Is there an effect of dietary intake on MS-related fatigue? - A systematic literature review

Abstract

Insights

Dietary interventions may help manage fatigue in multiple sclerosis (MS). Adequate magnesium and folate intake showed potential benefits, but more research is needed to confirm these findings for persons with MS.

Area of Science:

  • Neurology
  • Nutrition Science
  • Systematic Review Methodology

Background:

  • Fatigue is the most prevalent symptom in multiple sclerosis (MS), affecting up to 90% of patients.
  • Current pharmacological treatments for MS-related fatigue offer limited efficacy.
  • Growing interest exists in dietary interventions for managing MS symptoms.

Purpose of the Study:

  • To systematically review the impact of holistic dietary intake on fatigue perception in adults with MS.
  • To synthesize evidence from intervention trials on dietary patterns and MS fatigue.

Main Methods:

  • Comprehensive literature search across seven major databases (Embase, Medline, Web of Science, etc.).
  • Inclusion of intervention trials focusing on holistic dietary regimens and subjective fatigue in adult MS patients.
  • Risk of bias assessment using a modified Downs and Black checklist.

Main Results:

  • Four studies (one pilot trial, three RCTs) met inclusion criteria.
  • Dietary interventions included low-fat, low-fat/starchy plant food, and modified paleo diets (3-12 months).
  • Two studies reported significant fatigue improvements with adequate folate and magnesium intake.

Conclusions:

  • Holistic dietary intake shows potential for reducing MS-related fatigue.
  • Evidence suggests a trend towards decreased fatigue with adequate magnesium and folate.
  • Further robust research is required to establish definitive conclusions.

Fatigue

Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Dietary Connections

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

Regulation of Water Intake01:25

Regulation of Water Intake

Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...

Regulation of Food Intake01:30

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
