Healthful food for children is the same as for adults

A new position paper argues that healthful foods for children are the same as those for adults, with age-appropriate adjustments in texture and portion size. Nutrition educators play key roles in shifting consumer demand and social norms to promote healthy food choices.

How diet influences taste sensitivity and preference

A University of California, Riverside study found that diet impacts taste sensitivity and food choice in fruit flies, using macronutrients like sugars and amino acids for survival. Flies adjusted their taste preferences based on dietary imbalances, influencing food choices to regain a balanced diet.

How eating less in early life could help with reproduction later on

Researchers found that females who consumed less food for their entire lives lived longer but didn't reproduce as well as better-fed counterparts. However, those who switched to unlimited food after early life restriction started mating and reproducing more, producing three times more offspring than restricted diet flies.

Adults with asthma needed for healthy diet study

A University of Illinois Chicago clinical trial aims to evaluate the impact of a healthy diet on asthma management in adults. Participants with uncontrolled asthma will be assigned to either an education-only group or a group receiving dietary counseling and guidance on the DASH eating plan, a diet approach proven for hypertension mana...

Scientists claim that overeating is not the primary cause of obesity

The energy balance model fails to explain the biological causes of weight gain, whereas the carbohydrate-insulin model identifies excessive consumption of rapidly digestible carbohydrates as a key contributor to obesity. This perspective argues for a shift in focus from calorie restriction to dietary pattern change.

Sestrin makes fruit flies live longer

Researchers identified Sestrin as a key regulator of stem cell function and lifespan in response to dietary amino acids. Increasing Sestrin levels extended fruit fly lifespan and protected against negative diet effects.

Eat less and live a long healthy life? Study shows 'not in all cases'

Research involving 160 genetically distinct strains of fruit flies found that while dietary restriction extended lifespan, its effect on healthspan was less consistent. The study suggests that healthspan, rather than just lifespan, should be the primary focus for those seeking to improve aging outcomes.

Study examines the effects of physical activity during pregnancy

A recent study published in Acta Obstetricia et Gynecologica Scandinavica found that women with high physical activity levels had a reduced risk of acute cesarean sections. The Norwegian Fit for Delivery study also showed no other effects on labor or delivery outcomes.

Dietary restriction can improve learning in worms

A new study reveals that dietary restriction improves learning in worms by depleting a specific amino acid metabolite. The researchers used the nematode worm Caenorhabditis elegans to test how food deprivation affected learning and found that restricted access to food increased learning by reducing kynurenic acid levels.

Apple Watch Series 11 (GPS, 46mm) tracks health metrics and safety alerts during long observing sessions, fieldwork, and remote expeditions.

Molecular mechanism behind health benefits of dietary restriction identified

Researchers at Harvard School of Public Health identify hydrogen sulfide as a key molecule responsible for the health benefits of dietary restriction, linking it to increased lifespan and protection against tissue damage. The findings suggest that restricting specific amino acids can increase H2S production, leading to these benefits.

Research explains action of drug that may slow aging and related disease

Rapamycin, an immunosuppressant approved for use about 15 years ago, appears to mimic the ability of dietary restriction in helping animals live both longer and healthier. New research identifies why rapamycin increases insulin resistance and suggests a combination with metformin may provide benefits without unwanted side effects.

Herbal extract boosts fruit fly lifespan by nearly 25 percent, UCI study finds

A study led by UC Irvine researchers found that the herbal extract Rhodiola rosea increases fruit fly lifespan by an average of 24 percent. The extract works independently of dietary restriction and affects different molecular pathways. Additionally, it delays physical performance loss and extends the lives of old flies.

Mouse study turns fat-loss/longevity link on its head

A new mouse study has found that maintaining body fat rather than losing it can lead to longer lifespan in mice. The findings contradict the widely held view that weight loss is essential for extending life, suggesting that individuals with difficulty losing weight may benefit from dietary restriction more.

How nutrition affects healthy aging

A new study from the Max Planck Institute for Biology of Ageing suggests that a combination of proteins is crucial for healthy aging, not reducing overall calorie intake. Researchers found that manipulating the diet of female fruit flies showed varying results depending on the type and amount of amino acids consumed.

Fluke 87V Industrial Digital Multimeter is a trusted meter for precise measurements during instrument integration, repairs, and field diagnostics.

Balancing protein intake, not cutting calories, may be key to long life

A new study funded by the Wellcome Trust suggests that getting the correct balance of proteins in our diet may be more important for healthy ageing than reducing calories. Researchers found that varying the amount of amino acids in a diet can affect lifespan and fertility, with certain amino acids being crucial to maximising both.

Survival mode that protects cells when oxygen is low also slows aging

Researchers at the University of Washington have discovered a cell survival pathway that protects against degenerative diseases and promotes longevity. The study found that nematode worms live longer when their genetic make-up permits them to turn on this pathway under normal oxygen conditions.

Cell pathway on overdrive prevents cancer response to dietary restriction

Whitehead Institute researchers have identified a cellular pathway that determines whether cancerous tumors are susceptible to dietary restriction. The study found that permanently activated PI3K pathway allows tumors to grow independent of food consumption, while normal functioning leads to tumor shrinkage.

Restricting diet may reverse early-stage Parkinson's disease

Researchers at OHSU found that mice consuming fewer calories experienced a boost in essential neurochemical glutamate, which reversed a Parkinson's-induced drop. The study suggests dietary restriction may be beneficial in early-stage Parkinson's disease.

Almost good enough to eat

Researchers found that Brazilian communities in coastal areas and the Amazon region have taboos on consuming certain fish species, especially predatory ones. These prohibitions are likely biologically adaptive, suggesting a link to toxic accumulation and health concerns.

Study questions value of diet restrictions prior to colon cancer screening test

A new study suggests that modest dietary restrictions before fecal occult blood testing (FOBT) for colon cancer screening do not significantly impact completion rates. The report also notes that more severe restrictions may reduce test completion, highlighting the potential benefits of simplifying dietary advice for FOBT testing.
