1. Beet (Beta vulgaris) and Cancers
Cancer is a class of diseases in which a group of cells growing and multiplying disordered and uncontrollable way in our body, have become progressively worse and damaged other healthy tissues, sometimes spreads to other organs in the body via lymph or blood and results may be in death.
Food intake can help to prevent and treat cancers. 

The Benefits
Red beetroot (Beta vulgaris L.) extract (B), approved to be used as coloring by the FDA, and anticancer drug doxorubicin (D), when are tested for cytotoxic effects against the three cancer cells, showed both exerted the positive effects but the synergistic cytotoxicity was best when the B:D ratio of 1:5 was used in pancreatic (PaCa) cells at IC50, IC75 and IC90 dose levels and in breast (MCF-7) cells at IC90 dose level. Other in the study in the same comparison of the anti cancers effect of doxorubicin and the beetroot extract, both are found to exhibit a dose-dependent cytotoxic effect in the two cancer cell lines tested. Although the cytotoxicity of the beetroot extract was significantly lower when compared to doxorubicin in human prostate (PC-3), and breast (MCF-7) and cancer cell lines.

2. Beet (Beta vulgaris) and Hypertension
Beet is best known as the beetroot or garden beet and belong to the amaranth family. It is a perennial plant with leafy stems growing to 1–2 m tall.
Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. High blood pressure means raising pressure in your heart.If it stays high over time it can damage the body in many ways.

The Benefits
Consumption of beetroot juice on a low nitrate diet is said to lower blood pressure (BP) and therefore reduce the risk of cardiovascular events. In a fifteen women and fifteen men participated in a double-blind, randomized, placebo-controlled, crossover study, showed a positive effect of beetroot juice in addition to a normal diet in men. Other study also found a low dose of 100g exerts the significant hypotensive effects which was unaffected by processing or the presence of betacyanins. Also enriching bread with beetroot may be a suitable vehicle to increase intakes of cardioprotective beetroot in the diet and may provide new therapeutic perspectives in the management of hypertension.

Side effects
1.
Oxalates Oxalates in the beet can cause kidney and gallbadder problem. People with above diseases should contact their doctor before consuming.
2. Increase the rick of lowering calcium absorption for people with weak digestive system.
3. Etc.

Beside the major chemical constituents betalains and phenolics, it also contains lesser amount of isobetanin, probetanin, neobetanin, indicaxanthin, vulgaxanthins, etc.

The Benefits
Endothelial dysfunctionis associated with patients with insulin resistance or type 2 diabetes. evidences insome studies suggested that postprandial endothelial function was improve in patients with insulin resistance or type 2 diabetes, after a single dose of a Exenatide, glucagon-like peptide-1 agonist (GLP-1 agonist) medication just before the meal. In the study to test the effects of  endothelial function after the intake of beetroot juice in overweight and slightly obese men following a mixed meal,, the postprandial impairment in Flow-mediated dilation (FMD) was improved, plasma concentrations of the circulating NO pool were higher at T60, T120, and T240. Of these results, researchers suggested that a single dose of beet juice attenuates the postprandial impairment of FMD following a mixed meal and may be a potential alternative option to treat early onset of patient with type II diabetes, with little or no side effects.

Side effects
1.
Oxalates Oxalates in the beet can cause kidney and gallbadder problem. People with above diseases should contact their doctor before consuming.
2. Increase the rick of lowering calcium absorption for people with weak digestive system.
3. Etc.

4. Beet (Beta vulgaris) as antioxidants
Beet is best known as the beetroot or garden beet and belong to the amaranth family. It is a perennial plant with leafy stems growing to 1–2 m tall.
Most of heart diseases are caused by high blood pressure contributes to hardening of the arteries. High levels of bad cholesterol (LDL) build up in the arteries as a result of uncontrolled diet with high levels of saturated fat and trans fat. All these add to the formation of atherosclerosis lesions and eventually arterial blockage or anything that serves to damage the inner lining of blood vessels and impedes the transportation of oxygen and nutrition to the heart can be defined as a risk of heart disease.

Beside the major chemical constituents betalains and phenolics, it also contains lesser amount of isobetanin, probetanin, neobetanin, indicaxanthin, vulgaxanthins, etc.

The Benefits
Betanin a main chemical constituent found in  beet juice has exerted its hepatoprotective and anticarcinogenic effects, through the activation of Nrf2 and subsequent induction of the expression of genes controlled by this factor(Activation of Nrf2 essentially opens the door for the production of numbers of our body’s most important antioxidants as excessive free radicals induce better antioxidant production) in non-tumour THLE-2 cell line. In simple words, betanin in beet root enhances the antioxidant effects in protection of the liver against the development of liver cancers and diseases.

Side effects
1.
Oxalates Oxalates in the beet can cause kidney and gallbadder problem. People with above diseases should contact their doctor before consuming.
2. Increase the rick of lowering calcium absorption for people with weak digestive system.
3. Etc.

The benefits
Vegetables rich in inorganic nitrate has found to be beneficial vascular effects, including reducing blood pressure, inhibiting platelet aggregation, preserving or improving endothelial dysfunction, etc. In the study of health volunteers, approximately 3 hours after ingestion of a dietary nitrate load (beetroot juice 500 mL), it enhanced the rise in plasma nitrite, decrease in blood pressure, and inhibited on platelet aggregation. Beet juice is no doubt exerted its vasoprotective effects through activity of nitrite converted from the ingested nitrate and  the beneficial effects of a vegetable-rich diet may be considered as a low cost treatment of cardiovascular disease.

Side effects
1.
Oxalates Oxalates in the beet can cause kidney and gallbadder problem. People with above diseases should contact their doctor before consuming.
2. Increase the rick of lowering calcium absorption for people with weak digestive system.
