While no specific diet has been proven to stop MS symptoms or slow the disease’s progression, adopting a healthy lifestyle can significantly enhance one’s quality of life. Experts at UNC Health advocate for a balanced diet rich in vegetables, whole grains, and lean proteins while steering clear of processed foods and excessive salt intake.

The following dietary guidelines can help alleviate fatigue, improve bladder and bowel function, and combat inflammation, thereby promoting overall health.

Incorporate Plenty of Leafy Greens

Although a single diet has not been definitively shown to slow or reverse MS symptoms, research suggests that a nutritious diet can be beneficial. Some specialists recommend a low-fat, high-fiber diet that limits animal products and tropical oils, which may help mitigate the risk of obesity and maintain essential vitamin levels.

Leafy greens play a vital role in a well-rounded diet. They are packed with vitamin C, potassium, and fiber, along with folate, lutein, and zeaxanthin. These nutrients support eye health, cognitive function, and emotional well-being.

Low glycemic foods like leafy greens can assist in maintaining a healthy weight. Consider incorporating a daily salad, steamed greens, or a green smoothie into your meals. It’s wise to avoid monosodium glutamate (MSG), a flavor enhancer that may aggravate MS symptoms.

Emphasize Whole Grains in Your Diet

Consuming a variety of whole grains such as oats, brown rice, and quinoa can enhance fiber intake and stabilize blood sugar levels, which helps prevent fatigue.

Fish rich in omega-3 fatty acids may also play a role in preventing or slowing the progression of MS symptoms. Additionally, vitamin D and calcium supplements can be beneficial. It is advisable to limit saturated fats, which may worsen inflammation and increase the likelihood of MS relapses.

Several dietary approaches exist for individuals with multiple sclerosis, including the Swank diet, which emphasizes reducing saturated fat intake. This diet is based on observations that lower saturated fat consumption correlates with fewer relapses and slower disease progression in MS patients. It also highlights the importance of fruits, vegetables, and olive oil.

Include Fish in Your Meals

Fish and fish oil are excellent sources of omega-3 fatty acids, which have been associated with a reduced risk of developing multiple sclerosis (MS). Recent studies indicate that individuals who consume fish one to three times a week or take daily fish oil supplements experience a 45 percent lower risk of developing MS or clinically isolated syndrome (CIS).

Researchers evaluated the diets of 1,153 participants enrolled in the MS Sunshine Study from Kaiser Permanente Southern California, categorizing them based on their fish consumption. Those with a high intake of fish—defined as eating fish one to three times weekly and taking daily fish oil supplements—exhibited a significant reduction in the risk of developing MS and experiencing a first episode of MS, known as clinically isolated syndrome. These findings support the notion that modifiable risk factors, including smoking and alcohol consumption, may influence the likelihood of developing MS.

Limit Saturated Fat Intake

Numerous claims suggest that specific diets can cure MS, but while these claims lack substantial proof, there is evidence that dietary modifications can positively impact symptoms. One crucial change involves minimizing saturated fat, which can elevate cholesterol levels and contribute to heart disease. A diet low in saturated fat can alleviate symptoms like bladder dysfunction and fatigue.

Simple substitutions, such as replacing cow’s milk with soy, almond, or cashew milk, can help reduce saturated fat intake while still providing calcium and protein. It is also essential to limit sugar, which can exacerbate fatigue and lead to weight gain. Excess weight can further intensify MS-related fatigue. Lastly, reducing salt intake is vital, as it can contribute to hypertension.

Reduce Salt Consumption

Many MS symptoms, including fatigue and bladder issues, can be improved through dietary changes. These adjustments may involve cutting back on salt and sugar, both of which can contribute to MS-related fatigue.

A high-fat, low-carbohydrate diet may help alleviate some symptoms; however, it is advisable to avoid the ketogenic diet, as it can lead to nutrient deficiencies.

Limiting salt intake is also wise, as high salt consumption can elevate blood pressure and negatively affect heart health. Some studies suggest a correlation between high salt intake and increased MS relapses, though other research indicates that reducing salt does not necessarily lessen the duration or severity of these relapses.

Vitamin C, a powerful antioxidant, is abundant in various fruits and vegetables, including bell peppers, kiwis, and broccoli. This essential nutrient plays a vital role in combating free radicals that can damage cells and lead to illness.

Research indicates that high doses of vitamin C can reduce the frequency of colds and shorten their duration. The most significant benefits arise when vitamin C is consumed shortly after the onset of cold symptoms.

Can Vitamin C Alleviate Cold Symptoms?

Many individuals turn to vitamin C supplements when they sense a cold approaching. Available in forms such as juices, cough drops, and teas, vitamin C is believed to lessen the duration of colds and mitigate symptom severity. This nutrient is crucial for the immune system, aiding in the defense against infections and facilitating wound healing.

However, increasing vitamin C intake does not prevent colds and may even exacerbate certain symptoms. Excessive consumption can strain the digestive system and kidneys.

Linus Pauling, a double Nobel Prize laureate, advocated for high doses of vitamin C to ward off colds during the 1970s. Yet, subsequent studies have not substantiated this claim. Research involving the general population has shown that while vitamin C does not prevent colds, it can effectively reduce their duration and severity, particularly in athletes subjected to intense physical exertion or cold environments.

How Much Vitamin C Should You Take for a Cold?

This nutrient acts as a robust antioxidant, preventing cellular damage caused by free radicals, which can lead to cold symptoms and aging. It also supports the immune system’s ability to combat viruses and bacteria. Found in a variety of fruits and vegetables, including bell peppers, strawberries, and broccoli, vitamin C is essential for maintaining health.

