Role of Nutraceuticals in Disease Management

Based on numerous research studies, nutraceuticals play an important role in the determination, prevention, and treatment of diseases like diabetes, cardiovascular disease, cancer, and irritable bowel syndrome.

Management of Diabetes

Diabetes is a metabolic disease characterized by high blood sugar levels (hyperglycemia) for a prolonged period. If untreated, it can damage nerves, eyes, kidneys, and other organs. It is caused by a lack of insulin (Type I) or the cells’ inability to uptake glucose (Type II).

Effective Nutraceuticals for Diabetes:

  • Isoflavones: Improve the function of pancreatic B-cells and stimulate glucose uptake. Effective in Type II Diabetes Mellitus (e.g., Apigenin found in oranges and onions protects B-cells from damage).
  • Omega-3 Fatty Acids: Reduce glucose intolerance in patients. Insulin is required for synthesizing long-chain n-3 fatty acids (e.g., Alpha-Linolenic Acid found in berries).
  • Dietary Fibers: Aid in blood sugar regulation.

Cancer Prevention

Cancer is a disease in which abnormal cells divide uncontrollably and destroy body tissue. It is a major public health problem, with almost 15 million new cases reported in 2020. There are more than 100 types of cancer.

Role of Specific Nutraceuticals:

  • Flavonoids: Found in citrus fruits; they act as antioxidants and have chemopreventive properties.
  • Lycopene: Found in fruits (guava, papaya) and vegetables (tomato, potato). It prevents cancer by decreasing oxidative damage to DNA.
  • Phytoestrogens: Found in plums, pears, onions, and tea; these are active in the prevention of breast cancer.
