What Is Beta Carotene - Health Benefits Of Beta Carotene Explained - Foods High In Beta Carotene

Beta-carotene and cellular health -

The advantage of dietary beta carotene is that the body only converts as much as it needs. Excess vitamin A is toxic. Toxic vitamin A levels can occur if you consume too many supplements. There are a number of ways that beta carotene can benefit human health.

Below, we give some examples:. Beta carotene, like all carotenoids, is an antioxidant. An antioxidant is a substance that inhibits the oxidation of other molecules; it protects the body from free radicals. Free radicals damage cells through oxidation. Eventually, the damage caused by free radicals can cause several chronic illnesses.

Men who have been taking beta carotene supplements for 15 or more years are considerably less likely to experience cognitive decline than other males, researchers from Harvard Medical School reported in Archives of Internal Medicine November issue.

Oxidative stress is thought to be a key factor in cognitive decline, the researchers explained. Studies have shown that antioxidant supplements may help prevent the deterioration of cognition. Their study, involving 4, men, compared those on beta carotene supplements for an average of 18 years to others who were given placebo.

Over the short-term, they found no difference in cognitive decline risk between the two groups of men, but in the long-term it was clear that beta carotene supplements made a significant difference. The researchers emphasized that there may have been other factors which contributed to the slower decline in cognitive abilities among the men in the beta carotene group.

The BMJ published a report in March which showed that high blood beta carotene levels compensate for some of the damage to the lungs caused by oxygen free radicals. They measured the FEV1 of participants and measured their beta carotene blood levels.

FEV1 measures how much air you can breathe out in one go. They found that those with high beta carotene levels had much slower decline in FEV1 measures. If you follow a healthy diet rich in beta carotene you do not need supplements. As mentioned above, supplements can lead to undesirable excesses in beta carotene levels — this cannot occur if your source is from the food you eat.

A French study involving adult females published in the Journal of the National Cancer Institute September issue found that smokers with high beta carotene levels had a higher risk of lung cancer and other smoking-related cancers than other smokers.

They also found that non-smokers with high beta carotene intake had a lower risk of lung cancer. Further research has suggested that the high intake among smokers is nearly always due to supplements, and not food intake. Drug interaction refers to a substance interfering in how a medication works, by either making it less effective, increasing its potency, or changing what it is supposed to do.

Long-term alcohol consumption can interact with beta carotene, raising the chances of developing liver problems. Beta carotene supplements are available for purchase online. Speak to a doctor before taking new supplements.

Usually, the body turns beta carotene into vitamin A, but not always. New studies in mice and humans investigate what this means for health. Arugula is healthful, cruciferous leafy green with a peppery taste.

Such value was substantially lower than the ATRA dosage given to the cells in the previous reports 39 , Therefore, future studies may be needed to achieve physiological relevance by supplementing the cells with an even lower dosage of ATRA. We failed to observe a difference of claudin-1 and occludin protein expressions in LPS-treated cells compared to the cells without LPS treatment.

Multiple publications have portrayed a loss of tight junction proteins in LPS-treated cells 43 — 45 , but none of these studies investigated the effect of LPS on tight junction protein expressions in intestinal epithelial cells.

However, the colonic protein level of claudin-1 was comparable between the control and LPS-treatment groups 46 , which was in line with our finding that LPS did not alter claudin-1 protein expression.

In Caco-2 cells, LPS treatment induced an increase in tight junction permeability by up-regulating TLR4 In the current study, we found that β-carotene significantly decreased TLR4 protein levels, which was associated with an enhancement of claudin-1 and occludin protein concentrations.

One previous study reported that LPS increased cell permeability via an intracellular mechanism involving TLRdependent regulation of CD14 CD14 is a membrane protein that is constitutively expressed on the surfaces of epithelial cells 31 and showed beneficial effects against inflammatory bowel disease by mitigating inflammation and enhancing intestinal barrier function 31 , We found increased CD14 protein expression and reduced TLR4 protein expression in the cells treated with β-carotene, indicating the possibility that β-carotene might enhance claudin-1 and occludin protein levels through regulating CD Nevertheless, we only showed the mechanistic investigation highlighting the correlation between the TLR4-CD14 pathway and tight junction expressions, not causality.

We cannot rule out the possibility that β-carotene alleviated colonic inflammation and improved tight junction proteins through other molecular pathways.

However, it is worth mentioning that in human plasma, LPS concentration ranges from undetectable levels up to 0. Our results showed a reduction of IL-1β and IL-6 in the supernatant with β-carotene treatment at any dosage, and a decrease of TNF-α in the cell WCL with β-carotene treatment at 10, nM, 1, and 10 μM.

However, it remains unknown that whether β-carotene decreased the levels of pro-inflammatory cytokines at transcriptional levels, since we failed to detect the mRNA concentrations of these cytokines by using PCR due to their relatively low quantification in the cells.

Regarding the doses that we selected in this study, previous human studies have shown that plasma β-carotene concentration ranges from ~— nM 54 , β-Carotene concentration can be between and 2, nM in circulation depending on whether it is consumed as a pure compound or within the foods 54 , We recently reported that engineered S.

boulardii synthesized high doses of β-carotene in the colon of mice, and the intake of such engineered probiotics may result in an even higher β-carotene concentration in the gut Altogether, the dosage of β-carotene used in this study is within physiological relevance and can be achieved by humans.

There are several limitations and shortcomings in the current study. First, we could not conduct a TEER assay to explore the LPS-induced changes in cell permeability. A differentiated HT cell line is required to ensure that the cells form a monolayer to conduct TEER assay However, cellular differentiation in HT cells may attenuate their response to LPS by down-regulating TLR4 Furthermore, the differentiated HT cells may express brush-border-associated hydrolases and present brush-border microvilli, which resembles small intestinal cells Since our research focuses on LPS-induced colonic dysfunction, we utilized undifferentiated HT cells, which explains the inability to conduct the TEER assay.

We plan to use NCMD, a normal human colon mucosal epithelial cell line 60 , to investigate further the efficacy of β-carotene in inhibiting LPS-induced colonic inflammation and colonic barrier function.

Since earlier reports showed that the metabolites of carotenoids from eccentric cleavage might present various beneficial effects 62 — 64 , we cannot rule out the possibility that compared with a single β-carotene compound, the eccentric cleavage products from β-carotene may play a more prominent role in anti-inflammation and modulate tight junction proteins.

Finally, we also will conduct experiments to examine whether other major dietary carotenoids would mitigate inflammation in colon. Taken together, we provided the first evidence that β-carotene treatment, even at low dosages, can inhibit LPS-induced colonic inflammation and enhanced the expression of tight junction proteins possibly by down-regulating the TLR4 pathway as summarized in Figure 7.

Further in vitro mechanistic studies and in vivo studies are warranted. Figure 7. Graphical representation of proposed pathway in which β-carotene impacts colonic epithelial cells.

β-Carotene effectively inhibits the LPS-induced inflammatory response within HT colonic epithelial cells by downregulating TLR4, which may block the activation and nuclear translocation of the NF-κB p65 subunit and related downstream signaling. Thus, the release of pro-inflammatory cytokines IL-6, IL-1β, TNF-α is compromised.

The β-carotene induced downregulation of TLR4 may also alleviate the inhibition of its co-receptor CD Enhanced CD14 levels by β-carotene may upregulate tight junction proteins claudin-1 and occludin , leading to decreased intestinal permeability and enhanced barrier integrity.
