High salt intake is positively linked to many health problems, but the effect of mineral-rich sea salt (SS) has rarely been studied. To better understand the physiological effects of SS intake, the changes in general characteristics, metabolites, steroid hormones, and gut microbiota of SS-fed rats were investigated. Male rats were fed either a norm...

Metabolic diseases (MDs), including cardiovascular diseases (CVDs) and diabetes, occur when the body’s normal metabolic processes are disrupted. Behavioral risk factors such as obesity, physical inactivity, and dietary habits are strongly associated with a higher risk of MD. However, scientific evidence strongly suggests that balanced, healthy diet...

Endothelial dysfunction is directly involved in consequence of various metabolic syndromes such as diabetes and hypertension. In this study, we investigated the preventive effects of two ark clams [ark shell (AS, Scapharca subcre-nata) and granular ark (GA, Tegillarca granosa)] on endothelial dysfunction induced by a high-fat diet. Wistar rats were...

We investigated the antihypertensive effects of Artemisia scoparia (AS) in spontaneously hypertensive rats (SHR). The rats were fed diets containing 2% (w/w) hot water extracts of AS aerial parts for 6 weeks. The AS group had significantly lower systolic and diastolic blood pressure levels than the control group. The AS group also had lower angiote...

We have investigated the in vitro and in vivo antioxidative activity of solar sea salts(SS) roasted with (BS) or without (RS) bamboo, which are widely consumed as dietary salts in Korea. BS exhibited antioxidative activity in the in vitro assays of various radical-scavenging activities and DNA oxidation. RS also scavenged superoxide radicals and in...

Certain solar sea salts have a high content of essential minerals other than NaCl. The effects of minerals in sea salts on oxidative stress in rats were investigated. Mineral-rich salt (MRS) and mineral-deficient salt (MDS) did not scavenge DPPH radicals. When MRS and MDS (equivalent to 1.8 g NaCl/kg/day) and a saline control were orally administer...

... It has been well-established that oxidative stress caused by an overabundance of reactive oxygen species (ROS) that remains in the organism is the root of the pathogenesis of a number of disorders [1]. Oxidative stress can be triggered by various external and internal factors, including elevated blood glucose and insulin levels, which in turn lead to an increased risk of chronic non-communicable diseases, including obesity and type 2 diabetes [2,3]. Type 2 diabetes is now a serious problem in many countries around the world and represents 90% of all types of this disease, while being one of the five leading causes of death in the human population [4]. ...
... The effects of Scapharca subcrenata (AS) and Tegillarca granosa (GA) on high-fat diet-induced endothelial dysfunction were studied. The results showed that AS and GA could increase the expression level of vasodilation-related proteins and inhibit the expression of ET-1 protein to enhance vasoactivity and improve endothelial dysfunction, thereby reducing hypertension (95). Currently, only a few studies have reported the hypertensive effects of shellfish polysaccharides through the regulation of NO (Figure 4); thus, the detailed mechanism is pending further investigation. ...
... These authors attributed the ACE-inhibitory activity to the presence of polyphenols in the extracts. Some ACE-inhibiting polyphenols from other halophytes such as Artemisia scoparia [36] and Salicornia ramosissima [37] have been isolated. Sharifi et al. [38], in an in vivo study with rats, observed an antihypertensive effect of an aqueous extract of the halophyte Tribulus terrestris and suggested that it could be related to an ACE inhibitory effect, as the enzymatic activity was significantly reduced in all tissues. ...
... However, adverse effects, such as high blood pressure [23] due to excessive salt intake, have been reported and thus regular intake of excessive salt should be prevented. Solar sea salt and bamboo salt might play a role in attenuating oxidative stress and inflammation induced by dietary salt containing only NaCl [31,32]. K, Mg, and Ca are the main minerals in solar sea salt and bamboo salt. ...
