Is your teenager skipping breakfast? Why is that happening and what can you do? As per the data from the Centers for Disease Control and Prevention (CDC), which surveyed adolescent health and well-being found that 1 in 4 students in high school ate breakfast, which means 3 in 4 high school students are not eating their breakfast. This data is as per the 2023 survey.

What Did The Study Intend?

The report describes a 10-year long trend and also recent changes among the two years. The study delved deeper into adolescents' dietary, physical activity and sleep behaviors. The study is also based on a national youth risk behavior survey of a representative sample of students from grade nine to 12.

What Did The Study Find?

The study found that while high school students drank slightly less soda and sports drinks and consumed more water, other healthy eating habits declined. In 2023, only 27% of students ate breakfast every day in the past week. The numbers were even lower for female students, with just 22% eating breakfast daily, compared to 32% of male students. Boys were also more likely to eat fruits and vegetables daily and drink water at least three times a day. Poor mental health and lack of physical activity have also been linked to skipping breakfast.

The other findings included a survey across 10-year period, where a decrease in the percentage of students eating fruits from 65% to 55%, eating vegetables, from 61% to 58%, and having breakfast daily from 38% to 27% was noted.

However, there was a positive trend among this, which was in children drinking plain water at least three times a day, which increased from 49% to 54% from when the survey began in 2015.. There were fewer students who also said that they drank soda in 2023 than in 2013. On an average, in 2013, around 22% students avoided soda, whereas in 2023, 31% students avoided it.

The report also emphasized that a healthy diet, along with daily physical activity and sufficient sleep further contributes to a healthy lifestyle. “The 10-year trends from 2013 to 2023 also show a decline in healthy dietary, physical activity, and sleep behaviors,” the survey reported.

Why Do High School Students Skip Breakfast?

While there is no one straightforward answer to it, psychologists and those who study children, believe that for many high school going kids, it is the easiest time to skip a meal. This is because they are caught between rushing to school, or not just that hungry in the morning. So for them, to sit down to have a breakfast may seem hassle and something they would have to take time out from their busy schedule. They at this age also prioritize their extra-curricular activities.

There has also been a shift in their circadian rhythm, and most teens cannot fall asleep before 11 pm, or even at midnight. Which means they wake up tired and struggle to do things right in the morning, which is why they choose to skip breakfast or give extra minutes to any other activities.

There is of course another, more popular reason, to lose weight. While experts and studies, like the one published in the Journal of Nutrition that found skipping breakfast leads to higher levels of hunger hormones, the students still feel the need to do this. However, it could lead to a slow metabolism, prompt the body to conserve energy and burn fewer calories, weight gain and deprive yo off the essential nutrients like calcium, iron, and vitamin D.

Without a morning breakfast, your blood sugar might drop too, which can increase irritability and stress, along with including the risk of depression in teenage.

Research suggests that disruptions in rapid eye movement (REM) sleep, during which we dream, consolidate memory, and process emotions, could be among the earliest biological signs of Alzheimer's disease.

Scientists now believe that changes in sleep are not just a consequence of Alzheimer's, but may actually appear years before primary cognitive symptoms emerge.

What The Study Found?

The study, published in Alzheimer's & Dementia, studied 128 older adults, including people with Alzheimer's disease, mild cognitive impairment (MCI), and cognitively healthy individuals.

Participants underwent overnight polysomnography, the gold standard sleep test that records brain activity, breathing, heart rate, eye movements, and muscle activity during sleep.

Researchers discovered that participants who took significantly longer to enter REM sleep, known as REM sleep latency, were more likely to have Alzheimer's disease.

These individuals also showed:

• Higher levels of amyloid-beta, the protein that forms plaques in Alzheimer's disease.
• Increased tau protein, another hallmark of the disease that damages brain cells.
• Lower levels of brain-derived neurotrophic factor (BDNF), a protein essential for learning, memory, and maintaining healthy neurons.