Some studies involving marathon runners and skiers under physical stress suggest that vitamin C can stop and shorten the duration of colds. These findings have led to assertions that vitamin C might lower the risk of catching a cold altogether.

Nevertheless, most evidence indicates that preventive vitamin C does not significantly decrease the likelihood of colds in the general population. Taking large doses of vitamin C at the onset of cold symptoms may not necessarily shorten the duration of illness. Moreover, excessive vitamin C intake can lead to side effects such as nausea and diarrhea, so it is advisable to avoid supplements exceeding 2,000 mg daily.

Using Vitamin C When You Have a Cold

When cold symptoms arise, many people reach for vitamin C supplements or orange juice in hopes of reducing their duration. However, the effectiveness of this nutrient in preventing colds appears to be limited.

A century after Linus Pauling’s influential book on vitamin C and colds, controlled trials reveal that regular vitamin C intake does not significantly affect the average person’s risk of contracting a cold, based on 29 trial comparisons.

Conversely, a small number of studies indicate that beginning vitamin C supplementation at the first sign of a cold can reduce symptom duration by approximately one day. These findings suggest a dose-response relationship, leading some researchers to propose that higher doses may be necessary to prevent colds effectively.

Is Vitamin C Beneficial for Colds?

Vitamin C is a water-soluble nutrient essential for most organisms. Isolated in the 1930s, it gained popularity when Linus Pauling claimed that a daily dose of one gram could prevent colds. He based this assertion on observations that sailors consuming citrus fruits during long voyages rarely contracted scurvy, while those who did frequently suffered from respiratory infections.

This nutrient is a crucial component of immune system cells and helps neutralize free radicals—unstable atoms that can lead to illness and aging. Additionally, it plays a role in collagen production, blood vessel formation, and cartilage maintenance. Vitamin C is also involved in producing specific neurotransmitters and aids in metabolizing fatty acids for energy.

Several studies indicate that regular vitamin C supplementation can reduce the duration of colds by about 8% in adults and 14% in children, while also alleviating the severity of cold symptoms.

Vitamin C is widely recognized as a potent ally for the immune system. Found abundantly in various fruits and vegetables, it is also a common ingredient in many fortified cereals.

At the first hint of a cold, many individuals instinctively reach for vitamin C supplements like Emergen-C or a refreshing glass of orange juice. But does consuming high doses of vitamin C truly make a difference?

The Role of Vitamin C in Immunity

Vitamin C plays a significant role in addressing numerous health issues, including infections, wound healing, and inflammatory disorders. This vital nutrient is present in a variety of foods, particularly fruits and vegetables, and can also be taken as a dietary supplement.

The immune-boosting properties of vitamin C are well-documented, making it a staple in countless diets. However, can it actually prevent colds and flu?

Research indicates that while high doses of vitamin C do not prevent colds, regular intake over time can potentially reduce the duration of illness by approximately 10%. For instance, a cold that typically lasts ten days could be shortened to nine days if vitamin C is taken consistently.

Nonetheless, rushing to purchase a vitamin C supplement at the first sign of a sniffle may not be the best approach. Instead, prioritize a balanced diet, adequate sleep, stress management, and proper hydration. These lifestyle choices significantly enhance your immune system more effectively than vitamin C megadosing.

Understanding Vitamin D’s Impact

Vitamin D serves as a powerful immune booster and plays a crucial role in calcium absorption, heart health, and bone strength. Research suggests that it may also help in preventing colds and flu.

A recent study published on the bioRxiv preprint server revealed that high doses of vitamin D can shorten the duration of flu infections and alleviate symptoms such as chest pain and fever. The findings support the idea that vitamin D supplementation could complement influenza vaccinations, particularly during the colder months.

A randomized controlled trial led by QIMR Berghofer demonstrated that a daily vitamin D capsule reduced the incidence of acute respiratory infections by half in participants with low baseline levels (below 25 nanomoles per liter). Even those with higher baseline levels experienced a 10% reduction in infections, albeit with a less pronounced effect. Participants in the study recorded their symptoms in a database and maintained health diaries throughout the trial.

The Benefits of Polyphenols

Polyphenols may sound complex, but they are beneficial plant compounds that exist in over 8,000 known varieties. These compounds are categorized based on their chemical structures, including flavonoids (like quercetin and kaempferol), phenolic acids (such as tannins found in red wine), lignans (present in flax seeds and whole grains), and stilbenes (like resveratrol).

As antioxidants, polyphenols help neutralize free radicals—unstable molecules that can cause cellular damage and contribute to chronic diseases. They also exhibit anti-inflammatory properties, which may help reduce the risk of conditions such as heart disease, arthritis, and diabetes.

A well-rounded diet rich in fruits, vegetables, herbs, spices, nuts, and whole grains should provide a healthy intake of polyphenols. Aim for approximately 1,000 milligrams of polyphenols daily. If you’re considering a supplement, consult your healthcare provider first to ensure you choose a high-quality product from a reputable brand.

Vitamin B6: A Supportive Nutrient

Vitamin B6, found in various fruits, vegetables, and legumes, plays a vital role in producing red blood cells, supporting a healthy nervous system, and enhancing immune function. It also acts as a natural antihistamine.

While vitamin B6 alone may not prevent colds or flu, it can help alleviate symptoms and shorten the duration of illness. You can obtain sufficient vitamin B6 through whole foods or supplements.

Vitamin C is highly concentrated in immune cells and tends to deplete quickly during infections. Therefore, taking a high dose of vitamin C can significantly reduce the duration of illness. However, be cautious not to exceed 2,000 mg per day, as higher doses can lead to dizziness, nausea, and kidney stones.
