Participants will receive 12 weeks of weekly food deliveries from Dig Deep Farms.

Each delivery will include a selection of seasonal fresh vegetables and a rotation of either a whole grain or a whole-grain food (3+ grams of fiber/serving). Whole grains will include brown rice, oatmeal, barley, quinoa; whole grain foods will include cereal, pasta, tortillas, bread, crackers. Delivery sizes will be scaled to the three corresponding household sizes: 2-3 people; 4-5 people; or 6 or more people.

Food will be delivered by Dig Deep Farms, which already has an established food subscription delivery system.

(Control group participants will receive the same delivery schedule, but delayed to begin 6 months after their study enrollment.)

Weight (kg) and height (cm) will be measured and Body Mass Index (BMI) will be calculated in kg/m^2. Height and weight will be gathered using standardized protocols with a portable scale and stadiometer. At baseline, these will be measured in triplicate for accuracy.

Waist-height ratio (cm) will be calculated and compared over time. Waist circumference (cm) will be measured at iliac crest. Height (cm) will be measured using standardized protocols.

Participants will answer 10 questions about their stress related to the pandemic. Scale is made up of 10 items, each of which offers five response options: never, almost never, occasionally, almost always and always. Items 1, 2, 3, 6, 9 and 10 are scored directly from 0 to 4 and items 4, 5, 7 and 8, conversely, from 4 to 0.

Scores range from 0 to 40, higher scores indicating greater stress.

The PSS-10-C was adapted from the Scale of Perceived Stress (PSS-10) and independently validated during March 2020 in response to government-mandated COVID-19 quarantines in Columbia (see Campo-Arias et al 2020 in the references section)

Diabetes-related stress will be measured using the validated 20-item Problem Areas in Diabetes Survey (PAID) questionnaire. Each item is scored from 0 (not a problem) to 4 (serious problem). The sum of all item scores multiplied by 1.25 gives the total PAID score.

Scores range from 0 to 100, higher scores reflecting greater emotional distress.

Index participants and adult household members will receive the Short Form-8 (SF-8) questionnaire. SF-8 is an 8-item instrument that measures general aspects of health-related quality of life. Each item covers a different domain: overall health, physical functioning, role physical (difficulties with daily work because of physical pain), bodily pain, vitality, social functioning, mental health, and role emotional (absence from daily activities because of emotional problems).

Items are assessed individual 5- or 6-point Likert scales, a higher score on each question indicates poorer quality of life in that domain.

Instead of the SF-8 (see previous outcome), adolescent household members will receive the Kid-Screen-10, a questionnaire is designed for children ages 8-18 to assess subjective health and psychological, mental, and social well-being.

Scores range from 10 to 50, with higher scores indicating higher health-related quality of life.

Possible depression will be measured using the Patient Health Questionnaire (PHQ-8), which measures 8 criteria from the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders). Each criteria is scored from "0" (not at all) to "3" (nearly every day). Range is 0-24, higher total score indicates more severe depression.

For index participants, depression will be measured using the Patient Health Questionnaire (PHQ-9), which measures 8 criteria from the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders) and a ninth question on suicidal thoughts. Each criteria is scored from "0" (not at all) to "3" (nearly every day). Range is 0-27, higher total score indicates more severe depression.

Level of anxiety will be measured using the General Anxiety Disorder-7 (GAD-7). This is a 7 item instrument that uses some of the DSM-V (Diagnostic and Statistical Manual of Mental Disorders) criteria for General Anxiety Disorder along with measuring anxiety symptom severity. Scores range from 0 to 21, higher scores indicate more severe anxiety.

The validated UCLA 3 item Loneliness Scale will be used. The scale is designed to measure one's subjective feelings of loneliness as well as feelings of social isolation. Participants rate each item as "hardly ever" (1), "some of the time" (2), or "often" (3).

Scores range from 3 to 9, higher scores indicate greater levels of loneliness.

Index participants will complete three 24-hour diet recalls using the Automated Self-Administered 24-hour (ASA24®) Dietary Assessment Tool. The module includes multiple-pass methodology to capture all foods eaten in the previous 24 hours. A researcher will administer the tool to reduce respondent burden. Output for 24-hour diet recall is extensive, but will include our key dietary outcomes for daily (averaged) intakes of: total vegetables, dark green vegetables, beans/legumes, and whole grains.

Scores:

Healthy Eating Index (HEI): 0 to 100, higher indicates greater alignment with healthy dietary guidelines Fruit & vegetable: 0-20 servings/day, higher scores preferred Total calorie intake: 1000-6000 kcal/day Total fat: 0-400 g/day

Interview method adapted from Conway et al 2004 (see references section).

