Avocados have been shown to aid sleep and lower the risk of heart disease

A new study suggests eating one avocado a day can positively impact sleep.
Participants who consumed one avocado daily for six months reported better sleep compared to those who ate fewer than two avocados per month.
The researchers also looked at the effect this had on cardiovascular health, as previous studies have shown insufficient or disrupted sleep can increase the risk of 'silent killer' condition heart disease.
In the study, 969 American adults took part, and all had elevated waist circumstance - a cardiovascular risk factor.
Participants were picked at random to either consume one avocado a day or less than two avocados per month, while continuing their usual diet for six months.
Their cardiovascular health was then assessed using the AHA's Life Essential 8 tool, which identifies diet quality, physical activity, nicotine exposure, sleep, body weight, blood pressure, blood lipids, and blood glucose as leading behaviours and factors that when improved can lead to better health outcomes.
Daily avocado intake was linked to improved diet quality, blood lipids, and sleep health.
But no other significant effects were found for the other Life's Essential 8 components.
The study wasn't originally designed to examine sleep as a primary outcome, but bridges the gap for further research into how the nutrients in avocados may support aspects of cardiovascular health.
Avocados contain a number of nutrients that play a role in sleep.
Five best stretches to improve sleep
They're a good source of tryptophan, an essential amino acid that plays a role in serotonin production, which can impact mood and sleep.
They also contain folate, which is involved in melatonin production, and magnesium, which aids in muscle relaxation, further supporting sleep regulation.
And their magnesium content can support muscle relaxation and stabilise blood sugar levels.
Additionally, the combination of fibre and monounsaturated fats in avocados contributes to their beneficial impact on cardiovascular health.
Fibre can help reduce cholesterol levels and improve blood sugar control, both important factors in heart health.
And monounsaturated fats, a type of healthy fat, can help lower LDL ("bad") cholesterol levels and raise HDL ("good") cholesterol levels.

Sleep is considered as important as exercise and nutrition

If you're struggling to sleep or think you have a sleep disorder like insomnia, the NHS recommends trying the following tips:
go to bed and wake up at the same time every day
relax at least one hour before bed, for example, take a bath or read a book
make sure your bedroom is dark and quiet – use curtains, blinds, an eye mask or ear plugs if needed
exercise regularly during the day
make sure your mattress, pillows and covers are comfortable
You should avoid:
smoking or drinking alcohol, tea or coffee at least six hours before going to bed
eating a big meal late at night
exercising at least four hours before bed
watching television or use devices, like smartphones, right before going to bed, because the blue light makes you more awake
napping during the day
driving when you feel sleepy
sleeping in after a bad night's sleep and stick to your regular sleeping hours instead
If you've had trouble sleeping for months, speak to your GP.
Avocados can be bought for as little as 75p from Sainsbury's.

