Brief Summary
The goal of this clinical trial is to learn if eating grapes can improve muscle strength and thinking in generally healthy women over 65. The main questions it aims to answer are: Does eating grapes improve muscle strength in women over 65? Does eating grapes improve cognition in women over 65? Participants will be asked to take part in 4 sessions on campus. Each session will include: Functional muscle strength testing Cognitive testing Blood draws

Study Arms (1)
Grape Powder Arm
EXPERIMENTALAll subjects will consume two 36g packets of grape powder (mixed with water) daily for two, 2-week periods during the study.
Interventions
All participants will consume two 36g packets of grape powder (mixed with water) daily for two, 2-week periods during the study. Participants will mix pre-measured grape powder with water and drink twice a day (once in the morning and in the afternoon/evening) for two weeks.
Eligibility Criteria
You may qualify if:
- Healthy female (confirmed by medical history)
- Aged 65 or older;
- Able to walk household distances without assistance from another person
- Non-smoker;
- Dominant hand grip strength at or below normal value for age and gender;
- Had not consumed recreational drugs for one week prior;
- Agreed not to participate in any clinical or patch test studies at Day 1 through study completion;
- Completed a medical intake;
- Read, understood, and signed an informed consent.
You may not qualify if:
- Using nasally inhaled/systemic/topical corticosteroids within 4 weeks prior to and/or during the study, or systemic/topical antihistamines 72 hours prior to and during the study;
- Using certain antifungal drugs, antihistamines (including diphenhydramine, or Benadryl), antibiotics 4 (including "sulfa" drugs, quinolones and tetracyclines), oral diabetes drugs, sulfonylureas, diuretics, and tricyclic antidepressants. Some herbal supplements such as St. John's Wort would make a person ineligible;
- Not willing to refrain from using acetaminophen (occasional use permitted, except within 48 hours of a study visit) or systemic/topical anti-inflammatory analgesics such as aspirin, Aleve, Motrin, Advil, Orudis, or Nuprin for 72 hours prior to and during study visits;
- Any of the following in the 4 weeks prior to start of study:
- Major surgery for any indication
- On cytotoxic chemotherapy for any indication (including methotrexate for arthritis)
- Hormonal therapy for cancer prevention (including tamoxifen). Note: treatment with finasteride/dutasteride for BPH does not render a participant ineligible
- Using medication which, in the opinion of the Investigator, would interfere with the study results (e.g., anti-inflammatory medications, antipsychotics, anticonvulsants with potential pain relief effects, immunomodulatory medications; blood thinners);
- Known sensitivity or allergy to grape powder;
- Nut allergies;
- Had received treatment for any type of internal cancer within 5 years prior to study entry;
- Had a history of or currently being treated for:
- Hepatitis;
- Diabetes (including insulin injections);
- Solid organ or bone marrow transplant
- +14 more criteria