Importance Of REM Sleep

Scientists believe REM sleep also supports the brain's "cleaning system," helping remove waste products that accumulate during the day.

When REM sleep is delayed or disrupted, this process may become less efficient, allowing toxic proteins like amyloid-beta to build up over time.

According to Dr. Yue Leng, associate professor in the Department of Psychiatry and Behavioral Sciences at the University of California, San Francisco and one of the study's authors: "Delayed REM sleep may disrupt the brain's ability to consolidate memories by interfering with the process that converts recent experiences into long-term memories. If this is insufficient because REM sleep is delayed or shortened, it could increase the stress hormone cortisol. This may impair the brain's hippocampus, a critical structure for memory consolidation."

Commenting on the findings, Dr. Jocelyn Cheng, neurologist and Senior Director of Neuroscience Clinical Research at Eisai U.S., said:

"The relationship may be bidirectional. Delayed REM may contribute to Alzheimer's-type changes, and/or Alzheimer's itself may result in prolonged REM latency."

Sleep Problems Appear Early

The new findings offer a possible biological explanation. Researchers suggest that the accumulation of amyloid may interfere with the brain's internal clock and its ability to regulate normal sleep cycles, creating a vicious cycle where poor sleep accelerates brain changes linked to Alzheimer's.

Researchers say future studies should examine whether improving REM sleep through better sleep hygiene or treatment of conditions such as sleep apnea could help slow or delay Alzheimer's-related brain changes.

Experts recommend maintaining a regular sleep schedule, limiting alcohol before bedtime, reducing evening screen exposure, and seeking medical evaluation for persistent sleep disorders.

While the US is seeing one of its largest-ever Cyclospora outbreaks, with Michigan reporting more than 6,500 cases and several hospitalizations, Health and Human Services Secretary Robert F. Kennedy Jr. said the multi-state cyclosporiasis outbreak is "under control."

"We do have the outbreak under control," Kennedy told ABC News. "We have an extensive forensics, epidemiological forensics, and we've identified the source of the outbreak. We and the companies that are involved have implemented a recall."

The US Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) have linked the outbreak, which has sickened at least 1,600 people across five states, to shredded iceberg lettuce served at some Taco Bell locations. The lettuce was supplied by Taylor Farms and sourced from central Mexico.

Michigan Cases Continue To Rise

The Michigan Department of Health and Human Services reported 6,571 cases in the state as of July 21, up by 423 from the 6,148 cases reported a day earlier. The state's patients include a woman who said she remained ill for several days after becoming infected.

As of July 16, 102 people had been hospitalized, more than double the 44 hospitalizations reported the previous week.

Lettuce Recall

Taylor Farms has voluntarily recalled dozens of lettuce products across 27 states and said it will not source iceberg lettuce from central Mexico for "the rest of the growing season."

Health officials are continuing to investigate additional cases and any other potential sources of infection. So far, no other sources have been identified for the domestically acquired infections reported in 29 other states.

Taylor Farms also said on social media that none of its Taylor Farms-branded salad kits are linked to the outbreak. Most of the recalled lettuce was sold in large bags to food-service operations, including restaurants, with many products blended with romaine lettuce.

Media reports also said several companies have begun removing affected products from stores and supply chains, including:

• Walmart
• Sysco
• US Foods
• Jack in the Box
• Taco Bell

What Is Cyclospora cayetanensis?

Cyclospora cayetanensis is a microscopic parasite that causes cyclosporiasis, a foodborne intestinal illness. People become infected by consuming contaminated food or water.

The infection typically causes watery diarrhea and other digestive symptoms. While many cases are mild, the illness can last for weeks or even months if left untreated. Doctors usually treat the infection with antibiotics.

People with weakened immune systems, including those with HIV/AIDS, cancer, or other conditions that affect immunity, are at greater risk of developing severe illness.

