Jessica Knurick is a registered dietitian with a PhD who has rapidly emerged as one of the most influential public health voices on social media. With more than 1.1 million followers on Instagram and over 335,000 on TikTok, she is using the same platforms that fueled misinformation to push back with evidence-based content. Her style is simple but powerful. She blends humor, accessible explanations, and scientific accuracy in short videos that debunk myths and highlight where health narratives go wrong.

Her journey into this digital advocacy space was personal. During her first pregnancy in 2019, she noticed scattered but not overwhelming amounts of misleading information targeted at expecting mothers. By the time she had her second child in 2022, the pandemic had amplified conspiratorial and fear-based health content across platforms. What had once been background noise became the dominant message being shown to her feeds. That was when she realized the scale of the problem, and the urgent need for credible counter voices.

Understanding the MAHA Movement

The Make America Healthy Again (MAHA) movement emerged out of a growing distrust in public health institutions. Initially fueled by wellness influencers and conspiracy-laced narratives about toxins, chemicals, and corrupt medical systems, the movement gained a national platform when Robert F. Kennedy Jr. launched his presidential campaign in 2024. Now serving as Secretary of Health and Human Services under Donald Trump, Kennedy and the MAHA agenda are reshaping health policy with their focus on distrust of regulation, vaccines, and science.

MAHA thrives because it taps into genuine frustrations. Rising chronic disease rates, expensive healthcare, and a food system often criticized for prioritizing profits over people’s well-being all resonate with Americans. But where the movement gains attention is in its framing, blaming shadowy corruption, demonizing ingredients like seed oils or food dyes, and questioning the legitimacy of mainstream health guidelines.

The results have been concerning. Falling vaccination rates, for example, contributed to a historic measles outbreak this year. Yet millions of Americans continue to be swayed by MAHA’s polished social media messaging and distrust of traditional experts.

Knurick’s Counter-Narrative Strategy

Knurick does not deny that the US has a chronic disease crisis. She acknowledges that too many people are living with conditions linked to lifestyle and systemic problems. What she challenges is how MAHA leaders explain those problems and the solutions they propose.

Her method is to meet people where they are, on Instagram and TikTok, and arm them with tools to navigate misinformation. In her videos, she often points out logical fallacies, like confusing correlation with causation. She also highlights overlooked factors that evidence shows drive chronic disease: income inequality, lack of access to healthcare, education gaps, and systemic disparities. These social determinants of health are almost entirely absent from MAHA’s messaging.

Knurick also calls out contradictions and financial interests within the MAHA leadership. Many of its most prominent figures run supplement companies or wellness product businesses, financially benefiting from the fear they spread. She argues that if the pharmaceutical and food industries deserve scrutiny for conflicts of interest, so too should the wellness industry, which operates with far less regulation.

Balancing Tone and Reach

One of Knurick’s challenges is tone. She knows that many MAHA supporters are parents, especially mothers, who are genuinely anxious about their children’s health.

These women are vulnerable to fear-based messaging like “Are you poisoning your kids?” which thrives in wellness circles. Being a mother herself, Knurick understands the emotional triggers at play.

Her approach is firm but not condescending. She avoids personal attacks on ordinary supporters, focusing instead on the misinformation itself. While her critiques of Kennedy are sharp, she maintains that her goal is not to mock but to explain. The result has been encouraging.

Many followers who initially came to her page as skeptics admit to being swayed by her evidence-backed explanations.

Still, she recognizes she will not reach everyone. Those deeply loyal to MAHA leadership may tune out. But Knurick’s growing following and steady stream of messages from people who have reconsidered their views suggest her efforts are making a difference.

Rebuilding Trust in Science

Knurick’s larger mission goes beyond countering individual claims. She is working to rebuild a culture of trust in evidence and science. In a world where traditional appeals to authority no longer carry weight, she believes teaching media literacy is essential. By showing people how to spot out-of-context data, manipulated graphs, or exaggerated claims, she hopes to empower her audience to become more discerning consumers of information.

Her efforts are not just about defending institutions but about reframing public health in a way that resonates.

She agrees with MAHA that the system often fails people. Where she differs is in how to fix it. Instead of scapegoating food dyes or dismissing vaccines, she emphasizes systemic reforms, improved access, and real policy solutions.

Why Knurick Matters Now

The battle over health information is no longer confined to medical journals or government press releases. It is happening on TikTok, Instagram, and in the hands of influencers.

By stepping into that arena, Knurick represents a new model for public health communication: expert-led, evidence-driven, but adapted to the realities of the digital age.

As misinformation continues to spread and movements like MAHA reshape national policy, her work is more critical than ever. She is not just correcting false claims but also offering a vision of what a more honest, evidence-based conversation about health could look like.

California made it news for a disease that has no vaccination. This is the human metapneumovirus or the HMPV. While some of the symptoms of this virus are similar to that of any common cold or influenza like cough, fever, nasal congestion or shortness of breath, there are several symptoms that are unique to the disease.

Unique Symptoms Of HMPV - The Virus Without Vaccine

Unlike mild common colds, HMPV often presents with a high-grade fever, particularly in children. Some of the other symptoms also include persistent coughing, including dry or productive and may persist for a long duration.

Furthermore, it could cause wheezing, difficulty in breathing, which could also lead to severe lower respiratory tract illness like bronchiolitis or pneumonia. In children and older adults, it could also cause severe or often fatal bronchiolitis or rapid-onset pneumonia.

In infants, it could also exhibit irritability, poor feeding, or dehydration.

Other symptoms, which could resemble common cold like symptoms are:

• cough
• fever
• sore throat
• runny or stuffy nose
• body ache
• headache

What Is Happening In California?

