Food Security Definition
Food security exists
when all people, at all times,
have physical, social and economic access
to sufficient, safe and nutritious food which
meets their dietary needs and food preferences
for an active and healthy life.

Availability: The “supply side” of food security. Determined by: food production, stock levels and net trade. Global/national level.
Access: Physical, social and economic access. Economic access is determined by: incomes, expenditure, markets and prices. Often household level.
Utilization: good care and feeding practices, food preparation, diversity of the diet and intra-household distribution of food. This determines the nutritional status of individuals.

Household expenditure on food as % of income
![Page 11: Hunger in the midst of Plenty: Responses to Food ... · Responses to Food Insecurity in Israel Dana Philip & Prof. Aron M. Troen Nutrition and Brain Health Laboratory Institute of](https://reader035.vdocument.in/reader035/viewer/2022081612/5f5db92b5c2b78542e1080fd/html5/thumbnails/11.jpg)
Lower Income is Associated with Less Fruit and Vegetables Consumption
“With the decline in income, households … are likely to find it challenging to consume sufficient amounts of milk and dairy products, and especially fruit and vegetables, which are the basis for a healthy Mediterranean diet.”

NGOs Play an Important Role in National Policy
Until 2015, Israeli government left food security to the third (private) sector.
New national plan:
• Regulate third sector activity with partial funding.
• Use existing logistic infrastructure (Leket Israel and Latet)
![Page 14: Hunger in the midst of Plenty: Responses to Food ... · Responses to Food Insecurity in Israel Dana Philip & Prof. Aron M. Troen Nutrition and Brain Health Laboratory Institute of](https://reader035.vdocument.in/reader035/viewer/2022081612/5f5db92b5c2b78542e1080fd/html5/thumbnails/14.jpg)
Leket Israel • The largest food bank in
Israel.
• Treats food insecurity as a logistical problem. Reduces food loss and waste.
• An umbrella organization, distributing food to 180 partnering food agencies nationwide.

Unanswered Questions
• What are the needs of the recipients?
• Do recipients eat the food?
• Does it improve their nutritional status?
• Does it improve their subjective sense of food security?
• Does it improve their health?
• Are there any factors which influence these outcomes?

Working Hypothesis
Leket Israel makes a unique contribution to the food security, nutritional and health status of the beneficiaries who receive food distributed
through Leket Israel's partner agencies.
![Page 21: Hunger in the midst of Plenty: Responses to Food ... · Responses to Food Insecurity in Israel Dana Philip & Prof. Aron M. Troen Nutrition and Brain Health Laboratory Institute of](https://reader035.vdocument.in/reader035/viewer/2022081612/5f5db92b5c2b78542e1080fd/html5/thumbnails/21.jpg)
Additional Hypotheses
• Expected high prevalence among study population of – low income
– high number of people (especially children) living in the household
– poor health and non-communicable diseases
– food insecurity
– low diet quality including nutritional deficiencies
• Expected effects of the number of people living in the household and of income on nutritional, health and food security outcomes.

Specific Aims
• Characterize recipient population in terms of diet,
health, and food security.
• Assess recipient population’s dietary needs.
• Measure Leket’s contribution to the food baskets
and individual diet. Explore factors influencing
food basket quality.
• Find other factors influencing diet, health, and
food security.

Aims: Feasibility phase
• The specific aims of this project:
Test feasibility and optimize methodology for a full-scale, ongoing and definitive research on the recipients.

Healthy portions in food baskets are correlated with individual diet quality
• The number of healthy portions in basket and number of
people living in the household significantly predict individual Nutrient Density Score by linear regression (F(2,88)=3.738, p=0.028), with an R2 of 0.078.
• When age, gender, marital status, and country of birth were added to the model, healthy portions in basket did not significantly predict the individual Nutrient Density Score.

Discussion – Internal Validity
• Chance • Bias • Confounding • Measurement error
• Selection bias • Reporting bias • Over and underestimation • Sample Size? • NPO / LEKET effects? • Limitations