Symptoms Of Cyclospora Infection

Symptoms usually appear about one week after consuming contaminated food or water and may include:

• Watery or explosive diarrhea
• Loss of appetite
• Bloating and gas
• Fatigue
• Low-grade fever
• Nausea
• Stomach cramps
• Vomiting

How To Reduce Your Risk

Health officials recommend:

• Avoid eating shredded iceberg lettuce linked to the recall.
• Wash all fresh fruits and vegetables thoroughly under clean running water, even if they are labeled pre-washed.
• Follow safe food-handling practices.
• Stay updated on food recalls and outbreak alerts.
• Contact a healthcare provider if symptoms develop.

Experts also recommend choosing whole heads of lettuce instead of bagged greens. Remove the outer leaves, wash the inner leaves thoroughly under running water, and cook produce whenever possible, as heat is the most effective way to kill Cyclospora.

Even as India has vaccinated more than 5.2 million girls against the Human Papillomavirus (HPV), the Delhi High Court on Tuesday sought responses from the Centre and the Indian Council of Medical Research (ICMR) over the nationwide rollout of the cervical cancer vaccine, Gardasil, following allegations that it is being introduced without adequate study.

The court issued notice on a Public Interest Litigation (PIL) challenging the proposed administration of the vaccine to adolescent girls under the Universal Immunization Program (UIP).

According to the petition, the vaccination program is being implemented without ensuring informed parental consent and adequate scientific safeguards, Live Law reported.

A Division Bench of Chief Justice Devendra Kumar Upadhyaya and Justice Tejas Karia described the matter as "extremely important."

According to the Centre, 52,10,302 girls across the country have received the HPV vaccine under the nationwide campaign launched by Prime Minister Narendra Modi in February. The figures were shared in Parliament during the ongoing Monsoon Session.

Court Seeks Government's Response

The Bench also asked Additional Solicitor General Chetan Sharma to assist the court in the matter.

"Mr Sharma, very important issue. Vaccination is a good scheme, but if there are some adverse consequences, we will have to be very cautious. Seek instructions from the Ministry. Ask some officer to come and brief you. Someone who is in charge of all this should come and brief you, and ensure that someone from the drug control organisation also comes and briefs you," the Court remarked.

The judges clarified that they were not questioning the government's intentions, but emphasized that the issue affects the health of millions of adolescent girls and therefore warrants careful scrutiny.

"We have to tread a very cautious path," the Bench observed.

What Does the PIL Allege?

The PIL, filed by gynecologist Dr. Sujata Mittal and fitness influencer Jitendra Chouksey, raises concerns about the data, efficacy and necessity of the Gardasil vaccine.

The petition claims that vaccination drives are being conducted in schools and that frontline health workers, including ASHA workers, have been assigned enrolment targets. It alleges that this has, in some instances, resulted in undue pressure on adolescent girls to get vaccinated, Bar and Bench reported.

The petitioners also cited the case of a 14-year-old girl from Tamil Nadu who allegedly developed severe neurological complications—including paralysis-like weakness, loss of voice and impaired vision—days after receiving the vaccine in March 2026.

The PIL further refers to similar reported incidents in Gwalior and Bihar, questioning whether adequate vaccine safety monitoring and surveillance mechanisms are in place.

Why HPV Vaccination Matters

The national program uses Gardasil, a quadrivalent HPV vaccine that protects against HPV types 16 and 18, which are responsible for most cervical cancers, as well as types 6 and 11, which cause genital warts.

According to the government, Gardasil has been licensed for use in India since 2008. The nationwide rollout follows recommendations from the World Health Organization (WHO) and approvals by the National Technical Advisory Group on Immunization (NTAGI).

Human Papillomavirus (HPV) is the most common sexually transmitted infection worldwide. While many infections clear on their own, persistent infection with high-risk HPV strains can lead to cervical, anal, throat and penile cancers. HPV vaccination is widely recommended to help prevent cervical cancer, particularly when administered before exposure to the virus.

The High Court has scheduled the next hearing in the matter for July 29.