As per the public database WasterwaterScan Dashboard, high levels of HMPV were detected across Northern California cities. The highest levels were reported in Redwood City, whereas elevated levels were found in San Francisco Bay Area and Napa's Wine Country. What's more dangerous is that this virus is without a vaccine.

The good news is that in other parts of country HMPV remains lower. However, the Centers for Disease Control and Prevention (CDC) noted that data from October 2025 shows the cases are trending up, especially during winter and spring.

Dr. Matthew Binnicker, director of the Clinical Virology Laboratory at Mayo Clinic, as reported by The Independent said, "In the late winter, early spring, it can account for five percent to 10 percent of all the respiratory infections that we diagnose in the United States. So it's definitely out there." Experts explain that other viruses like HMPV or influenza get a chance when COVID is quieter.

What Is HMPV - The Virus Without Vaccine?

HMPV was first discovered in 2001 and is part of the Pneumoviridae family along with the Respiratory syncytial virus (RSV).

HMPV most likely spreads from an infected person to others through:

• the air by coughing and sneezing
• close personal contact, such as touching or shaking hands
• touching objects or surfaces that have the viruses on them, then touching the mouth, nose, or eyes

In the US, HMPV circulates in predictable patterns each year, typically beginning in winter and lasting through spring.

Who Are At Risk Of HMPV?

People at risk include:

• elderly people
• children
• people with comorbidities

"The HMPV is not deadly, and there is no evidence of mortality or a severe transmission rate," former Indian Council of Medical Research (ICMR) scientist, Dr. Raman Gangakhedkar, told IANS, during the virus's outbreak in India in 2025.

“The virus may cause pneumonitis-like illness, but the mortality rates are almost unknown so far. HMPV has a global prevalence of about 4 per cent,” he added.

Smoking has been long recognized as one of the worst habits a person can have, and Dr Jeremy London agrees with this statement. Dr. London, a cardiovascular surgeon, in a recent interview with Mel Robbins revealed that his number one advice as a heart doctor is to avoid smoking.

“I cannot come up with one single thing that does as much damage to every organ in the body as smoking cigarettes. And look, it's incredibly addictive and I know that and I pass no judgment because I know how difficult it is.”

He explained that in his practice he has dealt with chronic smokers for years and still believed that it is the single most dangerous thing one can do to themselves.

How Does Smoking Affect Other Organs?

Emphasizing how this one habit affects all organs in our body, Dr London mentioned the well-known link between lung cancer and smoking.

However, there are many more chronic diseases associated with the rest of the body that can develop due to smoking apart from lung conditions, according to the American Lung Association.

Here is what you should keep an eye out for:

Lung Cancer

Smoking is the leading cause of lung cancer, accounting for nearly 90 percent of all cases. Although medical treatments have improved, the five-year survival rate remains low. Quitting is the most effective way to lower your risk of this deadly disease.

Chronic Obstructive Pulmonary Disease

Other Cancers

Fasting for three hours before bed can significantly improve heart health and reduce the risk of coronary artery disease (CAD) as well as other chronic conditions, an Arteriosclerosis, Thrombosis, and Vascular Biology study suggests.

While many believe that diet plans such as intermittent fasting or time-restricted eating can help reduce their weight, researchers at Northwestern University have found that not eating three hours before going to sleep can reduce overnight blood pressure by nearly four percent, heart rate by five percent and strengthen overall heart rhythms.

This can help reduce overall strain on the heart which lowers risks for conditions like hypertension and CAD. Additionally, the scientists also discovered a drop in blood sugar levels, improved glucose tolerance and insulin sensitivity.

Participants who underwent glucose tests also showed better insulin release which tend to stabilize during the day. Additionally, an improved heart rate also lowered nighttime cortisol, which helped in metabolic balance.

Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine and chief of sleep medicine in the department of neurology at Feinberg and corresponding author said of the results: "It's not only how much and what you eat, but also when you eat relative to sleep that is important for the physiological benefits of time-restricted eating."

The study authors also noted: "Extending overnight fasting duration by three hours in alignment with sleep improved cardiometabolic health in middle-aged/older adults by strengthening coordination between circadian- and sleep-regulated autonomic and metabolic activity.

"This sleep-aligned time-restricted eating approach represents a novel, accessible lifestyle intervention with promising potential for improving cardiometabolic function."

Coronary Artery Disease: The Silent Killer

Despite being as a common heart disease, coronary artery disease (CAD) develops over years and has no clear signs and symptoms apart from a heart attack. The illness begins due to a buildup of fats, cholesterol and other substances known as plaque in and on the artery walls.

Over time, this can cause narrowing or blockage of the coronary arteries and block the supply of oxygen-rich blood to heart which can lead chest pain (angina), shortness of breath and ultimately, heart attacks.

Typically, those above the age of 45, having a biological family member with heart disease, lack of sleep, smoking, consuming saturated fats along with other autoimmune diseases such as lupus and rheumatoid arthritis can increase the risk of developing CAD.

Treatment options may include medicines and surgery. Eating a nutritious diet, getting regular exercise and not smoking can help also prevent CAD and the conditions that can cause it.

Nearly one in 10 Indian adults suffer from CAD and about two million people die from the disease annually. Apart from this, about 18 to 20 million American adults aged 20 and older are also affected about the disease.

Strokes: A Rising Crisis In India

One in seven stroke patients in India are young adults aged below 45 years, with hypertension leading as the major risk factor, according to a study by the Indian Council of Medical Research (ICMR).

The Global Burden of Disease Study 2021 identified hypertension, air pollution, tobacco smoking, high cholesterol, increased salt intake, and diabetes as the leading risk factors of stroke.

Incidence of stroke is increasing significantly in low- and middle-income countries (LMICs), especially in India, due to population growth, aging, and greater exposure to risk factors.
