Critical Reviews in Food Science and Nutrition
|April 2, 2025
Summary
Sustainable food systems research shows a trend towards new technologies like machine learning and CRISPR, but underfunds critical micronutrient deficiencies. More focus is needed on iron, zinc, and vitamin A for global nutrition goals.
Area of Science:
- Nutrition Science
- Food Science
- Bibliometrics
Background:
- Sustainable food systems are crucial for combating micronutrient malnutrition and achieving Sustainable Development Goals (SDGs).
- Micronutrient research trends and thematic clusters require analysis within the SDGs framework.
Purpose of the Study:
- To conduct a bibliometric analysis of micronutrient research from 2015 to 2023.
- To identify key trends, thematic clusters, and research priorities within the SDGs framework.
- To evaluate the alignment of research priorities with global nutrition challenges and SDGs.
Main Methods:
- Bibliometric analysis of publications from the Web of Science (2015-2023).
- Science mapping techniques to identify trends and thematic clusters.
- Analysis of research focus in relation to micronutrient deficiencies and SDGs.
Main Results:
- Key trends include machine learning, macroalgae, CRISPR/Cas9 for biofortification, and heavy metal contamination.
- Research clusters emphasize bone health (osteoporosis, vitamin D), aligning with SDG 3.
- Underrepresentation of research on iron, zinc, and vitamin A deficiencies despite high global impact, particularly in low- and middle-income countries.
Conclusions:
- Current research priorities may not sufficiently address critical micronutrient gaps and SDGs 2 and 12.
- A balance is needed between technological advancements and addressing underfunded micronutrient deficiencies.
- Targeted research is essential to improve global nutrition and achieve sustainable food system goals.

18.6K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

01:10Nature and Nurture
20.3K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

02:11The Roles of Bacteria and Fungi in Plant Nutrition
34.8K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.

01:40Overview of Metabolism
29.2K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

6.0K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
