Title: The SU.VI.MAX Study. A Randomized, Placebo-controlled Prevention Trial of the Health Effects of Antioxidant Vitamins and Minerals.
Brief Summary: It has been suggested that a low dietary intake of antioxidant vitamins and minerals increases the incidence rate of cardiovascular disease and cancer. To date, however, the published results of randomized, placebo-controlled trials of supplements containing antioxidant nutrients have not provided clear evidence of a beneficial effect. We tested the efficacy of nutritional doses of supplementation with a combination of antioxidant vitamins and minerals in reducing the incidence of cancer and ischemic cardiovascular disease in the general population.


Options:
A: Inclusion Criteria:

* The study will enroll subjects, both men and women with type 2 diabetes of at least six months duration. The age of enrolled subjects will range from 21-60 years old. An HbA1c blood test must show that the person's diabetes is under control. Eligible subjects must have normal electrocardiogram tracings and normal hematological, electrolyte and liver laboratory results at screening. Females of childbearing age must agree to use an effective form of birth control throughout the study period.

Exclusion Criteria:

* Subjects will be excluded if they have known vascular disease, uncontrolled hypertension (\>140/90 mmHg), marked hyperlipidemia (serum low density lipoprotein \> 4.1 mmol/L or serum triglycerides \> 7.8 mmol/L), and a body mass index greater than 40 kg/m2 (range 27-40). Other important exclusion criteria are cigarette smoking, volunteers taking Coumadin, and recent use of antioxidant supplements or aspirin. Females who are pregnant or breastfeeding will be excluded. People cannot participate in this study if they are taking medications (other than antidiabetic medications) which may affect blood sugar.
B: Inclusion Criteria:

* CT or MRI since disease onset excluding structural lesions sufficient to account for the participant's dementia
* Mini-Mental State Exam (MMSE) score between 12 and 26, inclusively
* Clinical Dementia Rating (CDR) score of 1 or 2 (mild to moderate AD severity) at both screening and baseline
* Women must be 2-years post-menopausal or surgically sterile.
* Generally healthy and ambulatory or ambulatory-aided (i.e., walker or cane); vision and hearing (hearing aid permissible) sufficient for compliance with testing procedures
* Concomitant medications: Participants may be on stable doses of cholinesterase inhibitors for 90 days prior to screening (may not be started during the trial); antidepressant or antipsychotic medications are acceptable if symptoms are controlled and therapy is at stable dosage for at least 30 days prior to screening; vitamin E at 200 IU daily will be provided to all participants beginning at baseline/randomization (higher doses must be discontinued at the screening visit)

Exclusion Criteria:

* Absence of a reliable caregiver who is willing to participate and comply with protocol responsibilities
* Diabetes mellitus requiring medical therapy (diet-controlled diabetes is acceptable)
* Acute or chronic liver failure, hepatitis within the last two years, or history of drug-induced liver transaminase elevations
* Heart failure meeting New York Heart Association Grade III or IV criteria (i.e., functionally disabling)
* Evidence of active gastrointestinal, renal, pulmonary, endocrine or cardiovascular system disease sufficient to cause cognitive impairment or interfere with past levels of daily function; participants with controlled hypertension (supine diastolic BP \< 95mmHg), right bundle branch block (complete or partial) and pacemakers may be included in the study; participants with thyroid disease also may be included in the study, provided they are euthyroid on treatment
* Active treatment for cancer or history of cancer within 3 years of screening (basal cell and squamous cells skin cancers are acceptable; incidental finding of carcinoma cells at transurethral prostate resection without subsequent medical or surgical therapy is acceptable)
* Evidence of other psychiatric/neurologic disorders sufficient to be the primary source of cognitive impairment (i.e., stroke, idiopathic Parkinson's disease, schizophrenia, bipolar or unipolar depression, seizure disorder, head injury with loss of consciousness within the past year) or a modified Hachinski's ischemia score of 5 or greater; delusions, hallucinations or depression not successfully treated or not on stable medical therapy for these conditions 30 days prior to enrollment; known or suspected history (within the past 10 years) of alcoholism or drug misuse
* Participants and/or caregivers who are unwilling or unable to fulfill the requirements of the study
* Any condition which would make the participant or the caregiver, in the opinion of the investigator, unsuitable for the study
C: DISEASE CHARACTERISTICS:

* Healthy male volunteers
* Digital rectal examination (DRE) deemed not suspicious for prostate cancer performed within 364 days prior to study entry

  * Participants with a suspicious DRE are ineligible even if a recent or subsequent biopsy is negative for cancer
* Total prostate-specific antigen ≤ 4.0 ng/mL within 364 days prior to study entry
* No prior prostate cancer or high-grade (grade 2-3) prostatic intraepithelial neoplasia