Household members will be given the 10-item Dietary Screener Questionnaire (DSQ-10). The questionnaire will capture consumption of fruit/vegetables, fiber, whole grains, and added sugars. Scores range from 0 to 100, higher scores indicate more frequent consumption of healthy foods.

They will also be asked additional questions about whole grain foods, which will be scored the same way. These will be based on the dietary screener developed by Thompson and colleagues (see Thompson et al 2017 in references section).

We will create a multi-part questionnaire to assess diet-related behaviors:

1. Self-efficacy to eat fruits/vegetables will be measured using selected items from the National Cancer Institute's Food Attitudes and Behaviors Survey. Scores range from 7 to 35, higher score indicates greater self-efficacy/confidence in ability to consume fresh fruits and veg.
2. To assess food preferences, participants will be asked Likert-style questions about specific vegetables and whole grains. Higher score indicates stronger "liking".
3. To assess healthy food consumption, participants will be asked a series of questions about whether they ate specific whole grain foods in the past 7 days. Higher score indicates more frequent consumption.
4. There will also be three questions specifically about participants use of brown rice (regular and instant). Individual answers will be compared across time points.

Participants will be asked a series of questions designed by the research team to examine changes in their whole grain and vegetable consumption over the past 6 months. Higher score is generally a better outcome as it indicates increase in consumption of these healthy foods.

Using the 7-day Physical Activity Recall, each participant will complete a semi-structured interview that estimates their time spent doing physical and sleep activities in the past 7 days.

Scores are:

• Leisure time moderate and vigorous physical activity, ranging from 0-1500 min/week, higher scores preferred
• Total energy expenditure, ranging from 06-60 kcal per kg per day, lower scores preferred.

Comprises 10 items to which responses are given on a seven-point Likert scale ranging from "strongly disagree" to "strongly agree."

Score ranges from 10 to 70, a higher total score indicates greater food neophobia level and lower tendency to try unfamiliar foods.

Participants will be asked a three part-questionnaire about control and food choices in the past 6 months:

1. Nutrition security is measured with 4 items about food choice availability. Answers are never, rarely, sometimes, often, or always; higher rankings indicates greater nutrition insecurity. Scores range 0-16.
2. Healthfulness Control is measured with 2 items about sense of control over what they ate or served to their families. Answers are never, rarely, sometimes, often, or always; higher rankings indicates greater control. Scores range 0-8.
3. Utilization barriers are measured with 2 items about whether participants are able to select healthy foods and make healthy meals. Each item is ranked never true, sometimes true, often true; higher ranking indicates greater utilization barrier. Scores range 0-8.

The Nutrition Security Screener (NSS) was developed by Tufts University, Kaiser Permanente, and Los Angeles Department of Public Health. The questionnaire contains 14 questions, divided into two sections:

1. "How hard was it for you or your household to regularly get and eat healthy foods?" Answers are "very hard" (0) , "hard" (1), "somewhat hard"(2) "not very hard" (3) and "not hard at all." (4).
2. Participants are asked rate 13 different barriers to being able to eat or prepare healthy meals. Each item is ranked "very little or not at all", "somewhat" or "a great deal."

Question 1 will be scored on a scale of 1-4 to indicate if food security is very low, low, marginal, or secure. Measure designers have not validated a scale for question 2, so it will be analyzed descriptively.

Community Supported Agriculture (CSA) is a local farm-to-table model where customers can sign up for a subscription with a local farm and receive a weekly box of seasonal fruits and vegetables.

Participants will be asked a 4 item questionnaire to gauge their experiences with, and interest in, such food boxes, including how much they would be willing to spend for one (e.g. $10-20 per bag). There is no scoring rubric, results are descriptive.

Each participant will complete the USDA's U.S. Household Food Security Survey Module: Six-Item Short Form to measure household food security.

Raw scores are converted into food security status as follows: 0-1 indicates high or marginal food security, 2-4 indicates low food security, and 5-6 indicates very low food security.

Participants are asked whether their household currently receives (or has received in the past 6 months) various sorts of food assistance, such as:

• Women, Infants and Children Program (WIC)
• government food assistance programs known as CalFresh, SNAP (Supplemental Nutrition Assistance Program), EBT (Electronic Benefits Transfer), or food stamps
• other sources of free food within the last 6 months such as church, food pantry / food bank, soup kitchen, etc, including an open-ended question

There is no scoring rubric, results are descriptive.
