Abstract

Chia (Salvia hispanica L.) is a small seed that comes from an annual herbaceous plant, Salvia hispanica L. In recent years, usage of Chia seeds has tremendously grown due to their high nutritional and medicinal values. Chia was cultivated by Mesopotamian cultures, but then disappeared for centuries until the middle of the 20th century, when it was rediscovered. Chia seeds contain healthy ω-3 fatty acids, polyunsaturated fatty acids, dietary fiber, proteins, vitamins, and some minerals. Besides this, the seeds are an excellent source of polyphenols and antioxidants, such as caffeic acid, rosmarinic acid, myricetin, quercetin, and others. Today, chia has been analyzed in different areas of research. Researches around the world have been investigating the benefits of chia seeds in the medicinal, pharmaceutical, and food industry. Chia oil is today one of the most valuable oils on the market. Different extraction methods have been used to produce the oil. In the present study, an extensive overview of the chemical composition, nutritional properties, and antioxidant and antimicrobial activities, along with extraction methods used to produce chia oil, will be discussed.

  • Chia seeds contain omega-3 fatty acids, magnesium, potassium, calcium, and flavonoids (quercetin, chlorogenic acid, caffeic acid) that have been linked to reduced blood pressure.

    “They are rich in crucial fatty acids, particularly with a high omega-3 to omega-6 ratio, linked to reduced BP and a lower risk of CVD [43–45]. A 100-g serving of chia provides significant amounts of magnesium, potassium, and calcium, all potent vasodilators and vascular smooth muscle contraction inhibitors, effectively reducing BP [46–49]. Additionally, chia seeds contain flavonoids such as querc”

    From Effects of chia seed (Salvia hispanica L.) supplementation on cardiometabolic health in overweight subjects: a systematic review and meta-analysis of RCTs (2024) · cites this paper as [14]

    Section 2.3 (Minerals; page unavailable) confirms that chia seeds contain magnesium, potassium, and calcium, but does not link those minerals to lower blood pressure. Sections 2.4 (Phenolic Compounds) and 6 (Therapeutic Value; pages unavailable) link the named flavonoids and omega-3 fatty acids to antihypertensive effects, and Section 6 reports reduced diastolic blood pressure after chia consumption. The specific blood-pressure effect attributed to the minerals is not supported by these passages. (LLM, conf=0.87)

  • Chia seeds may improve lipid profile, glycemic markers, antioxidant properties, blood pressure regulation, and weight management.

    “According to recent research, chia seeds may improve lipid profile, glycemic markers, antioxidant properties, blood pressure (BP) regulation, and weight management [14, 15].”
  • The primary phenolics content in chia seeds (μg per 100 g) includes caffeic acid (27.0), quercetin (0.17), kaempferol (0.01), daidzin (6.6), glycitin (1.4), and genistin (3.4).

    “The primary phenolics content in chia seeds (in µg per 100 g), includes caffeic acid (27.0), quercetin (0.17), kaempferol (0.01), daidzin (6.6), glycitin (1.4), and genistin (3.4) [27].”
  • Flavonoids in chia seeds such as caffeic acid, chlorogenic acid, and quercetin provide anti-carcinogenic and anti-hypertensive properties.

    “Flavonoids in chia seeds, such as caffeic acid, chlorogenic acid, and quercetin, provide anti-carcinogenic and anti-hypertensive properties [27].”
  • Chia seed peptides (16 kDa) show an antihypertensive influence on angiotensin I-converting enzyme (ACE).

    “Also, these peptides (16 kDa) show an antihypertensive influence on angiotensin I-converting enzyme (ACE) [27,95].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
