Guiding Stars

Guiding Stars is a nutrition guidance program to help you quickly navigate to foods with the most nutritional value. Just look for the stars as you shop!

Learn More
guidingstars_guide

Guiding Stars helps consumers quickly navigate to foods with the most nutritional value. Products are assigned 1, 2, or 3 Stars, based on their nutritional content. A higher Star rating means the item contains more beneficial nutrients overall, and has fewer nutrients that are best to avoid. With over 100,000 rated foods, making nutritious choices for you and your family is now simple.

Based on the scientific consensus and informed by national or international policy, Guiding Stars has offered transparent and relevant nutritional guidance since 2006. Keep a lookout for the Stars on shelf tags throughout the store! If you don’t see a rating, no worries; not all products meet the Guiding Stars’ criteria to earn a Star rating.

FODMAP Diet

Does your stomach feel like it's in a knot after eating certain foods? The feeling may be irritable bowel syndrome (IBS), which impacts how the gut moves and digests food. IBS is a common GI issue affecting roughly 25-45 million people in the United States. Certain foods can cause can IBS symptoms such as bloating, gas, constipation, or diarrhea. To help alleviate these GI symptoms, you may have heard about the FODMAP diet.

FODMAP stands for fermentable short-chain carbohydrates oligo-, di-, and monosaccharides and polyols. These are carbohydrates found in many foods like fruits, vegetables, dairy products, legumes, and sugar alcohols. Bacteria ferment carbohydrates during digestion. Some individuals may have a difficult time absorbing these carbohydrates, which can cause excess gas and fluid to develop, leading to abdominal discomfort, pain, and changes in bowel habits.

FODMAP is a short-term elimination diet that can help identify the foods that contain these types of carbohydrates that may trigger digestive issues. During the elimination process, high-FODMAP foods should be avoided for approximately six to eight weeks then slowly reintroduced. People should track their food and symptoms to help identify problematic foods. Certain FODMAP foods may not impact people with IBS symptoms. People are encouraged to work closely with a physician and a registered dietitian. For help in the aisles, reach out to an in-store nutritionist.

What’s the research say?

A FODMAP eating plan has been shown to reduce symptoms in individuals suffering from irritable bowel syndrome, but may also plus improve mood and quality of life. However, other studies have shown inconclusive results. More extensive FODMAP studies are needed to assess the diet’s long-term efficacy.

FODMAP Foods in the Aisle

Manufacturers are answering the requests of consumers and now offering low-FODMAP products that do not contain onions, garlic, lactose, or gluten that may trigger IBS symptoms. Available products range from soups, baking mixes, cookies, and protein bites. There are two voluntary certifications for low-FODMAP food products are available from Monash University and FODMAP Friendly.

Find gut-friendly foods at Giant!

  • Enjoy Life Foods® makes allergy-friendly products that are free from gluten and 14 common allergens, has introduced low-FODMAP products such as cookies and protein bites.
  • FODY™ makes a variety of low fodmap products, including chocolate, sauces, salad dressings, and seasonings.