Two killed including school cook, 62, after eating poisonous guacamole as 2 children recover in hospital
It comes amid mounting fears around food safety KILLER GUAC Two killed including school cook, 62, after eating poisonous guacamole as 2 children recover in hospital TWO people have died and two children are recovering in hospital after several people were poisoned by a toxic batch of guacamole. The fatally contaminated avocado dip was served up to unsuspecting customers at a food festival before they showed signs of botulism. 5 Valeria Sollai, a 62-year-old school cook, reportedly died after eating contaminated guacamole Credit: Facebook 5 Roberta Pitzalis, 38, also died after eating the avocado dip Credit: Facebook Advertisement 5 Two women died and two children were hospitalised after eating toxic guacamole (stock) Credit: Getty School cook Valeria Sollai, 62, is said to have eaten the guacamole and then was rushed to hospital. But she died on Monday after spending weeks on life support. Roberta Pitzalis, 38, also ate the same batch of guacamole at the festival in Sardinia - before dying on August 8. Advertisement An autopsy confirmed Roberta died from a combination of botulism poisoning and pneumonia. Several others required hospital treatment following the horrifying ordeal at the Fiesta Latina festival. The food event took place in Monserrato, in Cagliari, between July 22-24. One boy and one girl, aged 11 and 14 respectively, remain in hospital and are reported to have eaten from the same batch of guacamole. Advertisement A post-mortem for Valeria is set to take place. She showed signs of recovery before suffering a relapse and tragically dying. Her cousin Gianni Milia said: "It's absurd that someone goes out for a relaxing evening, goes to a party, eats a sandwich and ends up in the hospital. Woman, 45, becomes second person to die after eating 'toxic broccoli' as 17 others poisoned as veg recalled across Italy "She was with her sisters, they all ate the same sandwich, but only she fell ill." She added: "They were celebrating their older sister's discharge from the hospital. A party turned into a tragedy." Advertisement Describing Valeria, Monserrato mayor Tomaso Locci said: 'She gave so much for our children. "The news saddens us deeply. We will be present at the funeral as a community, as we were for Roberta Pitzalis, the other victim. "This is a loss that affects us all.' Valeria is survived by her husband, Angelo Aru, and her son Alessandro, a police officer in Campania. In a Facebook post last month, Alessandro spoke about an unnamed patient with 'worsening neurological conditions'. Advertisement He also made a heartbreaking appeal for people to be more careful with street food. He said: "I strongly advise against eating any food sold at street stalls over the next few weeks." The poisoned 14-year-old girl is being treated at Monserrato Policlinico hospital. Meanwhile, the 11-year-old has been flown to Rome's Gemelli Policlinico and is said to be in a serious condition. Botulism: Everything you need to know What Is It? Botulism is a rare but serious illness caused by a toxin produced by the bacterium Clostridium botulinum. It affects the nervous system, leading to muscle paralysis and breathing difficulties. How is it contracted? The illness usually comes from eating food contaminated with the toxin. This often happens due to improper food processing, such as inadequate canning. Symptoms to watch for: Muscle weakness Difficulty breathing Double vision Difficulty swallowing How serious is it? Botulism can be life-threatening. In severe cases, it can cause death, with around 10 per cent of cases being fatal if not treated promptly. Treatment: If you think you are suffering from botulism poisoning, medical attention is crucial. Treatment typically involves antitoxins and supportive care, including breathing assistance if necessary. Prevention: Ensure proper food processing and handling. Avoid consuming home-canned foods if you're unsure about their safety. It comes amid mounting concern over food safety in Italy following similar events across the country. Advertisement Another deadly botulism outbreak was reported in the southern region of Calabria earlier this month. It also comes after two people in Italy died after eating a toxic veggie and sausage sandwich in Italy. More than a dozen people were hospitalised after eating the poisoned sandwiches from a food truck near the town of Diamante in Calabria. Tamara D'Acunto, 45, died shortly after eating the panini made with turnip greens - a vegetable similar to broccoli - last week. Luigi Di Sarno, 52, also died after taking a fatal bite from a sandwich bought from the same vendor. Advertisement In total, 17 other people have so far been hospitalised with food poisoning within 24 to 48 hours of eating the sandwiches. They all showed signs of botulism - which is caused by a toxin that attacks the body's nerves. The illness can lead to muscle paralysis, breathing difficulties and death. It is typically caused by canned, preserved and fermented foods. 5 Two people died after eating contaminated food which gave them botulism Credit: Getty Advertisement

US pediatric organization diverges from CDC in Covid-19 vaccine advisory for children
The American Academy of Pediatrics (AAP) is urging that children as young as six months and up to 23 months old receive the Covid-19 vaccine – a position that diverges from the current federal guidance given by the Trump administration's health agencies. The AAP released its updated childhood immunization schedule, which outlines recommendations for vaccines against Covid-19, influenza and RSV for individuals under 18. 'It differs from recent recommendations of the advisory committee on immunization practices of the CDC, which was overhauled this year and replaced with individuals who have a history of spreading vaccine misinformation,' the organization said in a statement. The announcement follows a decision from health and human services secretary Robert F Kennedy Jr in late May to halt CDC recommendations for healthy children to receive the Covid-19 vaccine. Previously, the CDC advised vaccination for everyone six months and older with the latest available dose. The CDC currently advises that Covid-19 vaccinations for children aged six months through 17 years should be determined through 'shared clinical decision-making'. The AAP recommends vaccination for anyone under 18 who is at higher risk of serious illness from Covid-19, resides in a longterm care or congregate living facility, has not previously been vaccinated, or shares a household with someone at elevated risk. 'The academy has been making pediatric immunization recommendations since the 1930s, that has not changed,' Dr Susan Kressly, president of the AAP, told ABC News. 'But what has changed is that this year, we're doing it in the environment of misinformation, which makes it more important than ever that we provide clear and confident guidance, because the majority of American families really depend on us for this guidance.' AAP says infants and toddlers between six and 23 months face the greatest risk for severe outcomes from Covid-19 and vaccination offers protection against serious illness. Even as medical groups continue to disagree with federal agencies, insurers often base coverage on guidelines from the CDC's advisory committee on immunization practices (ACIP). If ACIP declines to endorse a vaccine, families may have to pay out of pocket, and the shot may not be provided through the federally funded Vaccines for Children program. Kennedy's restructured vaccine panel has maintained support for annual flu shots but voted to limit them to single-dose formulations without the preservative thimerosal. The AAP, however, maintains that the preservative poses no risk and said physicians should administer any approved flu vaccine suitable for the patient.
