 1 enjoying a variety of foods from each food group; 2 ensuring adequate protein intake throughout the day, and adding seafood, dairy, beans, peas, or lentils to meals; 3 adding sliced or chopped fruits and vegetables to meals and snacks; 4 trying foods fortified with vitamin B12 some cereals ; 5 reducing sodium intake by seasoning foods with herbs and citrus; and 6 drinking plenty of water throughout the day to maintain hydration.

Meal planning and understanding food patterns may aid older adults in their understanding of healthy eating. For research purposes, measurement of resting metabolic RMR and activity estimates can be used to help establish individualized dietary recommendations to develop an optimal weight and energy control program.

RMR is defined as the amount of energy expended by a person in a resting state under postabsorptive and thermoneutral conditions. RMR makes up the largest component percent of total daily energy expenditure, which also is composed of the thermic effect of meals TEM 10 percent and the thermic effect of physical activity typically percent but may be much higher in highly active individuals.

The major factor determining RMR is fat-free mass FFM; the body's water, bone, organs, and muscle content ; whereby FFM accounts for percent of the variance in RMR. Age accounts for up to 14 percent of the variance in RMR, and a 2 percent decrease in RMR per decade is observed throughout adulthood.

Thus, although aging affects metabolism, dietary intake and healthy eating together with physical activity can help maintain ideal body weight with aging. Research at the Baltimore VA Medical Center is investigating resting metabolism, weight loss and weight gain, and nutritional interventions in aging populations.

Free radicals are unstable molecules created as a byproduct of normal cell functioning. They can also form in response to stressors from the external environment, such as ultraviolet UV light or tobacco smoke.

You usually get antioxidants through your diet — like from green tea Green tea is particularly high in antioxidants called polyphenols. The polyphenols found in green tea may help reduce external skin aging — from environmental stressors such as the sun and pollution — by scavenging free radicals before they damage the skin 19 , In fact, many skin care products contain green tea extract for its antioxidant and antiaging properties.

However, more research is needed before green tea products can be recommended to reduce skin aging 19 , That said, consuming a diet high in antioxidants is associated with a reduced risk of chronic disease and healthier skin.

And drinking green tea can be a great way to get more antioxidants into your diet Green tea has strong antioxidant properties. As such, it may help protect your skin against free radical damage that can occur as a result of external factors like pollution or sunlight.

That said, more research is needed. Fatty fish is a highly nutritious food that can promote healthy skin. Its long-chain omega-3 fats are beneficial against heart disease, inflammation, and many other issues Furthermore, research has shown that omega-3 fatty acids are linked to a strong skin barrier and may help decrease inflammation that damages the skin First, it contains a carotenoid antioxidant called astaxanthin, which is responsible for the pink color of salmon In one study, people with sun-damaged skin consumed a combination of astaxanthin and collagen for 12 weeks.

As a result, they experienced significant improvements in skin elasticity and hydration. Plus, salmon and other fatty fish are high in protein , which is important to eat so your body can produce collagen and elastin. Eating protein also promotes wound healing 24 , 26 , Finally, fish is high in selenium.

This mineral and antioxidant plays a role in DNA synthesis and repair and may help reduce and prevent skin damage from UV light. Having adequate levels in the body may reduce the severity of skin diseases like psoriasis 24 , Fatty fish, such as salmon, are high in omega-3s, protein, selenium, and astaxanthin, which are all associated with healthier skin.

Dark chocolate is a rich source of polyphenols, which act as antioxidants in the body. In particular, it contains flavanols, which are linked to numerous health benefits, such as a lower risk of 29 , 30 , 31 :. In one high quality week study, participants that consumed a flavanol-rich cocoa beverage experienced significant improvements in skin elasticity and facial wrinkles compared with those in the control group While these results are promising, other studies have not observed that dark chocolate offers benefits for skin appearance or aging 33 , Remember, the higher the cocoa content, the higher the flavanol content.

Dark chocolate contains flavanols that act as antioxidants in the body. Some preliminary research suggests it may improve skin health, though more research is needed. They contain antioxidants, which help reduce the risk of heart disease, cataracts, and certain cancers 35 , 36 , 37 , Many vegetables are also high in carotenoids, like beta carotene and lycopene.

Many vegetables are also rich in vitamin C , which is a potent antioxidant. Vitamin C also plays a crucial role in collagen production. Collagen is a key building block of the skin, but its production begins to decline after the age of 25 21 , Vegetables with the highest vitamin C content include leafy greens, bell peppers, tomatoes, and broccoli.

Vegetables are rich in antioxidants that can help protect your skin from sun damage and help support healthy skin renewal. Flax seeds offer impressive health benefits. They contain lignans, which are a type of polyphenol that has antioxidant effects and may lower your risk of developing a chronic disease, such as heart disease and breast cancer They are also a great source of an omega-3 fatty acid called alpha-linolenic acid ALA.

Consuming a diet rich in omega-3 fats helps support a healthy skin membrane by helping your skin stay hydrated and plump 44 , In high quality studies from and , women who consumed flax seeds or flax oil for 12 weeks showed increased hydration and smoother skin.

However, newer research is needed 46 , Flaxseeds contain types of antioxidants known as lignans, which help fight free radicals in the body. Like most fruits, pomegranates are full of healthy nutrients. Some human and animal studies suggest that the antioxidants found in pomegranates may also help support healthy skin aging by decreasing UV skin damage and brown spots caused by sun exposure 50 , Though more research is needed, pomegranate seeds and their juice can provide a quick, nutritious source of antioxidants in the diet.

Pomegranates are rich in antioxidants that may help with skin repair and protect the skin against sun-related damage. Avocados are rich in heart-healthy fats, fiber, and several vitamins and minerals that are essential for health 52 , Their high content of monounsaturated fat may help promote healthy skin by supporting a healthy skin membrane, while their high antioxidant content may fight free radicals that damage and age the skin For example, one study showed that a diet rich in plant-based fats was linked to better skin health in older adults Considering the delicious taste and versatility of avocados, adding them to your diet is an easy way to get in extra nutrition for healthy skin.

Avocados are rich in monounsaturated fats and antioxidants, which help support a healthy skin membrane and prevent free radical damage that leads to aging.

Tomatoes provide many impressive health benefits, several of which can be attributed to their high lycopene content. Lycopene is a type of carotenoid that gives tomatoes their red color. It also acts as an antioxidant to help reduce the risk of chronic disease 55 , Studies in human skin samples show that lycopene may also provide a small amount of protection from the damaging rays of the sun.

However, this protection is significantly lower than using sunscreen 40 , In one study, women who drank an antioxidant-rich beverage containing lycopene, soy isoflavones, fish oil, and vitamins C and E every day had a measurable decrease in wrinkle depth after 15 weeks However, the study cannot directly tie lycopene to these skin benefits, as the beverage contained several other ingredients As we age, our body begins to break down collagen and produces it less effectively.
